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.

Demolishing an old conservatory and building an extension

Sometimes, building a small extension can be done very cheaply if the new extension can make use of three existing walls. You might not need Planning Permission, but you must apply for Building Control by submitting a Building Notice and pay the required fee. Note: if you submit the Building Notice but you do not pay the fee – the Building Notice is ignored by the Council.

Because there are already three existing walls, the old property and the neighbour’s extension wall, in this case we have an U – shaped site. After getting the neighbour to sign the Party Wall Agreement, the wall can be used as part of the new extension.

Infill extension

Due to a tree close by, the Building Control asked for the foundation to be 1.5 deep.

Because the foundation was small in size, mixing the concrete needed to fill up the footing was done by hand.

The trench does not have to be filled up to the rim, it can be done bellow the ground level. Just make sure is levelled, it makes the bricklayer’s job easier.

For this particular home extension, the roof is a flat roof ( warm decking – warm roof ). You can also see the brickwork bellow the DPC level ( damp proof course )

The flat roof is covered by fibreglass and for the light we installed a Velux window right in the middle of the roof.

Having a large roof window installed, will provide natural light.
