One-way mirrors

Two way mirrors, or one way mirrors as they are sometimes called, can be made using acrylic or glass – double glazing or triple glazing for sound proofing.
One-way mirrors is very often used by marketing companies in their offices. When testing a new product, the professionals can watch from behind a one-way mirror the reaction of people taking part in the survey. Together with double glazing and sound proofing, all you can see from one side of the wall is a mirror.

Our building company refurbished an office in Central London and the clients asked for a room to be converted into a one way mirror. They started by remodelling the interior of the office.
builders carpenters building partition walls
The London carpenters built the partition walls, framing the new wall that will divide the room, one smaller sized room for the observers and a bigger room for those to be observed.
partition wall frame carpenters
The partition wall was then insulated and sound proofed, making sure that there are no gaps left for the sound and light to travel through. Dry lined with one layer of sound proof plasterboard and one layer of fire proof 12.5 mm fire resistant gypsum plaster board. The walls were skimmed with Multi-finish plaster by the plasterers and then painted and decorated to match existing walls.

The glazier then fitted the glass panel and the one way mirror layer.
interior one way mirror
A one-way mirror, also known as a two-way mirror, one-way glass, or two-way glass is a mirror which is partially reflective and partially transparent. When one side of the mirror is brightly lit and the other is dark, it allows viewing from the darkened side but not vice versa.
When such mirrors are used for one-way observation, the viewing room is kept dark by a darkened curtain or a double door vestibule. These observation rooms have been used in:

Interrogation rooms
Execution rooms
Experimental research
Security observation decks in public areas
Market research
Reality television, as in the series, Big Brother, which makes extensive use of two-way mirrors throughout its set to allow cameramen in special black hallways to use movable cameras to film contestants without being seen.

London Electricians in London

In London, most houses are powered by old electrical wiring. The electrification in Great Britain and London, started from 1870, when some middle-class home owners and shops started to use the electricity in order to reduce the risk of fire and for its reliability compared to gas light. In 1929 about 20% of London homes were electrified.

With new building regulation, old electrical wiring can be illegal as it can be dangerous. Electrical wiring fires start due faulty wiring or old outlets.

If you are looking for a qualified electrician, London Electricians cover most of London. Flats re wiring, House re-wiring, new consumer units. fuse boxes, sockets and lights, electrical underfloor heating, commercial and domestic.
london electricians rewiring
First thing an electrical system needs is an up to date Consumer Unit or a Fuse Box. The old types of Consumer Units, used to be very rudimentary, providing very little protections to the electrical wiring. The fuse itself was just a wire fitted into a ceramic unit, between two copper blades acting as fuse wire.
new fuse box consumer unit

The new Consumer Units, uses RCD’s (Residual Current Device) that cuts the power off if needed as safety measure.The fuses are Circuit Breakers which helps protect a ring circuit.
Sometimes when a house extension is added to a house for example, an MCB ( miniature circuit breaker ) can be install if necessary, if the Fuse Box is not capable to deal with the extra electrical overloading.

Glass floor and ceiling, supplier and installers

When you need natural lighting or just a cool feature, a glass floor that you can walk on it, is the ultimate lightwell for basements, flats and houses, offices, commercials properties, and in the entertainment buildings. And you can walk on it after you get used to ”walking on air feeling”.
glass floor that you can walk on it
Using small panels – glazing units can create a larger floor or ceiling space area, transforming the floor or the ceiling into a visual open space to great effect. Interior Designers are using the glass floors to maximize the feel and look of a building.
glass floor ceiling

The glass floor can be sandblasted for a non-slip surface or frosted ( obscure ) for privacy. In the picture below, you can see the sky- literally – from the first floor through a glass floor and a roof window. The natural light can find its way from the roof level to a basement.
glass ceiling flat
The roofers first had to install the Velux window in the roof, by creating an opening in the right place and install the sky window. A second opening was made between the top floor and first floor, where the glass floor was to be installed. Then the glaziers fitted the glass floor/ceiling glass into the metal frame.
Another option for natural light is a sun tunnel. Fire-rated glass floors are also available and recommended to be used in both domestic and commercial properties. For London flats and houses, a glass floor can transform the property into a modern property.

