Hi there. Totally agree with you. Building is quite difficult process which requires a lot of effort, nerves and resources. Of course if you have necessary skills and experience you can do a lot of work by yourself, but personally I prefer to delegate such tasks to professionals. For example I'm searching good building contractor for basement renovation, I even ordered engineering bricks from https://www.mgnbm.co.uk/building-products/bricks-blocks/engineering-bricks/ for this purpose.
