Has anyone have any experience of doing this? We've been advised by our architect that it will give us a lot more usable space in the loft conversion but it will cause a huge amount more disruption and we'd need to move out while it's done. We have seen a conversion in a house the same footprint as ours where they haven't done it and although they did have a double bed and ensuite bathroom it was pretty tight. Oh yes I need to add that we are a tall family!
