"We really don't want something modern. We really want something more traditional - you know, so it fits. Maybe colonial with a touch of gothic flavor..." 

Not that there's anything wrong with being a glass rep (Saint-Gobain Glass India) but what's the point of all these softball questions?  Baiting the hook?

Maybe colonial with a touch of gothic flavor

this should be on a t-shirt.  or a coffee mug.  maybe it can become a lolcat meme

its hard to detail a drywall wall without base moulding and get it executed properly

flat roofs leak

white walls show fingerprints

gaggenau stoves are a bitch to cook on

where do home owners hide all their shit?

Every problem mdler described is a response to poor craftsmanship and client hoarding. If you are referring to that Modern anyways, it fails because the values and reality became disconnected. If you're talking about contemporary, its because people rather have a larger, poorly built house, than a more compact well crafted house. The difficulties are social issues (just look at the majority of "architecture" magazines in your bookstore).
