![]() ![]() Loft conversions to two-storey houses invoke the same fire-protected route requirements, but they have some concessions. Homes with top floors above 7.5m require a second escape staircase or some added protection to compensate, such as a sprinkler system. Self-closers on these fire doors are no longer a requirement. The stairway enclosure throughout should be constructed to be fire resistant for at least 30 minutes, with FD20-rated fire doors (which are resistant for at least 20 minutes) to all habitable rooms along it. In new build three or four storey homes (with a top floor which does not 7.5m above ground level), a protected stairway must be created that is continuous to an external door at ground level. ![]() Fire Escape Routes in Three or Four-Storey Homesįor homes of three or more storeys where floors occur 4.5m or more above the outside ground level, egress windows are not an option for fire safety. The notable exceptions are kitchens, utility rooms, bathrooms and dressing rooms which as inner rooms do not require egress windows. This could mean having to replace windows, but it is usually possible to change standard scissor hinges for egress hinges on existing windows that do not open wide enough. Therefore, a fire in the access room means escape is necessary through an egress window or an alternative door route.īe wary of inadvertently creating inner rooms when extending or when creating open plan layouts on the ground floor by removing walls to hallways. ![]() Inner rooms occur when you have to pass through another (access) room to reach the hall, stairway or external door. You may also need ground floor egress windows to serve ‘inner’ rooms.
