I find it telling that the 'interior designers' who own it don't seem to want to be identified (according to that article)! Imo, they're not terribly good if interior design is their profession.
It's actually a very small house (although there's apparently scope to convert the attic rooms) with loads of outbuildings making up the overall square footage. Additionally, a few of the rooms are very narrow.
I'm a period property person, so it wouldn't appeal to me, but, being very much a maximalist when it comes to my own home, I'm in the 'better than beige' camp - at least it's a house with personality. And whilst I hate much of it, I not only admire the vendors' vision and commitment, but also actually like one or two elements. The G.O.A.T swim spa looks great fun (but then I miss my hot tub!).
