Scalable Owner-Occupied Solar Housing
An owner-occupied, solar-powered housing model that centers dignity, stability, and community.
The Four-Door Model: Multi-Unit, Owner-Occupied Housing
Greenhaven Solutions treats housing as an interconnected system rather than a single dwelling. Our Greenhaven 4-Door Affordable Housing Model divides a property into four living units—one owner-occupied and three rental—sharing an efficient solar energy framework. This arrangement provides energy resilience and predictable utility costs while preserving long-term affordability and social stability. The approach centers on dignity and belonging within sustainable neighborhoods, and it is designed to be repeatable across communities. We seek a development partner, such as Lennar Homes, to translate this model from pilot properties to broader scales, aligning disciplined development practices with a national footprint.

Property-as-a-System: Four Units on One Parcel
A single site is divided into four dwellings—one owner-occupied and three rentals—linked by a shared solar energy system. This configuration reduces duplicated infrastructure, improves energy accounting, and supports privacy, access, and maintenance planning.

Repeatable Development Toolkit
The model uses a consistent design and permitting approach, enabling four-unit parcels to be replicated across communities. The framework includes site selection criteria, unit layout options, and a shared energy system that scales with project size while maintaining the core owner/renter mix.
Greenhaven Model Offerings
We view housing as a platform for dignity, stability, and long-term affordability. Our approach centers on a four-unit configuration within a single property: one owner-occupied unit and three rental units, all served by a shared solar energy system. These offerings are designed to be scalable and repeatable across communities, supporting seniors, mission-driven buyers, and diverse households while delivering energy resilience and lower utility costs. We are pursuing partnerships, including Lennar Homes, to extend this model to additional neighborhoods.
Greenhaven 4-Door Affordable Housing Model
Converts a single property into four living units: one owner-occupied and three rental units, interconnected by a shared solar energy system. The layout prioritizes dignity and long-term affordability, with energy resilience and lower utility costs as core benefits. The model is designed to be repeatable across sites while maintaining quality and community focus.
Shared Solar Energy System Across Four Units
A single solar installation serves all four units, delivering energy resilience and predictable utility costs. The system is designed for reliable operation and straightforward maintenance, ensuring equitable energy access for the owner and renters within a unified energy platform.
Scalable, Repeatable Development Framework
A disciplined process to replicate the Greenhaven model across properties and communities. The framework covers site selection, design standardization, permitting, cost control, and project management to ensure consistent outcomes while preserving the model’s emphasis on dignity, stability, and sustainable living.
Core Features
Greenhaven Solutions uses the Greenhaven 4-Door Model to turn a single property into four living units—one owner-occupied and three rentals—sharing an efficient solar energy system. The approach centers on dignity, stability, and long-term affordability, while delivering energy resilience and a sense of community. The design is repeatable and scalable for broader adoption.
One owner-occupied unit plus three rentals
A single property is divided into four units: one owner-occupied and three rental units. The four units share an efficient solar energy system, which lowers energy costs and makes utility expenses more predictable for residents.
Shared solar energy system
All four units are powered by a centralized solar setup. This configuration reduces utility bills, improves energy resilience, and supports long-term affordability for residents.
Scalable and repeatable design
The model is designed to be replicated across properties and communities. It follows a clear process from planning and construction to occupancy, and is positioned to scale through partnerships with builders such as Lennar Homes.
Core Benefits of the Greenhaven 4-Door Model
Our approach treats housing as a shared responsibility and a platform for dignity. The Greenhaven 4-Door model turns a single property into four living units — one owner-occupied and three rental — linked by a shared solar energy system. This design supports energy resilience, long-term affordability, and community stability, while remaining repeatable enough to scale across multiple communities. It aligns with values of stewardship, belonging, and practical resilience for seniors and mission-driven buyers alike.
Energy resilience and lower utility costs
A single solar system serves all four units, creating a reliable energy source and reducing exposure to utility price swings. This shared infrastructure helps keep energy costs more predictable for both the owner and tenants, supporting sustained affordability over time.
Dignity and stability through ownership and tenancy
The model pairs owner-occupancy with rental units, fostering financial stability and a sense of belonging. This structure supports seniors and diverse households by providing secure, stable housing within a connected, care-forward community.
Scalability and repeatability
Designed to be replicated on additional properties, the model uses consistent processes and standards. This enables reliable quality, cost control, and faster deployment, expanding access to affordable, solar-powered homes across communities.
Alignment with seniors, mission-driven buyers, and scale through partnerships
By addressing housing shortages and prioritizing sustainable, affordable living, the model resonates with seniors and mission-driven buyers. We are pursuing a strategic partnership with Lennar Homes to extend this approach across multiple communities, maintaining disciplined development practices while increasing reach and impact.
The Process: A Repeatable Path to Dignified, Solar-Powered Living
Greenhaven’s process turns a single property into four connected homes—one owner-occupied and three rentals—through a shared solar energy system. Each step enshrines dignity, stability, and long-term affordability, while building energy resilience and a sense of community. The approach is designed to be repeatable and scalable, so that sustainable housing can become a common standard rather than an exception.
Clarify the Model and Principles
Define the Greenhaven 4-Door Model: one owner-occupied unit and three rental units within a single property, all linked by a shared solar energy system. The model centers dignity, stability, and long-term affordability, with priority given to energy resilience and the formation of a supportive community.
Design, Site, and Systems Planning
Translate the concept into tangible plans: layouts that support accessibility and privacy, shared infrastructure for solar generation and storage, and energy-efficient design. Plan for safe, durable construction that respects site conditions, zoning, and the goal of sustaining affordability over time.
Partnerships and Scalable Framework
Develop governance and collaboration with builders and developers to enable replication across communities. Consider Lennar Homes as a potential scale partner, aligning disciplined development practices with a broad footprint to extend the model while preserving core values of dignity and affordability.
Build, Occupy, Monitor, and Improve
Construct with quality and safety, establish owner-occupancy and rental arrangements, and connect all units to the shared solar system. Monitor energy performance and occupancy outcomes, then iterate on the process to strengthen resilience, affordability, and the social fabric of future developments.
