I'm hopeing to insert a new floor above my stairwell, which will require a
new staircase.

Presently this is coming in at a steep 9 * 7.5" rises over a total 26"
horizontal, this is a little flexible but that isn't far off the lowest
gradient I can manage. What are the rules governing these measurements?

The space of the mezzanine itself fits in a lowered loft space, and will be
approx ~6' high at the apex going down to ~3' at the eaves.
Are there any regulations as to space requirements? Use is occasional
bedroom.

I was hopeing to put a velux in the roof, but am unsure how planning
permission may be affected by this, it can go on either aspect, but the
preferred one will overlook other properties and there is no way to get it
high enough to prevent this (6' max height of space). If it goes on the
other aspect, I just see next doors roof. I don't expect planning is
required other than for this reason, if at all. I think I can get a letter
from the Council saying "You don't need planning permission", if indeed I
don't.

The first thing you need to look at is the building regulations because
regardless of any planning permission requirement you will need approval
from the building control section of your local council. Before you do
anything else go and talk to them because it may save you a lot of wasted
time and money.

Yes my question was intended to encompass building regulations and thus
possibly save me even more time.

General knowledge of these regulations, input required.

Common sense, plenty of, not required.

That sounds more like a ladder than a staircase! To meet building regs
the maximum inclination of the stair should be 42 degrees. Max rise per
step of 220mm and minimum going per tread of 220mm. Note that you can't
have the max rise and min going in use at the same time.

Look at Part K. Note that the rules can be relaxed in some cases for
loft conversions.

Don't think there is a minimum height requirement for the room itself.
There is one for the headroom over a staircase though. (at least 1.9m in
the centre of the treads)

As long as you are not in a conservation area or own a listed building
then PP is highly unlikely to be required for a velux - even if facing
the highway.

All very well Mike but many are lacking this vital item! I still say go and
talk to them because there are all sorts of factors. Without a detailed
knowledge of your property it is not possible to give a detailed answer.

Consider using a spiral staircase. You haven't a hope in hell of getting
such a steep straight step approved.

What is the minimum permitted stair width for such things? I did
follow the link but got pretty lost!

A more specific link:

http://www.odpm.gov.uk/stellent/grou...reg_600500.pdf

Page 6 in the PDF is the start of the section on stairs, page 7 talks
about width requirements. The basic gist is there are no explicit width
requirements for a domestic stair as a result of this part of the regs.
However they may be if the stair is a means of escape, when the fire
regs might kick in, or, if the stair is providing access for disabled
people. In which case consult documents B for the former and M for the
latter.

There may be cases where a fixed ladder is acceptable... you would have
to ask the BCO though.

Failed - max of 42 degrees - i.e goings risers
See the K regs part 1 on the ODPM website

Again not legal. 2m is normal but for lofts 1m90 reducing to 1m80 at the
sides is the minimum.

If it is only 6' max height I don't think you can call it a bedroom
officially anyway. Not sure where I read that though.

Check your council's web site. Some requite permission for roof windows,
some don't.

Not when it's a bedroom. Look at alternating tread stairs provided your BCO
to allow them.

Not suprised. Alternatives, research, I will.

Thats a bit mean!

Don't care what it is called officially, it's really a mezzanine, I know an
estate agent couldn't call it a bedroom, though the 6' figure you recollect
is for horizonatal bed fitting and can't be under that for official bedroom
status.

mmm, not looking good though is it ;-(

Ang on, that makes the going on each step just 3" You'll be telling
us you've got 4' of headroom next!

I give up. These documents are as clear as a 10 acre mudfarm. I'm
thinking of a loft room with 2 exits: the stair and a roof opening
window.
