In some cases, a window backsplash is preferred because of a lack of natural light. An interesting example is the summer house designed by BAK Arquitectos, where concrete was used for countertop. Even though it has a very open layout, there’s not really an abundance of natural light inside the house. In order to have a kitchen that’s both bright and functional in terms of storage space, they chose the window backsplash strategy.
All cutouts, edges, and surfaces must be treated to keep moisture out of the wood. This makes undermount sinks ideal for wood countertops, according to Paul Grothouse of the Grothouse Lumber Company. Drop-in sinks go well with clear-coated or factory-finished countertops but need a flexible sealant beneath the rim.
The Brown Residence by Lake|Flato Architects has a pretty interesting kitchen. The backsplash window doesn’t look directly outdoors but rather into a hallway. It‘s an interesting way of connecting the spaces and ensuring a seamless transition and a continuous flow between them.
