From new-build basements to complex basement and cellar extensions, Stockbridge can guide you through the process of creating more space within your property.

Stockbridge Design & Build has the expertise and project management experience to oversee all basement excavations, constructions and conversions.

This includes creating new-build basements, as well as managing basement extensions and cellar conversions, incorporating the wealth of environment-control measures, such as waterproofing, insulation and ventilation.

And, as a company that works in some of London’s prime locations, we have the know-how to create luxury basements of almost any size in both commercial and residential properties.

Whether part of a shell and core package or a complete contract solution, Stockbridge can bring together the appropriate architectural, planning and design expertise for even the most complex basement project.

Having gained a sense of its intended use, we can guide the project through its initial design and planning process, which typically includes the production of design drawings and the commissioning of pre-application investigations, such as tree reports, noise surveys and flood risk assessments.

Once your scheme has received planning approval, we take your proposal through the detailed design and engineering stages, before going on to manage its construction.

As an experienced construction company, Stockbridge can also build multi-level basements. Basement options available include:

Retrofit (under-house)

This involves excavating below an existing building, whether it has a cellar or not. Basements can be built to a specific area or below the property’s entire footprint, depending on the amount of space required. This can also be extended outwards as part of a larger above-ground extension.

Basements can be a useful option where a client has already exhausted their other extension options at their current property. Extra space can be used as plant rooms, wine cellars, swimming pools, storage areas and garages.

Open excavations

Where clients wish to extend or construct a basement beyond the existing property’s boundaries, Stockbridge can excavate and extend out below gardens or open land. These can be for single- or multi-level basements, depending on the client’s requirements and prevailing planning restrictions.