Roofers in London, Lead Roofing

Roofers in London, Lead Roofing. Our roofers are Lead roofing specialists when it comes to lead roofing.One of the oldest and most durable building materials. Lead can last for centuries if maintained properly and it is used widely in roofing and plumbing. Lead pipes are not recommended to be used anymore due to toxicity and if you have lead piping, you should consider replacing them to a healthier alternative such as plastic or copper pipes. Lead is soft and durable as a metal roofing material, used in buildings since Roman times, and recently lead roofs are becoming increasingly expensive to insure due to high cost of lead. A church and a school in UK had the whole lead roofing stolen by thieves.
lead roofers london
In Europe, lead roofing plays a major part in the Architecture and Design of most buildings. The traditional arts of construction and craftsmanship are guarded by strict laws when the property is a Listed building or in a Conservation Area.
lead roofing conservation area
The most common type of lead roofing is the rolled lead sheet and it is classified by the British and European Standard. Most used rolled lead in roofing are codes 3, 4, 5 for soakers, roofing, flashing but it can be custom ordered in any size or thickness.
Listed building roofing roofers
Sand Cast Lead is used for very special building projects,historical buildings, museums, etc.It can be processed for colour and texture when required. The size and thickens are usually from code 6 to 12.

Specification Clauses

The advisory service is based at the LSA’s Technical Office in Kent, and is there to provide technical guidance and assistance to help others obtain the best performance from BSEN 12588 rolled lead sheet. Technical officers are there to be consulted and offer independent advice and guidance, based on many years of experience, which has been developed through on-site investigations and research, into the performance of an outstanding long enduring roofing and weathering material. The following clauses will be of particular value to Architects and Surveyors.

MA – Materials and Accessories

M1 Type and thickness of Lead Sheet
Lead sheet shall comply with the requirements of BS EN 12588 for lead and lead alloys-Rolled lead sheet for building purposes.
MA 1 Clips
The free edge of the lead flashing must always be ‘adequately clipped’ to prevent lifting and distortion in high wind conditions, Adequate clipping will depend on the location, orientation and exposure of the building and these, in turn will determine the material used for the clips, their spacing and, most important, the method of fixing. Clips should be spaced at between 300 and 500mm centres depending on exposure. For sheltered exposures clips fixed at the top (as in Fig.1) with a clip at each lap joint and at about 500mm centres will be adequate. However in more exposed situations, this method will not prevent wind lift in storm conditions and additional restraint will be needed. The important principle: ‘the lower the fixing the stronger the clips’ is illustrated in Fig.3. A typical example of extra fixings to clips is shown in Fig.2. Therefore, although the spacing and the material used are important, the method of fixing is an essential factor to be considered if the clips are to provide effective resistance to wind lift in storm conditions.
Clips should be of copper, tinned copper, stainless steel or lead.
MA. 1.1 Copper clips
Copper or tinned copper clips should be not less than 50mm wide and cut from copper sheet of not less than 0.60mm thickness, conforming to BS EN 1172. Soft temper in welts, seams and rolls and of ¼ H temper elsewhere.
MA.1.2 Stainless steel clips
Stainless steel clips should be cut from 50mm wide fully annealed stainless steel strip of not less than 0.375-mm thickness. The strip should conform to BS EN 10088. It may be terne coated if exposed to view. For high exposure situations a thicker sheet (0.46 stainless steel) should be used.
MA. 1.3 Lead clips
Lead is only suitable for clips in sheltered locations. The thickness of the sheet used should not be less than the thickness of the flashing.
Lead clips should be not less than 50mm wide and not less than the thickness of lead sheet used for roofing and cladding work

