Hella more than that, yo. My deck is 8x12 and it's claustrophobic. One damn hammock and there's barely room for conversation, let alone conversation herbs and spices. Now obviously - thee's "need" and need. I lived an entire summer in the 6x8 space above the bathroom of a Quanset hut. Shower at the docks. Eat at the grocery store. But holy fuck when you escape that it's like a cork out of a champagne bottle. I bought a desk that was 4x6 and then another 3x5 just for good measure. We own the Not So Big trilogy. I'm a firm believer in scale. I recognize that most cultures on earth shun the wastefulness with which Americans put roofs over emptiness. But hot damn - buddy of mine shared a 6,000 ft loft with three other guys for a few years and I gotta tell ya, hopping on the skateboard to cut down on the transit time to the bathroom is its own specail form of intoxication. How much space do I need? MOAR.
