BPR were appointed by HBD to prepare proposals for Teal House, an existing three storey office building located in Cowley Business Park, Uxbridge. The brief was subsequently developed to include re-modelling of the existing internal core layout and construction of a new extension at the back of the building to increase the net lettable floor area from 22,000 sqft to 30,000 sqft, with the aim of attracting large corporations as lease holders. A new two-storey glass and zinc entrance lobby has been designed to enhance the dated appearance of the existing building and improve its marketability.
