Oikos Group

Oikos Group unites the brands Bien-Zenker, Hanse Haus and Living Haus under one roof.

Bien-Zenker, Hanse Haus and Living Haus design, manufacture, sell and construct prefabricated houses in Germany, as well as in Switzerland and the United Kingdom. They are leading German manufacturers of prefabricated houses.

Bien-Zenker was founded over 100 years ago and has established itself as one of the market’s leading and most well-known producers of prefab houses in Germany. The Bien-Zenker brand is aimed at the mid-price range and approximately 30% of the houses it produces are turnkey solutions. Additionally, the brand Living Haus has been introduced to attract customers seeking a price-sensitive alternative, while at the same time maintaining core standards.

Founded in 1929, Hanse Haus was one of Germany's pioneers in the construction of prefab turnkey houses, having grown from a small carpentry business into a manufacturer of high-quality housing solutions, targeting customers in the mid- to premium- price range.

As a result, the combined business is able to offer prefab houses at all levels of completion from a shell to a turnkey house.
