liam O'doherty architects, very reasonable and he has a great knowledge in this area!
He will design a house that will be structural sound! Not like alot of architects who will desgn a house but will forget that blocks are made from concrete NOT rubber! It will look great on paper but hand the plans to a builder and he will change a fortune for circular walls, unusal roof designs etc.!
Did you ever think about getting a technician/draughtsman/engineer to draw the plans, probably half if not quarter the price, especially if ye are thinking about a relatively straight forward design!
