Yes, we were in a very similar position about 12 years ago, when we were both 64, living in a barn of a Victorian terrace, with 3.5m ceilings, costing us a fortune to keep heated. Also large gardens, which certainly took some tending. Sadly, my widowed Mum passed away, but at least that provided us with the impetus to sell up and to move into her 1970's-built 2 bed detached bungalow. It needed some improvement, which we gladly carried out with an eye on it being retirement friendly, and we also built a large, brick garden room onto the side where a small conservatory had been, with picture windows on 3 sides. We spend most of the daylight hours in there now. The gardens are gravelled, low maintenance, with trees and shrubs. So pleased we moved when we were both physically and mentally capable of coping well with that, and now that steps and stairs are becoming a bit of a challenge for both of us, so grateful that all is on one level. All I can say from our own experience is that we've never regretted our move.
