Might be a silly question, but i've had some designs done for moving a wall outwards on the rear extension and wall to be removed internally for a garage conversion. Sent the plans to a structural engineer and he has quoted but said he can work from the drawings/designs and doesnt need to visit the premises. Does this sound right? How would he know what foundations there are, is a padstone needed, current beam in place etc? As I say might be a silly question, but any advice appreciated.
