Built-in cabinetry and finish work have applications in more places than just the kitchen or entertainment center.  The creative use of standard cabinetry and some custom carpentry can add unique spaces in areas like mud rooms, bedrooms, or offices. Built-ins are a great way to take advantage of otherwise dead space under stairs, and at the ends of hallways.  A custom built-in bed or window seat can dress up the appearance of an otherwise plain and unremarkable space.  At REEF, we have created several built-ins for our new home and renovation project that add both function and style to these homes.
