These pieces were made for my personal office and have served me well for years. Each storage unit has 6 D size plan drawers and square rooled plan slots under the drawers. On top the storage units are 48" wide x 55" tall X 22" deep with multiple shelves that can be positioned. The Center Piece is an inclined desk surface and can accommodate a drafting machine if needed. Finish and Structure is heavy. These units are custom tailored to the end user.
