High Quality House Extensions In London

Rear Kitchen Extension

A rear building extension is a simple add on to the end of the property. It can usually give approximately another 5 metres to the home. Many opt for large roof windows to let in natural light. Rear extensions mostly have flat roofs, centre pitched roofs or monopitch roofs.

Side Return Extension

This is the most common type of extension in South West London. It involves extending the building typically by 1.25m to the side. This new section will finish flush to the back of the main part of the property. The roof will then be typically flat or pitched.

Wrap Around Kitchen Extension

A wrap around is a combination of both of the above options, it extends to the side and back providing a new kitchen or living space. Our team can talk you through the options and recommend the best approach.

Single-Storey Extension in London

Planning a single-storey extension for your home? Whether it be for a kitchen, dining room, living room or playroom, it’s a great way to improve your home.

Double Storey Extension in London

If a single-storey extension is not enough space, why not consider something bigger. A double story extension will naturally be a bigger project. The result will, of course, lead to dramatically more space. For terraced houses, most two-storey extensions are often created at the rear of the property. They are often used to extend the kitchen and add another bedroom. Extending a semi-detached house often means a two-storey side return option. As with a single-storey extension, you need to consider your needs carefully before you start.

If the ground floor will be for the kitchen extension, do you need space for a utility room or storage? Will the second storey be used for an extra bathroom, bedroom or office? The function of each room will determine the end price. You’ll need to consider power, plumbing and so on.
