‘Monstrosity’?!
It’s a house owned by an artist. It’s been decorated to her taste with hours of her own work. It would be a matter of a few hundred quids’ worth of paint to bland it all out to white again if that was your preferred look, and the house itself is lovely.
There’s so much greyness and conformity and bland, sheeplike trend-following, I don’t understand the impulse to shit on someone else’s joyful personal expression. You’re a long time dead so put whatever the hell you want on your walls.
This kind of comment is more of an indictment of all the people who are so completely lacking in taste or imagination that they can’t envisage a space any differently from the current owner’s choices.
