Abstract

Decision letter detailing the determination of compliance with requirement B1. It relates to proposed erection of two-storey side and rear extension, a single storey rear extension and a loft conversion with a rear dormer. The scheme includes the formation of an entirely new protected stair rising through the three levels. The stair is protected by a fire resisting enclosure with a single self-closing fire door at each level. These doors lead to a landing or lobby area which provides access to the rooms via standard (not fire-resisting) doors. At ground floor level the stair has a second door which allows for direct exit to a side street.
