Denver Single-Stair Housing Challenge names three winners

Jury feeback summary: "Detached Living is designed to enhance adaptability, sustainability, and urban integration. The building features a modular unit layout, organized around a central atrium that facilitates natural ventilation. The facade consists of movable louvers and sliding glass doors, allowing residents to regulate shading, airflow, and privacy. Prefabricated concrete and maple wood are employed for durability, thermal efficiency, and sustainability. Movable partitions within units enable spatial flexibility. External staircases separate vertical circulation from living spaces, optimizing safety and usable floor area. Rainwater collection, graywater recycling, and photovoltaic panels contribute to reduced resource consumption. The project aims to balance functional efficiency with environmental considerations while maintaining compliance with local building codes."
