How to Build a DIY Corner Desk
Working from home made me realize how much desk space matters. Like many others, I faced the problem of fitting a good work area into a small corner of my room. Store-bought corner desks were either too big, too small, or way too costly.
I found a better way – making my own corner desk. After building three different versions, I learned what works best. Now, I want to share my tested method with you.
In this guide, I’ll show you the exact steps to build a corner desk that fits your space and needs.
You’ll learn which materials to pick, how to measure correctly, and how to put everything together without special tools.
How to Plan Your DIY Corner Desk
I spent a lot of time planning my first corner desk, and I want to help you avoid my early mistakes. First, measure your corner space three times – trust me, this saves headaches later. You’ll need both wall lengths and the height you want.
I recommend drawing a simple sketch on paper. Mark the spots where you’ll need support and where your computer or other items will sit. Think about your daily tasks too. I made sure to plan extra space on my left side for writing and right side for my printer.
For materials, I found that a solid wood top works best. But if you’re watching your budget, good quality plywood can work just as well. Make a list of all your must-have features before you start. I needed cable holes and a keyboard tray in my design.

Top Customization & Personalization Ideas to Choose From
1. Add a Built-in Monitor Stand
I created my monitor stand using a 12-inch piece of the same desk material. Here’s what you’ll need:
- A piece of wood (12×8 inches)
- 4 small brackets
- Screws for mounting
- Rubber pads for the bottom
Mount it 4-5 inches from the back corner. Add rubber pads under the stand to prevent scratches. Make sure it’s sturdy enough to hold your monitor’s weight.
2. Install LED Strip Lighting
For my desk lighting, I used:
- 16.4ft LED strip
- Power adapter
- Wire clips
- Double-sided tape
Place the strips 2 inches from the desk edge. Use wire clips every 6 inches to keep cables tidy. Hide the power adapter behind a cabinet. The light adds both style and function to your workspace.
3. Create Hidden Cable Management
Here’s my simple cable solution:
- Mount a wire basket under the desk
- Drill 1.5-inch holes for cables
- Use cable ties for grouping wires
- Add rubber grommets in holes
Keep the basket 2-3 inches below the surface. Group similar cables together. Leave some slack for movement. Place holes where your devices typically sit.
4. Make a Sliding Keyboard Tray
For my keyboard tray, I used:
- 24×12 inch wood piece
- Drawer slides (14-inch)
- Mounting brackets
- Wood screws
Mount slides 2.5 inches from the desk edge. Test the slide movement before fixing. Add a small lip at the front to stop items from falling.
5. Build Small Shelves
I added two floating shelves:
- Cut 8×8 inch squares
- Use L-brackets for support
- Space them 12 inches apart
- Paint to match desk
Keep shelves within arm’s reach. Test weight limits before loading. Add a small lip to prevent items from falling.
6. Add a Power Strip Mount
My power setup includes:
- 6-outlet power strip
- Mounting bracket
- Zip ties
- Screws
Mount it under the desk near the wall outlet. Leave room for plugs. Make sure cords reach without stretching. Keep it easily accessible.
7. Install USB Hub Access
For easy connections, I added:
- 4-port USB hub
- Small mounting plate
- Double-sided tape
- Cable extender
Place the hub at the edge of the desk for easy reach. Use a powered hub for better performance. Hide extra cable length in the cable management system.
8. Create a Headphone Hook
My simple hook solution:
- Cup hook or decorative hook
- Small wood block mount
- Wood screws
- Wood glue
Mount it under the desk edge or on the side. Make sure the hook can hold your headphone weight. Sand edges to protect the headphone band.
9. Make a Cup Holder Attachment
I created this using the following:
- 4-inch PVC pipe section
- Mounting bracket
- Screws
- Rubber mat inside
Cut the PVC to 4 inches tall. Add a rubber mat at the bottom. Mount it where spills won’t reach electronics. Make it removable for cleaning.
10. Design a Removable Writing Surface
For my writing area:
- 18×24 inch wood panel
- Non-slip mat strips
- Small cleats
- Wood finish
Make it light enough to move easily. Add cleats to prevent sliding. Match the desk finish. Keep edges smooth for comfort.
