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.
