General Instructions

Make sure you measure your space before building. The bed parts can be assembled in the room, so doorways aren’t as big of an issue.


Step 1

Build the Top Bunk

You will need to build a top bunk made up of two footboards. Simple twin size bunk plans are here. When you add the slats to the headers, start in the center and work your way out. If the spacers do not fit tight at the end spacers, don’t despair. Simpy cut a piece of 1×6 leftover from the header to the exact dimension and use it as the spacer instead of the 1×3 spacer.

Step 2

Build the Bottom Bunk For the bottom bunk, you will need to build the Full Size Simple bed, but this time, build two headboards and no footboards.

Step 3

Assembly Measure the location of the top bunk and mark it on the headers for the bottom bunk. Find the center of the marks and drill a 1″ hole, 3″ deep. Then find the center of the bottom of the legs on the top bunk and drill a 1″ hole, 3″ deep. Use 6″ metal headless bolts or hardwood dowels to hold the bunks together through the drilled holes.

Step 4

Ladder For the ladder, cut two 2x4s 64″ long, with both ends cut at 25 degrees off square parallel to each other. Then on the top edge, mark the top edge in 1 1/2″ from the front top corner. Use a square to mark a line perpendicular to the top cut downward. Cut this line off. These are your ladder sides. Measure and mark the ladder sides and screw the rungs to the ladder sides with 2″ screws and glue. The ladder can be attached with metal brackets or by screwing from the inside of the side rails of the top bunk. Guardrail plans area also available in the Twin Simple Bunk Plans.

Lindsey, I don't see why this wouldn't work - just make sure your slat system is properly done - perhaps with a center support, so the top bunk is adequately supported. The ladder could also have less of an angle in that case too (this ladder is made to fit the wider bottom bunk).

Oh my goodness! How on earth did I miss the laundry basket dresser?!Seriously, I have a baaaaaad problem with moving clothes from the laundry basket to the dresser. With that dresser, I wouldn’t have to bother and no one woud have to be bothered by my clothes living permanently in a laundry basket. And thank you for such simple plans for making the twin over full bunk beds. Happy New Year!

Hi Ana...I'm one of the ones that has been waiting for this. Our upstairs bedroom is shared by our two boys. It has eaves that cut into our ceiling height, but we have a full height in the center. We're planning to switch the ladder to the other side of the bed, perhaps with less of an angle, so the "full" part of the lower bunk will tuck in under where the ceiling starts to eave. Hope that makes sense. It will be such a huge space saver :)

Ana -

You are just 10 kinds of amazing, I want you to know that! I love reading your site and though I haven't built a thing yet (for shame, I know!) I am amazed every time I read a new post. I get super excited over every new plan and I want to build stuff so desperately! Gotta make some room in that garage for me to do so... haha

But I just wanted to say that I was so excited about your reasons for building, esp. #6. I hadn't thought about just how green building is... thank you for showing me another reason for wanting to build! :)

I want to build the bunk beds instead of buying a set mostly because I want a sturdy bed and cost. One additional thing I would like to do is in place of the ladder have the stairs at the end of the bed with a built in dresser. Any help on this would be greatly appreciated.

Just a side note. I was directed toward your blog and I have to say you are one amazing woman!!! I love coming back to see what is new and get more ideas.

So, I'll admit, I didn't really read this post, since I already made bunk beds. But then all of the sudden I started getting all kinds of comments on my blog, and realized they were referrals from you. I am tickled pink! Thank you so much Ana for featuring my room!

Keep it up - your site is the best!
