stairs - going/rise/gait

hey folks

I dont know if this is a question or an observation...

I am trying to design a stairs to gain access to an unused room (to use as an office) upstairs in my house (built 5 years). It needs to go up 7 or so steps on to a quarter turn landing and up another few steps to upper floor level.

while adhering to Technical guidance K directions: http://www.environ.ie/en/Legislation/DevelopmentandHousing/BuildingStandards/FileDownLoad,26938,en.pdf

I am finding sticking to 250mm min for the going restrictive. I need the going on the upper few stairs to be about 210mm. which is on the nose 42 degrees and within gait specs.

I had planned on like a 900mm by 900mm landing for the quarter turn but as I said my going is under limits.

does using a few "winder" steps give me more height in the same space? maybe that is worth looking at.

I really don't like winders in a staircase; however you may need to them to solve your problem.
Using winders you may gain 1,2 or even 3 rises dependent on how its set out. The trade off is the more winders/rises you have; the greater the risk of taking a tumble when climbing the stairs.

If possible set the turn at the bottom of the staircase; that way there is less of a distance to fall if someone does trip.

Google image staircase winders to head your head around the geometry.

thanks.

Is there somewhere in building regs documents that give specs for permitted winder dimensions?

It's in the same Part K document as per link above. Paragraph 1.1.6, referred to as 'tapered treads'.
