It's very draining. You can't get things feeling clean and neat in that state (and I'm no housekeeper)
This time last year I was constantly painting, painting and repainting. Our house had been extended by a previous owner leaving a very peculiarly shaped and proportioned potential master bedroom. It took 3 years to move walls, knock and fill windows and create a pleasant master bedroom and en-suite. Mostly ourselves other than the windows!
I'm so glad that it was done by Christmas but I was pretty burned out by it then. We also had an overlapping rush job to convert the box room into a functional bedroom for DS1 to move into which involved contructing a floating mid-sleeper bed as the room was too snug to assemble a standard bed frame)
The hall/ landing still have unpainted artex, plasterboard walls and a 3 year old rough, temporary bannister to deal with as an aftermath of the bedroom and DH and I decided in March that we were going to pause on works, particularly with him working from home, and access to shops and supplies being more awkward than usual. There's just no escape from it, and although it's dowdy and dull, it's just not a good time to cope with additional complications such as having to book the tip 2 weeks in advance or drive to the next county!
We've had a leaking roof over the last 15+ months. I was emptying inches of water from the drip pan every other day last winter when it rained incessantly for 9 months. We've just had it done having struggled to get roofers with relentless rain then lockdown, but its been bodged and we've been exploited and it needs starting again again (after initially being built badly before we moved in). DH might be a slow, meticulous perfectionist, but at least it's done properly without nasty, expensive surprises.
