So a few months in to our build and I have to agree that self-build is hard work! It's also an amazing experience in which every day brings something new.
It's difficult to say whether this is physically the hardest thing we have ever done because I think age plays its part, we are late 60's or so and even though we are both fit people building at this age cant be compared to the house renovations that we have done in our 30's, 40's and 50's.
What I can say is that we wouldn't swap it for anything, we have promised ourselves that we would self-build for years and to be actually doing so is an amazing experience.
Onwards & Upwards!
