G A Design Services was established in 2002 by our managing director Gavin Anderson. We are a family run business. Gavin has over 25 years experience in the construction industry. We provide  vital CAD design services to the architectural glazing industry covering commercial and residential projects and we offer comprehensive and bespoke CAD designs to our clients. 

We primarily specialise in architectural glazing systems and curtain wall design however we can offer full building envelope detailing including structural steel work. 

All of the photograph's displayed on our website are of projects we have worked on.
