DONE.
Done. You get the Cave. A finished, climate-controlled space with HVAC, finished walls, a private half bath and mezzanine already included. No architect to hire. No contractor to manage. No permits to chase just to make it usable. And it’s all on 135th Street in the historic Martin City entertainment district.
THEM.
Do It Yourself
The Other Guys. Typically located in an industrial park or way out in the country. You get the shell. A metal box, with a roll-up door, sometimes a communal clubhouse and gated perimeter. Want a bath, HVAC, kitchenette or mezzanine? Those upgrades require hiring an architect, contractor and obtaining permits...all at additional cost.
What that means
DONE. vs. D.I.Y.
They give you the starting point. We give you the finished Cave. You spend your time making it yours, not managing a construction project.
Each row is their listed price as published on their website, then the estimated extra to reach HVAC, finished walls, a private half bath, and a mezzanine. That all-in sits under Metal Box. Our published finished price sits under FlexCaves. The finish number is an estimate, not a contractor bid.

Estimate only. Their contractor prices the build-out. Ours is already in the sticker.
FlexCaves lease is $23 / SF NNN on floor + mezz for a finished cave, 3-year minimum, 2027. Their listed rents are for an unfinished metal box, available now. Finish is still extra — same $40,000–$80,000 estimate — on top of rent. Those listings do not say NNN.
