The Solar Office (see Figure 10.1) is a new office building designed for Akeler plc on the 32ha Doxford International Business Park, located in Sunderland in the north-east of England. It is occupied by the leading ecommerce company domainnames.com. The brief for the building and its procurement followed the robust fast-track pattern that is now commonplace in speculative office development, a course already adopted and refined at Doxford. Where it breaks with convention is in its response to energy use and the environment.
