A cultural focal point on a small Maine island, the Vinalhaven Library was a gift from Andrew Carnegie and is listed on the National Historic Register. The two-room granite structure had served the island population virtually unchanged for over a century, and lacked basic amenities such as running water. The addition contains a children’s room, teen center, reading room, public restrooms, and a staff work room located in a mezzanine. The existing structure was reconfigured and retrofitted with new heating, air conditioning, data connectivity, and wifi. Stained glass depictions of flora and fauna by local artist Janet Redfield were integrated throughout the interior. The addition’s structure is locally felled spruce under the guidance of an island timber framer. Construction systems included pre-stressed panelized roof and walls, and composite siding. The site was landscaped using native plants and granite pavers quarried on Vinalhaven.
