Why Basements are a Critical Aspect of Building in London

Homeowner, developer, commercial investor, a professionally built basement allows you to create whatever you can imagine, whether it’s the living space you always dreamed about, spaces for storage, utilities, or private health facilities. But behind every lovely basement is a firm foundation of know-how, accuracy, and creativity required.

FAQs
How long does it usually take to build a basement in London?
It varies, depending on the size, complexity, and location of the project. The typical residential basement, from excavation to completed project, is 2-5 months. GWD Services’ project management customises the project timeline at the planning phase to ensure transparency and accuracy.
Is planning permission required for a basement in London?
In many cases, especially if a basement means structural alterations, major excavation, or affects the appearance of the building from the outside. GWD Services collaborates with architects and the local council on all aspects of the planning process for a smooth progression and full confirmation.
How do you protect the structure by waterproofing?
All our basements are constructed using RC techniques and state-of-the-art waterproofing systems to guarantee that they remain water-resistant throughout their lifespan. We adhere to high building regulations and engineering practices, so we deliver rock-solid watertight results every time, all the time!
Is building a basement under an already built structure possible?
Yes — it is a complicated task to retro-build a basement under an existing building, but this is always possible with the appropriate design and construction knowledge. GWD Services has operated on live sites and within occupied commercial and residential buildings for decades, constructing difficult retro-build basement projects in and around London.
