I've read so many horror stories of people who decided to get work done on their house and ran into endless difficulties. Trying to find a builder who wasn't already snowed under with jobs. The price constantly rising. An ongoing shortage of skilled builders and building materials.
At the same the media are always showing us "dream homes" and urging us to refresh our "tired" home by....you've guessed it, getting the builders in! Be careful what you wish for, as they say.
There does seem to be a general fashion these days for "doing up" your home rather than being content with what you already have.
When I was a child, I don't remember anyone in our street re-doing their house. It would have been regarded as pointless extravagance. Our house was cramped but it never occurred to my parents to build an extension. They eventually moved to a larger house when I was 13, and never added an extension to that one either.
I'm not sure my parents even imagined a "dream home". If they did, I suspect it was simply one that was well looked-after. My father was forever repainting one room after another and keeping all the windows clean. That was good enough for him.
Dream homes are fun to read about but for us that's as far as it goes.
