When it comes to simple details with bold impact, these “window shelves” fill the bill.

In taking the rarely used ledge of an existing deep-set kitchen window and building shelves to display collectibles and store glasses, the designer fulfilled her client’s wish to add color and interest to the space while creating privacy from nearby neighbors and still admitting plenty of natural light.

Remodeler Bill Dolan of Pine Street Carpenters, in Westchester, Pa., who worked on the project and built the shelves, says that the existing deep sill existed due to the “almost institutional-grade structure” of the house — an 18-inch-thick exterior wall of 12-inch cinder block with 3 inches of rigid foam, and exterior stucco and interior plaster.

Dolan’s team crafted the shelves from 3/4-inch birch plywood with a strip of 3/4-inch-by-11/2-inch poplar on the front edge, all painted white.

The removable shelves are held in place by Mockett stainless steel supports, located on the sides and on the center mullion.
