Tanya Schoenroth Design That's a porcelain tile from Euro Tile (eurotile.ca). The product code is CE.HAB1224.NAT.SAB from the Habita series. The photo doesn't quite do it justice. The entire product line is quite lovely.

Tanya Schoenroth Design This is called a blind corner unit, which recesses back into the corner when closed. The shelves are attached to the door and pull out for easy access when it is opened. This particular unit came from richelieu.com, but you can get similar products from other hardware suppliers (try Lee Valley). Richelieu deals only to trades and any cabinet maker would have access to their stock. These cabinets were custom made. In order to add the unit to existing cabinetry, you would need a minimum amount of space (as specified for the specific product, depending on source). Those dimensions are listed on the company website. FYI, blind corner units are significantly more costly than a lazy suzan unit, but much more functional. They also require a different cabinet configuration. Where a lazy suzan takes up space on either size of the corner, the blind corner is accessed from one side only.
