I stumbled upon Ana’s blog about a year ago. Since, like many of you, I have become addicted to building. I loved her playhouse loft bed and thought it would be perfect for my almost 5 year old for her birthday. As I thought about it, though, I wanted to put my own spin on it that would make it more “her”. So I decided to make a castle loft bed. I took the plans of Ana’s and tweeked them to add some towers and a slide. I have since been asked multiple times for the plans, of which I had none. So I decided to tackle learning Sketchup and try making some plans. Please beware I am still learning Sketchup and am far from perfect in the way it looks, but hopefully it will be enough for those who want to copy me ☺ I built this entire thing with my circular saw and a guide to make the long cuts and a miter saw. Obviously it would be easier to use a table saw. I would recommend cutting as you go in case any of your measurements are slightly different than mine. Also, since finishing was going to take so long, I decided to use Melamine plywood that was already white, since I wanted it to end up being white. Because of this decision everything except for the railings and bed supports I cut from the plywood. You might decide to use regular plywood and use normal boards for things like the stairs. If you do, you’ll just have to adjust some of the measurements accordingly. Looking back, I don’t know if I would use Melamine plywood again. Sure, finishing was a ton easier, but if the plywood chipped at all or the plywood got nicked, it is harder to fix with the melamine finish. Ok, on to the plans…


Thank you Ana for all you do! Creating these plans really gave me an appreciation for all the hard work you do!

Kreg Jig
Circular Saw
Miter Saw
General Instructions

Please read through the entire plan and all comments before beginning this project. It is also advisable to review the Getting Started Section. Take all necessary precautions to build safely and smartly. Work on a clean level surface, free of imperfections or debris. Always use straight boards. Check for square after each step. Always predrill holes before attaching with screws. Use glue with finish nails for a stronger hold. Wipe excess glue off bare wood for stained projects, as dried glue will not take stain. Be safe, have fun, and ask for help if you need it. Good luck!


Step 1

As mentioned above, I recommend cutting as you go. Here is an approximate look at how you can cut the plywood to get the above pieces.

Step 2

I worked in sections. I made the front section first, then the slide sections, then the stairs. Each section will stand up on it’s own (and is very heavy). Then, I put them all together and added the railings and bed slats.

Connect the sides (10” wide) of the tower to the front of the towers (11” & 18”). I used a Kreg jig with 1-1/4” screws to connect them. The sides are connected to the back of the tower fronts, so that the total width of the towers are 11” and 18”.

Step 3

Working on the front center, cut out the door. I made the door 22” wide and 38” high in the middle. Draw with pencil first and then cut out with a jigsaw. Connect the middle to the two towers so that the back of the middle is flush with the back of the two towers.

Step 4

I wanted the larger tower to be a little window seat. To cut the window, I measured up 26” from the bottom. Then, I made each of the windows 4 ½ x 7 ½ with 1 inch in between. I rounded the top windows for looks. Again, I drew on the windows with pencil, used a drill in the corners to get started, and cut out with a jigsaw. You might want to adjust the height according to how tall your child is.

Step 5

Step 6

Add the 2 1/4 “ piece of plywood onto the end. This is to make it long enough to fit the twin mattress. You can forego this and instead make a tower or the center piece wider, but I liked how this made the front and slide connect better.

Step 7

Next, the slide. Probably the hardest part of the entire bed for me. Trying to figure out how to make it so that it wasn’t too fast or too slow. The dimensions I give you are for a fairly fast slide. My 3 year old does great, but it might be too fast for a two year old. If you want it slower, just drop the same distance down, but make the side a little longer to make the slope a little slower.

The dimensions I give you are for a slide that is wide enough for kids and a tight fit for most adults. If you plan on going down the slide a lot yourself, you may want to make the slide wider.

Take the two 56.5” pieces of plywood for the two sides and the piece 17 ¼” for the back. This part gets a little tricky, because you can put the sides and back together now, but it is narrow enough it makes it hard to work inside that area. I would suggest putting some of the supports on first and then putting it all together.

Take the 15 3/4 “ wide by 41 1/2” piece and attach this to a side 12 ¼ “ from the back. This will help support the slide platform.

