Foundations for home and house extensions

Foundations for home extensions and house extensions are extremely important. The footings for a new home extension can pose a danger, not only to your home, but the neighbour’s house too.

Home extensions often cause some sort of conflict with the neighbours.
But residents living near this piece of botched building work might have complained a little more vigorously had they foreseen the results.
The extension to the semi-detached houses in Wolverhampton did far worse than just block out extra light – it looks to have caused the adjacent home to crumble.
The house collapsed into its foundations early this morning after work on the neighbouring property is believed to have made the ground unstable.

Most excavations close to boundaries ( 3m rule and 6m rule) are covered under the Party Wall Act, with notices having to be served by the developer on the neighbour. Providing what the developer is doing is technically sound the work can in due course proceed. The DIY world avoid this like the plague, and most will not know or bother with it, as it is viewed as an unnecessary and easily avoidable cost.

A good and safe practice for house and home extension builders when digging foundations for extensions in a very populated urban area and with properties very close to the new foundation is to use foundations walls support as soon is possible.

Because of Building Regulations, a builder or a ground worker can not pour concrete and cement without a Building Inspector approval, as the footings for a new building needs to be inspected. The foundation work can take sometimes up to two weeks before is completed, and in most cases the Building Company or the builders, will make an appointment with the Building Control Inspector a day before ordering the ready mix concrete or starting pouring concrete if the concrete is mixed on site.

Even when the soil is stable and the ground looks very solid, the foundations needs to be reinforced very quickly. Using external grade plywood, 22 mm and noggins, helps stabilizing a foundation before the concrete is poured into the footing trench. If necessary, mechanical equipment can be rented or hired.

House extension

There are many reasons for building a home extension or a house extension in London,the most common one is to create more habitual living space. Buying a new house or moving to a new location is not always an option, and if more living space is needed, adding a home extension can be the right solution. It also ads value to the property.

Size does matter, single storey extension or double storey extension

If you don’t have the space or finance for a double storey extension, then a single storey extension could provide you with an extra bedroom, living room, kitchen and bathroom. Cheaper and faster to build than a two storey extension, one storey extension also limits the time you have to put up with builders working on your property. After few months of noise, dust and stress, you will appreciate some quiet and relaxing time within the confines of your home.

Planning Permission might not even be needed if the house has not been extended before and the loft or garage has not been converted. However, you will need to apply for Building Regulations and there is a fee to be paid to your Local Council, Building Department.

You can always have a single storey house extension built with a two storey house extension in mind. The foundation needs to be deep enough and the openings to be bridged with strong lintels and metal beams (RSJ) designed for a 2 storey home extension – to withhold the future weight of a double storey home extension.

Kitchen Extension are very common and popular in London for its terraced houses. Not many London’s homes have a side garage or space for a side extension, sometimes even those semidetached houses. The only way for a terraced house to be extended is into the garden – a rear extension or kitchen extension and by converting the roof space into a Loft Conversions.

Planning and Designing a Kitchen Extension

It is always advisable to employ an Architect, however, if the Kitchen Extension is simple in design and layout, it is not absolutely necessary, thus, you can make a small saving of few hundreds of pounds. We can draw an outlined plan for you, in 2D and 3D, using an architectural software.

If the Kitchen Extension requires walls to be removed in order to make new openings, a Structural Engineer ( Civil Engineer) and Structural Calculations are needed.

Metal work or Metal Beams ( RSJs beams ) are needed for the structural work.

The technical Specifications are also important in order to give an accurate quote or estimate for the building works.

Planning Permission, Building regulations & permitted development for a Kitchen Extension

Before, homeowners could expand their property by a total of up to 70 cubic metres – or 50 cubic metres for a terraced house – before having to apply for planning permission. This allowance had to be divided up between any extensions and loft conversions. Anyone wishing to expand further was forced to apply for permission from their local council. Now, as well being able to have a loft conversion of up to 50 cubic metres without planning permission, families are free to build a two-storey extension stretching back 10ft from the rear of their house, with no limit to its total volume.

Building Regulations are needed regardless of Planning Consent. Before starting the work on the Kitchen Extension, the Building Control Department (from the Local Council) requires a Building Notice to be submitted, together with a fee ( between £300.00 and £600.00 ), three working days before the building works starts.

New Planning Permission rules

Planning Permission

This guidance reflects temporary increases to the size limits for single-storey rear extensions that must be completed by 30 May 2019, and the associated neighbour consultation scheme.

An extension or addition to your house is considered to be permitted development, not requiring an application for planning permission, subject to the following limits and conditions:

No more than half the area of land around the “original house”* would be covered by additions or other buildings.
No extension forward of the principal elevation or side elevation fronting a highway.
No extension to be higher than the highest part of the roof.
Single-storey rear extension must not extend beyond the rear wall of the original house* by more than three metres if an attached house or by four metres if a detached house.
In addition, outside Article 2(3) designated land* and Sites of Special Scientific Interest the limit is increased to 6m if an attached house and 8m if a detached house until 30 May 2019.
These increased limits (between 3m and 6m and between 4m and 8m respectively) are subject to the prior notification of the proposal to the Local Planning Authority and the implementation of a neighbour consultation scheme. If objections are received, the proposal might not be allowed.
Maximum height of a single-storey rear extension of four metres.
Extensions of more than one storey must not extend beyond the rear wall of the original house* by more than three metres.
Maximum eaves height of an extension within two metres of the boundary of three metres.
Maximum eaves and ridge height of extension no higher than existing house.
Side extensions to be single storey with maximum height of four metres and width no more than half that of the original house.
Two-storey extensions no closer than seven metres to rear boundary.
Roof pitch of extensions higher than one storey to match existing house.
Materials to be similar in appearance to the existing house.
No verandas, balconies or raised platforms.
Upper-floor, side-facing windows to be obscure-glazed; any opening to be 1.7m above the floor.
On designated land* no permitted development for rear extensions of more than one storey.
On designated land no cladding of the exterior.
On designated land no side extensions.

* The term “original house” means the house as it was first built or as it stood on 1 July 1948 (if it was built before that date). Although you may not have built an extension to the house, a previous owner may have done so.

* Designated land includes conservation areas, national parks and the Broads, Areas of Outstanding Natural Beauty, and World Heritage Sites.
