Off road parking, absolutely. So house B, it is a blank canvas and you can add character back in.
Open plan means noise and that curry you cooked lingers, conservatories are cold in winter and hot in summer. We inherited one in the last house, never again. I also hate the retention of the original kitchen window.
House B has a lot of potential to do things with the downstairs rooms, turn one into a dining room, home office, second sitting room, gym etc etc.
I get that house A is prettier, but B has a lot more potential.
