Not sure we're quite ready for full 'Passivhaus' but I'm very keen to aim for 'cheap to run'

Ah, I don't live there. A job we did a couple of years back: https://www.walesonline.co.uk/whats-on/travel/historic-railway-cottage-been-transformed-14536344

Hello, Odd for me to join a self build forum. I've been doing it for a living since 1990 But a small firm specialising in renovation work to old listed buildings. I'm just setting out to get planning for a modern insulated house, for myself; having lived in an old stone house for 30 years. Hoping to learn about insulated raft foundations, air source underfloor heating and triple glazing! Cheers, Mark