Step 8

Get your 1x2 boards that are 11 ½”, 12 ¼” and 15 3/4” long. Connect the 15.75” long one to the back of the slide, with 3/4 “ on each side (on the side already attached, it will be right up against the side), with the top of the board being 7 ½” from the top. Then attach each of the 11 ½” to the sides, also 7 ½” from the top, inset from the back by ¾”. The 12 ¼” pieces go along the floor, flush with the back of the sides to give added support between the back and the platform support.

Step 9

Attach the 7 5/8” by 15 ¾” wide piece to one of the sides, flush with the front edge. This will be the bottom support for the slide.

Step 10

Now, draw a line of where the slide will sit. Go from the front of the slide support to the front of the bottom support. Directly under this is where you will put the 1x2 slide supports on each side. The 1x2 does not have to go the entire length – I left an inch or so on each end so that I didn’t have to mess with cutting the ends at the right angle. Attach this to each of the sides.

Step 11

Finally, put all the sides together and attach.

Step 12

This step isn’t essential, but just for looks. I wanted to leave the sides of the slide open as much as possible. On the outer side of the slide, starting at the front edge of the platform I went down 2 ½”. At the bottom of the slide, I went up 13 1/2” and made a mark. I drew a straight line between these two marks and cut with my jigsaw.

On the inside wall of the slide, I measured up the same 13 1/2” at the bottom of the slide. Then, I determined where the edge of the bed would be, 40 ¾” from the back of the side. I drew a line straight down for 23”, then drew a line from this point to the front of the slide and made two straight cuts.

Step 13

Not wanting all that space under the slide to go to waste, I cut out underneath to make two closets. I again just drew on and cut out with the jigsaw.

Step 14

Now time for the platform and slide! Take the piece 15 ¾” by 13” for the platform and attach to the supports.

Step 15

Then comes the slide. This is the one time when using melamine plywood really helped out. It is very slick, even once painted (at least after the one coat I put on). I would recommend using it for this piece. You can always get a piece in the section of the box store that sells closeting products if you want just one board, although you may have to adjust the width of the slide accordingly. This piece is 15 ¾” wide by at least 55 3/8” long. I made mine a little long (57”) because I liked the thought of it hanging off the end a little and wanted to be able to cut some off to make the end of the slide straight up and down.

Another tricky part for me was at the top of the slide. The top of the slide needs to be cut at an angle so that it fits snugly with the platform. I laid the slide on the supports and estimated the angle to cut it at. Then I cut it and laid it on the platform again until I was happy with the fit. Finally, attach the slide to the supports. I just countersinked some screws and screwed the slide directly into the supports underneath.

Step 16

The stairs. Attach the sides to the back, just like the slide sides. It is wide enough that you can put both sides on first if you want, although it is a little tight to work if you do that. Then, attach the 1x2 step supports on both sides, at the top and bottom of each step, as shown in the diagram. Also at this stage attach the larger 29.25”, 19.25”, and 9.25” stair supports in.

Step 17

Attach supports to sides, then attach steps to the top of the supports. At this point if you want to cut off some extra from the outside of the stairs, I recommend measuring up approx. 29” from the bottom of the front of the stairs and measuring 16” from the back of the top. Draw a line between these and cut a straight line. If you want to finish this edge off, I used a 1x2 on it’s side to make a sort of railing.

Step 18

Cut out under the stairs, just like under the slide, to make a couple of closets.

Step 19

Attach all the pieces together. Then, make the railing. Use 1x4’s for the top and bottom of the railings with 1x2’s cut at 11 ½” long for the up and down part of the railings. Space evenly with 3” between slats. Note: Especially on the back, please cut length to exact measurement, as yours may differ slightly!

Stairs outer edge: Cut 1x4’s to 15 7/8”, use 4 slats
Stairs inner edge: 1x4’s to 25”, use 6 slats
Front center: 1x4’s to 47”, use 10 slats
Front right: 1x4 to 2 ¼”, use 1 slat
Slide inner side: 1 x 4 to 25 ½”, use 6 slats
Slide outer side: 1 x 4 to 13 1/16”, use 3 slats
Back: 1 x 4 to 115 ¾”, use 26 slats

I used 1x3 instead of 1x2 at some of the intersections of pieces, just a preference.
Attach all the slats to the bed. Since the railing against the wall supports the mattress, I then used bolts to attach the top railing to studs in the wall. I did this about four times across the bed and it really helped with the support and to keep the railing from being pulled away from the wall.

