dnb Posted November 22, 2021 Share Posted November 22, 2021 Am I correct in thinking that a 3 storey single occupancy detached house requires 30 minutes fire protection for the escape route? There is only one way out of the top floor, but then multiple means of egress on the 1st and ground floors. My current plan should give 60 minutes for the walls but this is influenced by other requirements like sound insulation. Link to comment Share on other sites More sharing options...
Mr Punter Posted November 22, 2021 Share Posted November 22, 2021 I think they like a protected staircase as the main route, plus an escape window as an alternative. 30 mins is fine. Link to comment Share on other sites More sharing options...
dnb Posted November 22, 2021 Author Share Posted November 22, 2021 Yes. It is a protected staircase. Can't have an escape window on the top floor so I have gone with the multiple exit option and agreed it with my BCO. Thanks for confirming the 30 minute minimum - it makes life a bit easier elsewhere. Link to comment Share on other sites More sharing options...
