Does anyone know an estimate of having a house built to be exact 2800 ft sqared? We would like to own 4 bedrooms on main floor, a small organization, a dining room, living room, and kitchen (all 3 open), a bathroom and a half hip bath in master bedroom. A full finished underground room with a small kitchen, furnace room, laundry room, storage room, bathroom, and small bedroom. All the rest is undo. Any estimates would be great. Want to get some opinion before we shift to a contractor.
