At 6:30 a.m. inside the 130,000-square-foot West Coast factory in Carson, California, a fully volumetric steel-framed module for a six-bed student suite glides down the automated line. Interior walls, MEP systems, finishes, and even bathroom pods are already 95% complete and inspected under roof. By the end of the shift another set of modules will be wrapped and staged for flatbed transport to the Cal Poly campus. Tomorrow they will be crane-stacked into one of nine new dormitory buildings. No weather delays. No trade sequencing chaos on a live university site. Just factory precision turning one of the largest student housing projects in California history into finished, move-in-ready space months ahead of traditional schedules.

This is FullStack Modular — the bicoastal volumetric leader redefining mid- and high-rise multi-family, hotel, and student housing in dense urban environments. While many manufacturers focus on single-family or low-rise modular, FullStack builds complete three-dimensional modules (up to 15+ stories) that arrive on site 90–95% finished, enabling entire buildings to rise with unprecedented speed, cost certainty, and quality.

The national urgency is unchanged. America faces a 4-to-7-million-home deficit. The world needs nearly one billion new decent dwellings by 2030. Factory-built volumetric housing still accounts for only 5–6% of U.S. construction value. FullStack Modular proves that volumetric systems can deliver dense, resilient urban buildings at scale — exactly the capability needed where traditional construction is slowest and most expensive.

Founded 2016 — From Brooklyn Roots to Bicoastal Scale

Roger Krulak launched FullStack Modular in 2016 after acquiring and refining the modular production process from a stalled Brooklyn project tied to the Barclays Center. The company quickly established itself as a specialist in fully volumetric, turnkey solutions for multifamily, hotels, and student housing. By late 2024 it opened its West Coast factory in Carson, California (130,000 sq ft), complementing the East Coast facility in Hamden, Connecticut. This bicoastal footprint gives FullStack unmatched reach for urban and institutional projects on both coasts.

The company’s system is fully integrated: proprietary chassis design, flexible module types, and complete building systems that include circulation (elevators, stairs, corridors). Modules recombine to create studios through three-bedroom units, enabling rapid configuration for any project scale.

Manufacturing That Solves Urban Density Challenges

FullStack’s volumetric process builds entire room-sized modules indoors — walls, floors, ceilings, MEP, finishes, and even fixtures — to tolerances impossible in the field. Modules arrive on site ready for stacking, with final connections and minimal finishing. Parallel workflows mean site foundations and infrastructure advance while modules are produced, cutting total project time by 40–60% and delivering 98% schedule predictability.

The Carson and Hamden factories together support high-volume output for mid- and high-rise buildings. Steel framing provides superior fire resistance, seismic performance, and durability — critical advantages in dense urban or institutional settings.

Signature Projects and 2025–2026 Momentum

FullStack’s portfolio demonstrates the system’s power at scale:

  • Cal Poly Student Housing (2025–2026) — the largest modular housing project in the U.S.: 4,200 beds across nine buildings, primarily six-bed suites. Production began in the new Carson factory in 2025; first occupancy targeted for Fall 2026. This precedent-setting CSU project is helping address California’s student housing crisis through modular innovation.
  • Previous high-profile wins include 15-story multifamily towers, affordable housing (NYC HPD RFP winner), hotels, and mixed-use developments up to 322 feet tall with ground-floor retail and LEED Silver certification.

The company’s turnkey model — design, manufacture, transport, and installation coordination — gives developers and institutions single-source accountability and predictable outcomes.

Workforce and Operational Excellence

FullStack employs skilled teams in both factories, combining advanced manufacturing expertise with architectural precision. The controlled indoor environment provides safer, year-round conditions and attracts talent in a national construction labor shortage. The bicoastal expansion has created hundreds of stable manufacturing jobs while supporting faster delivery for urgent institutional needs.

Sustainability Built Into the System

Volumetric modular construction dramatically reduces material waste, site disturbance, and construction-phase emissions. Factory precision enables tighter envelopes, efficient MEP systems, and higher-performance buildings. Many FullStack projects target LEED or equivalent certifications, and the Cal Poly project advances the CSU system’s sustainability goals through off-site fabrication.

The External Ceiling

FullStack’s factories and volumetric system are not the constraint. Zoning and permitting processes slow to recognize high-rise modular, varying local code interpretations, transportation restrictions on module size, and institutional procurement timelines remain the real barriers. Even the most advanced volumetric leader cannot bypass every regulatory or campus approval process.

Why FullStack Modular Ranks Twenty-Second in This Series

Following the volume giants, multi-family volumetric pioneers, custom residential benchmarks, and specialized innovators, FullStack earns twenty-second place as the urban high-rise and institutional volumetric specialist. Its bicoastal factories (Hamden CT and Carson CA), fully volumetric system capable of 15+ story buildings, turnkey delivery for multifamily/hotels/student housing, and landmark 2025–2026 Cal Poly project (4,200 beds, largest modular student housing in the U.S.) make it the go-to for dense, resilient urban and institutional solutions. In a series spanning national scale to niche mastery, FullStack represents the high-density volumetric capability essential for solving housing shortages in America’s cities and campuses.

That ranking rests on verifiable bicoastal infrastructure, major institutional wins, and its focused leadership in the hardest segment of the modular revolution.

The Larger Question

Can a bicoastal volumetric specialist like FullStack Modular convert its factory precision, 40–60% timeline advantage, and landmark projects such as the 4,200-bed Cal Poly development into broader zoning, code, and procurement reforms that unlock high-rise modular at national scale?

FullStack has built the factories, refined the system, and delivered the proof — modules are stacking into entire buildings on schedule and on budget. The larger question this series will keep asking is whether America’s urban regulatory and institutional systems will finally allow volumetric modular to deliver density and speed at the volume the housing emergency demands.

The universities, cities, and developers facing acute housing shortages cannot wait for the next planning commission cycle.
