L Shape Dormer under permitted development?


Recommended Posts

Hi there,

 

I'm planning on having an L shape dormer loft conversion. It's a Victorian terrace house with an outrigger at the back which was built at the same time as the main house.

 

It will be just under the 40m3 so it falls in line with and meets all the criteria of permitted development. The architect has said he has experienced a number of councils refuse L shape dormers as they no longer see the back outrigger as part of the original house - even though it was built at the same time...!

 

Has anyone experienced an issue such as this? I'm in Elmbridge, Surrey and have made contact with the planning department but have been really unhelpful and won't say either way. 

 

Here's an article about one in Lewisham - https://www.theguardian.com/money/2019/aug/28/lambeth-council-permitted-development-rules

 

Thanks

 

MM

In the good old days you could ask a planning officer for his opinion. These days they want a fee. 

 

You can pay for "Pre Application advice" but the only way to be sure 100% certain it comes under Permitted Development is to apply for a certificate of lawfulness with drawings. Then you get a formal written verdict that it does or doesn't need Planning Permission.

 

Bear in mind there are other restrictions on permitted development such as the need for obscure glass in side facing windows and retention of a strip of roof below the dormer. You should read this guide to be sure you got them all covered..
