Tank size

[TGC]

Ok so I spoke to my dad and i might build a new stand with him this weekend that will be a good size for a tank that is 36L x 18W X ??height.

So i have a few questions..

Firstly, what type of aquarium/terrarium should i look at?
I want this for display purposes in my bedroom, so i wont use plastic containers.

I already have all the stuff for my snake in his current tank (an exo terra 24x18x18) but with this next size up, i may need a new UTH cable or mat.. not a big deal.

Anyways if anyone with a similar size configuration could tell me a proper height and What size heating things will be needed. Also brand names or types of stores to buy a terrarium would also be helpful for me. Ideally, i'd like to spend as little as possible, but I do want to make sure i can get a secure lid that is also easy to open and get into.

Thanks
