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.
