An Ikea Expedit Bookcase Turned Hamster Mansion
Pet Projects

When I was a freshman in high school I had a hamster. It was a bittersweet experience as my hamster lived only a few months and when I found his cold, hard body one morning it took weeks for me to get over his death. To make matter worse, no one at school understood why I was so upset about a hamster. I got looks of pity when my eyes welled up, but not of the sympathetic kind.
During my little hammie’s short life, he lived a simple one in a large bi-level metal cage. There was nothing warm or comforting about the place. It was more like a prison than a home. I regret not giving him a proper pad to roam in, but back then choices were limited. Yes he had a running wheel and tons of bedding to burrow under, but other than that life chez Zjawinski was a total bore. The idea of building a unique and custom made hamster habitat hadn’t even crossed my mind, but thanks to Flickr many hamster owners have been able to share and inspire each other with photos of their DIY palaces.
One of our most popular Pet Projects on Pawesome has been Tina‘s amazing Ikea hacked home for her dwarf hamsters. It’s since inspired many other hamster owners to hack Ikea’s Expedit bookcase into a hamster paradise. One example is Katja, who turned one Expedit into a three-story mansion for her little man Fred. Details on the remodel after the jump.

The framework of Fred’s house is based on an Ikea Expedit 5-by-5 bookshelf. Katja removed the dividers on two of the floors in order to create large spaces for Fred to run around in. The sections of the bookcase that are intended for Fred are reinforced by backs that feature cutouts for vents to allow for proper ventilation. Top to botton glass doors are installed on the fronts of all of Fred’s cubes, which keeps Fred safely inside, but allows Katja easy access for cleaning.

The top floor spans the entire width of the case and features plantation soil, made from coconut shells. “I wanted the whole area to be darker as a contrast to the sand area down below,” she writes on her Flickr page. She placed hemp mats around the stair openings in order to catch loose soil so as not to contaminate the floors below. The two outer boxes on the second floor act as gateways to the bottom, which features a box filled with wood shavings and hay for Fred to burrow in, along with a sandy beach to groom himself in.

The ladders that connect floors are made using pieces of natural wood, while sections of hemp cover the floors. Katja used a simple glass cooking dish to fill with cork for Fred to play in. She also built a natural water bottle holder with dowels, cork, roots of dandelions, and willow branches. A small dish below the bottle catches any drops that miss Fred’s mouth.
A dish on the top floor is filled with maize cob granulate in which Fred can dig for food. A willow bridge directs Fred from plantation soil to the dish. A small house on the top floor includes a small litter box filled with sand for when Fred needs to tuck away for private moments. Katja installed four-inch tall glass panels within the top section to keep soil from getting stuck in the E-profiles of the front glass doors.

The lower level includes a sand floor filled with chinchilla sand, which Fred uses for grooming. A 6-inch glass panel at the front keeps sand in place. Katja repurposed an Ikea Asker kitchen container into a small cave for Fred to hang out in. Lastly, Katja installed diode-lights to the upper level and the sand area. She can switch between between white, red and blue light. Hamsters are red blind, which allows Katja to spy on Fred without disturbing him, while blue light imitates moonlight.
It’s projects like these that make me want to try hamster life again. Thanks so much for sharing Katja!

[...] Katja’s hamster Fred has a home to die for, for a hamster. Katja converted an Ikea Expedit bookcase into a multi-level hamster home featuring a different room for each activity. Fred has a large room for running, stairs and ladders to traverse, a room to burrow in, a room to take a dust bath in, a room to eat in, variable lighting, and plenty of places in which to explore and play. See more pictures and find out how it was done at Pawesome. Link [...]

