RPA LivingHome 1
Architect:
Richard Pedranti
Timeless modern design meets advanced building science in this comfortable, four-bedroom home. Following Passive House standards, the RPA LivingHome 1 was designed to provide maximum energy performance, excellent indoor air quality, and unparalleled thermal comfort.
An open-plan kitchen, dining, and living room forms the heart of the home, with large windows and an oversized sliding-glass door to the back deck. A gracious front porch provides a warm welcome, while an attached two-car garage (optional) and side entry hall cater to the practicalities of daily life.
The home’s classic pitched roof (optimized for photovoltaic panels) creates a cozy loft with two bedrooms, a full bath, and a bonus room for a children’s play space or home office. A first-floor laundry room and two first-floor bedrooms, each with their own bathroom, provide one-story living that’s perfect for aging in place—or young families who appreciate a quiet space for mom and dad.
The RPA LivingHome 1 was designed to meet Passive House* energy standards, shipping complete with best-in-class smart home technology, energy monitoring, and high-performance fresh air systems for heating, cooling, and ventilation.
*Passive House certification is administered through Passive House Institute US (PHIUS) or Passive House International (PHI). Certification is entirely optional, so certification fees are not included in the LivingHome cost estimate.

Sustainable Operations
Our Tejon Ranch factory operates with a small footprint, utilizing 100% solar power and resource-efficient smart lighting and HVAC, with low-flow plumbing fixtures and a water reclamation system for irrigation. In production, our advanced digital modeling drives our precision manufacturing equipment, maximizing material utilization for minimal waste. And we utilize building materials with recycled content whenever possible.
High-Performance Buildings
Utilizing state-of-the-art manufacturing equipment to produce building components in a controlled factory setting yields much tighter tolerances than manual, site-built construction. Together with precision-fill insulation, taped seams, and other high-quality building materials and practices, Plant Prefab's factory manufacturing gives LivingHomes a tight building envelope that exceeds California's strict Title 24 energy performance requirements. This means better occupant comfort and better energy efficiency for the life of the home.

Our strict materials standards, advanced engineering and building processes, and rigorous factory quality control delivers extremely well-built, durable homes.
Our Plant Virtual Build process, in which we build a 100% complete digital twin prior to construction start, ensures design, structural, and manufacturing excellence from the first day of framing to the final finishes.
Panelized components are constructed by state-of-the-art manufacturing equipment, then shipped to site or assembled into volumetric modules and finished by highly-trained and experienced tradespeople.
Materials are extensively researched and carefully vetted for durability and sustainability.
In addition to our in-house quality assurance, all components are inspected by a third-party, state-certified Quality Assurance Agency under the California Department of Housing and Community Development's Factory-Built Housing program.
Our standard homes are designed for the way you live, and they’re customizable to your tastes. LivingHomes incorporate functional details and a wide array of carefully-selected finishes, fixtures, appliances, and smart home technology for you to choose from.
Every LivingHome offers the ability to incorporate the latest smart home technology, including best-in-class connectivity, virtual assistance, home security, climate control, and energy monitoring. You can personalize your smart home experience with your choice of upgrades, like Alexa voice-controlled entertainment streaming and appliances.
We’ll even teach you how to utilize all the benefits of your new smart home through a visit from an Amazon expert, who will activate all devices and help you set up personalized routines.
