DH & I are in the process of buying a small barn. It’s currently covered in Ivy and brambles. Downstairs will be a utility room & bootroom, upstairs will be a bedroom with en-suite. We’ll be building a house which will be attached to the barn by a glass corridor. If you’ve ever built a house or converted a barn, I would love to know what you wish you had done differently, or what advice you would have. Have never built a house before.
