The matter before the Authority was expressed as being whether, in order to comply with paragraph 4.6 of Approved Document C3/AS1, walls which divide a building into unit titles must extend above the roof to form a parapet when the fire hazard category of the building is 3 or greater and the roof has no fire resistance rating.
A sketch accompanying the application showed a "typical site plan" of a building with a flat roof subdivided into two unit titles. An external wall of the building just inside the title boundary of the site was shown as being as extending above the roof to form a parapet for the protection of an adjacent building on the other side of the site boundary. The internal fire-rated wall that separated the unit titles was shown as extending to the under side of the roof cladding. Although not noted on the sketch, the roof presumably had no fire resistance rating.
