Second Life: Line and Mat / New York
Adaptive Reuse
2019 - Ongoing

To date, the Second Life initiative has developed two mini-building types, the Line and the Mat, each of which is suited to an existing building type and size. The interim program for each of the mini-buildings is identified based on the needs of the community and is designed to transition into long-term occupancy after an initial 3- to 5-year revitalization period. The mini-buildings are lightweight and readily disassembled if no longer needed.

Line Mini-building
The Line is a freestanding mini-building that was developed for the Second Life initiative. It creates work and learning rooms within vast, vacant, or empty spaces—such as formerly industrial buildings or empty retail storefronts—without requiring extensive renovations while meeting Healthy Building standards.

Unlike typical interim solutions—such as storage containers, which compartmentalize space without adaptability—the Line can either connect to or separate from surrounding areas of the vacant building. It is a modular structure that supports transparent panels, which can be fully open or closed. Raised off the floor, the platform is passively cooled in warm months and independently climatized with radiant heating and thermal curtains in cold months. Surrounding mesh supports the growth of climbing plants, which create personal green spaces: providing connection to nature for our well-being.

The Mat is an approach to vacant homes and developed as part of the Second Life initiative. It allows users to convert formerly residential—and thus smaller—buildings with inadequate structural integrity into dynamic spaces for local businesses or community use. This approach defines building elements that are permanent and those that are designed for interim use.
The open floor framing system consists of modular wood components that streamline the construction process, minimize costs, and reduce the need for skilled labor. This open framework stabilizes the existing structure while supporting rooms for small groups, if necessary, even to separate themselves. The rooms are enclosed in visually permeable panels that are operable and are semi-climatized with radiant heating and thermal curtains. Once permanent occupancy has been established, these rooms can be uninstalled while leaving the floor framing structure intact.