Also, for the slide inner edge and the stairs inner edge, there wasn't as much support as I wanted. So, I bought a couple of L brackets (used to put up shelvings and such) and attached one to each set of railings, with the other end of the L bracket being attached to the under bed slats.

Step 20

Cut two 2x2s to 77 ½” long. Attach one to the front of the back railing, flush with the bottom using 2” screws and glue.

Step 21

Attach other 2x2 inside of the front of the bed, flush with the bottom of the front railing.

Step 22

Mattress support slats. Cut 1x3s to 40” long. I wanted there to be a lot of support since us adults wanted to be able to be up on the bed, so I placed them every 2 1/2” apart. Use approximately 16 slats, depending on your desire of support. Attach to the 2x2s.

Step 23

Tower decorations.
Cut 1x4s to the following legths: four at 10 3/4”, one at 12 1/2”, and one at 19 ½”. Attach these to the top, outside of the tower, about half (1 ¾”) sticking up above the tower.

Step 24

Cut 1/8” plywood to be 6” wide. Out of this, cut one at 11 1/8, one at 18” and four at approx. 10” (measure to get exactly how deep you want these to be). Then, cut the up and down parts. I found that cutting down 3”, over 2 ½” or 3”, up 3”, over 2 ½” or 3”, etc. was a good pattern, centering these cuts over the piece of plywood. So, on the front, I might go in from the edge 1 ½”, then start the pattern, ending up with 1 ½” left on the other end. Just play with it and draw it on to make sure you like the results. Then either use your jigsaw or just a knife to cut out.

Attach these behind the 1x4’s and they will sit on top of the original tower. Nail to the 1x4’s.

Step 25

Other finishing touches:

Apply edging to raw edges.

See picture of my finished project. I used more 1/8” plywood to make a point on top of the one tower. I used tape and glue to put it together.

I wanted to do something over the rails in the front. I again used 1/8” plywood, cut it to an overall size of 27” high by 24” wide, then used a jigsaw to shape it the way I wanted. Paint and screw to the rails. Mine goes above the rails by 2 ½”. If you do that, I suggest putting a 1x3 24” wide behind it to keep the top from getting broken (I didn’t do this at first and part of it got broken right away).

I wanted a more finished bottom edge, so I purchased some molding, painted it before installing, then cut using a miter saw and nailed to the bottom of the front of the bed. I really liked the finishing look it gave.

Finally, I purchased wall decals so that it really had that princess touch!

Finishing Instructions
Preparation Instructions
Fill all holes with wood filler and let dry. Apply additional coats of wood filler as needed. When wood filler is completely dry, sand the project in the direction of the wood grain with 120 grit sandpaper. Vacuum sanded project to remove sanding residue. Remove all sanding residue on work surfaces as well. Wipe project clean with damp cloth.

It is always recommended to apply a test coat on a hidden area or scrap piece to ensure color evenness and adhesion. Use primer or wood conditioner as needed.

This is wonderful!

I am planning a princess loft bed for my 4 year old daughter - for practical reasons, and for her... :) She has limited space... She loves your design and subsequent photos!

I am very familiar to Sketchup, and have already built her room to scale, including several different beds... Then I stumbled upon your design!

This being said, is it possible that you might have the .skp file available? I would LOVE to just "drop it in" her room, as it were, and see what it does to the space.

Thanks for such great inspiration!

My son is 3 and he loves this bed! Would I be able to order this already made from you? If yes, can you provide the cost and time-frame? It would be an awesome Christmas gift. I've been saving for the $$ for this moment! It's time to get him a toddler bed and I'm super excited!. :)

What are the finished dimensions on this bed? I'd hate to try to build it and have it not fit! Thank you!

thanks for the plans, Household 6 has given the order that I start working on this for our daughter....I'm thinking of using 1/2 " though to save some weight since moving will be mandatory every few years.

