Tools Needed To Make The DIY Kids Loft Bed

Before we started building the loft, we knew we needed to take out the clothes bar and the bottom shelf in the closet. We patched the areas where those had been. We also filled in the hinge hole areas (that the door hinges left behind). You can find our tutorial for doing that here.

Our closet has trim finished on the inside of the door jam, so we knew we would need to address that so that the loft would sit level against the door jam. For us, it worked best to take the trim off, install the loft, and then re-cut and re-install the trim.

Once you get to a blank slate in your closet, you can get to building.

How to Build a Loft

  1. Measure and Decide on Height
    1.  Our back wall measured 77 1/4 inches. We cut a 2×4 on the miter saw at that measurement.
    2. Our side wall measured 22.5″ each. We cut 2 2×4’s to just a tick under 22.5″.
  2. Find the Studs and Attach the 2×4’s
    1. Attach the back 2×4 (77 1/4 inches long) on the wall where you want the base of your loft to be. Ours started about 50 inches from the floor. Make sure you are using your level and then screw two (LONG) screws (we used deck screws) in on every stud on the back wall. 
    2. Take your two 2×4 side pieces (22.5″ each) and attach them on the wall. Even though you have measured out your box, make sure each piece is level with each other as you add on. For one of the sides, we could only find one stud (on one end). This is where we used the angle brackets. They allowed us to fasten the 2x4s to each other to add extra support on the end without a stud.
    3. For the front piece, we waited to measure until the back and sides were on. With the trim taken off where you need your front 2×4 to go (or notched out) measure how long you need your front board to be. Ours measured 74.3″. Cut your board. Attach your board to the side 2×4’s. Drill into the door jams for extra support.
  3. Add Cross Supports
    1. Measure inside the box from the front 2×4 to the back 2×4. Ours measured 20 3/4″. We decided to have two cross supports spaced evenly. We cut two 2x4s to a hair under 20 3/4″ so that we could get our boards in. This is where your fence brackets come in. Use fence brackets to attach to the back 2×4’s. On the front, you will be able to drill through from the front 2×4 to the cross beams.
  4. Cut the Plywood Top
    1. Measure the “box” where your plywood will sit. We had leftover scrap plywood that we cut and screwed in to the supports. 
  5. Trim the Loft Out
    1.  The front of the loft needed something a little bit nicer than a 2×4. We picked up a white oak board to have it be the face of the loft. We primed and painted it. Then, using a finish nailer, we attached it to the front of the 2×4.
  6. Build the Ladder (or buy a hanging ladder)
    1.  We started by using a tape measure to estimate the length of the ladder. It also helped us get a feel for what angle we wanted (or how steep the ladder should be).
    2. We started with a 30 degree angle and made a sharp corner at the top end of the ladder. Once we took it upstairs to test it out, we decided that it took up too much room and that the ladder needed to be more steep. Since we cut before we knew what we were doing, we had some spare wood that we used to fine-tune the angle. I recommend grabbing some scrap 2x4s to start with. Start with a 30 degree angle, hold it up to the loft, and see how it looks. If that sticks out to far, take another 10 degrees off of the angle (20 degrees) and try it out again. For us, about 15 degrees ended up being right.
    3. Once we had the top angle fine-tuned, we needed to trim off the excess on top. The notches on bottom aren’t necessary, but they look nice and make it easier to cut a 15 degree angle on a small miter saw. 
    4. For the step-width, we just put the two side rails in place and eye-balled the width and height between the steps. Just make sure you think about where the top step is going to lie and leave enough room up there. Once we know how many steps we needed and where they should go, we marked lines on the side rails, cut our wood, and then installed them with wood glue and 3″ finish nails (the finish nails weren’t quite strong enough and are why our ladder broke eventually).
  7. Sand and Paint
    1.  The ladder and the front facing loft board all needed to be sanded really well. I used a pretty heavy sanding pad at first and then switched to a finer one.
  8. Install Foam and Fabric
    1. Cut your foam to the size of the loft. We didn’t have enough foam to be a perfect fit, so we just slipped a few extra strips in on the side to make it work. 
    2. Cover the foam with fabric (kinda like you would a headboard) and staple the fabric into the plywood. If we were doing this again, I would probably make a fitted slipcover for the foam instead. Luke had that idea after the fact and I think it’s great. That way, you could take if off and wash it easily.
  9. Attach the Ladder and Patch 
    1. Attach the ladder to the front board.
    2. Add wood filler to the nails.
    3. Sand and paint.

