NU Projects Basements.jpg


Basement construction & remodelling 

With over 10 basement projects completed to date in London, our basement contractor is highly sought-after within the construction industry and has an outstanding reputation for being professional, trustworthy and always bringing in projects on time and within budget.  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.

As a modern urban environment, London and especially Fulham, Chelsea, South Kensington, Mayfair & Belgravia are areas lacking 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. 

#nu has had a considerable basement construction presence in London. Our skilled knowledge of the area distinguishes #nu as a valuable service for homeowners looking to create a more spacious family environment in their homes.

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.

Each London borough has its own particular conditions for building basements, which include producing traffic management plans,  site construction management plans, carrying out soil testing, structural engineering detailed calculations, eco-home assessments, flood risk assessments, and various other documents prepared by specialist consultants.

To obtain this documentation necessary for the planning application will cost several thousands of pounds, and for this reason, is not a job to be entrusted to the inexperienced. We have an excellent record of success in obtaining planning approvals for basement construction and are well-placed to advise you on what might be achievable at your property.
