An eco-friendly, indestructible option. 

Earth first structures

Dens Eco Option offers you the same beautiful minimal living concept built with indestructible, eco-friendly building technology.

All of our Eco Option units are still site-built on a cement slab to deliver the most durable, energy-efficient, and structurally sound products possible. That still means no prefabrication, no manufactured dwellings, and no shipping containers.


However, units are framed with a multi-patented building system that utilizes engineered foam-core panels for all structural elements of the product. The structure is layered with a composite coating made up of a precise blend of sand, cement, fiberglass, and an adhesive that create a building shell that is virtually indestructible.


The result.. a stronger eco-friendly material that delivers a highly energy-efficient and structurally sound home. All while avoiding the use of lumber, insulation, and other environmentally demanding products.

Our products are site built, environmentally friendly, and finished with recycled materials as often as possible. We engineer our eco-option homes to avoid the use of lumber, insulation, and other environmentally demanding materials.

Green Construction

Engineered Foam-Core Panels

We use engineered panels in the construction of our units, utilizing a high-performance building system that stands the test of time.


Each panel consists of an insulated foam core, which is permanently sealed in a concrete-like material to withstand hurricanes, fires, water, mold, termites, and just about anything earth can throw at it.  Our panels are produced under factory-controlled conditions and fabricated to our exact product specifications. The result is a building system that is extremely strong, energy-efficient, and cost-effective.


Building with engineered foam coar panels creates what is ultimately a cement structure with incredible insulation. The structures are strong enough to park a truck on top of, and energy efficient enough to meaningfully reduce your carbon footprint and energy bills.


Added Savings

Electricity & Insulation

With this option, even our smallest Den's have an R-value of 48 and higher, providing meaningful additional savings as it relates to electricity and air conditioning.

R-value is a measure of thermal resistance, or the ability to prevent the transfer of heat. The larger the number, the harder that insulation is working at preventing heat conduction. The less thermal loss, the lower your energy bills.

With this option, each Den has a minimum of 8" of solid foam at the core of each wall at 12' of foam in the ceiling, delivering an R-Value of 48 and higher throughout the unit.


Effective By Design

Efficient Construction

All of our panels and structural elements are designed and crafted to precision before each build during the permitting process.

Upon delivery, every panel is constructed and sealed in place within a matter of days. The structure is entirely sealed in a concrete and fiberglass mix creating a monolithic structure.

Once prepared, each structure is wrapped in our standing seam metal exterior that further increases the Den's durability and resistance to weathering.


Eco-Friendly Homes

Everlasting Products

At the end of this process, our customers are left with a beautiful, functional, eco-friendly dwelling that used zero lumber in construction and has an incredible energy efficiency rating.

This option results in an indestructible structure that will stand forever, all while saving trees and energy.
