Many tiny houses are built conventionally with inefficient and toxic materials that off-gas chemicals during installation and surely for much longer. The tiny house movement is quite young, and the building methods are consistently progressing. Only five years ago it was common to build a tiny home without plumbing; now that’s unheard of. 

Stories of mold growth on window sills, under mattresses, in subfloors, and in the walls of tiny homes are beginning to pop up everywhere, no matter the climate they are in. Most tiny houses are not built with proper ventilation or moisture control. Walls are built thin (2×4) to save on interior space, and by doing so condensation within the wall systems and subfloor (trailer) is inevitable, and mold growth is pervasive.

Additionally, tiny homes are built super tight. Without open windows in the winter, one average sized person will consume the air in an average sized tiny house in 8 hours. If multiple people and animals live in a tiny house then that time decreases considerably, making each inhabitant recycle each others’ exhale. Not only is this less than ideal, but it also creates massive amounts of moisture that settle within the ceiling and wall systems. It’s possible to build differently and in a way that takes these issues into consideration. It’s important to build a high performing tiny home that functions efficiently and lasts as it’s intended to.

A Tiny Good Thing has teamed up with a Passive House Design (green building) company to put together materials that allow moisture to escape the wall systems, while simultaneously keeping moisture out. Everything done in a large house is condensed into a tiny home. Propane appliances, cooking, bathing, and breathing all create significant amounts of moisture, and the current conventional building standard for tiny homes doesn’t address the moisture load.

It’s possible to build in a way that keeps the health of the inhabitants and environment in mind. The new wave of the tiny house movement and building at large is moving in a more ecological direction. It’s now time to go a step further. So, become educated, make smart choices, and build HEALTHY.
