Is it possible to build an "outdoor office with a bathroom and kitchen" under Permitted development, and then once built, change the interior to add a bedroom and apply for a change of use as an ancillary accommodation? If someone did this they wouldn't need an initial planning permission. How strict and observant do councils tend to be with permitted developments and how do they go about enforcing an inspection?

Thanks everyone for your replies and input. There is lots of helpful things you’ve shared that I was unaware of. I will have a look at simplifying the windows/ doors and also do more research regarding regulations and stuff.

Hello, Me and my wife have a small plot of land and hope to build our own house. We have researching timber frame house kits and are visiting the NSBRC in Swindon next week for more insight. The thing is we don’t have much money and want to avoid mortgages. Our budget if we are able to borrow from family is roughly 60-80k and we have lots of friends and family that are electricians/ builders etc that are willing to lend a hand. We don’t have any planning permissions but hope to build a house like the Scotsframe “Calder” floor plan. i joined this website to learn and get advice as we start our journey!
