JLF Architects, based in Bozeman, Montana, and Jackson Hole, Wyoming, believe first and foremost that architecture should be rooted in its particular place, responding in a meaningful way to the natural or built environment. Using local materials and partnering with the best local craftsmen, JLF Architects seeks to create buildings that are tactile and modern, environmentally responsible and authentic, artful and crafted.    Now more than 30 years since its founding, the firm has grown along with the range and complexity of its projects, and still considers the desire to build in part-nership with the land to be an approach that remains valid and increasingly resonant.
