For such a high price I don't think it's that nice, only meters away from the road, the house is quite near other houses, not that much land and near industrial units. They really overpaid for it. I expect if she realised how cold and yet still expensive to heat it would be in the winter she wouldn't have bought it
(I'm guessing they have to get oil delivered too?)
I can't see any totally finished photos from the extension, it didn't fit in at all from what she shared of it nearly finished. You can do modern extensions and get it right, but her's looked like a glass box tacked on.
