Semi-detached house as Efficiency House 40 Plus

Energy-efficient combined with high living comfort

Doppelhaushälfte Landhaus

The Denlöffel family as an example

Ecological timber construction, energy efficiency and high-comfort living in a compact space. In the Allgäu, Schwörer construction advisor Christoph Denlöffel has built a semi-detached house as a KfW Efficiency House 40 Plus for his family of four. 21 PV modules on the roof, an energy storage system and extremely well-insulated walls make this semi-detached house a KfW Efficiency House 40 Plus. The regulated ventilation with heat recovery ensures a pleasant indoor climate at all times.

Semi-detached house: advantages

Semi-detached house: pictures

Mr Denlöffel enjoys giving interested visitors a tour through the modern semi-detached house so they can see the excellent quality of the SchwörerHaus for themselves. „It’s impressive to see how much space the classic pitched roof house has to offer.“ His wife, Jenny, is thrilled with the healthy indoor climate thanks to regulated ventilation and the low-emission construction methods practised by SchwörerHaus. The highly heat-insulated building envelope and triple-glazed windows means that the KfW Efficiency House 40 Plus does not need any conventional heating.

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.

Bungalows

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.
