New external steps to back door and building regs

[symbiosis]

Hi all - hope this is in the right forum section

 

As part of my recent loft conversion, the back door was moved and required new steps to be built leading to it as part of the BC sign off requirements. 

 

The builder who provided them unfortunately did so with varying rise heights

 

According to my BC officer, they need to follow part K of the building regs and therefore need to be uniform in size. 

 

My builder said he can alter them but (due to a very steep drop at that point) it would require an additional step that would only be half the rise of the others, will that be OK?

 

The other issue is that the steps lead to a platform and are on both sides, the other side being flat - so the steps on that side of the platform have a far smaller rise than the other side, is that OK or do both sets of steps have to be the same?

 

Any advice gratefully recieved

Two stairs leading to one landing can have different rise and going, but any stair must have equal rises in that run. What is the ground at the bottom? Can this be graded to sort the bottom step height.

And don't forget above a certain height handrails will also be needed.

Its a concrete slab at the bottom that slopes down, could he excavate that to make the last step the same rise?

 

PS, is there a tolerance on the rise as they are bricks with Indian Sandstone on top so they wont be exactly the same

 

Thanks

Yes, a bit of ground works would put the bottom step “in tolerance” they don’t need to be exactly the same but close! An obvious different step is a red flag.
