SB1 & SB2 FAQ

What's a Sparkbox?
​Sparkboxes are a type of Accessory Dwelling Unit, sometimes called in-law unit or granny flat, that sits on the same lot as a single-family home. Sparkbox is versatile space that can be used for housing, creative studios, remote work space, fitness and well being, and more - all in the convenience of your own backyard! It's a great option to rent out for additional income or provide extra space for friends and family.
What does "off-grid" mean?

I cut the cord, now what?
Thank you for contributing to the well being of our environment, and welcome to off-grid living!

The solar array on your Sparkbox provides high amounts of power. Sparkboxes are powered by Discover Batteries, the North American leader in safe lithium battery technology for over 70 years. Your Sparkbox will have ample electricity to operate multiple appliances and electronics.
How do I heat and cool my Sparkbox?
Mini splits are more efficient than other heating and cooling systems. Sparkboxes come equipped with a remote controlled mini split that can seamlessly integrate with any smart device.
Why shipping containers?
Our team has been working with shipping containers since 2016. Corten steel, one of the strongest materials available, is weather resistant, durable, and will not rust through. Over time, the containers will develop a natural patina, reflecting the environment in which it's placed.  Each Sparkbox repurposes over 12,000 pounds steel.
Where is it built?
Sparkboxes are built in Arizona at our state certified fabrication shop. Steel and Spark carries multiple licenses including contracting, manufacturing, dealer, and installation.
