Space House
One of Richard Seifert’s creations, this beautiful grade II listed building is well known for its innovative architecture and striking grid-like, pre-cast concrete façade. Situated on Kingsway, the building has been thoughtfully restored to its former glory and now brings renewed vibrancy to the area through the addition of flexible retail and event spaces.

Employed by Seaforth Land in the early design stages prior to the planning process, we were engaged to provide an optimisation strategy for the façade package.
Our clients vision to sensitively refurbish the building in a way that was sympathetic to the heritage status, whilst also upgrading the performance of the building envelope, meant close collaboration with the architect, Squire and Partners.
To assist the client in maximising the return on the building, a cost plan and price point were worked up for the façade, ensuring that as the design evolved and progressed, they stayed fully abreast on any commercial implications. This gave them certainty of both cost and design at each stage of the process, from feasibility through to construction.
Following a detailed review of the proposed design, a modular window design was pursued that was sympathetic with the listed status of the building and worked well with the existing grid-like, pre-cast structure. These were developed as full height storey modules with a unique stainless steel integral mesh incorporated into the lower zone. This maximises natural light into the building but also obscures vision from the street level. The modules were also designed with the ability to include opening vents enabling a desire for natural ventilation to be met. Part of the early design process was to create a series of full size mock-up windows that were installed in the actual application to ensure all aspects were suitably covered.
At roof level, two additional floors were constructed to form a new terrace level wrapping around the perimeter of the tower. These feature curtain walling that complements the building’s aesthetic while offering sweeping views across London.
The retail spaces and main entrance to the commercial office area had an aspiration to be large format frameless glass that sat behind the existing pre-cast columns. To achieve this finish, a bespoke design of stainless steel framing was used that enabled this visual intent and also meant that automatic doors to the retail spaces could be fitted in seamlessly. At the main office entrance, a large stone clad canopy is also included which completes the stunning approach to the tower.
The opportunity to work on this stunning landmark building is exciting, and it has been a pleasure to work alongside both Seaforth Land and Squire and Partners to optimise the scheme and turn the vision into reality. Space House now stands as a world-class office destination—offering standout design, prime location, and market-leading space in the heart of Central London.
