Marketing awkward, narrow, or neglected infill plots is a notorious challenge for land agents; buyers simply cannot visualize the potential. This project transforms a cluttered, uninviting 70SQM side-alley into a masterclass in "Warm Minimalism." By utilizing a rapid workflow of 3D massing wireframes, generative AI rendering, and precise Photoshop composition, we illustrated how an overlooked plot can become an ultra-premium, light-filled luxury home featuring discrete entrances and seamless indoor-outdoor courtyards.
