    London Basement Extensions: Technical Design

    The technical design of basement extensions is critically important, as is the co-ordination between architect and structural engineer in the preparation of the design. Thereafter, the clear and efficient communication of the technical design to the contractor is of equal importance. Shape Architecture is a Chartered RIBA Practice specialising in the design and construction of London basement extensions. Building a basement in London requires an experienced design and construction team. We bring a wealth of experience in the technical design of basements alongside excellent established working relationships with structural engineers and specialist basement contractors.

    As basement specialists, London offers the greatest opportunity to undertake basement projects and it is across numerous London boroughs that we undertake basement extensions.

    Our basements in London cover a wide number of locations, varying from cul-de-sacs to mews properties. They also vary in type from single storey to double to ones set below existing lower ground floors to ones entirely below gardens.

    As London basement specialists we recognise the concerns that clients may have in respect of undertaking such a process. Through the breadth of our experience and our clear communication we are able to answer all our potential clients’ questions.

    London Basement Extensions: Basement Tanking

    At the outset of a basement project the question ‘How do I tank a basement’ is often asked. At Shape Architecture as basement architects we retain a library of tried and tested Basement tanking details. These have been developed with basement tanking companies. When tanking a basement it is the application of standard details that is vitally important.

    London Basement Extensions: Structural Design

    When building a basement the structural design of the basement is vitally important. Digging out a basement requires attention to be paid to both the permanent structural design and the design and working methodology for the temporary works. The Basement wall and basement floor is typically a reinforced concrete wall with basement tanking and thermal lining applied.

    London Basement Extensions: Ventilation

    The Basement lightwell is the key design element that provides natural ventilation to a basement extension. As such it is a key design feature that offers much potential. It addresses issues of circulation and views between the interior and the garden beyond and also provides a key source of daylight alongside providing a physical amenity. Equally the use of a simple palette of high quality robust materials, such as a glass bridge provide valuable points of visual interest.
