The Health Sciences Library (HSL) space planning project aims at modernizing the existing library interior space considering three scenarios for scope and cost. The project consists of the development of a long-term vision and architectural plans for an updated library building based on design research and multi-stage participatory activities. It expects to comprehensively incorporate the opinions of students across all health sciences colleges to determine programmatic needs and priorities while consulting faculty and administrators to identify unmet needs relevant to library space. This evidence-based and user-centered approach will support HSL’s vision, assist in fundraising, and broaden stakeholder participation. Schematic design packages based on different scenarios will assist internal and external collaborators in cost estimation and further design development.
