Thank you, good people! For a non-Brit, this thread is comedy gold 😆. Such delightfully sneery snobbery.
For what it's worth, I like the exterior; it's a beautiful house. Don't care if it's 'new build', 'non-Victorian', 'without acres of land', it's still a very nice-looking house. Interior is not to my taste, but it's not my home; obviously, the owners liked it. Best of luck to them with the sale.
If you like it, OP, and can afford a similar house, go for it. It's so difficult for me to comprehend someone choosing where/how to live/decorate based on perceived 'class'. Stick an Aga in or whatever that medieval nonsense is called, and be done with it. A few fridge magnets for 'evidence of travels' wouldn't hurt either, I guess. Just choose something more upmarket, so St Anton/Val-d'Isere/Tuscany rather than Benidorm.
