Wouldn’t it be nice to take a stroll in the park right now, roll around in the grass, reach out and touch the beautiful foliage?

Oh, right, everything is frozen...except this two-story living green wall inside a $25K per month 4-bed, 4-bath Cobble Hill townhouse. Cash in your 401k, crank up the heat, dig out your flip-flops and summer all year long in this 5,200-square-foot former commercial space, where floor-to-ceiling windows, a huge skylight and a one-car garage complete your seasonal cocoon.
