Permitted Development Question - rear/side extension

[tp1]

Hi all

 

Apologies for another newbie question.

 

I am looking to extend out the back and side and am under the impression that a wrap-around extension does not fall under Permitted Development. 

 

If I was to extend "separately" out the side and out the back would this be ok (under PD) and would there be much difference in price given its the same size? Neither direction is going beyond 3m from house or should cause any other PD issues) 

 

Many thanks in advance

 

 

Pictures might help:

1. Current house footprint (including old out building to be demolished)

 

2. Potential wrap-around extension

3. Potential "separate" extensions

Some wrap around extensions can be carried out via PD providing they meet the PD criteria for both side and rear extensions, so they’re not completely ruled out.

 

Number 2 would require formal Planning and number 3 would normally be considered PD. That is assuming you are talking about single storey extensions? If so, then if number 2 is your preferred option, what’s stopping you from going down the formal Planning route?

I assume you are saying this because the side extension seems to be slightly larger than the previous footprint? Otherwise it would just be replacing existing to the side and only extending behind existing to the rear. So falls under PD?

No 3 would need formal PP for the side extension. Rear could be done under PD. 
 

Of course this is just my opinion... and could be complete tripe.

@Gav_P I think you need to read up on the PD rules ?

Thanks for the replies.

 

At this stage anything is doable - will be speaking to a builder at the weekend so will have more of an idea.

Around here it would be time, cost and aggravation.

I think a lot depends on if they consider the outbuilding to be part of the original house. Was the outbuioding constructed before 1948?. The original building is defined as...

If before 1948 then option 3 might need planning because you are extending forward of the original front elevation. Eg the outbuilding is not an outbuilding and you are extending it forwards.

Your quite right.. I was talking complete rubbish.  No 3 is obviously achievable by PD. 
 

But why would no 2 need PP? Because the side extension projects beyond the rear of the property?

Does that matter? The side extension can go as far forward as the building line (front of the house).

But there isn't anything stopping the OP from removing the "outbuilding" (although an outbuilding is usually a separate/detached structure) and then building a single storey side extension the full length of the original dwelling.

No but because the extensions would join together meaning the PD rules for side extensions would not be met, i.e. more than half the width of the original house.

I believe if built before 1948 the front of the outbuilding would also be considered the front of the original house. See top of page 15 in the technical guide.

 

and the definition of original...

So if built prior to 1948 it doesn't matter if the outbuilding was an extension its considered part of the original building.
