Exterior Saltbox Roofline Tiny Home Prefab Design Photos and Ideas

In thinking about the worldwide lack of reliable water, sanitation, food, and electricity—and the fact that housing sector contributes more than a third of global greenhouse gas emissions—the Yale Center for Ecosystems in Architecture and the New Haven, Connecticut–based architecture firm Gray Organschi Architecture designed and constructed a 230-square-foot home called the Ecological Living Module (ELM). The construction is a fully off-grid housing prototype that was designed to take advantage of sustainable materials, green technology, and simple construction methods. There's a a rainwater harvesting system, a solar system that provides 100 percent of the building’s energy needs, and a graywater system that irrigates food-producing plants that mark the building’s west facade.
The Ecological Living Module (ELM) was installed at the UN Headquarters in New York City for two months.
The home's modular design is composed of an outer shell and an interior core unit that contains essential living functions, such as a bed, bathroom, and a small kitchenette.
Because the unit was temporary, it didn't follow the typical permitting process of a micro-unit or home in New York City; what's more, because it was installed on land owned by the United Nations, local and federal codes and permits did not apply.
Manufactured in a factory offsite, the 370-square-foot house can comfortably fit two people.
