Convert space under a loft bed into storage and a desktop space. Simple plans even have a spot to hide a cpu!

Works with the loft bed and the loft bed big bookcase plans


Today, we are going to finish up the loft bed plans by adding two small bookcases and a desktop.  I actually designed this plans so that it's really one small bookcase, with a longer top on one of the bookcases.

We already have plans for the loft bed and the large bookcase, so these smaller bookcases are the final pieces to the loft bed collection.

General Instructions

Work on a clean level surface. Check for square and use good straight boards. Predrill all screw holes with a countersink bit. Be safe and have fun!


Step 1

Build the box as shown above using 2″ screws and glue. Build one as shown above, and the other without the top attached.

Step 2

Attach the footer as shown above, using 2″ screws and glue. Inset the footers 1/2″ and also keep the top edges flush. The bottom edge will be just shy of meeting the ground.

Step 3

Attach the backs to the bookcases. You may need to wait to attach the top in the next step to the second bookcase before adding the backs. Make sure you fasten to the shelves too. Use glue and 1 1/4″ nails.

Step 4

Attach the large desktop to the top of the second bookcase, and the legs too. Use 2″ screws and glue.

Trying to decide if I should shorten up the bookcases and the desk if I'm going to take 8" off the loft due to a lower ceiling. Which would be better, less headroom or a little lower desk? Book cases will be fine either way, it's just sitting at the desk doing homework comfortably that I worry about?

Hey, i am a teenage girl and i found it easy (with a little help from dad) to build this loft bed.
I added a large mirror to the wall behind and put fairy lights around it so that is is like a really cool vanity. I also turned one of the bookshelves into a chest of drwaers so that i can store my makeup there! I added plywood in the shape of giant polkadots, varying in sized to make it a little prettier and so that it would fit in with my overall colour scheme. Thanks so much, my room is only 250cm by 210cm so this made a big difference to the space i have in there. Very effective for saving space, i would reccomend this for any teens room.

randomlittlelady, I would love to see a picture of your bed. This is exactly what I plan to do for my 12-year old daughter's room and would love to see one with an actual vanity underneath. Could you please post a picture? It sounds great! Congrats!

Does this plan have any dimentiions change if I was building the loft bed as a full instead of a twin? My daughter is the oldes but as the only girl with two brothers she gets the smallest bedroom so this helps alot with space.
