Orangery Planning Permission & Building regulations

It may be that your particular room will fall into the permitted development category, but just to assume that you don’t need permission just because your neighbor didn’t is taking a big risk.

If you get it wrong, you could face a considerable fine or even be ordered by the local authority to remove the construction completely.

There are guidelines to follow that will, in most cases, allow a conservatory or orangery to be built without having prior planning permission, but that does not mean that you can bypass any building regulations at the same time – they are both different areas of construction and have their own rules & regulations.

Even the rich & famous have to comply – just ask Sir Cliff Richard
