Project Overview:
Engaged by Pleasant Hill to create its first civic building in many years, we were asked to design a 21st century library, with flexibility for all ages to feel welcome and encouraged to learn, create, and explore. From its free-span central hall to pavilions housing a ‘messy makerspace’, ‘story lab’, and ‘retreat’ for quiet reading, Pleasant Hill Library provides immersive spaces and uses for the entire community. A south-facing clerestory and large circular skylights bring natural light indoors, while the all-electric, highly energy-efficient design includes radiant heating and cooling, natural ventilation with night-flush operability, and a rooftop PV solar array.
