Kosha Build in Layers_edited.jpg

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

  • Adaptive deeper into construction without changing GC means-and-methods

  • No expansion of the project insurance boundary

  • QA release gates + traceability built for DOB/FDNY workflows

Typical construction is structurally outdated in the age of fast-changing data center / mission-critical building envelope performance requirements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

  1. Near-site controlled production (IBZ/industrial parcel)

  2. Accelerated curing to handling strength (targeted cycle-time improvement)

  3. 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.). 

Current State

  • Detailed prototype plan complete

  • Pilot scopes defined (bounded exterior)

  • DOB/FDNY + special inspection pathway being translated into an evidence packet Kosha - Near-Site Manufacturing Systems
