Repositioning existing buildings has become one of the most strategic ways to bring specialized facilities to market. In Hopkinton, Integrated Builders put that strategy into action by transforming traditional office space into a 65,000sf high-bay life sciences facility for Isto Biologics.
Designed by The Colwell Group, the project centered on the careful conversion of an existing office building into a technically capable environment for a growing biotechnology user. Rather than starting with a ground-up structure, the team worked within the constraints and opportunities of the existing building, evaluating how the space could be modified to meet new operational requirements while preserving the value of the original asset.
A defining component of the repositioning strategy was the selective removal of a portion of the existing second floor. This work created a 24-foot clear height in targeted areas of the building, allowing the space to better accommodate specialized warehousing needs, cleanroom-related functions, and technical operations. That structural intervention was central to the project’s success, giving Isto Biologics the vertical clearance and flexibility needed for more advanced life sciences use.
Converting office space for life sciences is never simply a cosmetic renovation. The process requires close coordination among structural modifications, building systems, specialty environments, logistics planning, and long-term tenant operations. Integrated Builders’ construction approach focused on aligning those elements so the finished facility could support both immediate occupancy needs and future growth.
The repositioned building now provides a more efficient, purpose-built setting for Isto Biologics, supporting the tenant’s need for specialized storage, cleanroom-related functionality, and operational flow, while also improving the overall usefulness of the existing property. For owners and tenants, that balance is often the real value of adaptive reuse: taking a building with strong potential and reshaping it into a higher-performing asset.
The Hopkinton project also reflects a broader trend across the region’s commercial real estate market. As life sciences companies continue to seek flexible space beyond the most constrained urban lab clusters, existing office buildings can offer a valuable foundation for repositioning. With the right construction strategy, these properties can be upgraded to meet advanced technical requirements while reducing the need for entirely new development.
For Integrated Builders, the Isto Biologics project demonstrates the company’s experience delivering complex renovation and fit-up work in the science and technology sector. The completed facility shows how thoughtful repositioning can extend the life of an existing asset, support a growing biotechnology tenant, and create a space more closely aligned with today’s technical and operational demands.
In a market where speed, flexibility, and building performance matter, the repositioning of the Hopkinton office building offers a clear example of how strategic construction can turn underutilized space into a highly functional life sciences facility.
