A. Yes there are, generally fire regulations.

Mains connected smoke detection with battery back-up is mandatory in all new conversions and extensions.

Normally one detector to each hallway and landing is required and they must be interlinked.

Below is guidance on what needs to be undertaken for building regulation compliance to each property type.


Bungalow building regulations

When converting an existing bungalow the new staircase can generally be sited anywhere on the ground floor. Each new habitable room in the loft conversion will have to fitted with a window for escape purposes which must have an unobstructed clear openable area of 0.33 square metres, this is best achieved with a window opening a minimum of 450mm wide by 750mm high and can be either a window within a dormer, external wall or a Velux roof window. The bottom (cill) of the escape window must not be higher than 1100mm above the floor.


House building regulations

When converting say a standard 2-storey house into 3 storeys careful consideration must be given to form a protected route out from the loft rooms to a final exit at ground floor. The upper storeys must be served by a fire protected stairway (protected at all levels) which either at ground floor:

a. discharges to a hall served by an external door, or
b. there must be at least two separate escape routes available to an external door – separated by fire resistant construction and fire doors.


If you have an existing open plan staircase please see notes below.

The protected stair enclosure should be enclosed in a minimum 30-minute fire resistant structure to protect the escape route for the occupants to make a safe escape. All doors (new and existing) opening onto the protected stair route are to be fire resistant. This means your existing doors will probably have to be changed to fire doors. One concession is that there is no need to fit self-closing devices to fire doors anymore apart from a door to an integral garage. You must ensure that the new loft access/stairwell is an extension of the existing to avoid the creation of inner rooms i.e. where escape can only be made by passing through another room (this situation is not acceptable).

A lobby and fire door at the bottom of the stairs off your existing landing is acceptable, as long as there is one new loft room only.


Q. What if I have an open-plan arrangement in my house i.e. stairs are open to the main living areas and are not enclosed by a traditional hallway leading to a final exit?

A. Where the existing house is open-plan, it will be necessary to provide a new 30-minute fire resistant partition with fire doors to enclose and extend the escape route to a final exit as indicated in the diagram below.

There is no longer a requirement for escape windows in any new loft rooms of houses.
