I've been pining for have a lovely airy light filled downstairs for years. Knocking walls down, open plan kitchen etc. Now I am wondering whether the Victorians didn't know a thing or two about keeping houses warm in winter. Small rooms, with doors. Each room for something particular. Thick curtains. Petticoats and shawls. Waistcoats. Pudding.
Does it cost a lot more to keep an open plan family room warm?
