The IKEA Detolf is a popular choice of cages for those with some DIY skills. It is actually a glass display case that is placed on its side to provide a large habitat.
The Detolf actually provides the largest amount of unbroken floor space (in terms of square inches) of any cage on the market.
On its side, the cage is about 64" wide, 17" tall, and 14" deep. This means you will need a little over 5 square feet to keep the cage (5 feet long and 1 foot + 2 inches out from the wall). It is actually fairly easy to find a place for as it can rest on top of all kinds of furniture that is probably already in your home.
Besides the cage itself, you will need something for it to rest on safely. The furniture should fully support the glass bottom, otherwise you risk the cage falling or cracking. The Hemnes dresser from IKEA holds it very well, as does the IKEA Kallax series (which comes in cute colors!). Some other options from Ikea include 4 or 5 small Lack Tables, and the Nordli 8-drawer chest. Of course, if you own furniture that matches the measurements of the cage--such as a dresser, a table, or even a console piano--you can use that too.
Not at all! It will be a little bit of a different process than other cages though. You will scoop the bedding out of the cage using either your hands or a dustpan, and put it into a trash can or bag. Then just toss and refill! There are lots of videos on youtube (like this and this) to help you with your new cage!
If you need to wipe down the glass, use a safe cleaner such as vinegar and then wipe well with a wet cloth or paper towel and dry. The outside of the glass can be cleaned with natural glass cleaner--equal parts vinegar, water, and rubbing alcohol.
You have a few options!
You can make a lid out of wood and hardware cloth (great tutorial here)
Or, for Syrian hamsters, you can grab a wire shelf (this one is recommended) and cut it down to 64" using a hacksaw. If you go with this route, we recommend finding a secondary way to secure the shelving down for ambitious would-be escape artists.
Look at the lids in the photos below. There are examples of both types!
