The most ambitious space in a home is often the one you can't see from the street.

Basement projects are among the most technically demanding builds we undertake. From underpinning and waterproofing to natural light and ventilation, we manage every specialist discipline to deliver dry, comfortable, genuinely usable space — engineered for the long term and finished to the same standard as the floors above.

By far and away the best builders we've ever used. Phil, Katie and the team are professional, friendly and responsive… We will always use Phil and the team for building projects in the future – I wouldn't put my house in the hands of anyone else.
