Have a 1950's 1300 sq ft 3b/2b house on a raised foundation and want to enlarge it to a 4b/3b house.  Contractors have come and given us ideas on where to add the additional room but the flow doesn't feel right.  I think we need an architect to help us.  Looking for referrals and any pro tips if you have added a room before.  Also how much should the architect service cost?
