One of the biggest questions when we decided to add an office function to our guest bedroom was: where does the desk go? Correction: since there are two of us, where do the desks go? This was a tricky decision in a modestly sized room—just 10′ x 10.5’—that also needed to accommodate a sofa that folds out into a full bed for occasional guests. A little pre-planning helped, so I sketched a simple, not-to-scale floor plan to visualize the possible desk placements.

• Zone #1 sounded appealing because whoever sat there would have a view of the backyard. But with the couch so close it felt a bit cramped for the other person. We also planned to add a bookcase on that wall to balance the uncentered window, so Zone #1 didn’t end up being ideal.
• Zone #2 felt like the best choice: it was the longest uninterrupted wall and offered the most flexible layout. The downside was that it might require a custom desk to maximize the length without interfering with the sofa bed when it’s unfolded.
• Zone #3 only had room for one desk. That could reduce the need to find one long two-person desk, but having one of us with our back to the other isn’t great for collaboration or for seeing each other’s screens.

We chose Zone #2. It made the most sense because it gave us a long, blank wall in front of our work area—a perfect place to hang art, pinboards, or other productivity-enhancing items when we finish the room.

Next challenge: finding a desk that fit that wall. We had about 7 feet between the window and the door when it was fully open, but only 21 inches of depth before the folded-out sofa would interfere. After searching and even thrift-store hunting, two contenders emerged: a modular storage-based solution and a leaning bookcase desk. Neither felt right in person. The modular option was close but didn’t fill the space the way we wanted, and the price didn’t make sense for us. The leaning desk was pricier and didn’t truly accommodate two work areas without adding even more bookcases to the room.

So I decided to build a custom desk. I’d been eager to try the Kreg Jig on a larger project, and building a simple desk felt achievable: screw a few legs and rails to a big slab of wood, right? The main logistical hitch was getting a long piece of wood home—we only own a Nissan Altima, which doesn’t swallow 7-foot boards easily.

Then we remembered a hollow-core door that had been living in our garage. It once belonged to the bathroom linen closet and had been in the way for years. The door turned out to be almost a perfect size for the space—just under 7 feet long and about 18 inches wide. Best of all, it was free and already on-site, so there was no hauling involved.

Instead of following formal plans, I borrowed the basic leg and rail proportions from our dining table, which had the look we wanted. With a few quick measurements, I picked up wood for four legs and rails: some 1×3 poplar for rails and four chunky 3×3 poplar posts for legs. The cost was about $70, our only out-of-pocket expense since we already owned screws, filler, primer, and paint.

Prep work came first. I removed the door hinges and filled the hinge mortises with wood putty because that side would become the front of the desk. We kept the handle hole on the back side to use as a convenient cord pass-through for chargers and power bricks—a small but useful feature. The door had spent a couple of years in the garage, so it needed cleaning and some light sanding to remove peeling paint before priming and painting.

We shortened the door a few inches for breathing room on either side, using painter’s tape to mark and reduce splintering during the cut. The circular saw revealed the hollow interior of the door; since that end would face the wall, I smoothed it and left it as-is rather than fully sealing it over.

I primed all wood parts before assembly to protect the finish during construction. For the legs, I used the Kreg Jig to drill pocket holes on the inside faces and then attached each leg to the underside of the door. I set the legs in slightly from the edge using leftover furring strips as guides so the legs would be evenly placed. Clamps helped keep everything steady while I drove the screws.

After attaching all four legs, I measured and cut the four side rails, drilled pocket holes, and screwed them between the legs and into the door for a stiff frame. Because the door is hollow-core, I was careful with screw angles so most fasteners hit the solid internal frames at the door’s edges.

Rather than recount every bit of sanding, filling, priming, and painting, the finished result is a simple, white desktop built from repurposed materials and a bit of elbow grease. The desk is 18 inches deep—plenty of room for our two laptops and a few essentials—and custom-fit to the wall so the sofa bed can still fold out comfortably. The total cost was around $70, and the satisfaction of building it ourselves was worth more than the savings.

Now we’re outfitting the space with chairs, storage solutions, electronics, and wall decor. We’re taking it slow because we have a newborn and are juggling projects, but the desk is already functional and has handled several days of work well. It’s become a practical, economical solution that feels right for our small guest bedroom office.
