We're still waiting for Yawn's extension then I see. She's been bleating on about that since they bought the house.
Another 2-3 years apparently , so basically long enough that the turnover of her team will have changed enough for them to not be aware of it and start asking awkward questions about it in 2022/3.
It ain't going to happen. An extension like that costs money...money they haven't got. Planning, architects fees, building costs.....it's a bit more expensive than getting hubby to knock out a bit of wall and decorate with offcuts of wallpaper and some wooden hearts.
