Idk. My mate started his building career doing high end reno projects - 00's Primrose Hill celebs, pre-crash bank MDs, etc. None of the wives were ever completely happy.
That's prob a Dif issue though, I imagine they are just picky dicks who don't actually try and work with people to find solutions, whereas I'm a picky dick who totally works with people.
The bigger the budget, the more folk moan as ive found and if people want perfection they need to find a big big budget as that costs money for fucking about.
It is perfect if you are golf club rich.
