One Sherwood Street

This high-profile development project will deliver a new seven-storey mixed-use building with two basement levels, comprising of approximately 111,000 sq. ft of commercial office space, 30,000 sq. ft of retail space and seven new residential units, directly behind the piccadilly lights at Piccadilly Circus.

D4S were appointed by Wates to develop a modular strategy, with the intent to deliver RIBA Stage 4+ and 5 structural design including steel to steel connections and cold formed elements. The scope consisted of appraising the proposed featured architectural roof and current primary frame, to adopt an off-site approach for the scheme, which resulted in 80% of the roof structure being manufactured offsite.

Following on from this our detailing division delivered a complete fabrication package to a standard Severfield internal delivery, this enabled a smoother co-ordination between the workshop, ourselves and the client saving on unnecessary administration costs.

This included the following:

– Standardising part prefixes and material in the model to the fabricator preference helping to reduce material wastage.

– Following the fabricators internal connection design preferences and weld procedures

The benefits of a modularised system in central London included reducing the construction programme by an estimated 16 weeks, D4S designing the lifting strategy to limit the number of crane lifts, reducing the requirements of temporary works, reducing the carbon footprint, improving the health and safety conditions related to the construction operations and expediting the construction programme, with consequent significant additional value brought to the project.
