Having taken on a house in a conservation area, anything visible from
the road requires planning permission (and the local Stasi would be on
anyone who didn't like a ton of bricks given a chance). Going through
the requirements, the one outstanding item I need is a floor plan.
Not that I'm applying to change the layout at this stage, just cos
rules is rules.

I'm hoping that someone here has been through this recently and can
advise. I'm assuming that I don't need to have an architect, but
guessing that the plans should look approximately architectural. I
was thinking of trying to knock them up with Sketchup, but what level
of detail do I need to include and how accurate do all the components
have to be? For example, do all the wall thicknesses and door widths
have to be scaled accurately? I just want to hit the balance between
making it all too laborious and having the application sent back, so
any tips or experiences gratefully received.

There seems to be surprisingly little information publicly available
on any of this, although I might not have hit the magic combination
of words for Google.

Planning permission applications are in the public domain, which means you
should be able to log onto your local planning authority's website (or any
other) and view documents sent in, in support of applications.

If you do this you'll find the standard / level of detail / accuracy varies
enormously to the point you'll wonder why you worried!

Well having recently employed an architect to do my plans and submit a
planning application for a re-model, I can confirm that not only did he go
into inordinate detail, but much of it was wrong!!!! Didn't stop him
charging a hefty fee (£1400 iirc) but we did get the permission which is
what it was all about. Pure co-incidence that he used to work in the
planning department, and of course this didn't affect our initial choice of
selecting him G

Well - whatever works has to be the right way to do it, and a little
inside knowledge is always a benefit.

I've sort of given up on the 'pros' as nobody local seems to return
calls, emails etc. Given that the proposal is a no-brainer (famous
last words), I'm doing my own in the interests of speed, to get half a
chance of doing homework before the winter....though not spending
£1400 is a nice bonus!

No exp. of conservation stasi but I would just rough it out - sketchup to rounded 1dp dimnesions but forget wall thicknesses etc - just big thick lines & nice square geometry for outer walls and thinner ones for inner walls - 30 mins? if they wibble ask em for (written) chapter and verse on what you are sposed to do? (and what they will do with it?)

As long as it is straightforward I would think that you would be O.K. with
graph papaer and a soft pencil.
If you put in the measurements and note "do not scale off this drawing" then
as long as the planners can see clearly what you are doing you should be
fine.
Oh, and talk to your planners and ask them.
They are often very reasonable people :-)

Nope. It must be some while since you last submitted a planning permission
application. All drawings must include a scale bar

Nope. That might have been the case some while ago, but most LPA's no longer
offer 'face-to-face' pre-application consultation. Typically you are
required to write in and pay a fee.

Strange - I've just received planning permission and the architect's
drawings state in big letters "do not scale off this drawing" and do not
include a scale bar.

There is also a requirement for the planning department to have a Duty
Planner available to answer questions.
We have not been charged for talking to the planners, nor for the visits by
the planning officers to our house.
Even if there is some charge for "face to face" meetings in some areas you
can certainly ask questions by phone or email.

Which LPA are you referring to?

problem is you can't legally rely on anything you are told verbally - so it's Fing pointless for anything non-trivial. Even then IME the initial viewpoint of any particular officer starts with reasons why not rather than any hint of a "Yes" - called "jobs for the boys"...

Not true, my last employer lost a significant court case over an oral

I'm sure they are reasonable people. Unfortunately, the only
information I could get on the phone, which was just about the
process, turned out to be completely wrong, so there seems little
point in dealing with their frontline staff. I'm sure if I had
unlimited time to argue my way through to the people who know, I could
get plenty of good information....

Donno about the planning side but having decent scale drawings with
correct wall thickness's, door and window positions and sizes may
well be very useful later. Spend the time now measuring and drawing
and you won't have to do it again.

I drew up a three view on Corel draw in colour and got my pllanning
permisson with that.

Then I took THAT to an architect who turned it into Working dwarings.

I did have to ask him a few things first like, waht pitch angle I needed
for a thatched roof, and how far above ground level a DPC would be and
how high celings are generally.

Oh and I had to suss out a legal staircase and corridor widths for the
interiors, bur really planning is about visual impact on the community
and general size: its not about 'meeting building regulations' - that is
what you need detailed drawings for.

Good point Dave, and I have done the full works for just that reason.
It's a long slog though between that and a full set of detailed plans
and I'd rather just give them the minimum. Ironically, the
application is for roof work, so it's not easy to see what role the
floor plan will play in the decision.....

I reckon a hand drawn with rough dimensions should suffice. I've even seen approved planning apps done on a sketch basis with some "very" loose descriptions of what already exists....

I couldn't agree more - the less said, the less there is they can hold
you to. On the other hand, for a house that has had no permissions
under current systems (as nothing has been done that would require it)
someone with no scruples or respect for bureaucracy might even include
a few minor changes that hadn't actually happened yet, which they
could subsequently claim were 'already there when I bought it guv -
you can see it on the plans - I just refurbished it', especially if
they could be wriggled out of as drawing errors, should the need
arise....

Perhaps you really mean "minor changes" in which case I dare say they
would be fuzzy enough to get through much as genuine minor errors and
miscalculations seem to get through in the ordinary way. But there
have been one or two high-profile examples in this neck of the woods
where gross distortion[1] of the permission has resulted in the
offending structure being torn down again.

It really is a game, so I'd play my cards close to my chest if i were you, don;t give me any more than they can (legitimately/justifiably) can ask for, there is always a danger that it will come back and bite you on the arse later...

I couldn't agree more - the less said, the less there is they can hold
you to. *On the other hand, for a house that has had no permissions
under current systems (as nothing has been done that would require it)
someone with no scruples or respect for bureaucracy might even include
a few minor changes that hadn't actually happened yet, which they
could subsequently claim were 'already there when I bought it guv -
you can see it on the plans - I just refurbished it', especially if
they could be wriggled out of as drawing errors, should the need
arise....

Perhaps you really mean "minor changes" in which case I dare say they
would be fuzzy enough to get through much as genuine minor errors and
miscalculations seem to get through in the ordinary way. But there
have been one or two high-profile examples in this neck of the woods
where gross distortion[1] of the permission has resulted in the
offending structure being torn down again.

[1]Gor bimey guv, are those centimetres? I thought they was inches.

Indeed, it wouldn't be good to have an enforcement notice for
anything, although they do have to catch you first. Clearly anyone
could make the cm/inch mistake if they put their mind to it, although
a factor of 2.4 may well be easy to spot. If, on the other hand, the
plans (lodged in a completely different context) showed, for the sake
of argument, a conservatory that was 'mis-measured' by an even metre
in depth then it would hardly be surprising if it was replaced by one
of the mis measured size when it was re-built. If this happened to be
in an un-overlooked location, so nobody could see it anyway and the
final product tallied with the 'official' plans held for reference by
the LA, well, it's hard to see how any objection might arise. Not
that anyone would even think of doing such a thing deliberately, of
course.....
