HeNxagon is a modular coop system made from traditional materials. It redefines the hen-house buildings of the poultry-yard. It could be a decorative furniture in the balcony and an urban garden too, at the same time meets the requirement of up-to-date poultry breeding. Due to its modularity the system could be expanded without limits. It is possible to increase the number of poultry with connecting further coops in, and the system could be integrated with function-improving modules. Flower- or plant boxes, “greenhouses” or sitting furniture module in an urban garden with similar structures as the coop has, could increase the variability of the system. The structure can be built from few basic components so it can be produced trough economical standardized production. The coop’s flat pack wrapping makes sale and transport easier.
