We built during COVID and to say the challenges were there would be an understatement. However, we ended up with a beautiful house, solid, and sold above figures for our area. COVID increased prices and Nanche/Keycon have done all they said within the contract price. I would not use volume builders to save my life. My daughters house has cracks, structural defects using a volume builder! Whilst the build was slower due to COVID and lack of trades, I would advise to purchasers let them do their job, you will be happy in the end. (I am not a friend, staff member, and was actually at one stage an unhappy customer as well). Once I stood back and took a breath, I realized how I could work with them rather than against them. Not an easy time for anyone, especially a business.
