Permitted development question

[S1MMA]

Hi all, I'm considering buying a property to renovate so just getting my head around PD rules and regs. This will be in North London, and not in a conservation area.

I’m looking to buy a detached house, so understand that the maximum single story rear extention is currently 8m (subject to PD conditions) and after neighbor consultation, and 3m for a double story extension.

My question is, could you do an 8m single story rear ground extension, and also a 3m first floor rear extension? Basically combine both sections of the rules? Or can you only do one or the other?

I’ve not seen this scenario anywhere so interested to see if it’s possible?

Also if you are undertaking a rear extension, is there anything stopping you also doing a side extension and even roof extension at the same time, say a rear dormer?

Thanks!

There's a government guide on the net that explains what you can and can't do under PD, the illustrations are rather basic, but communicate well what you can and can't do under PD:
https://www.gov.uk/government/uploads/system/uploa...


You can't mix & match rear PD extensions; it's either upto 8M single story OR up to 3M two story. So you can't do your scenario. Also, if there's already a rear extension, be it approved under planning or PD, you'd need planning permission to add a second story.

You can do multiple PD extensions, so rear & side (provided of course they remain within the PD limits); what we did with our bungalow, both sides and one rear under PD.

Oh, and make sure the property you're thinking of buying hasn't had any of it's PD rights rescinded

Actually, you can, you know - I have.

The LPA simply asked that the drawings on the 'neighbour consultation' proposal (8m. ground floor extension) showed only that element of the work for them to assess. The two storey element was 'plain' PD, of couse, and required neither neighbour consultation nor the LPA's assent.

OP: feel free to contact me, if you want to see the above mentioned example.

That really surprises me, as the PD rules are quite clear as to mix and match not being allowable.

I would expect that if your situation was challenged it would fail.

Do you have a certificate of lawful development for both items ?

Interested in this one.

Which rules are you talking about, specifically? Is it the situation set out on page 22 of the technical Guide that you're worried about? Didn't apply in our case, as the single storey element and the two storey element weren't joined (which is the critical issue in the interpretation).

We didn't bother getting a CLD for the 2 storey element, but the legality of the strategy was agreed by both the case officer and my own Planning Director (a Chartered Planner with extensive LPA experience at a senior level).

Note, however, OP, that the relaxation for the increase limits currently only runs until end of May next year, and you must have completed the work by then. They've extended the relaxation once, but as far as I'm aware they haven't yet declared an intention to do so again, yet, so you shouldn't rely on it being there beyond next May.

just a note - don't confuse 'Permitted development' (a one-time exemption) and 'stuff that doesn't require planning in the first place'.
Most people do (including a local planning officer at my local council )

Ok, I had incorrectly assumed you were inferring you had the 2 linked together
