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.
