1. Go For a Shelf Computer Desk
This is possibly the easiest and fastest way to get yourself a nice working desk. You need a couple of sturdy shelf brackets and a flat surface of your choice to act as a desk. Make it adjustable and use it both as a stand-up and as a sit-down workstation. For as little as $50, you can have one of the most affordable and effective desks out there.
2. The Trestle Desk Is Beyond Cool (and Affordable)
Often referred to as the sawhorse or the A-frame desk, this surely is one of the simplest ways to create a comfortable yet chic workstation at home. All you need are two freestanding trestles to use as edges and a board to lay on top. Visit your local hardware store for some cheap workshop sawhorses, and you can easily get this project done for under $70. For a more stylish appearance, you can get the IKEA Finnvard trestles, but keep in mind that they will double the cost of the desk as their individual price is $50.
3. An Adjustable Desk
Adjustable standing desks are not only good for your posture and health but also for saving space. You can create a manual counterweight adjustable piece or dive deep into the DIY of electronics and make it move with the touch of a button. You can find most if not all of what you need at your nearest Home Depot or a similar store. This project will not only save you a ton of money, but you can also work on customizing the desk to the perfect height range for you.
