Structural Shell Packages
Engineered offsite framing. Turnkey shell erection.
Panelised cold-formed steel systems for custom homes and multi-family developments across California and nationwide.
An integrated structural building system
Custom engineered, manufactured offsite, erected on your jobsite. Built around your architectural plans, site topography and local building codes.
Design, engineering, permitting, panelised manufacturing and shell installation sit with one accountable team. Developers compress schedules. Self-builders get a clear path to dry-in.
shell packages
Built from one of our plans or custom designed to yours.
Small material package
The full material kit needed to get your build weather-tight. We coordinate delivery to site. Your builder or trades handle erection.
- Plan and design included
- Permit-ready drawing package
- Structural steel framing materials
- Exterior metal cladding and roofing
- Windows and doors
- Foundation coordination
- Delivery to site
Shell Build Package
The material kit plus labour to get your build weather-tight. Two scopes depending on build type and purpose.
- Everything in the material package
- Certified erection crews
- Wall, floor and roof framing installed
- Structural sheathing and opening bucks
- Choose weather-tight or complete dry-in
What weather-tight means
Weather-tight, also called dry-in, is the stage where the structural shell is erected and the exterior envelope encloses the building against the elements.
Our system goes past raw framing. Design, engineering, permit approval, offsite panelised manufacturing and jobsite erection are managed as one scope.
Dry-in definitions vary by region and contractor. Your exact inclusions are written into your contract before work starts.
What the CFS building system includes
Wall panels
Load bearing and non load bearing, precision rolled, with pre-punched MEP utility chases.
Roof trusses
Custom steel truss systems and joists engineered for clear spans.
Floor systems
High capacity joist assemblies engineered for acoustic and load requirements.
Hardware and connections
Hold-downs, anchoring systems, lateral bracing and tie-downs.
Exterior sheathing
Factory or field applied structural sheathing to suit the envelope strategy.
The result
A weather-tight shell on your foundation. Straight, non-combustible, ready for MEP rough-in.
One coordinated process
Building should not require managing seven subcontractors before framing starts. Pre-construction and structural erection run as one lifecycle.
Design and structural feasibility
Custom design from scratch or adaptation of your existing plans. Wood-to-CFS conversion. Site evaluation, zoning and engineering scope.
In-house engineering and construction documents
PE stamped structural engineering and calculations. Architectural and framing CD sets. Foundation plans and connection details. MEP coordination and Title 24 or IECC compliance.
Permitting through approval
Permit package preparation and submission. Plan-check comments, revisions and agency approvals. Coordination of third party engineering where required.
Wood-to-CFS conversion, optional
Keep the floorplan and elevations. Convert wood-framed plan sets into pre-engineered CFS panel layouts.
Engineered for site-specific loads
Snow loads, high wind and hurricane tie-downs, WUI wildfire assemblies, seismic ductility, coastal coatings and fasteners.
Offsite precision manufacturing
Steel profiles rolled, cut and assembled into panelised walls and trusses. Straight walls, square corners, no jobsite waste.
Field erection
Jobsite delivery and professional erection. Panel placement and anchoring, floor joists, roof framing, lateral bracing, sheathing and opening bucks.
Exterior sheathing options
Structural OSB or plywood, integrated WRB panels, or glass-mat gypsum for higher fire ratings and commercial assemblies.
Windows and exterior doors
We install your pre-purchased units to manufacturer flashing details, or source and install them as an upgrade. Quoted per project.

Why cold-formed steel
- Up to 50% faster shell erection, lower holding costs
- Pre-punched utility chases speed MEP rough-ins
- Plumb walls cut drywall call-backs
- Non-combustible framing can lower builder risk premiums
- No rot, warp, twist or termite risk
- No nail pops, cracked drywall or stuck doors
- Engineered for fire, weather and thermal movement
