McCall Townhomes
About the McCall Townhomes
The McCall Townhomes were developed to provide workforce housing for St. Luke’s employees in a resort market with limited housing availability. The site faced a short construction season, limited local labor, and heavy snow-load requirements. Funding cycles further constrained timing, requiring rapid mobilization once capital was approved.
Approach
Irontown adapted its Berkeley multifamily layout to meet local code and site conditions, including snow-load roof design, upgraded insulation, and a commercial-grade TPO roof system. Modules were fabricated off-site while site work and crane planning progressed in parallel. Tight staging and sequencing allowed modules to be placed efficiently without excessive on-site handling or site disruption.
Key Outcomes:
- Short build season accommodated without extending on-site duration.
- Cold-climate envelope addressed heavy snow-load and insulation requirements.
- Tight-site logistics enabled efficient crane staging with minimal tree disturbance.
- Modular delivery reduced labor dependency in a remote market.
- Prototype layout supports phased future development.
Main Problem solved
Problem
A remote workforce housing project risked schedule slippage due to weather, labor availability, and a compressed construction window.
Constraints
- Short seasonal build window
- Heavy snow-load and cold-climate requirements
- Tight site with limited staging area
- Limited local labor availability
What Modular Changed
- Enabled rapid fabrication independent of site conditions
- Reduced weather exposure during critical construction phases
- Simplified on-site sequencing through pre-planned crane logistics
- Supported predictable delivery aligned with funding cycles
How We Delivered It
Irontown supported early feasibility discussions and adapted a proven multifamily design for local requirements. Factory manufacturing proceeded while site preparation and crane logistics were finalized. Modules were delivered and set using a coordinated staging plan designed for tight access. Final roofing, stitching, and closeout were completed on-site with minimal schedule extension.
Proof Notes
- Snow-load roof and insulation strategy designed for mountain climate
- Crane staging reduced unnecessary module handling
- Strong coordination with GC and local trades
