Rare Forms and the Casita Series: Pre-Designed ADUs Built with Sustainability in Mind
Rare Forms, working in collaboration with New Frameworks, offers the Casita series — a line of pre-designed, prefabricated accessory dwelling units developed with a focus on sustainability, health-conscious materials, and practical design. These units are intended to serve a range of purposes, from housing guests and accommodating family members to generating rental income.
The Casita models are positioned as a thoughtful option for property owners looking to add a backyard cottage, in-law suite, or granny flat to their property without compromising on environmental values or indoor air quality.
What Sets the Casita Models Apart
Sustainable Construction: The Casitas are built using locally sourced Massachusetts wood and straw. These materials are selected for their carbon-storing properties, meaning the construction process is designed to have a net positive environmental impact rather than simply minimizing harm.
Health-Focused Materials: Natural, non-toxic materials are used throughout the build. This approach is intended to support healthier indoor air quality for occupants — a consideration that is increasingly relevant in modern residential construction.
Energy Efficiency: Each unit is all-electric and fossil-fuel-free. The Casitas come equipped with advanced heating, cooling, and ventilation systems, and there are options available for off-grid living setups.
Customization: Buyers can personalize their unit with optional finishes, including natural clay and lime plaster or wood finishes, allowing the space to reflect individual preferences while staying within the sustainable design framework.
Delivery and Installation Options
Rare Forms offers flexibility in how the Casita units are delivered and completed. For those within the service area, fully finished models are available. Alternatively, base-level kits without finishes can be ordered for those who prefer to work with a separate ADU contractor or take a DIY approach to the finishing work.
The available Casita models include the Cabinita 300 and the Terra 600, each designed to offer a compact yet functional living space. These detached ADU options are suited to a variety of property types and living situations.
For property owners exploring options for a prefabricated ADU or Casita that prioritizes environmental responsibility and material health, the Rare Forms and New Frameworks collaboration offers a structured, pre-designed path forward. Customization options, pricing details, and installation specifics are available directly through Rare Forms.
