Our first build was also with Celebration Homes and from start to finish it took nine months.
Im really hoping HGWA are turning this around as im now getting a real feeling of dread reading all these posts. As like most people paying rent (hate the rental we are in), kids getting older etc doesn't help. We were told because our land was titled and we are doing our own carpets, tiling etc after handover it should move quickly.
Building your new home should be a exciting time.
I will say though Rachel our contact at HGWA has been great so far.
