Build faster in NYC without early envelope lock-in.
Flexibuild™ is a deployable near-site micro-factory system that produces lightweight and high-performance exterior building envelope panels enabling mission-critical projects to maintain adaptability late into construction
Typical construction is structurally outdated in the age of fast-changing data center / mission-critical building envelope performance requirements
Kosha is an NYC-based construction systems company building Flexibuild™, a deployable near-site micro-factory that manufactures lightweight exterior envelope panels for mission-critical urban projects.
Our primary target is colocation/interconnection data center expansions. Conventional precast/modular supply chains force envelope decisions 18-30 months before commissioning, converting late changes into redesign, rework, and schedule slips.
Flexibuild combines:
​
(1) Robotic additive concrete fabrication
(2) Accelerated Concrete Curing (ACC)
(3) QA release gates
​
Without changing GC means-and-methods or expanding the project insurance boundary. We deliver certifiable panels with ~50% lower dead load than mainstream alternatives from Industrial Business Zone sites during construction​
Lightweight panels unlock retrofit-adjacent NYC pilots
-
Target ~50% lower dead load vs mainstream alternatives (to be validated)
-
Avoids added structural reinforcement where load reserve is limited
-
Reduces lift constraints + disruption, making bounded pilots easier to approve
What Flexibuild Is
-
Near-site controlled production (IBZ/industrial parcel)
-
Accelerated curing to handling strength (targeted cycle-time improvement)
-
QA release gates + traceability + inspection packet

We are a platform company, not a contractor
Flexibuild changes who fabricates exteriors and where and when envelope manufacturing happens, creating a controllable buffer between early assumptions and construction reality.
​​
What Flexibuild doesn’t change is GC sequencing, site safety perimeter responsibility, and project insurance boundary.
We are seeking pilot partners to turn a detailed prototype plan into a revolutionary engine for today’s mission-critical infrastructure.
We are pre-deployment. We are seeking pilot partners to translate DOB/FDNY- and special-inspection requirements into an approval-ready evidence packet.
Our ideal customers are NYC-area owners/developers and GCs delivering colocation/interconnection data center expansions and retrofit-adjacent upgrades where requirements stay late-binding (e.g., due to interconnection timing, shifting cooling architecture requirements, equipment lead times, approvals, etc.).
