London’s Leading Home Extension Specialist

How much does a London home extension cost?

A home, kitchen or side return extension is a great way of adding extra space and value to any property, most particularly in London, where space is at a premium.  Depending on the size and the space required, an average extension can cost anywhere between £30K to £50K and above, but this is dependent on many different factors.

Every home extension in London we complete is tailor made to that customer’s specific needs, so understandably prices can vary quite a lot. However we have produced a few examples below to give you an idea of the costs involved.

Low Cost – Side Return Extension

If your property allows for it, one of the most cost effective ways of extending your kitchen and dining area, is through a side return extension as it will provide a dramatic change to your home without a great cost.

A side return extension stretches your home into an alleyway at the side of the house. This is often a relatively small extension but can have a huge impact on the look and feel of the property.

These projects allow extra light into the property and can also make room for a “wow” kitchen diner. On average, side return extensions can cost anywhere from £35K upwards.

Mid range cost – Wrap around Extension

If you have the budget and space, you may decide to opt for a rear kitchen extension combined with a side return extension. This will give you a wrap around extension which can quickly provide a lot more space and dramatically alter the size of the home.

The extra space provided has been used for additional living rooms, or kitchen diners but really it can become whatever you want it to be.

Wrap around extensions cost approximately £55K upwards.

High Cost – Double Storey Extension

Simply Extend also offer the option of double storey extension to provide you with an even larger kitchen and extra room on the first floor.

Naturally, multi-floor home extensions in London cost more than other varieties, since building work has to be completed on two levels and there is double the space to work on.

On the flip side, more space means much more potential from the project. You could add another living area, but also an extra bedroom or two.

For a double storey extension, budget anywhere from £65K upwards depending on the size and scope of the project.

Bespoke Home Improvements

While having a house extension many of our clients also decide to do refurbishment work to other rooms in their house such as bathrooms and living rooms, saving money and hassle by having the same contractor completing the work at the same time. This also adds to the consistency of the work throughout your home, you can be sure it will all be completed to the same high standard.

Some clients also choose to complete a loft conversion at the same time as an extension to really maximise space.  Our sister company Simply Loft works alongside Simply Extend to carry out loft conversion projects for clients looking to do both types of home extension.
