As attractive as window seats are, only a few older homes with deep dormers seem to have them. And adding a window seat has always been considered impractical. First, you need a niche that features a window. Then, the seat has to be custom-built by a cabinetmaker or trim carpenter to fit the exact width and sill height of the window. Not surprisingly, this approach is expensive and time-consuming.
This simple, do-it-yourself approach provides both the "niche" and the window seat, and an abundance of storage space. This seat was built under a 6-foot-wide kitchen window, but its design can easily be adapted for any size window in almost any room. The seat is made up of six kitchen wall cabinets and two 48-inch-tall bookcase units, which are trimmed with decorative crown molding. The window seat itself is composed of two 15-inch-tall, over-the-refrigerator cabinets set side-by-side.