MA 2 Nails
MA 2.1 Nails and sizes
Generally nails should be of copper or stainless steel and should be clout nails conforming to BS 1202-1 and -2. The shanks should be annular ring, helical ring or serrated. Nails should also be not less than 20mm long. For heavy-duty fixings they should be not less than 3.35mm diameter and for light duty they should be not less than 2.65mm diameter, the nail head being approximately three times the shank diameter.
MA 2.2 Stainless steel nails
Stainless steel nails should be of austenitic stainless steel, excluding free machining grades.
MA 3 Screws
Screws should be brass or stainless steel conforming to BS 1210 and not less than 20mm long.
MA 4 Underlays
The type of underlay selected for use with lead sheet should:
Allow for thermal movement by reducing the amount of drag between the substrate and the lead sheet;
Help protect the lead sheet by providing a barrier against corrosive attack from stone, concrete or discharge from timber and roof condensation;
Provide an even surface and level out any imperfections such as nail heads, board edges and knots which could damage the lead;
Fully support the lead sheet so that it cannot sag or be punctured;
Provide a sound reducing layer in periods of heavy rain;
Reduce the risk of moisture being trapped between the lead and the substrate;
Be free of any substances, which could be deleterious to the lead sheet.
Typical underlays that could be considered are:
Class A building paper conforming to the requirements of BS1521.
Non-woven needle punched polyester geotextile that has a weight of not less than 210/mm2 (+ or -5%)
MA 5 Solder
Solder should conform to BS EN 29453.
(Generally solder is only used for soldered dots or where lead welding or bossing is impracticable.)
MA 6 Patination of external leadwork.
In rainy or damp conditions new lead sheet flashings will produce an initial, uneven white carbonate on the surface. This can be aesthetically unacceptable in some situations but, more importantly, the white carbonate can be washed off by rain to cause unsightly staining on materials below flashings. To reduce staining and also provide a pleasing appearance, lead sheet should be treated as soon as practical after fixing and preferably the oil should be applied no later than the end of the day’s work. It is important to apply a coating under the lower edge of leadwork and between the laps. Clips along the edges of flashings should be turned over after application of the treatment.
There are two types of treatment, solvent based and water based. Whatever type is used, to obtain the best results it is important to follow the manufacturers’ instructions.

FR – Joints in the leadwork.

FR1. Wood cored rolls are suitable for flat roofing, pitched roofing and vertical cladding and are positioned in the direction of the fall except at ridges, hip intersections and high points in gutter linings. Wood rolls are acceptable for use where there is likely to be foot traffic. Typical specification clauses may be written as follows:
FR1.1. Joints running with the fall to be wood cored rolls and the overcloak detailed with a 40mm splash lap. Rolls to be positioned inline and spaced at…….mm.centres for code…….

FR 1.2. Joints running with the fall to be wood cored rolls and the overcloak detailed with a 40mm splash lap. Rolls to be staggered and spaced at…….mm.centres for code…….

FR 1.3. Joints running with the fall to be wood cored rolls and the overcloak detailed with a 25mm return welt and clipped within the welted edge with 50mm wide copper clips at 450mm centres. Rolls to be staggered and spaced at…….mm. centres for code…….

FR 1.4. Joints running with the fall to be wood cored rolls and the overcloak detailed without a splash lap. With the free edge terminated between 3-5mm above the roofline Rolls to be staggered and spaced at…… centres for code……. (Codes 7 & 8 only)
FR 2. Drips are used across the fall for roofs at minimal fall of 1 in 80 and up to 10 degrees. They are also used in lead lined box, parapet and centre valley gutters. The minimum height for drips is 50mm, 55mm for drips in conjunction with rolls using codes 4, 5 and 6; and 60mm for codes 7 and 8.
A typical clause would be:
FR 2.1. Joints across the fall to be drips……….mm in height with the underlap dressed into a 25mm minimum wide rebate and secured with a single row of nails at 50mm centres. Form overlap to provide a 40mm splash lap.
FR 2.2. Flat Roofs with a gradient of between 30 and 100 will require extra fixings on the flat area immediately in front of the drip. A typical clause would be:
Joints across the fall to be drips……….mm in height with the underlap dressed to the full height of the drip upstand. The head of the bay abutting the drip to be secured with two rows of nails. The rows to be 25mm and 50mm from the face of the upstand with the nails spaced at 75mm centres in a staggered pattern. The heads of the nails to be sealed by soldering or lead welding to ensure the fixings will be watertight. The overlap from the upper bay to be formed with a 75 mm splash lap, and secured with……no. lead clips lead welded to the under lying sheet, (Insert number of clips See paragraph MA1)

PR1. Pitched Roofs at between 11 and 80 degrees.

