Not sure if conservatory would be permitted development- L shaped house

[FreyaV]

Hi,
I realised I posted this in the wrong forum earlier- I apologise to anyone who’s ended up reading this twice.

I wonder if anyone with knowledge of permitted development could offer some advice? I have recently bought a house and was hoping to build what I thought was a simple conservatory - I thought it would easily fall within PD but now I'm not so sure.

The house is detached and has no current extensions. I assumed that it would be fine because

1. It's less than half the width of the house - but I assumed this would be the whole house (dimension A), not the smaller dimensions B or C.
2. It would be between 4-5 metres (preferably 5 but with having to do the neighbour consultation thing!) deep but this would only make it approx 1m deeper than the 'furthest' back wall of the original house.

Now I'm uncertain as to which side/back elevations the rules refer to.

Just to note, the garden is large enough that the whole property including outbuildings will be much less than 50% of the plot.

Thank you so much in advance to anyone that can clarify these rules for me. I honestly though that since I was doing little more than making the house infilled into a normal rectangle and thus not affect neighbours' light etc, that it would be fine. Note, neighbours both sides are set slightly further back than mine so it would not extend further back than their properties. I don't think this is relevant but I'm just explaining that it wouldn't block their light etc.

As a side note, I’m realising that conservatories can be quite unpopular due to always being too hot or too cold - I’m trying to find a ‘cheap’ way to add a room area in the corner of the house because the large extended rear part is on the south side and therefore blocks the light coming into the smaller left side of the house. If anyone has any suggestions or alternative ideas I’d be really appreciative

Thanks.

At present 4m is the limit without going down the neighbour consultation route, but there are proposals to increase this to 5m for detached houses.
Might be worth waiting to see if/when this proposal comes in. A consultation (now closed) was put out in February so we don't know how the new government will deal with it. The Town & Country Planning Assoc. has of course objected, as is their custom, as they want to keep local authority planners in work.
(The rear wall will be taken as the wall marked 'C', not the outermost rear wall).

Thank you very much for this information, I really appreciate your help. I’ll have a rethink as I don’t want the whole neighbour consultation thing as I don’t want to aggravate the new neighbours! Just to check, would it make a difference if the conservatory wrapped around by a couple of metres onto the outermost rear wall?- would it then be measured from there? I’m guessing they’re more than used to this basic type of sneakiness and it would be a hard no, but just thought I’d check? Thanks again so much for taking the time to reply

If you wrap it round the back of the rearmost wall, it would need planning permission as presumably it would be more than half the width of the house?

Yes I hadn’t thought of that! I could only go about 1m round the back wall before it became half the width of the house (the left side of house is narrower) - thanks for pointing it out

I don't really understand why people are so keen to try and avoid planning permission.

You can apply yourself with a biro diagram and hand-written filled in form. You don't need an architect. You can do it all through the govt's website if you like, you get guided through the process. It takes no more skill than what you've already shown to create this thread.

Start by deciding what you want to build, THEN decide whether it does or doesn't need PP. If it does then apply, let them know that if they refuse then you'll do something similar with PD anyway. They'll probably say yes, and you'll end up with something you actually want.
