Is building regulations approval needed for a loft conversion?
What improvements to an existing house may be necessary after converting loft?
Loft conversions and Smoke detectors.
Fire rated doors and loft conversions.
Houses with 3 stories including ones with loft conversions in London should have fire rated doors FD30 installed to bedrooms and living spaces. If existing doors in the house are not fire rated, they can be painted with intumescent paint to provide 30min fire resistance. Painted doors need to be good quality. If doors have panels, they should be made from solid wood minimum 10mm thick. Another alternative to replacing existing doors with FD30 doors would be installing smoke detectors in each bedroom and living space. Loft Conversion bedrooms should have fire doors installed.
