Hacker help: Coffee to Dining convertible table?

Materials: unknown

Description: I'm looking to build a coffee/dining convertible table. Convertible furniture is becoming more appealing with smaller condos, but the prices are ridiculous. I think we can do better.

What I'm looking to accomplish is a table like this one (pics above).

Any initial thoughts are welcome!
