ᐅ Semi-detached house – Which type is best? Does anyone have experience with this?

Hello everyone,

I am currently considering building a duplex and am looking for ideas on how it could or should be constructed to ensure a sustainable building in the long term. Of course, it also has to remain affordable.

On the internet and from building planners, you often hear that "this particular method" is the best, depending on the preferences of the contact person. Perhaps someone here can share how they built theirs or what could be done better or differently, so I can get a clearer picture for myself.

Thanks in advance to everyone who takes the time to help!

Best regards,

What do you understand by long-term sustainability? Following KfW regulations? Yes, it is expensive, and whether it is worth it is something everyone must decide for themselves.

Sustainable means durable? Without the following resource consumption? A traditional stone-built house lasts 1000 years with proper maintenance.

What do you understand by sustainable?
Low energy consumption, for example, passive house
Local building companies
Building materials with low resource consumption such as water, CO₂, etc.

The same goes for wooden houses. The oldest house in Germany is a timber-framed building. Whether today’s wood stud constructions with wood, straw, and clay can compare is another question.

Sustainability for me means using as few resources as possible both during construction and living, and if resources are used, preferably renewable ones.

I am open to KfW standards, but it's not about calculations—it’s about actual consumption.

One of my questions is whether to choose masonry or timber frame construction, but if timber is used, preferably with clinker brick exterior.

I would generally prefer local companies and materials with low resource consumption as well.
