When you order a Mighty Small Homes kit, you receive the exterior shell to get your new home under roof and insulated, plus lumber to frame the interior. You (or a builder you hire) then assemble the home on site and finish the interior and exterior to suit your personal taste and budget.

Here’s a step-by-step guide to how it works:

Step 1: Pick your style and size

From a cozy cottage to a spacious modern home, our small home kits come in a wide range of styles and sizes. We can also do custom designs or customizations of the models listed on our website. In spite of the names, our kits really are a blank canvas. For instance, you could add Victorian touches to the Cottage or go midcentury-modern with the Ranch.

Step 2: Choose options and upgrades

All of our tiny and small home kits include the core materials needed to begin construction on your new home: precut exterior wall and roof panels with window and door cutouts, electrical chases through the walls, building plans, fastener, caulk, house wrap, and even some tools. You can also choose upgrades like doors, windows, sidings, lofts, porch, roofing materials, thicker panels (great for cold climates), and additional electric chases.

Step 3: Choose a standard or custom interior floor plan

Knowing how you want to finish the interior ensures that we cut the exterior door and window openings in just the right locations. Therefore, we include an interior floor plan with each kit.

Some of our standard floor plans are featured here on our website. If you want to make tweaks or start from scratch, we can create custom plans for you at no charge.

Step 4: Prepare the building site

Before assembling your new Mighty Small Home, you will first want to ensure that you have a solid foundation prepared. More than likely, you will build your Mighty Small Home on a slab, crawl space or basement. We’ll send you engineer-stamped blueprints ahead of time so you can pull permits and prepare the site. You will also want to have a standard set of construction tools available to supplement the SIP tools Mighty Small Homes will provide (see what we provide).

Step 5: Unload your kit and review the blueprints

Your kit will be delivered on a flatbed semi. You will have 2 hours to unload once the truck arrives, so be sure to have your equipment and crew ready to go. Your blueprints should be ready to use upon delivery. Review the plans carefully so you can orient yourself for the direction of the house. Also note how each section of the kit is numbered on the plan. That number corresponds to a number on a panel.

Step 6: Assemble your home’s exterior shell

Select two corner panels to start. We suggest starting on the far side of where your panels have been placed so you do not have to carry panels around other panels that have already been set. As the panels go in, just line them up, seal the joints with caulk, and nail them into place.

If you’re building a tiny home on a trailer:

It is important to note that building on a trailer must be done with extreme caution. Be sure everything is adjusted and squared with the trailer for security. Remember, you want your trailer to be just as stable as any other foundation you might normally build on.

Step 7: Finish the exterior and interior

With the shell completed, you can focus on getting your home “dried-in,” by installing windows, doors, siding,
and roofing.

Since the outer shell goes together easily, time and energy normally spent completing a building project can now be used focusing on the exterior and decoration of the home you’ve always imagined. If you possess the skills needed to remodel a house, you should have the necessary skills to complete your Mighty Small Home.

One note of caution:

Be sure to recognize your limits and seek professional assistance if needed for projects such as plumbing and electricity. Even if you are capable of completing these tasks on your own, we highly recommend having your work checked out by professionals. Permits and inspections may also be required depending on your location.
