Fire regs in a 3 storey house?

Recommended Posts

Just wondered if anyone knows based on our plans (3 storeys from the front, 2 storeys at the back and side) whether the staircase will now not conform to building regs with it opening out into the kitchen?

Also the windows at the side and rear second floor are floor to ceiling with no openings.

 

Is there any way around this if it doesn't conform?

 

Cheers

The rules change when you go from two floors to three floors. They require the escape route from upper floors to be protected from fire for 30min. So I'm afraid open plan arrangements on the entry level are a problem in houses with more than one floor above (you have two floors above). A fire in your kitchen could quickly block your exit otherwise.  

 

I think it might be allowed if you install a sprinkler system but I'm not sure if this is an expressly permitted solution in the regulations or if its at the discretion of the Building Control Officer.

An additional external staircase might also be an option?

I posted a couple of days ago regarding our friends nearing completion of there 5-7 bed home 

Although it looks like a 7 bed Without drastic alteration It will always be a five bed

For the above reasons

Thankyou

 

If we didn't use the attic do you think we would still need escape routes or fire suppression as it would then be a normal 2 storey house from the rear but still 3 storeys at the front if you include the garage?

I think you should check with Building Control. I doubt they would believe you if you just said  you weren't going to use the top floor. If it didn't exist it might be ok but that seems like a shame to loose what you want for the cost of a sprinkler/mist system.

 

I've got a feeling Wales have made sprinkler systems mandatory in all houses - or was that just a proposal?

 

Edit: looks like they became mandatory for all new houses and flat in Wales from 2016.

I agree, i'm going to speak with building control next week and see whay they come back with, definitely the best option I think.

 

Cheers for the help!
