Shell and core scheme to create new office accommodation for The Office Group secured as a Pre-let Tenant in the former BBC office/workshop building on Great Portland Street.

Works involve the removal of the existing lightwell and infill to create a new rationalised central core plus the construction of 2 additional floors.

A complicated enabling works/demolition contract was carried out which included the replacement of all existing steel columns and associated temporary works. The decision was made to split the works into two contracts to mitigate the programme delay caused by the need to go back to planning to change the core arrangement to suit the tenant’s requirements.
