Built for Forever

Tested, engineered, and licensed.

ELMNTL

Built for the planet

Our wood structure and hemp insulation produce 3x fewer carbon emissions than steel frames with traditional insulation. At ELMNTL, we care about the end of our products' life cycles. Our materials are designed to be reused or composted.

Built for extremes

ELMNTL Shelters are designed to withstand extreme conditions. They are outfitted with class A fire-rated, fireproof exteriors that can withstand up to 195 mph winds. With a snow-load capacity of 100 lbs/sqft and a water-tight envelope, ELMNTL Shelter provides tested refuge from the storm.

Built to outlast

ELMNTL Shelter is backed by a 10-year structural warranty and a 2-year systems warranty. We've designed, engineered, and built with longevity in mind. Until you choose to dismantle it, our structure will stand solid through the elements.

Built to perfection

Our team merges the artistry of fine furniture craftsmanship and the precision of boat building to craft stunning structures. We believe that a lifetime investment deserves timeless craftsmanship that you can admire for years to come.

Built for the wild

Go off-grid, unplug, and truly immerse yourself in the elements. Floor-to-ceiling windows invite in the views and natural light. Add a rooftop or traditional deck to elevate your time outdoors. And you can go off-grid with ELMNTL Shelter's off-grid system package.

Innovative Living: The Rise of Accessory Dwelling Units

As housing trends evolve, accessory dwelling units (ADUs) are becoming an increasingly popular solution for maximizing property value and providing flexible living spaces.

Whether you’re looking to create a rental income, accommodate an extended family, or add a home office, ADUs offer a versatile and efficient option. Here’s a comprehensive look at why ADUs are transforming the housing landscape.

Benefits of Accessory Dwelling Units

1. Increased Property Value Adding an ADU can significantly boost your property's value. These units provide additional living space that can attract potential buyers and increase the overall marketability of your home.

2. Versatility ADUs can serve various purposes, from rental units to guest houses or home offices. This flexibility makes them a valuable addition to any property, catering to changing needs over time.

3. Income Potential One of the most appealing aspects of ADUs is their potential to generate rental income. By renting out the unit, homeowners can offset mortgage costs and create a steady revenue stream.

4. Efficient Use of Space ADUs make efficient use of existing property space. By building on unused land or converting existing structures, homeowners can maximize their property's potential without the need for extensive expansion.

Design Considerations

1. Space Optimization Effective space optimization is crucial in ADU design. Open floor plans, multi-functional furniture, and built-in storage solutions can help make small spaces feel larger and more functional.

2. Privacy and Accessibility Ensure the ADU provides privacy for both the main residence and the unit's occupants. Separate entrances, soundproofing, and thoughtful placement can enhance privacy. Accessibility features should also be considered, especially if the unit is intended for elderly family members or individuals with mobility challenges.

3. Sustainable Design Incorporate sustainable design elements to make the ADU eco-friendly and energy-efficient. Solar panels, energy-efficient appliances, and sustainable building materials can reduce the environmental impact and lower utility costs.

4. Aesthetic Integration Design the ADU to complement the existing home and landscape. This ensures a cohesive look and feel, enhancing the overall aesthetic appeal of the property.

Practical Tips for Building an ADU

1. Understand Regulations Familiarize yourself with local zoning laws and building codes. Regulations can vary widely, so it’s important to ensure your ADU complies with all legal requirements.

2. Budget Planning Develop a detailed budget that includes all costs, from design and construction to permits and finishes. Careful financial planning can prevent unexpected expenses and keep the project on track.

3. Professional Assistance Work with experienced professionals, including architects, builders, and designers, who specialize in ADU construction. Their expertise can help streamline the process and ensure high-quality results.

4. Future-Proofing Consider future needs when designing your ADU. Flexible designs that can adapt to changing circumstances will provide long-term value and functionality.

Accessory dwelling units are revolutionizing the way we think about property use and living spaces. By offering a versatile, efficient, and valuable solution, ADUs are meeting the needs of modern homeowners and contributing to innovative housing solutions.
