A newly completed residence in Victor, Idaho, United States, is showcasing how alternative materials and Passive House design strategies can support low-carbon residential construction in the Mountain West. Designed by Love Schack Architecture, the project—known as Aska’s Animal Haus—uses prefabricated straw insulation panels to reduce environmental impact while delivering high performance and energy efficiency.
Completed in 2025, the 3,292-square-foot home was designed to serve both as a family residence and a base for a nonprofit animal rescue operation.
A Home Designed for Family and Animal Rescue
The homeowners operate Aska’s Animals, a nonprofit animal rescue that cares for animals such as dogs, pigs and goats. To accommodate both family life and the rescue operation, architect Lindsay Schack designed the house around the site’s natural slope.
The layout separates living and operational spaces:
- Upper level: primary family living spaces
- Walkout basement: durable, sanitary facilities for rescued animals with yard access
When the rescue operation eventually relocates to a dedicated facility, the lower level can be converted into additional family living space, ensuring long-term adaptability.
Schack describes the homeowners as “legacy clients,” meaning they intend to live in the home long term rather than build for resale, which shaped the focus on durability and sustainability.
Straw Panels Replace Conventional Foam Insulation
A defining feature of the straw insulated Idaho home is the use of prefabricated straw insulation panels manufactured by New Frameworks, a Vermont-based company expanding its presence in the region.
These panels function similarly to structural insulated panels (SIPs) used in conventional construction but replace foam insulation with compressed chopped straw, an agricultural by-product.
Key benefits include:
- Low-carbon insulation material derived from agricultural waste
- Fire resistance comparable to heavy timber construction
- Pest resistance due to dense compression
- Compatibility with standard drywall or natural plaster finishes
Electrical and plumbing services run through an interior service chase wall, making the installation familiar to local tradespeople.
Passive House Principles and Healthy Materials
The design reflects Love Schack Architecture’s long-standing commitment to Passive House performance standards, prioritizing energy efficiency and indoor environmental quality.
Schack explained that while many energy-efficient systems exist, they often rely on materials that are difficult to recycle or potentially harmful to indoor air quality.
“We recognized early on that while there’s good technology out there that can relate to energy efficiency, not all the materials involved are non-toxic or easy to recycle,” Schack said. “We decided we would like to design with materials that we felt strongly about.”
Traditional straw bale construction was not feasible for the project because Idaho’s seismic requirements require extensive structural framing, which can increase labor costs. The panelized straw system offered a practical alternative.
Construction Challenges and Lessons Learned
Despite its innovative materials, the project largely followed conventional construction processes.
Local builders quickly recognized the panel framing system, and owner-builder Will Langman was able to erect much of the structure himself using a Gradall lifting machine instead of a crane, helping reduce construction costs.
However, the project faced a challenge when heavy rain arrived shortly after the straw panels were delivered to the site. The team installed moisture sensors to monitor the panels as they dried.
According to Schack, the experience reinforced an important construction lesson: schedule installation during the driest possible weather conditions.
A Model for Low-Carbon Housing in the Mountain West
Located just across the border from Teton County, Wyoming, where land and construction costs rival those of nearby Jackson, Wyoming, the home represents a different approach to building in the region—one focused on sustainability, long-term durability and ecological responsibility.
By combining prefabricated straw insulation, Passive House principles and adaptable spatial design, Aska’s Animal Haus demonstrates how low-carbon construction techniques can be integrated into modern residential architecture across the Mountain West.