For chart showing spacing of joints see page 2/6Typical clauses as follows:
PR 1.1. Joints running with the fall to be wood cored rolls and the overcloak detailed with a 40mm splash lap and rolls spaced at…….mm.centres for code…….

PR1. 2. Joints running with the fall to be wood cored rolls and the overcloak detailed with a 25mm return welt and clipped within the welted edge with 50mm wide copper clips at 450mm centres and rolls spaced at…….mm. centres for code…

PR1.3. Joints running with the fall to be hollow rolls and detailed with 50mm wide copper clips within the rolls at 450mm centres with the rolls spaced at…….mm. centres for code…….
PR1. 4. Joints across the fall to be overlaps…………mm in length with the free edge clipped with …….No. 50mm wide lead clips lead welded to the under lying sheet, (Insert number of clips See spec on clips**)

PR1. 5. Joints across the fall to be overlaps…………mm in length with the free edge clipped with …number. 50mm wide ………………. clips secured with ………nail fixings, (Insert number of clips and whether copper or stainless steel is to be used. See paragraph MA1)

G1. Gutters linings.

Lead-lined gutters are used where a lead-covered flat roof, or a tiled or slated roof, is designed with a parapet wall. They are also used where a flat or pitched roof abuts a vertical wall, where two pitched roofs are joined by a horizontal valley gutter, and between adjacent areas of lead roofing. To allow for thermal movement, lead gutter linings must always be divided into separate pieces (bays).

The size of a piece of gutter lining will depend on the thickness of lead sheet used. Table 7 shows the maximum length and girth for the five codes of lead sheet normally used for lining both box and tapered gutters.
Although Code 4 is the minimum thickness for gutter linings, its use is recommended only for very short gutters, because the maximum drip spacing of 1 .5m is usually uneconomical when compared to using Code 5 with drips at 2m centres.
To accommodate thermal movement, drips are used across the fall for both box and tapered gutter linings
For chart showing spacing of joints see page 2/6

A typical clause for gutter linings would be:

G1.1. Lead lined parapet gutters.
Typical clauses may be:
G1.2. The width of the box gutter shall be not less than 225mm. The gutter lining shall be formed in
Code …….. lead sheet divided into bays in lengths not exceeding ……….mm with drips not less than …….mm deep. (Refer to the chart in section 2/6 for codes, thicknesses and maximum sizes.) Where the girth of the gutter exceeds the maximum recommended, one or more wood cored rolls will be required to divide the gutter.

F1 Abutment Flashings

Typical clauses for flashings could be:

F 1. Apron flashings at lean-to abutments in code………in lengths not exceeding …….mm with end to end lap joints of not less than 100mm. Upstand to the abutment not less than 75mm and with a lap of……….mm over the pitched roof covering. The 25mm turn in to the masonry joint to be lead wedged at laps and at 450mm centres, prior to pointing. The free edge of the flashing to be clipped with……..clips spaced at…… ..Centres (Insert spacing of clips and whether copper or stainless steel is to be used. See paragraph MA1)
F 2. Step flashings in code…… in lengths not exceeding 1500mm with end-to-end lap joints of not less than 100mm. The 25mm turn in to each step to be lead wedged prior to pointing.
F3. Soakers
Soakers shall be formed from code…….. lead sheet with a minimum upstand at the abutment of 75mm and a lap of not less than 100mm over the tiles or slates. The length of the soaker to be equal to the gauge plus lap plus 25mm.
F4. Single step flashings. Individual step flashings to be cut from code…. …with a minimum-passing lap of 50mm between each single step, covering over the upstand of soakers or cover flashing by not less than 65mm. Each step to be turned into the brick joints by 25mm and secured with lead wedges on every course. The width and length of the steps to be calculated on site to suit the pitch of the roof and type of brick or stonework encountered.
F5. Step and cover flashings in code… in lengths not exceeding 1500mm with a passing lap of not less than 150mm between each section. Each step to be turned into the brick joints by 25mm and secured with lead wedges on every course.

