Basement Construction

Basement construction in Central London requires specialist knowledge, careful planning, and a deep understanding of historic buildings. Our team has extensive experience delivering high-quality basement projects beneath some of London’s most prestigious properties, including listed buildings. Our technical capability includes complex excavation in restricted access sites, groundwater management, structural waterproofing systems, and integration of new reinforced concrete basement structures beneath existing foundations.


Our approach incorporates detailed structural assessment, temporary works design, and carefully sequenced underpinning to safely transfer and support existing loads during excavation. Close coordination with structural engineers ensures that ground conditions, load paths, and neighbouring structures are fully considered throughout the process. Whether expanding a family home, adding leisure facilities, or creating functional storage areas, our basement construction solutions are designed to maximise space while preserving the historic value of the building above.
