Capabilities
TESH Group coordinates the capabilities required to plan, approve, produce, deploy, repair, and deliver housing projects across California. The platform connects feasibility, design, engineering, permitting, residential products, structural steel, light gauge steel, modular and panelized systems, ADU deployment, retrofit, compliance, field execution, and builder/GC support through five operating companies.
Modular & Volumetric
TESH delivers both fully volumetric modular and panelized hybrid steel systems, engineered, fabricated in owned facilities, delivered, and set in place. Below are projects we have built across both paths.
Fully finished three-dimensional modules built on a factory line, delivered up to roughly 90 percent complete and set in place in days. Built for repeatable unit types at scale: multifamily, affordable, and workforce housing.
84-unit affordable housing · with ABS
An 84-unit affordable housing development delivered as factory-finished light gauge steel volumetric modules, craned and set in place on site.
Flat-packed wall, floor, and roof panels in light gauge steel, reinforced with structural steel where the building needs it. Fabricated off-site and assembled on-site for speed and design flexibility across hospitality, senior, and infill projects.
1019 Colorado Blvd · 80,000 SF
An 80,000-square-foot hospitality development framed with panelized light gauge steel and structural steel lateral reinforcement, fabricated off-site and assembled on-site for speed.
17349 Roscoe Blvd · 53,000 SF · with ABS
A 53,000-square-foot senior housing facility framed with a panelized hybrid steel system, produced in collaboration with ABS.

Case Studies
Two Los Angeles multifamily projects where switching to load-bearing light gauge steel changed the math, on schedule, on crew size, and on density. Both in collaboration with ABS.
Multifamily · two phases
8711 S. Harvard Drive, Los Angeles
A two-phase multifamily development, each phase a 273,000 SF building of four levels over a concrete podium. The first phase was framed in wood as designed: a crew of 85 framers and 156 working days to top out.
The second phase, a mirror image of the first, was redesigned by our team in light gauge steel panels. With roughly 60 percent of the framing prefabricated in a controlled factory environment, the field crew dropped to 25 and topped out in 85 working days. We also provided field training for the original wood framers, who finished their phase on schedule.
Multifamily infill
Downtown Los Angeles, CA
Astani Enterprise Development brought us a schematic design for 8th & Grand, originally drawn in wood at five levels over a concrete podium: 500 units across 500,000 SF. They asked us to apply our load-bearing light gauge steel system to add density.
Approved by Tony Ghodsi, SE of Englekirk Engineering, the project was redesigned to six storeys over podium at 600,000 SF. Eliminating double party walls and redundant staircases raised the unit count to 700. It sold to Carmel Partners and was built as an infill with structural steel and light gauge steel framing.
C01
Early project evaluation, site review, use analysis, scope planning, and delivery strategy. The first layer of clarity before design, permitting, production, or field execution begins.
C02
NAXA Design provides the front-end planning and approval infrastructure: architectural design, structural engineering, MEP (mechanical, electrical, plumbing) engineering management, entitlement, permitting, documentation, and approval-path coordination, carrying projects from design concept through permit approval.
C03
LyteMods provides the residential product layer: pre-designed homes, pre-designed ADUs, custom homes and ADUs, and selected volumetric residential products.
C04
Cal Steel Modular provides structural steel, light gauge steel framing, steel assemblies, reinforcement, fabrication, and field steel execution for homes, rebuilds, ADUs, and builder-supported projects.
C05
Cal Steel Modular supports modular components, panelized wall systems, volumetric assemblies, wet-room pods, and repeatable framing packages, all produced through its owned off-site fabrication facility. A steel-based pathway for scalable residential delivery.
C06
ADU Concepts supports single-family and multifamily ADU deployment: backyard ADUs, garage conversions, apartment-property ADU programs, and density-adding housing, plus the LyteMods dealer and certified-installer model.
C07
Cal Retrofit provides retrofit, balcony compliance, structural remediation, multifamily repair, seismic work, and compliance-driven construction, backed by close to a decade of multifamily-sector experience.
C08
Field execution, installation planning, delivery sequencing, logistics, staging, quality control, and closeout: the field-delivery layer that connects approved plans, fabricated systems, ADU deployment, and retrofit work.
C09
Through Cal Steel Modular, TESH Group serves as a steel, LGS, modular, and panelization partner for projects led by outside general contractors: custom homes, fire rebuilds, infill projects, and larger housing programs.
