Hi guys, does anyone know how to stop the spread of fire so it complies with british standards between a proposed garage (independent and located on west side) and a proposed conservatory (attached to house located on the east side) that are 10 metres away from each other (east to west) but if you were to draw a notional line from the front of the garage to the front of the conservatory they would only be 500mm distance away from each other (north to south). Once again many thanks for all your help.
