Janet Schweitzer's "Obra" system produced by Pace is an innovative and elegant design. Combining aluminum uprights, glass shelves, and a cabinet clad in rich burled wood, these two single bay units offer both open shelving and concealed storage. 
 
They each have three glass shelves (one with integrated light) and a cabinet that has two doors concealing a single shelf. 
 
Each unit measures 72"h X 30"w X 18.75"d
Price is for the pair.
