A Cornice Box for Kitchen Windows

When you buy your first home, choosing the right window treatments can feel really intimidating. There’s a lot of stuff to figure out, right? Well these clients are really struggling with that – and a big beautiful window to look out of when they’re doing dishes but when you look out the window…nosey neighbors. So we’ve got a really fun DIY treatment today called a cornice box to rectify that situation.

 

  1. Get Started: Build, Stencil and Mount – Measure the window opening you want to cover. Your façade will be slightly wider than the window. Add at least 2″ in width to make it larger than your window frame.
  2. Cut the boards – Measurements will vary depending on your window width. The window we’re working with was 52″ wide, so we cut each of our long horizontal pieces 54″ to span the window molding. Because we wanted to leave plenty of light in the space, we measured and cut two vertical frame pieces each at 24″. We chose not to cover the entire window to allow for more light in the kitchen. The area we covered blocks the neighbor’s sight line. Place the 54″ pieces outside the 24″ pieces, forming a rectangle. Before screwing the two boards together, apply wood glue to the joint. This helps all wood working projects stay together longer.
  3. Attach the boards – With a power drill, screw the frame pieces together into a rectangle using 1 ¼” wood screws. Two screws for each of the four corners, held our project together nicely.  Pro Tip: Did you know that a 1 x 3″ board isn’t actually 1″ x 3″ in dimension? When boards are first rough sawn, they’re 1 x 3″ but by the time we get them, they’re 3/4″ x 2-1/2″.
