weeHouses, created by Alchemy Architecture founder Geoffrey Warner, creates prefab modular homes based on weeHouse "modules". He created the first weeHouse in 2003 and since has developed a flexible system of employing modules alone or in combination with other modules or "companions" to create a spectrum of flexible, prefabricated homes.

weeHouses are available in "mass-produced" standard models (Studio, Pair, Tall and Four Square), and as Custom weeHouses, or Custom Projects.
