exposed parts in cabinetry  

Three very different examples.
Which do you like better, the handmade quality of exposed joinery or the inside-out deconstructed/reconstructed approach to casework?
While I can also appreciate the initial appeal of pieces such as the Rietveld sideboard as experimental exercises, the longer I look at those exposed horizontal surfaces, the more I see places for dust to accumulate.

Ha.
As the maker of the occasional mobile, I can say the same. Anything we make then becomes a maintenance issue. I think we just have to assume that aesthetics trumps housekeeping . . . ?
Anyway, I have always been fond of the exposed-structure (or structure-as-aesthetic) school of design -- which I feel is a defining (if not exclusive) characteristic of (some) modernist design. Its earliest self-conscious application in furniture might be found in the work of the Craftsman school ? Rietveld's use of this mode has always been associated with the Constructivist movement, of course. All of these guys have influenced my own work, to wit:

Its like an adventure for your eyes....
The first two mostly, for different reasons although I think the Reitveld piece as shown was as hand crafted as the Krenov, I really like the razor thin gap of line on that and how the drawers hang from the runners that become the handles and also the implication of infinite scalability in the the sideboard.
I started on a mock up yesterday of something smaller but similar, just shooting the runners and testing some half laps, and it was a like a whack over the head as to how scrupulous you have to be, no hiding behind veneer or a case or using anything below a certain grade anywhere.
