Originally from Cheshire, Steve's fluent spoken French and knowledge of the complexities of the French planning system make him uniquely able to manage projects for eager builders of all nationalities.

Very impressed with ECSUS design from the start of our new build project near Morzine to the finish. Great attention to detail. Lots of help with decisions and produced an immaculate chalet with fantastic energy efficiency ratings. Highly recommend
