Basement Construction

Your basement offers so much potential to expand your property. Work with our experienced basement specialists to achieve the result you deserve.

Enhance your property with the help of basement contractors, creating a functional space underneath your building.

Basement construction allows us to safely transform the space under ground or under the original footprint of your property to create an additional level which is suitable for living. Although we predominantly undertake basement construction in London, we also work in surrounding areas and across the South East of England.

Our staff are fully supported and enabled to deliver the project for our clients in a timely and cost effective manner. With every basement construction we undertake, a main project manager will be allocated depending on their specialisms. They will take ownership of that specific conversion project or under garden basement UK, ensuring that the entire team are working to the same high standards.

As well as having the ability to transform existing basements to transform the unused space, our basement contractors can build new space below ground level to create an under garden basement UK.

Whether you aspire to create a storey below ground level or even two, our basement construction specialists are experienced undertaking solutions for cleared development or commercial sites.
