We are planning to add a small room at the back of the house to replace a rather odd conservatory that we inherited. The idea is to create a single-storey room that is really a glorified conservatory, ie opens onto the garden. Our neighbours have done this and we plan to match their design (with their blessing) so it blends in (older house), although our part of the house sticks out further - ie, it will be on a different line.
We have had an architect quote to design and create plans and take up to a planning submission (if required) and we wanted to just get a feel if his costs are reasonable - they are in four figures.
I know you haven't seen it etc etc but very roughly how much should we be looking at?
