restored
Space House is one of London's best known brutalist buildings: a circular concrete tower on Kingsway, designed by Richard Seifert in the 1960s and now Grade II-listed. Recently restored with restraint, it remains bold, sculptural and distinctive.
HERITAGE PRESERVED
Completed in 1968, Space House stands as one of London’s most significant examples of post-war Modernist architecture. Designed by George Marsh of Richard Seifert & Partners, its distinctive cylindrical tower and adjoining office block express a confident structural language, characterised by bold geometry, innovative engineering and abundant natural light.
A sustainability masterclass
This retained structure has been enhanced to deliver a highly efficient, future-ready workplace that meets leading environmental standards, combining low-impact development with long-term operational performance.
