Wow, your building project is really coming together! It's fascinating to read about the progress you've made, especially with the plastering and flooring. It's true that saying "love covers a multitude of sins" takes on a whole new meaning when you see how plastering can transform and beautify the walls, hiding all those rough edges left behind by plumbing and electrical work.
I totally get the delays you faced with things like getting the right plastering sand and dealing with the unpredictable weather. Mother Nature can be quite the project manager, huh?
I'm also curious about your choice of PVC for the ceilings in the two rooms you'll be using. I saw some people are using Timber Joists for those kinds of projects. Have you tried them?
