North Circular Road site 6
The North Circular Road Site 6 project is part of a larger regeneration of the area bordering the North Circular Road in Enfield, North London. Site 6 consists of 95 mixed tenure residential units split in to four blocks varying between 3 and 5 storeys in height. The site was heavily contaminated and had a significant fall in level across the site but through optimisation of the site levels it was possible to minimise the amount of material required to be taken off site and create significant cost savings. The four residential blocks were formed as reinforced concrete frames with localised transfer slabs to achieve the large spans above the access roads which pass beneath several of the blocks. The use of integrated finite element modelling and Revit allowed for a lean efficient design and aided collaboration within the design team.
