Re: Standard (minimum) width of stairs 13Jul 17, 2011 12:30 pm architect david, you are correct. i had a look this morning and couldnt find anything in there. the 750mm that i thought existed related to min landing length. i am used to looking at the BCA Class 2-9 and not 1-10. 2-9 more comprehensive on stairs as you pointed out with widths for egrees outlined HHCIB looks like you can make the choice here. from most comments made I think most people are in agreeance 900-1000mm min in width. Good luck with the reno. I agree with architect, when I was looking for this info I couldn't find any reference to width only risers and goings and of course ceiling height - which isn't under 'stairs'. I think there used to be a minimum width but got changed over time Also I think the reason is that for example if you are accessing a non habitable room like an attic then the width doesn't come into it because an attic ladder is only around 400mm wide. Habitable rooms have different specifications. We will be putting in stairs instead of an attic ladder but will only have 700mm (all enclosed) - this will be difficult for getting anything up there that is large but we plan to lift things in via a large dormer window or during the build, 900mm+ would be far better if you can Re: Standard (minimum) width of stairs 14Jul 17, 2011 3:03 pm As tricky as it might be... do you think that 900mm (potentially all enclosed) would be adequate for getting furniture up/down - not huge almighty pieces but say a standard sofa/beds/mattresses/bath etc? We might be able to lift stuff in prior to finishing off but in the long run, you need to be able to get things up/down the staircase if need be. So... anyway, would 900mm be ok do you think (and like I said, possibly fully enclosed, so no room to hang things over the side of ballustrades). HHCIB Re: Standard (minimum) width of stairs 15Jul 17, 2011 10:44 pm Ok, dont quote me but i think the minimum is 630mm. I will check tomorrow. Re: Standard (minimum) width of stairs 17Jul 19, 2011 9:28 am Thanks architect. Just about to reply. HHCIB Re: Standard (minimum) width of stairs 19Jul 20, 2011 3:30 pm Stair regs. Are mainly about tread/rise and pitch also min. Headroom off bulkhead. Twice the rise + going must fall between 550 - 700 mm. Keeps angle correct. I think around 42 degrees is optimal. Width is up to you, but consideration for furniture access is your main concern, 950 over stringers is pretty common I think. My land is 260m2 (10m x 26m) located in claymore NSW.
