Hi all. My son has a tiny box room ( think can't even fit a set of drawers, a wardrobe etc.). Years ago we built a cabin bed over the stair head as it wouldn't even fit a normal single bed in there. As he is now approaching teens and is really tall for his age- he is just struggling in this tiny room. He also has a knee condition that can make climbing up and down onto the cabin bed difficult at times. So I've got a quote to move the wall in his room to take about a metre off my bedroom. I've been quoted £1775 for this. Also an extra £400 to build storage unit over the stair head. Does this sound reasonable?
