Building a prefabricated two-family house with a living area of 187 to 257 m²
Two families under one roof – with our Duo house series we present very different prefabricated house designs with two living units. Whether as a multi-generational house, for friendly families or with a separate flat to rent out: A two-family house can be used flexibly and planned just as individually. The two flats can be roughly the same size and arranged next to each other, or one above the other and share a common staircase. In some of our two-family houses, a granny flat is assigned to a "main house".

What are the advantages of a prefabricated two-family house?
Advantages
As diverse as two-family houses and their possible uses are – they all bring some advantages for their residents. Do you attach great importance to sustainable building and would you like to benefit from the advantages of a residential community? Then a two-family house is just the thing for you.
Sustainability
The two-family house is a sustainable concept:
- Two families find space in one house, so that valuable building land is used sustainably.
- In terms of environmental compatibility and energy efficiency, the two-family house is convincing - especially in sustainable prefabricated timber construction. Due to the interface with the second residential unit, less heating is required overall and heat loss is minimised. The lower energy consumption conserves resources and reduces running costs.
Support in everyday life
Shared apartment in a two-family house:
- You can choose your nearest neighbours yourself. Despite all the proximity, the two-family house offers private retreat options.
- Especially in a house for generations, living together can be enriching. The shared apartment offers wonderful moments with the family. In addition, it can provide relief in everyday life: the older residents receive support in the household or with errands, for example, and help out with childcare themselves.

Individual planning
The flexible planning options are one of the greatest strengths of our two-family houses: the right two-family house floor plan can be found for every living constellation. Our draft proposals show how different this can look.
If you build a two-family house, you don't have to compromise on the architecture. A second living unit can be accommodated in a classic city villa as well as in a modern extension with a flat roof.

Living on top of each other in a two-family house
Two flats on
two floors
In the classic two-family house, the two residential units are often arranged one above the other, so that each party occupies its own floor. A common entrance to the house leads to a staircase with access to the flats.
An urban villa with two full storeys offers the best conditions for planning two similarly sized living units on top of each other in a two-family house: without sloping ceilings, a spacious flat with full room height is also created on the upper floor.

However, the two residential units can also be located next to each other in a two-family house and share the utility and technical room, for example.
Our generous Duo 229 design shows how a smaller, single-storey flat can be accommodated next to a larger "main flat" in a two-family house. Each of the two residential units has a separate entrance to the house.

Own area in the common house
Living together in a two-family house while both parties have their own area - this can be achieved, for example, by moving the second living unit into an annex.
This solution can be flexibly adapted according to the conditions on the property and the wishes and needs of the residents.
Two living units, many possibilities with your prefabricated two-family house

Our builder lives with his spouse in 138 m² and has rented out the 73 m² second flat to friends.
„Since we planned the house from the outset for us and a family of friends, the floor plan was adapted to the wishes of both parties.“
