Building a bay window desk is considered a simpler ''home improvement'' project than building a wall-mounted desk, yet bay window desks are known for needing extra supports, in the form of the window's walls, to support the entire desk.

Bay windows themselves are designed to allow more light to pour into a room, which makes them a great addition to a bedroom. Transforming that same bay window into a desk area is a great way to add a unique flair to any room.

Find The Levels
-----------------

Find the level lines around the particular bay window. Start by drawing a line at the window, at least 30 inches away from the floor. From there, mark the position of the wall studs by the level line.

Take Measurements And Attach Back Cleats
-----------------

Measure the back wall at the bay window - you'll want to cut a piece of 2 by 2 lumber to correlate with that length. If the bay window is angled, miter the edges of that lumber.

You can then place that lumber at the back wall's level line, screwing it in place with deck screws. Repeat measuring and cutting the lumber as appropriate for the remaining walls. Attach them as per the previous board, which will create the supports or wall cleats for the desk.

Take Measurements And Attach Side Cleats
-----------------

After doing that, take measurements of the bay window's opening, cutting another piece of lumber to match. This piece of 2 by 2 should rest at the opening, with both abutting ends to the cleats on the side walls. Attach the cleat with desk screws into the abutting ends of the aforementioned cleats.

Take Measurements And Insert Planks
-----------------

Take measurements of the in-between planks, starting by measuring the distance from the back wall cleats to the cleat resting across the opening. Cut two pieces of 2 by 2 to match. These pieces should be inserted between the back and front cleats, secured in place with corner brackets and screws.

Take Measurements And Attach Desktop
-----------------

To get the measurements for the desktop, measure the bay window's recess. Cut out the desk top, using the measurements from plywood or medium density fiberboard. After preparing the desk top, position it atop the cleats and attach it, adding screws in 5-inch intervals around its perimeter.

Finish Up
-----------------

Fill the remaining screw holes with wood putty. Let the putty dry, sand down the desk top and you can later paint the entire desk.
