Designed to provide 30,000 sq m of floor space, at the time of construction this six-storey steel-composite structure was the largest speculative office development to be undertaken in London's West End in a decade.
Six of our departments worked with the architect Squire and Partners to develop the design, necessitating rigorous project co-ordination. The results speak for themselves: the building was delivered 15% below budget and two months in advance of the original programme.
Site challenges included the close proximity of London Underground tunnels and re-use of existing pile foundations, both of which required detailed analysis and strategy.
We used 15m spans to provide the necessary column-free space for a fully flexible, open plan interior. The steel and composite concrete deck floors are supported by cellular beams for services integration.
Our progressive approach to process as well as product helped in the construction of a speculative office development that exceeds best practice in many aspects of performance.
Achieving BREEAM Very Good was part of the brief for the six storey building, which provides 30,000 sq m of highly flexible working space. Our bespoke 3D modelling system informed the work of a tightly co-ordinated project team — we ensured that specialist subcontractors co-located with our services engineers from an early stage of design. Standardized components were designed with accuracy and prefabricated off-site, as was all significant plant, which arrived for installation fully wired and tested. The results speak for themselves: the building was delivered 15% below budget and two months in advance of the original programme.
Extensive efficiency measures include adiabatic coolers for free winter and mid-season cooling, variable-speed drives on all pumps and fans and the use of high-efficiency boilers and low energy luminaires. Overall, the carbon footprint of Belgrave House is only two thirds that of a conventional building of its size.
