REGATHER is a web-app that aims to facilitate the process of community asset mapping for found, reclaimed, salvaged, and/or forage-able material sites in the U-District neighborhood. It offers tools for the collaborative mapping of physical found material sites and a library of DIY project guides to share knowledge for using them. Our current feature project is a customizable gathering structure made entirely from found materials and without hardware. The basic structure is connected through dowel rod joints, and includes a tarp roof, coffee bag walls, and modular shelves clamped onto cross beams through bike tube rubber bands.
