We are considering having a double-storey extension to the rear of our house and some change of layout and would like an architect(s) to come and suggest different layouts that might work.
Do they charge to visit your house and make suggestions or only when they draw up plans or what? Also, I presume they know what can and can't be done in terms of permission/ building regs/ removal of walls, etc, or do I need a builder to come and look as well?
TIA
