Over the past 50 years, the number of people in the average household has fallen drastically. For the first time in Western world history, the one-person household has become a dominant mode of living. In Manhattan, more than half of all homes have one occupant. For Watertight, we documented 12 New Yorkers and their home interiors with a 3D scanner. We used the Skanect software’s “watertight” function and a 3D printer to create a series of miniature portraits—egg-shaped sculptures the size of a hand. The series of portraits offers a cross-section of a contemporary demographic phenomenon, a form of present-day archaeology.
