Create & Convert

How about a light, bright new kitchen-diner, or your very own home gymnasium? Extra bedrooms for the kids, or a cosy sound-proof movie theatre? Capital Basements understand that there are many reasons you may be looking to construct a new basement.

We’ll make it possible, and take care of all those annoying details like planning permission, building regulations and party wall agreements. We’ll explain the structural process of underpinning and waterproofing so that you can rest assured your new basement extension will be safe and sound.

Whether you want to create a new basement from scratch, or convert an existing old basement or cellar to provide a beautiful habitable space, give us a call to discuss the project.

Results Realised

As our many satisfied clients will tell you, having a basement conversion or new basement build is life-changing. Not only do you gain extra living space, but a habitable basement also adds greatly to the value of any property.

Extending your home with a basement is a far more affordable option than selling up and moving to a larger property, especially in pricey London and the surrounding counties.

You will be able to gain more space from excavating a basement than you would achieve through a loft conversion or above-ground extension because the basement can spread out beyond the footprint of the house to extend under the garden.

There is everything to gain and nothing to lose when you have a basement constructed by professionals like Capital Basements. Why spend even another day in cramped conditions? Call us now and expand your world.