Insulation for lofts and cavity walls

It might sound amusing but British Gas offers rewards to find uninsulated homes. Basically, you could get 50 pounds if you spy on people and pass on the name and property address to Energy companies. While the intention behind the unorthodox move is quite beneficial ” loft insulation can save households £175 on their heating bills and cavity wall insulation can save £135” the moral legality of spying on peoples lofts might be considered a dubious practice.

Heat loss from an uninsulated home:
Walls 33%
Roof 26%
Windows 18%
General draughts 12%
Floors 8%
Doors 3%

insulation heat loss
The government insulation targets, are forcing the Energy companies to find more homes with no insulation, yet in London at least, it is very unlikely to find a loft with no insulation at all.
Buying an infrared camera, and driving around, you could actually make some money out of this. Thermal camera identifies heat loss – Identifies heat loss through poor insulation, locate excessive air leakage and can be an extremely useful tool in the building industry.

Top Ideas For Modern Bathrooms

Modern bathrooms feature clean, minimal lines for a streamlined look and with careful planning and attention to detail you can create a bathroom with plenty of style combined with functionality. A modern bathroom will also be a place that you will be able to relax in and ease away your stresses.

An increasingly popular choice for modern bathrooms is to include bathroom furniture in your design so you have somewhere to store toiletries away from view creating a clutter free space. Bathroom furniture is available in a wide range of finishes and sizes to suit every size and shape of bathroom, whether you have a large bathroom or a more compact space. Wall-hung vanity units are great for creating a very modern look and will provide the illusion of more floor space, which is perfect for a bathroom with limited space. Bathroom furniture is also a great way to add colour and texture to modern bathrooms and can create a space that meets your exact needs.

Wall-hung toilets and basins will provide a very contemporary look to modern bathrooms and are ideal for small bathrooms. A wall-hung toilet and basin will provide an ultra-chic look and will make cleaning the floor so much easier too.

If you have the space opting for a luxurious freestanding bath will create an eye-catching feature in a modern bathroom and will provide you with an indulgent soak. Double-ended baths are also a great choice for modern bathrooms and because the bath taps are positioned in the centre of the bath it allows you to comfortably bathe at whichever end you wish.

For an ultra-sleek look to a modern bathroom think about including a walk in shower enclosure, which will provide the room with a touch of designer style. Walk in shower enclosures are ideal for replacing an existing bath and will create a minimalistic feel helping to enhance a feeling of space. Walk in showers are also ideal for people who lead busy lifestyles and offer a fantastic convenient showering solution. Walk in showers will create a real style statement in any modern bathroom.

With the right details a modern bathroom can look simply stunning, make sure you choose some striking brassware, which can help to add a real feature point to the room and provide them all important finishing touches. When choosing bathroom taps for a modern bathroom take into consideration the overall shape of your bathroom pottery and select a style to reflect the design, for example if you have a basin with angular lines a basin tap with a square design will complement the basin perfectly. To bring the modern look together and to turn the bathroom into an inviting space a designer radiator will make the perfect addition to any modern bathroom.

Chelsea Plumbers,Chelsea plumbing job

A customer bought a flat in Chelsea, London. A very good size flat but in need for a new plumbing system. Because the flat was in the London borough of Kensington & Chelsea, the plumbers couldn’t get a parking permit for traders unless we applied for an expensive parking bay suspension.

As most plumbers have a large amount of materials and heavy equipment, tool boxes and heavy parts like boilers, and parking the van was possible only in a pay and display bay, a good distance from the Chelsea flat where the plumbing job was, lets say that it wasn’t an ideal situation for the plumbers. Together with the congestion charge, a single van for the plumbers would cost over £ 120.00 per day, parking and transport.
vans plumbers robuild

The plumbers in Chelsea have a hard time finding a parking space, feed the meters and do the plumbing jobs at the same time. Then the job became more complex because the bathroom and kitchen needed to be redone too.

