Built-ins take advantage of every inch of space in a busy room - even when it doesn't seem usable. Built-ins can subtract clutter and maximize every inch of space in your home. Built in cabinets can be customized to fit in odd spaces and corners. Built-in desks are an especially great way to make use of otherwise dead space in high-traffic areas like your kitchen. In designing your desk, include plenty of shelves and drawers and don't forget to include provisions for PCs, phones, and faxes.
