About OLS

Our journey and values

Our Core Principles

Engineering-First

Every recommendation is grounded in analysis, modeling, and verification before anything gets specified.

Sustainability

Reducing consumption and carbon output isn't a selling point. It's the baseline every project is designed around.

Transparency

Itemized estimates, clear tradeoffs, and plain language at every stage. No surprises on scope, cost, or timeline.

Resilience

Buildings that perform under stress: grid outages, extreme weather, rising energy costs. Future-proofing is built into the design, not added at the end.

About Overstory Living Solutions

Overstory was founded on a straightforward premise: the people managing your building project shouldn't also be selling you equipment.

Contractors optimize for what they install. Manufacturers optimize for what they sell. Neither is paid to optimize for your building.

OLS sits on the other side of that table: independent consulting and project management, with no equipment sales, no vendor relationships that compromise the advice.

The name reflects that ethos: harmony with the natural environment, like the uppermost layer of a forest canopy that harnesses energy to support vibrant life in the ecosystems below.

“The forest doesn't optimize one tree. It supports an ecosystem. That's how I think about every project: what does the whole system need? ”
