Basements Conversions

London is tight for space and every inch comes at a premium price. Are there other ways in which you can extend your London property that you haven’t even considered?

Have you considered extending downwards?

Turnkey building contractors can convert your basement into a space you can really utilise for your needs. Whether you need basement excavation, basement construction or basement conversions we will be able to help you from design right through to completion. You do not need to move out of your London home because there is not enough space, you can extend downwards and create the home size that you need for your growing family.

What can I use my new London basement for?

There are many different things you can turn your London basement into. You name it, there are so many things you can do with your London basement. We thought we should share some ideas that our customers in London love doing to their basements:

Guest room

When you have guests staying, giving them a separate part of the house where they can have their privacy is ideal. Turning your basement into a guest room with a bathroom and perhaps even a lounge area will make them feel at home.

A home bar and games room

Would you like somewhere different to entertain your guests? Turning your London basement into a home bar with a games room will wow your friends. You won’t want to hit London town in the evenings anymore.

Cinema room

The kids will love it, and it’s a great space for the whole family to spend some time together.


Giving the kids some more room to spread out gives them space to let their imagination soar.

Arts studio

What every artist dreams of is a dedicated space for their art practice. This is a fantastic way to use the space in your basement.


A basement gym saves you both time and money.
