Scale smarter with expert facility expansions and retrofits.


Building a cultivation facility isn’t just about drawings and permits. It’s about keeping chaos in check from day one. We manage construction, expansions, and retrofits for cannabis facilities that need to run right the first time. From the first stake in the ground to the final commissioning test, we make sure every trade, vendor, and system stays aligned. Cultivation projects can get messy fast. Our job is to bring order to the moving parts, coordinate vendors, catch issues early, and keep timelines and budgets intact. With years of cannabis and CEA experience, we make sure your facility gets built exactly the way it was designed to perform.

From new builds to complex retrofits, OSH acts as the central point of communication across every stakeholder. We coordinate contractors, vendors, and engineers to keep projects aligned, on time, and within budget.
Upgrading or expanding an active cultivation facility is one of the toughest challenges in the industry. Your director of cultivation already has a full-time job running the operation: managing a complex construction or retrofit on top of that stretches resources thin and increases risk. OSH steps in to manage the process strategically, minimizing downtime, maintaining environmental stability, and preventing disruptions to production.
We stay on-site through commissioning so every system functions exactly as designed. Our detailed handover process includes staff walkthroughs, vendor documentation, and post-launch monitoring to keep your team fully equipped for a seamless transition into daily operations.
Scaling a cultivation facility takes more than new equipment; it takes integration, oversight, and follow-through. OSH partners with licensed operators to plan and execute expansions and retrofits that work the way they’re supposed to.
