Combining creative nous with careful planning, architect Mark Lawton creates a net-zero home inspired by the typology of a fisherman’s shack.
"The arrival sequence became the genesis for the design," says architect Mark Lawton of the net-zero home he brought to life on the banks of the Westport River. "To get there, one must travel down a short, heavily wooded dirt road. After a sharp bend, a framed vista of the river explodes before you."
This hidden cove was formerly home to a fisherman’s shack and an oyster bed—and although it looks idyllic, the site posed a considerable set of constraints, including a modest and unmodifiable footprint and a closely situated neighboring property. "All of my client’s program had to fit into a simple rectangle without a high roofline, which would block the neighbor’s water view," Lawton notes. The property is also located in a high-impact flood zone, with the potential for surging waters to wash up the banks.
