Buildings weren't designed to be retrofitted.
Existing buildings require insulation, windows, air barriers, façade upgrades, consultants, contractors, scaffolding, tenant coordination, and years of construction.
Every project becomes a one-off. The industry treats retrofits as projects.
We think they should be products.
UnBOXED productizes the retrofit itself.
It integrates structure, insulation, air and vapor control, architectural finish, digital panelization, and installation sequencing into one manufactured system.
An inner layer that protects. A down layer that traps heat. An outer shell that faces the world. One panel, dry-fixed over the building you already own.
We turn recycled plastic into high-performance building panels.

Digital twin.
Robotic fabrication.
3D-printed prefabricated retrofit panels over existing wall.
One panel becomes a system. Pre-fabricated off-site, delivered to the building, and dry-fixed in repeating modules: facade, then windows, then a future service cavity (HVAC, ERV, heat-pump pathway), then roof.
UnBOXED panels are installed from the exterior by sliding as vertical legos onto a continuous rail system, enabling rapid tenant-in-place retrofits with minimal disruption.
Real panels. Not renders. Built for real buildings.
Most systems force a trade-off. Ours doesn't.
One System. Any wall. Any climate.
Upgrade existing buildings—without displacement
High-performance envelopes from day one
Built by experts in building science, structural engineering, and advanced manufacturing.
UnBOXED combines expertise in high-performance buildings, structural engineering, advanced manufacturing, and commercialization to transform aging buildings into high-performance assets. Our team has delivered pioneering Passive House projects, scaled industrial manufacturing technologies, and developed innovative solutions for the built environment, creating the foundation for a new generation of tenant-in-place building retrofits.

















UnBOXED delivers a plug-and-play envelope retrofit system for existing buildings. Our standardized panel modules, digital design workflow, and installation process help building owners modernize aging façades while improving energy performance, resilience, and long-term asset value.
Many buildings already require façade repairs, envelope upgrades, or deferred maintenance investments. UnBOXED allows owners to address these capital needs while simultaneously improving building performance, reducing operating costs, enhancing resilience, and protecting long-term asset value.
Unlike many retrofit approaches that require significant interior work, UnBOXED is designed for tenant-in-place installation. This helps owners avoid resident displacement, lost rental income, relocation expenses, vacancy risk, and the operational challenges associated with tenant turnover.
Drawing on building science principles such as the "perfect wall" approach, UnBOXED relocates critical performance layers, including insulation, air, water, and thermal control, to the exterior of the building, where they can be installed with minimal disruption. This exteriorized strategy improves durability, moisture management, comfort, and energy performance while preserving occupied space.
Over time, the exterior retrofit framework also creates opportunities to integrate additional building systems and services as part of future modernization efforts.
Rather than treating decarbonization as a separate project, UnBOXED transforms a required capital investment into a higher-performing, more resilient, lower-risk, and future-ready asset.
Traditional façade repairs address visible deterioration but often leave owners facing the same energy, comfort, maintenance, and resilience challenges.
Achieving meaningful building performance improvements through conventional retrofit approaches can be difficult, costly, and disruptive, frequently requiring extensive interior work, coordination across multiple trades, tenant disruption, and extended construction schedules.
UnBOXED combines façade renewal and building performance upgrades into a single exterior intervention. By addressing enclosure repairs, insulation, weather protection, and resilience together, owners can improve building performance while reducing disruption, labor complexity, and long-term operating costs.
Rather than spending capital simply to restore an aging façade, owners can use the same investment to create a higher-performing, more resilient asset.
Traditional retrofits are often custom, labor-intensive, and disruptive to occupants. UnBOXED uses standardized, prefabricated retrofit modules, reducing project complexity, installation time, and disruption while delivering repeatable performance.
The gains come from fixing the entire envelope at once, from the outside, as a single engineered system. Most of a building's energy loss, comfort problems, and moisture issues trace back to a leaky, thermally bridged enclosure. By wrapping the building in a continuous exterior layer that carries insulation, air, water, and thermal control together (the "perfect wall" principle), UnBOXED addresses the actual source of the loss instead of patching symptoms.