The plumbers removed the old boiler and the water tanks ( conventional central heating system ) and after a discussion with the flat owner, the plumbers decided not to install a megaflo system, but a high flow boiler, capable to run the two bathrooms and kitchen at the same time.

boiler highflow pipes

By not installing a megaflo central heating system and boiler, the plumbers saved some space that otherwise would have been taken by the unvented cylinders hot water tanks.

After the boilers was installed and tested, the plumbers proceeded to run the new plumbing for the kitchen and bathrooms and install the sinks, basins, taps, waste pipes, bathroom and kitchen units.

House Extension Builders, Electricians, Roofers and Plumbers in Acton, West London

Building a house extension in Acton, West London

This two story side extension and return one story kitchen extension was build in East Acton, West London.

house extension in Acton, west London

Because the property already had an old kitchen extension, we had to obtain Planning Permission from Ealing Council before we started the works.

The Architect did an outline Plan/Drawing to submit to the Planning Department before working on the Full Plans. The Planning Permission department can advice sometimes what type of house extensions are most probable to approve. When they said that the extension needs to be pushed back with one meter from the main street, the architect submitted a new drawing and got the green light for the building works to start.

We were recommended to the customer by the Architect as London Builders have been working in the past with him on previous jobs and our Quote was accepted by the client.

Because the owner has a family and moving out of the property while the builders are carrying out the building works, we decided to build the house extension without breaking up the walls to make the new openings or disrupt they daily life too much unless necessary.

Right in front of the Proposed House Extension, an exotic tree was planted years ago and the owner insisted to keep the tree the way it is.
tree close to house extension
Having trees close to a new building, affects the foundation, so we had to find out how deep the roots for this type of tree can go. Together with the Building Inspector, we decided that a foundation of 2.5 meters deep is what is needed, compared to a standard 1.2 meters depth.
After demolishing the existing brick wall fence, the ground workers started to mark the foundation and measurements.
setting out foundations
The gas meter was eventually moved to the front of the building.
gas meter moved
Easy access to the building site, allowed for a small mechanical digger to be used, making the job easier, faster and cheaper.
small digger foundation
The builders digging the trench for the foundations were making good progress, the ground workers decided the use plywood to cover the drive way to protect the surface and used to deposit the soil from the foundation onto the driveway. Grab lorries were used instead of skips, cheaper and faster labour time frame.
driveway soil foundation

After a small delay due to an old Victorian sewer clay pipe, the ground workers finished the foundation, and with the approval of the Building Inspector, the footings for the new extension was completed.

The bricklayers could now start building the side extension walls. They started by building the under DPC walls, the blockwork is considered to be part of the foundation if it is under the DPC level. ( damp-proof course )

Parking in Acton is not easy, but a nearby pub parking were kind enough to let the bricklayers park their van from 8 in the morning till 5, so we would like to Thank them.

Trying to match the bricks to the old building was done as close as possible.
brickwall building
The brickies used the same type of bricks, but because new bricks look different to the weather down original bricks, making the new brick wall looking brighter. There was the option to use reclaimed second hand bricks but customer decided to have new ones, hoping that in time they will look the same.
matching brickwork

The size of the extension was quite narrow and long. In West London, space to build a house extension is at a premium.
side extension size

Two types of bricks were used, the side walls were built using plain London Bricks.
London Bricks

The walls are cavity walls, bricks on the outside and block/breeze thermal thermalite blocks on the inside.

The joiners started the joist work for the first floor, so that the floor space can be used by the bricklayers to deposit bricks, cement mix mortar , blocks and other materials.

The extensions walls 90% completed

When most of the house extension wall were completed, the RSJ metal beam for structural openings could be installed.

The metal beam allowed for the external corner walls of the original house to be removed and in this way, an open plan kitchen and dining room to be created.

The RSJ beams are sitting on concrete pad-stones, painted in intumescent paint and encased in fire proof casing.

When this was done, the plumbers, electricians, plasterers and carpenters could start working on the plumbing, roofing, electrics and plastering.
