I have recently moved into a new house with the intention of launching into some renovation work immediately (loft conversion and two storey side return extension). I've begun discussions with an architect and he has advised that I can expect the following costs. That puts me at a cool £11.2k before I've have even started a discussion with a builder. Is this bonkers or is he right?