To everyone asking about final dimensions; she has been kind enough to repost those several times in the comment replies....just look through them but here you go again.

"It is 10' 5/8" long, 5'7 3/6" tall (at the rails, slightly higher for the tower), and 4' 9 1/4" deep at the slide, which sticks out the farthest. I hope this helps!"

I LOVE your Castle Bed! I want to make this for my daughters. Any idea of how you could make the cones that sit on top of the turrets? I saw some pics of castle beds that have the cones and I just think it adds a finishing touch :))

Hey nice work. I'm thinking about tackling this one. I have a few quick questions:
So you only used 3 types of saws?
What would you estimate for the cost of materials?
Could a bottom bunk be incorporated in this design?
About how many hours from start to finish?
Thank you so much in advance..


Sun, 03/10/2013 - 14:36

Do you by any chance know "about" what the finished product weights? We are in the military and are limited on weight each time we move.

Thank you for putting the finished dimensions on here... that's a big concern also :)

10' 5/8" long
5'7 3/6" tall (at the rails, slightly higher for the tower)
4' 9 1/4" deep at the slide, which sticks out the farthest

One last question... since we will be moving (multiple times) before my daughter outgrows this... if I leave off using the wood glue and the wood filler (over the screw holes?), then it should be pretty simple to disassemble and move??

I plan to make this (with my husband help) for my 4 y/o daughter. We want to paint it grey like a castle with pink and purple flowers and green vines climbing the walls. For the Coat of Arms I would love to be able to sew a banner using our familys actual coat of arms... Too bad the colors are not pink and purple :)


Sat, 06/29/2013 - 15:03

I cannot tell by the plans or the instructions how the railing should be mounted to the walls.

I looks like they are attached flushed to the walls. Did you attached by screens through the 1x4 into the wall edges?



Sat, 11/02/2013 - 20:36

I built this bed in 2012 and had to move this fall. If I can make any suggestion it is do not fill the holes. I did and it took me a bit to find them and clean them out. I separated it into five pieces and they were heavy, but movable with some young men to lend a hand

The bed is now sitting in my garage as it does not fit in the new house.

it needs a new home, but ya gotta have the room for it.…


Tue, 09/17/2013 - 07:49

I really want to build this for my two girls. I may have more questions if that is okay but my first one is. How did you attach the two towers to the front panel?


Fri, 11/22/2013 - 14:05

Can you confirm that the clearance under the bed is 48 inches? It's not explicitly stated anywhere, but I've read through the directions a dozen times and I think 48 inches is correct. I want to make a modified version without the facade to fit above a bookcase/bed that is 47.5 inches tall. Thanks!

i am from germany and would love building this bed. 

Could you be so kind explaining me, for example, what does 3/4" plywood and 1x3 mean?

Thanks a lot.

I was wondering if anyone could tell me if this would be possible to do with a queen size bed underneath, what changes would have to be made to the plans? I have someone who does great building with exact plans and would love this for my twins


Thu, 07/09/2015 - 04:15

Hi, I will try to build this one for my daughter. But I can't say I totally understood the shopping list. Could you please give the shopping list in metric system. If I can get that, I belive I can build it. I can see that "the 6 sheets" should be 18mm. But I couldn't understand this one (11-1x2 at 8') . Thanks for your help.


Tue, 07/28/2015 - 06:56


What does under the ("Shopping list" title) 11-1*2 at 8' mean? I dont live in US so I'm not sure how to interpret that. Is is 11 pieces od 1 inch*2 inch at 8 inch length?


Thu, 08/06/2015 - 11:21

Hi!  I am currently building this for my son, thank you for the plans!  Quick question, may be obvious, but you say put three did you do that?  Did you use a kreg jig?  Thanks!!!  Heather

I bet a lot of us would love to help, but I'm not sure which step you're referring to? If it's step 2 (that's my guess?), you could either use a kreg jig on the side pieces to screw into the front, or you could screw through the front, countersinking your screws so they can be filled later. 


Wed, 12/27/2017 - 09:30

Thank you so much for the plans! This was my first build ever and the plans were very easy to follow. It came out way better than I expected. I did, however, make some changes to personalize it but the base is your plan. My daughter loves it!
