Was meant to have extension built in the next two months with confirmed builder last year. The firm has now stated due to shortages they are 3 months behind and the people before us have only just started (meant to be a few months ago) and are adding bits on... So likely not going to be able to start for another 6 months. Is this normal? The building firm is a well known firm and has a good rep... Is it just like this at the moment with delays?
