Carpentry & Joinery Question

Can stairs over 42 degrees pitch ever comply with building regs?

I have a 3 bed semi, and wish to replace my staircase whilst having a fairly substantial renovation undertaken

PS - I will have to supply a building notice as I'm having a couple of loadbearing walls removed that need signing off by the council anyway.

The problem I have at the moment is that the staircase starts about 1m from the front door (and goes straight up in front of you) and this does not leave much space to walk past it into the lounge.

I therfore wish to replace this (42 degree pitch) staircase with a steeper version (that by rights would not comply with building regulations) to give me more room when I walk in my front door - both for walking around and moving furniture in and out etc.

Can I have a steeper staircase beyond the 'maximum allowed pitch' and still comply with building regs

i.e. are they set in stone or can common sense play a part?

Any help would be appreciated if you've had a similar situation

Your not going to like this But yes common sense can play a part and in the eyes of building regs they would rather you struggled to get around , moving furniture ect then a potential accident on a steep stairs . Ive heard of them making people take them out when they have tried to pinch a little angle and make them steeper ( this is very rarely at the manufacturers cost as they should tell you its over the 42 deg . this is not to say you can not get away with 42.5 or even 43 as . just be careful . Just one thought ! if its a new stairs and you can redesign it slightly to maybe have a turn or a bull nosed step that only takes up floor space ( newel starts one step up ). Then do this

I'm afraid you wont be able to increase on this pitch as you are already at the allowance for domestic staircase. Whether it would be possible to change the overall layout of the staircase...for example introducing winders or a quarter landing area. Difficult to say without actually having seen the property and the layout within.
Sorry to be the bearer of bad news.

In a private house the maximum stair pitch is 42 degrees. It is outlined in Part K of the building regs.

Hope this helps
