While this one-bedroom Park Slope co-op at 443 Seventh Avenue might not exactly be sprawling at 700 square feet, for $780,000 the diminutive garden duplex packs a lot of living space into its two-and-a-half levels. The large and sunny patio garden is the obvious draw for summer parties and spring planting. A wood-burning fireplace ups the cozy factor in cooler months. And a loft level sandwiched between upstairs and down might be just the place to store your seasonal gear off-season. Two blocks away, Prospect Park is another warm-weather plus, and living steps from welcoming spots like Talde and Cafe Grumpy makes it easy to stay warm in winter.
