Named the Rookery—a term for a colony of birds—the addition provides uniquely stunning views over the 100-acre Angelica Park and features a new multipurpose room suitable for use as a classroom and community gathering and event space linked to a covered outdoor rooftop classroom by an operable glass wall. Below, a new breezeway, complete with wood-burning fireplace, overlooks the wetlands and provides additional flexible program space. Ultimately, the building serves as a demonstration center for environmental education in support of the organization's mission.

Interior and exterior spaces immerse visitors in nature through views of the outdoors from 99% of occupied areas, daylighting, natural ventilation, and direct outdoor access. Bird-friendly acid etched glazing, dark sky compliant lighting, native plantings, and onsite stormwater management all help to support the local and regional ecosystem. Interpretive panels and signage throughout the facility along with sustainability tours highlight building and site features, including rain barrels, rain chains, sheep’s wool insulation, reclaimed and recycled materials, and daylight sensors, that visitors can use in their own homes.

Most importantly, the new facility has allowed Berks Nature to expand and diversify its educational programming, increase the number of children with direct access to nature, and enhance its service to the community.
