Actually bluntness is incorrect. A listing, any listing, covers the building in its entirety. Inside, outside and curtilage. Always. You must not rely on the list description to make assumptions on what is and isn’t scheduled
Actually I am correct. Because a listing is based on what was in place at the time of listing, and what is in the listing. Your statement is correct but you've stopped short of saying it covers its contents, like a kitchen etc.
So if it says the kitchen is also listed then it can't be changed without permission, if it doesnt then it can be changed, it doesn't need permission. The listing and what it details is absolutely critical.
The listing is to preserve the original fixtures and fittings as of the time of the listing. If things like the kitchen or carpet are not called out in thr listing, and not deemed original, then they can be changed without permission. They are effectively like temporary contents. You do not change the fabric of the building by changing them.
Thr grounds can also be changed. You can plant trees, even build a small patio below a certain size,, without permission,what you can't do is build a modern building in the grounds, or a patio over a certain size.
If you think of why a building is listed you'll understand it. And I'm talking grade 11, you may be talking grade 1, but if you think of why it's listed it's because it's of historical interest. So they wish to preserve the building and the original features for historical interest
No one gives a shiny shit about a twenty year old kitchen in a two hundred year old building. Or if you put carpet down over the original floorboards. Nor do they give a crap what colour you paint the walls internally. No planner wishes to be bothered with that shit.listings are not intended to make people's lives difficult to the extent you're trying to make out.
What they care about is the external appearance, so you can't change the windows, build conservatories, change the colour of your front door. Without permission. And you can't knock down walls or remove original features like cornicing or fire places inside. You need to preserve it. But preserving it doesn't mean you need to ask permission to paint or renew your kitchen or bathroom, unless it's original and on the listing, and that would be very, very rare indeed.
Ours has a porch built on it, a garage in the grounds. Both required permission. Both got permission. So getting permission doesn't mean you can't do it. It means they want to see what you want to do to ensure it's in keeping with the building.
And you'd have to be a total lunatic as said, if you wished to buy a listed building, start adding things out of keeping, ripping out ancient fire places or adding upvc windows. But people do that's why you need permission.
But changing a twenty or thirty year old kitchen on a four hundred year old house? They don't care. I know as I live in a listed building, I have replaced my kitchen and I have asked the question. I will also replace my bathroom next year. The bathroom that's about twenty years old. And was put on decades after the listing in a four hundred year old house. No planner wants to see my design if I'm not ripping out walls etc. Why. Because my crappy bathroom. Like my crappy kitchen did not need to be preserved for historical interest.
And the house needs to be habitable. Not a museum piece filled with shitty seventies Kitchens and bathrooms.
