Build an ADU Small Home with RHINO’s Steel Building Kits

Small homes have become an increasingly popular way to live and host. with ADUs like backyard suites, granny flats, or guest houses. These small houses are considered ADUs, or accessory dwelling units, if they are built on the same property as a preexisting home. So a small studio in the backyard would be an ADU. If you’re looking to make your own guest cottage or in-law suite, RHINO’s steel building kits are perfect to build a sturdy, easily maintained, and singular small home for you.

What Kinds of ADUs Are There?

There are a few different types of ADUs. Technically, one can convert interior spaces or wings, even the garage into an ADU, so long as the space is sufficiently partitioned off. Generally, though, when thinking of an accessory dwelling space, we picture something outside and separate from the main home. There are attached ADUs, which can be built onto the side of a house with its own entrance. RHINO’s lean-to structures work well for this. Then there are completely detached ADUs, which are completely standalone structures, and can be built however you like.

Things to Consider When Building an ADU

As you start designing your small, ADU home, there are a few things to keep in mind. First, you’ll need to be aware of permits and building codes for your area. RHINO makes this as easy for you as possible by ensuring your metal building kit meets or exceeds all local codes. As for the actual design and size, consider the purpose of your ADU. Is it primarily for short-term guests? Or for the grandparents to come live in. These will determine your design needs.

Benefits of a Small ADU for Your Guests

The idea of a guest house or long-term host ADU may seem daunting, but it does come with benefits. These small homes are more affordable than most normal homes, since they have reduced insurance and smaller utility bills, and will save your guests hotel costs. Maintenance is easy since there is not much to maintain — using a steel building would reduce maintenance even further — and the lower need for energy and water means a more sustainable way of living. Not to mention that having your guests and family members living so close means easy access to the people you love.

Common Small Home Problems You Can Avoid with Steel Building Kits

Of course, not everything about living or staying  in a small home like an ADU is smooth sailing of course, but many of the common issues can be prevented by opting for a steel building kit instead of traditional construction methods. Small homes are prone to weak frames, ventilation problems, poor insulation, leaks, and general vulnerability to severe weather. Using a RHINO metal building kit gives you Pro-Value Insulation, overlapping panels, and other weatherproofing features. And they are still just as customizable as any other construction method.
