Glenn Howells Architects’ Gloucester Gateway motorway service station on the M5 continues to draw in plaudits as well as punters, winning the RIBA’s 2016 Client of the Year Award. Trying to be as sustainable as a services can be, all that locally sourced produce is tucked behind Technal’s MX curtain walling fitted by Elite Aluminum Systems. The high performance glass has neutral solar control to give clear sight throughout, but its two leaves of 10mm glass offer the kind of acoustic performance you need to repel the sound of gas guzzling cars.
