Traditional with a twist
Either I'm pretty unsophisticated in these matters or those are some very subtle twists - the gold leafed ceiling treatment in the dining room and the shirtless Highlander/Cossack in the living room?
I thought the safe, timeless, go-to in sophisticated gay design that wouldn't become passe (like, say, mid-century modern) would be traditional but with the twist being a few pieces of modern art, sculpture or fixtures. Like a room done up in Biedermeier or Russian Empire with a Picasso and a Pollack thrown in, lol. Or, seriously, a few of your own pieces. Don't you have a favorite artwork you've created yourself where you love the colors enough to build a room around it?
