We wanted to add some storage under the loft bed - since that's why you do a loft bed, right?  To increase the useable space in the room.



And you could even hide a CPU tower back there.  


Today we will focus on the big bookcase.  You can omit the bottom supports on the loft bed if you are going to be attaching the bookcase.  The bookcase will give you all the support that you need.


Overall Dimensions are shown above.  What we are building today is a simple bookcase that could be used without the loft bed.  Composition is 1x12 boards with 1x2 and 1x3 trim and 1/4" plywood back.  This bookcase can be made from solid wood for a natural stain finish.

General Instructions

Since we essentially build chop-screw-paint, the instructions are pretty simple. Work on a clean level surface with good straight boards. Check for square after each step. Use self-tapping screws or pre-drill and countersink all of your screws. Be safe and have fun!


Step 1

This bed was very much inpsired by Pottery Barn Teen’s Sleep and Study Loft. According to Pottery Barn Teen, their bed was made of:

Frame: Pine
Panels: MDF with veneers
Slats: Pine
Drawer Box: Plywood
Shelves: MDF with veneers
Knobs: Pine
Ladder: Pine

This is also the most economical materials to buy.

Step 2

Build the loft bed, but you can skip the bottom support on the side that this bookshelf will be installed. Loft bed plans can be found here. This bookshelf is designed for a twin bed. You can alter the bed by cutting all shelves and trim to 51″ long, assuming that your full size bed mattress measures 54″ wide.

Step 3

Use the 1x12s to build the box as shown above. It is always recommended to measure and mark your joints on both sides of the joint so you know where to line the board up and where to screw. If you have a Kreg Jig™, you can drill pocket holes on the undersides of the shelves and attach the shelves to the sides. If not, 2″ wood screws and glue will keep everything in place. Don’t forget, we will also be adding a back that will hold the shelves in place and shelf trim.

Step 4

Attach yoru footer as shown above. If you are using a Kreg Jig™, simple drill your pocket holes on the ends of the 1×3 and attach to the sides. Otherwise follow the instructions above.

Step 5

Step 6

Just like the footer, attach the top shelf trim as shown above. Use glue and 2″ screws.

Step 7

If you know these shelves are going to be taking some abuse, it would be a good idea to cut scrap pieces of 1x2s and fasten to the sides of the bookshelf under the top shelves. This will keep the top shelves from ever moving. The bottom shelf is attached through the grain to the back, and they are not going anywhere. But the top shelves are attached through the end grain, and a support like the one pictured above would add considerable strength to the shelves (and you already have the scraps laying around!). The 1×2 will be 9″ long if you inset your shelf trim pieces 1/2″.

Step 8

Screw the bookshelf to the sides of the legs to stiffen up the loft bed. The bookshelf replaces the bottom support, so you need something to keep the loft bed legs square.

Finishing Instructions
Preparation Instructions
Fill any holes with wood filler. Let dry completely. Sand with a coarse sandpaper and work your way to fine. Prime and paint as desired.

Love the original loft bed and love this room within a room design even more. What an efficient use of space. It’s amazing the way you break these unwieldy-looking projects into small we-can-do-it bites.

I was hoping you would add this to the loft bed! My daughter has been asking for this bed from pbteen for over a year!

While the original bed was too high for my girls (we opted for the fort bed) I am really excited by the modifications because this bed is now perfect for my niece. My sister will be thrilled!

i love it. my little guy's bedroom is 8'x8'. tiny. and his windows are tall & start really low to the ground, so there is only one place for his bed. when our big kids lived in this room (at various times), we had a "cargo furniture" loft bed with dresser 7 desk underneath. BUT! that furniture is SO massive and the ceilings are SO low. a lower loft bed is a great idea!

What a great addition to the loft! My husband and I are planning on building TWO of your loft beds this year. Two kids, one small room, lots of toys... we were so happy to find the plans for the loft bed! Of course... we'll be building the kids' beds *after* we build our queen size storage bed ;-)

I adore this bed! My 7-year old stepdaughter's room is teeny tiny, so this would be a perfect use of space. My only reservation is wondering whether this will be considered a "baby bed" in a few years. Anyone have teenagers that use/want a bed like this?
