What tools and/or supplies are required to put it together?

Craft knife, small scissors, tweezers is a must! I use fast grab tacky glue, it adheres quickly like rubber, double sided tape and glue sticks (it allows your wallpaper and floors to go on smooth, no lumpiness) and a ruler, clear really works wonders, oh and some crazy glue. I’ve completed over 40 kits, these are my bare necessities I can’t go without and I learned through my own trial and error.

Do you need to purchase any other tools or glue to assemble or is everything included?

No. It’s all included, even tweezers.

what other supplies do you need?

Everything you need comes with the kit. But...I've put together 5 of these and I've learned there are a few things you can buy yourself that makes things a lot easier. Buy some Aleene's Fast Grab Tacky Glue. It sets up really fast, so much better than the glue they provide. Some small and medium binder clips. Those can be used to hold small pieces together while they dry. Some extra white tempera paint. They don't give you enough to get good coats of paint on the walls. A pair of needle nose and small wire cutter comes in handy, too. And finally, an x-acto knife for cutting out tiny pieces of paper.
