Were few years off an extension yet but it's just made me ponder a bit.

The house we have has an extended kitchen, looks like it's been there a good 20 years or so. its got an old outside loo tagged on the end.

We'd like bifold doors on the end eventually and to add a pitched roof (currently flat) so would like to extend it by another meter or so so its flush with the attached outside loo.

So, can you add upto 3 meters onto an established extension without planning permission?

Simple answer is no. Planning permission is needed on all permanent structures that leave a footprint. Furthermore depending on where you live their could be many further reasons for needing planning permission. For example changing the external look of a building or even changing internal structural walls.

iroof - I'm afraid that is wrong. Some development can be carried out as permitted development which doesn't require formal planning permission. At the moment, those rights have been increased temporarily to encourage more building, so even larger additions may not necessarily require full planning permission.
green - it will depend on the size of the previous extension, what type of property it is, whether you are in a conservation area etc. This link may help but you should speak to your local council for advice.

We are extending by three meters and don't need planning permission, just building regs.

However you are extending on an extension so I'm guessing you would. I think you can go up to four meters without permission on a a detached house and three on a joining house.

Our architect checked with the council and we didn't need it. You do need to find out.

Thanks, I'd ring the council before we did anything, after I find that money tree it just made me think really. My husband wishes I'd of never found this board, it gives me too many ideas ha.

You need to be aware that if you are in a conservation area, green belt or AONB there may be other rules too. Best to check with the Council. If you add a pitched roof, you are also adding volume and that can also be an issue for some councils. If other people in your road have similar extensions to the one you propose, then you will probably be Ok.

Thanks. Yes the neighbours all have similar extensions to how we'd want ours. I keep looking at theirs with envy ha.

We're mid extension. Part was across the original house and was under permitted development and part was across an exisiting extension. That part needed planning permission. Planning office told us to split into two applications.
