The project at Westbourne Grove Mews involves the demolition of a warehouse currently occupying the site, while retaining party walls at both sides and the rear of the property. ISG will then build two three-bedroom homes, with two-storey basement accommodation, alongside 2,131 sq ft of high specification office accommodation. The design of the two-storey building will be in traditional London brick, with aluminium windows and a pitched, slate roof.
Scheduled for completion in October 2014, the programme requires extensive excavation for the two-storey basement structure, with piling works at the front of the property and underpinning to the three party walls. To reduce the overall construction programme, ISG will employ ‘top down’ construction, putting in the ground floor slab first, then building above and excavating below ground simultaneously. Added complications include no on-site storage facilities and the requirement to provide full access for both business and residential neighbours within the tightly confined location.
Once completed, the two luxury homes will each have a swimming pool, media room and gym within the basement. The specification also includes a double car stacker system in the basement to provide off-street parking.
ISG’s Stuart Deverill, managing director for London, said: “Deploying a top down construction methodology provides our client with the most efficient delivery solution, given the complexities and logistically challenging nature of the Westbourne Grove Mews site. The scheme is set to prove an excellent example of this seldom-used construction technique and further highlights the scope and scale of ISG’s knowledge and expertise in the delivery of individual, exclusive homes that meet exacting design and quality standards.”
