It does take a special kind of person to live in a very old/listed building, imho. If you're used to airtight boxes with plastic windows and other modern 'conveniences' they might not be for you.
Old can definitely equate to money pits - we've previously owned everything from Victorian to Georgian to Tudor and have sunk tens of thousands (actually more like hundreds of thousands, i dare not add up the costs!) into them over a period of twenty-odd years....and none of those were listed!
Despite their lack of listing, we've always tried to do everything sympathetically and of course that costs ££££. I'm proud to say we've never succumbed to plastic windows and we're very used to adding multiple layers to keep warm in winter.
We don't mind living on a building site or rolling up our sleeves to tackle stuff that friends in their shiny, toasty new builds have balked at....
We've become fairly skilled at doing stuff ourselves (learning to lime plaster etc) and we recently built some huge oak framed windows despite no training in carpentry. All this has undoubtedly saved us a fortune over the years as I dread to think what we'd have spent had we not had both interior design backgrounds and more practical skills.
If you have a healthy restoration budget and deep pockets or don't mind waiting for trades experienced in restoring listed buildings to become available then It shouldn't be a problem.
It's a handsome house and if you don't have really young DC - we tackled our first big project (converting four flats back into the Victorian house the building was originally intended as) when we had an eight year old, who was well past the age of being into everything 😉 - I'd probably be more inclined to consider it. Access looks a bit challenging and I'm guessing there's no parking with the property?
