Why build a basement

Basement contractors in London. We design, engineer and build basements under one contract. Basement cost in London, the 2026 figures.

My name’s Nick Jeffries of NU Projects in Fulham. We specialise in extensions, and especially in basements. Here are two reasons to consider one.

First, you can create that extra living space under the ground you’ve always wanted. Maybe you don’t want to sell your house. You want to stay where you are. You want to create that extra space under the ground. You can put whatever you want down there. That includes bedrooms with en suites, utility rooms and storage. It also includes a cinema room, a playroom or a self-contained flat. Extra bedrooms change what the house can do. We usually put in a 2.8 to 3 metre ceiling height. It does not feel like a basement when you get down there. Lightwells at the front and the back bring the daylight in.

Number two, I think, is the floor area. It is the more important one. You could probably put a basement in an average West London terraced house. It would be 700 to 1,000 square foot. That is another whole floor.

Whether that money comes back when you sell depends on two things. One is what finished space is worth per square foot in your postcode. The other is what the build costs on your particular ground and access. Nobody can promise you a return on it. Anybody who quotes a percentage has not seen your house. Our own basement rates by specification are published in the NU Build Cost Calculator. You can do the arithmetic yourself before you speak to anybody.

The build cost covers the professional fees too. These are architects, structural engineers, building control and some interior design.

If you have any questions, please contact me today.
