6 Broad Street Place is located within the heart of London, in the Finsbury area. City of London Corporation are looking for the building to be refurbished to maximise NIA, modernising to suit current commercial office needs and improving overall functionality, the moment of arrival experience and circulation through the building. Environmental performance for the structure is looking to updated and upgraded in order to improve efficiency and foster a more long-term sustainable solution.

The existing building is a seven storey, steel framed structure with a single storey basement that spans across the footprint of the site. This current structure was built in 2002, when it was rebuilt behind an existing grand stone façade dating from the early 20th century. The design was for offices in the upper floors and retail space on the ground and basement floors, with tenants being vacated in 2022.

Proposed structural interventions include a single storey rooftop extension providing additional office space with a terrace and communal garden on the new roof. Also, a new lightwell to infill to the rear of the structure has been designed, which was achieved by extending out the building floorplate at all levels. Additional interventions include moving the main lift core, relocation of the stability bracing, strengthening of the existing structure, alterations to the basement, a new substation, underground drainage design, a larger goods lift and a cranked steel roof.

Where the existing lightwell steelwork is to be removed and replaced, we have ensured our design solutions for the additional upper level and lightwell infill can utilise re-used steelwork from the existing lightwell structure that is being removed. The existing crane piled foundations has provided enough support for the new lightwell structure to be added to, without overloading of the neighbouring existing foundations. Local strengthening to existing beams, rather than full strengthening of the beam where not required, to save on steelwork.

There is a target for this building to achieve the BREEAM Excellent rating.
