Tiny Houses - Building regulations for stairs
I've just stumbled across the small house movement and I quite like what they're doing. It made me wonder about planning regulations over
here though. Many of them have sleeping spaces on mezzanines - basically the loft space. To get up to them they use what look like over sized
ladders that are fixed into place. They're the width of stairs but at 70° like a ladder. Would you be allowed to do this in the UK or do you
have to have "proper" stairs?

I'd never heard of the 'movement' until you mentioned it, think this look great!

Standard stairs should have going (length of tread) of no less than 220 and a rise (height) of no more than 220, BUT also must be at a max pitch of 42
degrees.
There is one option that can only be used in certain locations - and il have to cut and paste the regs:
Alternating Tread stairs
1.22 This type of stair is one of a number of stair types designed to save space. The general pattern of steps has alternate handed steps with part
of the tread cut away; the user relies on familiarity and regular use for reasonable safety (see diagram 9).
1.23 Alternating tread stairs should only be installed in one or more straight flights for a loft conversion and then only when there is not enough
space to accommodate a stair satisfying paragraphs 1.1 to 1.17 above. It should only be used for access to one habitable room, together if desired
with a bathroom and/or WC. This WC must not be the only WC in the dwelling.
1.24 Steps should be uniform with parallel nosings. The stair should have handrails on both sides and the treads should have slip resistant
surfaces. The tread sizes over the wider part of the step should be in line with dimensions shown in Table 1 with a maximum rise of 220mm and a
minimum going of 220mm. The provisions stated in paragraph 1.9 will apply.

That's great, thanks. This isn't the picture I was thinking of (can't find it now) but illustrates what is quite common.

The only way to get away with that would be for it not to be classified under building regulations, which I guess would need to be a) a mobile home,
or b) a houseboat.
That all I can think of anyway.

Spiral? you'd struggle a bit with the previously mentioned options imh(professional)o - I can think of a couple of ways to get them through but
not sure it would be worth the hassle

The Uk has some of the smallest housing sizes anyway, we dont need any smaller houses! Better use of land and better design is all we need!
