Delivering Basement Construction Across London for 25+ Years

Our mission is to deliver safe, dependable basements in complex London sites, combining practical expertise with methodical project management

Space Excavation is a London-based contractor specialising in the construction phase of basement projects. Trusted by building contractors, developers, and homeowners ready to commence construction, we provide technically disciplined, structured, and reliable services.

Once planning permission, structural calculations, and approved drawings are in place, we undertake structural excavation, reinforced concrete works, waterproofing, and groundworks. Every project is delivered safely, accurately, and on programme, even in London’s most constrained sites.

Our Team and Leadership

Founded by Greg, a site manager with over 25 years’ experience in complex basement and structural projects across London, Space Excavation was established to combine technical expertise with practical site leadership. Greg’s vision was to build a team capable of delivering basement projects with precision, discipline, and reliability.

Our team includes experienced site managers, Temporary Works Supervisors, reinforced concrete operatives, and specialist groundworkers, all trained to manage structurally sensitive projects in line with approved drawings and engineering specifications. From excavation sequencing and load transfer to underpinning and waterproofing, every element is carefully coordinated to ensure accuracy, compliance, and safe execution.

Built on practical leadership, technical rigour, and methodical delivery, Space Excavation consistently completes complex London basement projects safely, efficiently, and reliably.
