Building control require structural drawings so I need foundation and frame design, will supply basic drawings and information (it's 8m x 4m single height, well insulated foundation and timber frame, tiled roof With solar panels, approximately).
Been quoted £500+v by a well known reputable structural engineering company who are familiar with insulated foundations and good detailing on cold bridging etc....
On the money or could do better?