This is where many retrofits fall short. Conventional approaches tend to treat these layers piecemeal, handled by different trades, at different times, and often from the interior. That leaves the gaps, thermal bridges, and air leakage that quietly erode the projected savings, while stacking up coordination, disruption, and cost. Many approaches also lean on adding or upgrading mechanical equipment to hit performance targets, which can look good on paper but introduces new systems that have to be serviced, repaired, and eventually replaced, pushing operating and maintenance costs up over time.
Because UnBOXED puts the performance in the envelope itself rather than in machinery, there is simply less to maintain. The system is passive and durable, and because it is modular, individual panels can be inspected, repaired, or replaced without tearing into the building. Manufacturing the panels off-site to a consistent standard also removes much of the field variability that causes callbacks and premature failure in site-built work.
In short, the industry tends to treat retrofits as custom projects and reach for performance by adding complexity. UnBOXED reaches it by removing complexity, integrating the envelope into one manufactured product that does more of the work with fewer moving parts. That is what brings energy savings and long-term operating costs down together.
Yes. UnBOXED is designed for tenant-in-place retrofits, minimizing disruption to residents and reducing relocation costs and project risk for owners.
Our initial focus is existing multifamily and affordable housing buildings with aging façades, deferred maintenance needs, rising operating costs, or building performance challenges.
UnBOXED is designed as a flexible envelope system that can be adapted to different climate zones, building typologies, and performance requirements.
The underlying wall assembly and installation methodology remain consistent, while insulation levels, attachment strategies, and system configurations can be optimized for local climate conditions and building needs.
This allows UnBOXED to be deployed across cold-climate markets such as the Midwest and Northeast, mixed climates across the Mid-Atlantic, and warmer regions such as California and the Southeast.
The system is applicable to multifamily housing, affordable housing, mixed-use buildings, institutional buildings, and, over time, new construction projects without fundamentally changing the core system architecture.
Because UnBOXED panels are manufactured off-site, installation is faster and more predictable than traditional façade rehabilitation projects. Project timelines vary by building size and condition, but our system is designed to reduce construction duration, minimize disruption, and improve schedule certainty.
Every building is different, but the system is standardized. We configure repeatable panel modules to each building using survey data, digital workflows, and layout rules, creating a scalable process rather than a bespoke solution.
The building owner's GC or approved installation team installs the panels using UnBOXED's installation playbook, onboarding process, and quality-control procedures. This allows us to scale through existing construction capacity rather than building a dedicated installation workforce.
Quality is managed through standardized details, project-specific shop drawings, digital manufacturing workflows, defined QC checkpoints, and installer onboarding.
Before installation begins, UnBOXED provides educational and project-specific training for building owners, architects, and GC teams to ensure a clear understanding of the system, installation requirements, sequencing, and performance objectives. This collaborative process also allows project teams to provide feedback and address site-specific considerations before construction begins.
Combined with quality-controlled manufacturing and documented installation procedures, this approach helps deliver consistent performance across projects, climates, and geographies.
UnBOXED is designed as a modular system. Individual panels can be inspected, repaired, or replaced without requiring extensive reconstruction, helping simplify long-term maintenance and asset management.
No. UnBOXED is designed around owner economics, not subsidy dependence.
Traditional deep-energy retrofit projects often require long payback periods that can exceed 20 years, making adoption difficult for many building owners. UnBOXED is designed to improve project economics by combining required façade renewal and deferred maintenance work with building performance upgrades in a single investment.
Our value proposition is based on reducing lifecycle costs, lowering operating expenses, improving resilience, protecting asset value, and delivering a faster return on investment. Incentives can help accelerate adoption, but our business model does not depend on them.
Building owners are facing increasing pressure from façade safety requirements, building performance standards, resilience mandates, and energy efficiency regulations.
Examples include New York City's Local Law 11 façade inspection requirements, Local Law 97 emissions limits, California's Title 24 Building Energy Efficiency Standards, and emerging building performance standards across North America.
By improving the building envelope, UnBOXED helps owners modernize aging assets, reduce energy use, improve resilience, and position buildings for evolving regulatory requirements.
However, compliance is not the primary reason owners adopt UnBOXED. The primary drivers are façade renewal, asset preservation, reduced operating costs, resilience, and long-term asset value protection.
