Basement excavation


 As a modern urban environment, areas in London lack natural space. For property owners, often, the only realistic option in producing this extra space is by digging a basement under the footprint of their home.  


From single, double or triple basements, using underpinning or piling, the team has the experience & the know-how to ensure the project runs safely & without any movement or damage to the neighbouring properties.

​Should you wish to gain extra space in your property via digging down to your basement, in order for you to accommodate a new gym, golf simulator, home SPA, cinema room, or just extra bedroom with an en-suite, we would gladly assist you. Our expertise in building basements is second to none, having all the knowledge and experience required.

FrontierstroyUK have a considerable basement construction presence in London. 

We have successfully excavated and developed the basements for many clients to create bedrooms, utility rooms, cinemas, wine cellars, swimming pools, gyms, saunas, and self-contained flats, which have added significantly to their peace of mind when living in the properties.​
