5-7 Carnaby Street, Soho London
This project is a mixed use office and retail scheme which consists of a new double height roof extension and new Green Wall on Carnaby Street located in the heart of London’s Soho.

Stockley Park is an established business park near Heathrow, where The Bower at 4 Roundwood
Avenue has given the practice their first project with Exton Estates.
The existing building was ripe for refurbishment, and this became a complete transformation. Initially the thought was to retain as much structure as possible and change the whole layout to deliver a contemporary office environment; but to achieve this, the design evolved into extending the floor plates, relocating the
cores, creating a central atrium and replacing all the building services and the façade. This gives extensive flexibility, enabling anything from four separate tenancies per floor to a headquarters building for a single tenant.
Office space is created over three floors, served by four cores located around the light-filled atrium and reception space. The façade has been designed to balance daylight penetration and thermal efficiency and creates a striking visual appearance.
The MEP services solution uses all electric air source heat pumps as the base heating and cooling system with extensive energy efficiency and sustainable measures, delivering a BREEAM Excellent rating and A rated EPC. Features include 370m² of roof level PV panels, heat recovery, automatic lighting controls with daylight dimming plus energy management for tenant billing and demand control purposes.
