Bedrooms in my house are very, very small. A queen-sized bed fits – but without much room on either side for nightstands or storage. I had a small nightstand, but after piling a large alarm clock and lamp and anything else on it and it looked ridiculous. After pouring over ideas, I thought about making a built-in solution. Now I have a huge shelf to stack my junk, extra books, lamps, blankets, trinkets, whatever! Also, figured if I was building it, why not give it some doors and use it for extra blanket/pillow/sleeping bag storage? This works great for me, and maybe it would for you too.
Plans are based on my build, but you can surely adapt them for any configuration. For facing boards, I used cedar fence planks, mainly because they are readily available and inexpensive. I would have loved to have built this with some reclaimed Fir, but I was impatient and started building and couldn't find what I wanted to finish the job over the weekend. If you want antique wood, search some out before beginning your project – however here's my plan based on 8ft x 5.5in x .5in cedar planks.
First step: Measure your space and sketch it out. I always recommend a sketch for built-in projects. If you plan this part correctly you'll limit the amount of lumber you use and have less cuts to make. As I built, my plan kind-of adapted, and I had more cuts to make, but I'll give you hints to avoid this. Things to remember: 2x4s are actually 1.5 x 3.5 inches - so note actual lumber size when formulating.
Build the facing frame: If you have uneven walls like mine, measure and cut your floor-length board first. Measure and cut your verticals, and make sure they are close enough together for decent support - no further than 18" apart. I cut five verticals, 24.5" each. Lay your verticals on the floor, then screw your floor-facing board to them with your screws. Once assembled, set your frame in place, and measure and cut your top board. Because my walls bow, it was important to cut this board to it's location height. If you have plumb walls, you can completely built out the frame and set in place. Before screwing the ends of the top boards, level your frame and screw the end boards into the wall. Make sure you're anchoring to a stud, because this is your main support/anchor points. I chose to not screw the frame into my floors, and the wall mounts were secure enough to accomplish this. After your facing fame is in place, I attached 2x4s to the back wall as supports for my top doors. Make these even height with your top frame board. I left space between boards to feed electrical cords behind the doors easily. Then for added strength, I attached the facing frame to the back wall with a 2x4. This board also helps support the door tops, which will rest on the facing frame top and the back wall boards.
Facing boards: Now your frame is complete and secure, you can begin the facing. My cedar fence boards are VERY rough, so I sanded the harsh surface with an orbital sander and heavy grit paper. This left them still rough in a rustic way, but not splintery. After sanding, sweep off the sawdust. Between the boards and the frame, I attached heavy plastic, so when I stored things inside, they wouldn't catch on the board surface. This is just an option if you use rough boards and don't want to snag anything that might rest against them. Then nail your boards over the plastic covered front frame. I used small finish nails that would be easily hidden. Make sure your boards are level and then nail them in place. If you've measured correctly, your top facing board should come above your frame top by 1" so your doors will be counter sunk. (I did not make this important calculation before-hand, so I had to attach a cut trim piece to take up the gap.)
Top doors: Once your facing boards are in place, you can measure you top door depth. Again, my walls are un-even, so each one is different and cut accordingly. Don't make them too snug either, mine each have a small gap at the back, so I can easily feed my lamp/clock electrical cords though. The top boards are just made with the fence planks, two support boards each, glued and attached with small screws. For handles, I drilled holes and used scrap leather strips, fed through and knotted. You could use drawer handles, rope, large finger holes, whatever you like.
Finishing: You can finish your facing boards and doors before attaching, but I finished in place. I used water based stain to darken the boards, let dry and then coated with water-based poly. I used water based products since I'll be sleeping in here, and the fumes are way less noxious. Because the boards are very coarse, I used three coats of poly with a vigorous hand sanding in between. It was more about building up a thick finish to prevent splinters than creating a smooth topcoat for me. After a day or two drying, I could place move everything back in place.
