Step inside our M-Velope and you can! It's a massively cool 15-foot high by 14-foot wide by 17-foot deep creation of functional art built with a steel frame. All its hinged wood panel frames open, move, and close at your whim. Michael Jantzen, an internationally famous architectural pioneer/artist, thought it up and he is crafting just 10 structures for us exclusively. He's a leader in rethinking how we live, and he's been green since '71. He builds each M-Velope with new Accoya® wood products that are durable and completely sustainable. (via Neiman Marcus)

Oh my god, I love this! It's like the coolest 'fort' for grown ups! A modular structure that is portable and can be an office, studio, hideout, whatever you want.

if, of course, you have 100,000.00 lying around.
