Do you want to enlarge/extend your house?​

Conversion and extension of a Schwörer house, year of construction 1978

The young Schmitt family moved into the parents’ house in 2006. At that time, the young couple lived on the ground floor and the parents moved into the attic. Initial modernisation work was ordered from SchwörerHaus.

When the family of four reported that they needed more space, the decision was made in 2019 to have an extension – executed by SchwörerHaus.

Complete modernisation: Example of the Kinzelmann customer house


Do you want an accessible conversion for your house?​


Conversion of a Schwörer house, year of construction 1991, wheelchair-accessible and comfortable.

Owing to a motorcycle accident, the Bambach home needed to be made accessible during a long stay in rehabilitation. The modernisation work was undertaken in consultation with the building owners, insurers, an architect and local tradespeople. The planning was configured to achieve an individual nature for the house and the greatest possible independence both in the house and in the outdoor area.

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.
