Permitted Development Query

[William]

Hi 

I have joined because of this very informative forum. 

My neighbour built a single storey garden studio at the end of his garden to his terraced house about ten years ago. He carried out this building with a Certificate of Lawfulness. 

 

Last year he converted the roof space of his main house and created a dormer window which projects out beyond the roof slope, creating as additional volume build of about 40 cubic metres. He did not apply for planning permission nor did he apply for a Certificate of Lawfulness. 
 

He maintains his roof space and dormer window complies with Permitted Development Rights. 
 

My query is this. Having made use of his permitted development rights for the the garden studio, does he in fact have the benefit of PD again for the roof conversation with the Dormer Window. 
 

I would really welcome your views and opinions on this as I would like to challenge the validity of his dormer window. If the dormer window is legal, it would mean I can do the same.

You do not say where you are.

 

Between those two, and assuming he still has PD rights ie have not been removed, it is likely not to clash.

 

However, they may have gone beyond PD rights in detail, but TBH if it is marginal at this stage they would be likely imo to get retrospective permission anyway especially if it is an area where these are common. If they have driven a double decker bus through rules in eg a conservation area then that would be more serious.

 

You could take a piccie and email the Planners for an opinion and the actual rules for  that property. I would say first just enquire, and do not automatically ask them to enforce. It could upset relationships for many years.

You don’t need planning permission for dormers on the rear or side of a house, as you say it’s restricted to volume. If you want to do the same then why not, you just need building regs.
