Joint building venture

Two modern semi-detached houses, one building partner

Baugemeinschaft im Schwörer-Haus

Using the example of the Schweiker and Riegsinger families

Childhood friends club together – the Schweikers and Riegsingers. “We had never planned to build our own home“, says Jan-Uwe Schweiker, “but at some point we realized: the money we were pouring into paying rent could also be paying back a mortgage on our own home. At the end we would have something we could call our own“. Yet he and his wife didn’t want to live on their own. Finally they have realized their dream of sociable living – and now share a contemporary, child-friendly semi-detached house offering country house appeal with their childhood friends.

Our prefabricated houses at a glance

Single-family homes

Single or two-storey, with gable, hip or flat roof, as an urban villa, country house or cube – we implement your individual single-family home for you.


A light, airy living ambience, direct access to the garden from all rooms – living on one level has its appeal. Bungalows are single-storey houses with many possibilities.

FlyingSpaces: Tiny Houses

FlyingSpaces or Tiny houses are high-quality modules that work as an entire mini house, single-room extension or even in combination.

Semi-detached houses

Semi-detached houses are a good alternative, when construction density is concerned. The construction of semi-detached and terraced houses is of interest for inner-city plots in particular.

Houses with an annex

Do you want a second, self-contained residential unit within your single-family home, so that you can rent it out or have grandparents or adult children in the house?

Multiple-family homes

Are you looking for a secure, long-term, low-risk investment? From a financial and strategic perspective, investment in a multiple-family home is worthwhile.
