The six-bedroom home has been built on the site of the former Grouse and Claret pub on Little Chester Street, SW1 by luxury developer Finchatton.
The house includes a basement swimming pool with hot tub, sauna and changing facilities, bespoke joinery and interior stone work and a sophisticated building management syste.
ISG is now on site starting a 48-week programme that will complete in July 2012, enabling the new owners to move into their home in time for the 2012 Olympics.
Planning, demolition and erection of the concrete frame had already been coordinated by the developer, leaving ISG with a remit to complete the external envelope, cladding the façade with brick and limestone and installing period sash windows and a slate roof.
The fully fitted bathrooms will feature integrated stone work and anti-mist televisions, while the living areas will be finished with hard wood floors and the BMS will co-ordinate, lighting, A/V, heating and blind controls throughout the house.
Peter Kilby, managing director of ISG’s special projects division, said: “Finchatton creates exceptional homes in desirable locations and the Little Chester Street Development will be a very special house indeed.
“Delivering the complexity and quality of finish required in a prestige home of this kind requires complete attention to detail, specialist skills and experience of addressing the technical challenges of such a high specification on a severely restricted site.”
