It's a very received, very masculine idea of "good taste" and a bit of a cliche. Some of the design is very good, even classic (I can spot some Holmegaard glassware there!), but it lacks personality and feeling taken as a whole like that.
The best thing about it is thw beautiful high ceilings and cornicing and it almost does everything it can to undermine those points with squat ugly chairs and dark walls to make it look smaller and take the eye away from the nice bits. I don't think the pieces look good together at all. I would feel so uncomfortable in that space.
I think Macintosh gets the balance of modernism and design just perfectly. Seeing his home recreated in Glasgow was one of the most inspirational moments of my life: People can LIVE by their own design!
