London based real estate developer, Seaforth, has signed a contract with BAM Construction to deliver the £110m refurbishment of Space House, a landmark Grade II listed building set across two interconnected buildings in Covent Garden.  

Designed by Richard Seifert & Partners, Space House was completed in 1968 and is well known for its innovative architecture and brutalist concrete cruciform façade. The building was first occupied by the Civil Aviation Authority and will now be brought back to life with an extensive redevelopment to deliver a highly sustainable, smart building designed to BREEAM Outstanding.  

Squire and Partners has led the redesign of the buildings which will include the construction of two new floors of office accommodation on top of the existing 15 storey tower, a top floor extension to the interconnected eight storey block and reconfiguration of the internal cores and basement levels.  

Chris Railston-Brown, Development Director, Seaforth, said:  “We are delighted to announce the appointment of BAM Construction to deliver Space House. BAM Construction and the consultant team have worked tirelessly to ensure the reinvented Space House will turn from vision to reality.  

“This is a great step forward for the Central London office market and reinforces our commitment to delivering exciting new spaces and opportunities. Space House will offer market leading and sustainable office space in Central London, and we are looking forward to working with the BAM Construction team to bring Space House to life.” 

The project will extensively refurbish both buildings to create 255,000sqft of market leading Grade A office space. Space House will offer extensive public realm improvements and the replacement of existing car parking spaces with London’s highest-provisioned cycle centre. New public, retail and event spaces will also be created for the basement and ground floor levels. 

Enabling works are underway and main construction work is scheduled to begin in April 2022, with a planned completion for Q3 2023.  


”This is the first time we have worked with Seaforth and we are delighted to have been chosen to deliver the exciting refurbishment of this iconic building. We will ensure that quality and sustainability is at the heart of this scheme that will establish Space House as the first-Grade II Listed refurbishments to be awarded a BREEAM Outstanding certification. 

“As with all our projects, and alongside Seaforth, we will look to ensure that this landmark scheme delivers wider social value to the local area and we are working with the surrounding community to identify opportunities to support local initiatives and programmes.”
