What is 

FIREFLY?


It's a series of building blocks that can be put together to create or add to any small space. 


Full-time living

Our systems are designed for rigorous full-time use, unlike standard vans, campers, and some tiny homes.


Easy to assemble

We design our systems to be easy to put together, even if they are custom designs.


Future-proof

Our systems are designed to be easily maintained, upgraded as new technology comes out, and - if needed - repaired.


Safe Materials

We do our best to pick the safest materials - the ones that are non-toxic and do less harm to the planet.

We've lived in small spaces for years, so we designed the systems we wished we had when we started our journey. 
-Avriel Co-Founder of KLS