How to make a ladder for a closet loft

We put the clothing bar up earlier in the loft build, but you could easily leave that until last. On the right side of the loft, we have shelving. That shelving was original to the house, but you could easily add that. More pictures of the finished loft can be found in the loft reveal post!

Like I mentioned, up above, we’ve used and LOVED this loft for quite a few years. All the kids that come over love hanging out up there and jumping from it. It definitely gets some use, but that’s the great thing about it. So, since we originally wrote this post, we’ve changed the flooring, upholstery and the ladder. The main part of the DIY loft though, hasn’t changed and is still working great for us.

p.s. If you love kid projects, we have a bunch of them. We painted a magnetic map wall, installed a car light switch, made a firetruck lamp and even installed a bucket and pulley on our play set.

    • Thanks Laura! It’s the perfect little spot and I’m hoping it will grow with him. Time will tell. Good luck getting the general contractor on board! =)

  8. This is amazing and well done! You now have me rethinking about my son’s closet. Thank you so much for the descriptive tutorial. I know those can be very time consuming to write. πŸ™‚

  9. Awesome post! Just came across your blog and I love your style! I’ve been sifting through tons of rustic cottage style DIY blogs and its refreshing to see someone with a similar design esthetic to mine.

    • Thanks so much Mandie! There are a ton of cottage style blogs out there. Have you happened across Brave New Home or Hello Lidy? Both of their styles mesh up as well.

    • Thank you! Actually that was a find at Habitat Restore. It was an old magazine rack for a doctor’s office. We gave it some paint and hung it up. It’s HUGE but we love it! Thank you!

  17. Oh, I’d love to have that Boy Cave as a kid, although having the top bunk was half-way there.

    Kids grow up fast, so some parents might want to tweak this design to make restoration easier. Just leave as much of the hardware in place as possible and save the materials.

  18. I love this, and the closet is nearly identical to my daughter’s. Can’t wait to start. Question for you, and I’m sorry if you’ve answered this elsewhere…when do you work on projects? Or more relevantly, what are your kids doing while you saw and sand and nail gun?

    • Thanks Kate! We only have one kiddo. He “helps” on projects that he can help on or plays with legos. We usually have one work night a week that he knows he has to entertain himself during. Usually from around 5:30-8pm on that night… it’s strictly work. It works for our family pretty well.

  20. It’s really great – my girls had something like this – they are born 11 years apart, My older daughter thought she had her own room, and the little one thought she was sharing!! Everyone was happy

  22. This is fantastic! I had this idea in mind but didn’t know where to begin. Thank you so much for all the details and how to. We are putting it in my sons closet and hope to make it in a way that we can convert it to a desk when he’s older. Great job!

  25. Super cute! I’d love to do this in my boys’ room! One thing I wanted to mention to you though is that when I was a kid, I had a foam pad on a piece of plywood on my bed and it molded pretty bad because there was no air circulation between the wood and foam. Slats rather than plywood would allow he foam to breathe.

  26. Hi! I know this has been out for a while, but I just found it. I’ve been trying to get my husband to help build something exactly like this for weeks (months? years?) and I think showing him this finally convinced him. He’s a carpenter with years of experience building houses, but we couldn’t quite agree on the project and I think he was over-thinking it. After seeing this, he agreed to do it this weekend! Thank you!
