Hi to all who read. this is my first post here and hope to glean some knowledge or some advice.
I am here helping a freind who as just purchased the small 3 storey terraced house that as basically been a fish and chip shop with living accomodation above.
Planning permission as been granted for turning the (downstairs) from commercial to residential. Building control officer as advised on a few pointers these being
1, The need for a 1/2 hr fire protected corridor from the bottom of the stairs to the extenal door ( no probs with that)
2, The doors leading onto the landings and doors downstairs leading into the 1/2 hr fire zone need to be 1/2 hr fire rated ( Understood no probs there)
3, The extenal walls on the ground floor ( commercial but now residential) will need to be insulated ( No prob there but uncertain as to what this should be 50mm celotex 100mm celotex, insulated plasterboad?? does it need a Uvalue calculation??)
4,Linked Heat and smoke detection on each floor landing + kitchen ( no problem there)
5, Soundproofing to neighbour walls ( this seems not right as the wall are solid brickwork and plastered)
6, The property as a cellar and so needs insulation to the cellar ceiling ( I think the owner wants to do this but not sure if this would form part of regulation)
So basically just asking for any discussion regarding the above, the premises as a shop front window ( not full size of elevation) that forms part of a listing as in a listed building, this cannot be changed for a modern double glazed, BC as not mentioned this window, would it need to be dealt with or could it just stay as it is.
Thanks to anybody who wishes to help and advise.