Absolutely gorgeous. This is prompting some amazing ideas for a new chinchilla habitat for our kids … :)
yeah right. I’ve had hamsters and you would have a full time job cleaning this.
Hamsters will urinate is on spot (where?), but will “poop’ anywhere and everywhere.
However, it does look nice…a lucky hamster.
Awww…no action shots of this very, VERY lucky hamster enjoying his ultra-luxurious accommodations? :-(
No. He died a week after finishing the house. :-(
Oh no! So sorry Katja!
Hi! Im a hamster owner too for 13 years now and this is absolutely the most beautiful hamster habitat I have ever seen although there are couple things u did wrong…and could be the reason of Fred’s sudden death.
1. NEVER EVER use maize cob bedding because it builds up this type of fungus / mold that’s not visible to our eyes and it could kill your hamster in a heartbeat.
2. Pebbles / small rocks can be dangerous to hamsters because they tend to collect and collect and it could choke them when put in their cheek pouch.
3. This one Im not too sure, according to my friend who’s a vet she said that some hamsters are allergic to chinchilla sand/dust bath and it could cause a health problem.
4. My cousin and my other 2 friends used soil for their hamster too and not too long they died, Im guessing it’s something to do with the soil.
5. NOT all plants are good for hamsters some could get them sick some could kill them.
That is all I hope this helped for further reference. Good luck for your next hamster hope all is well.
Hi epicmochi, thanks for sharing your experience!
I wanna add some things from my view:
To your first point: I never heard of problems like this, in Germany many people use this and nobody had problems with it (at least I didn’t hear about it). Could you tell my more about it?
I think with the small rocks you mean the stone house? Those stones can’t be collected by him as they are glued together. No hamster will get through this.
It’s interesting that your friend as a vet says that hamsters can be allergic to the chin sand. To be honest I never heard of this and I am really curious, what sand she would prefer. Because hamster need sand for grooming and this sand has no particles in it, that would harm the hamster (like sand for birds)
I use the soil and I know some people who use it longer than me and no hamster had died of the soil. I think the hamster died on something else (did they dried the soil? It’s not good if you use it wet).
And your last point. I don’t think you are right to say “Don’t use ANY plants”. Hamsters even need some as food. But you are right, the special plant you see on the photos can be dangerous. These plants accumulate harmful substances from the air, so I would not recommend to use them more then a couple of weeks. I already changed them into self planted wheat (but Fred hadn’t taste it yet). Those plants are really great as food and as decoration.
@epimochi: some disagreement on that:
re: 1. yes, corn cob bedding is unsuitable to very damp climates like in Singapore or Florida. In a country like Germany, though, it is perfectly fine and a standard accessory among hamster lovers. All the forums and sites over here recommend it and nobody has a problem with it. In damp climates of course it’s best avoided.
2. was already answered.
re: 3. what your vet friend meant is chinchilla DUST, not SAND. Dust ist supposed to be bad for their respiratory tract but sand is fine. Chinchilla dust is not even available in Germany (only sand), so no danger there.
re: 4. that really depends on the soil and on the condition of the soil. If you offer something that’s really wet your hamster might catch a cold or pneumonia. Other soils become really dusty when too dry which would be bad for their respiratory system. These are situations to avoid. And of course you should not use soil that contains fertilizer. The coconut soil mentioned is sold as terrarium soil and 100% fertilizer-free. As long as you don’t use it dripping wet this would be perfectly ok.
re: 5. yes, you have to be a bit careful when choosing plants. Your safest choice is organic grown cat’s grass. That’s also one of the cheapest options – just replace it when the hamster eats it.
Well, thanks for planting such a lie.
Fred moved in on February, 12th and is still alive. If you want to see a pic of him, you can do this on my Flickrpage http://www.flickr.com/photos/xscrattyx/sets/72157625912653471/
If you have any questions, you can ask himself at his Facebookaccount ;) His name is “Fred Zwerg” (Zwerg means dwarf in german)
So.. greetings from Germany from Fred and me :)
Hey – you can see them on my flickrpage – the time I took the photos (and Sonia wrote this article) Fred hadn’t moved in :)

I own 3 mice and this is an awesome idea! My mice would have a blast if I built them an Ikea mouse habitat such as this. Love it!
I’m a friend of Katja and have to say, that Fred is still alive and super happy in his mansion. Last weekend Fred dig his first tunnels into the box with wood shavings. Very cool to see him digging through the glas front!
The place he likes most have to be the stone house. Most time he sleeps here.
I wonder about people who are talking shit about his death an, especially if they do not know him in real life. Sorry meklonhead, but you don’t know anything ’bout Fred. So don’t open your mouth, until you have to say anything that make sense!

I wish I was a hamster when I see this!
That thing is possibly the most awesome hamster houser I ever saw. Makes my hamster’s cage look like a prizon cell by comparison.
… what about formaldehyde used in IKEA products? Not safe for us, maybe can it kill pets?

First I want to say this is a great idea and setup. I’ve been looking for clever ways to incorporate my reptile cages into my home decor. I just have a question, what type of wood did you use to re-inforce the back?
That’s awesome! It’s like a hamster haven!
Excellent setup, the Waldorf of hamster cages.
