Duplex Cabin Features Two Tiny Homes in One

This duplex design features two 340-square-foot tiny homes joined seamlessly to resemble a single-family house. Each unit includes a living room, kitchen, bathroom, downstairs bedroom, and loft. With sleek, modern finishes and large windows for natural light, this setup is both practical and stylish. Could it be the perfect fit for your family?
