Off-Grid Prefab zeroHouse Now Ready!


Two years ago, the zeroHouse hit the internet like a tornado.  Now, Specht Harpman, the firm that designed the off-grid, modular, tiny house, is looking for a "visionary" to finance the construction of the prototype at something in the range of $300,000 to $350,000.  The good news comes from the American-Statesman, which recently reported that the design is "shovel-ready." 


According to the American-Statesman, Specht Harpman used seed money from a New York investment firm to create architectural, structural, and mechanical engineering documents.  Now the zeroHouse is ready to be built, and the idea with the first home is to push the boundaries of sustainability. 

The zeroHouse can be net-zero energy — it'll generate as much energy in the course of a year as it consumes.  It can also operate without the need for any external utility or waste disposal connects.  

Of course, the 650 square-foot home doesn't buy into the cost per square foot mentality.  It's well designed and square-footage is created with caution.  That said, the architects believe zeroHouse can easily accommodate four adults. 

Green elements planned for the home include a wing-like solar array, four 550-gallon rainwater cisterns, triple-paned windows, a high-efficiency HVAC system, durable and natural materials, high-efficiency electronics and appliances, and a helical anchor foundation that hardly disturbs the earth.

    This looks fabulous, love it! Um, concerned about the wind though – I guess it is not suitable for a cold/windy location…

    I absolutely love small homes. If it were in a rainy area, I would definitely live in one.

    i understand the elcetricity factor in all these netzero homes. What i don’t understand is the water. I see the description states (4) 550-gallon cisterns (not shown) but how would this concept generate potable water? Plus, is the water recycled or disposed after use? it would take a lot of rain to fill those cisterns.

    this is a great home for now
    need many ;so we won’t need the utilities from any co’s.

    Why in the world would this need to be priced in the 300-350K range. Especially during a recessikon. This should cost no more than 20k.
