King Street is a private real estate investment management firm focused on serving the complex needs of science-based companies and institutions. Our experienced professionals combine big-company experience with a hands-on entrepreneurial approach to execute its tightly defined mission.

Who We Are

We created our company to provide space solutions to companies whose missions inspire us: pharmaceutical and bio-tech firms racing to develop life saving drugs, makers of medical devices and diagnostic tools, and clean tech companies harnessing renewable materials and energy sources.

Satisfying the sophisticated technical requirements of these innovators is just where we start. Today’s lab space must help attract and retain top scientific personnel and create an atmosphere which accelerates collaboration and discovery. We call this approach “placemaking”.
