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,
Dirk78

Hello everyone,

I’m joining the conversation because I’m currently wondering about the choice of material and construction method.
I’m new to the forum and in the process of planning a house.
I already have a quote that includes exterior walls made of 36.5cm (14.4 inches) Poroton blocks without external insulation, just plaster.
Does that make sense, or would you advise against it?

With this type of construction, would you recommend reinforcing the exterior plaster to prevent possible cracking?
I’m looking forward to your opinions.

Best regards,
Alex

The exterior plaster will have, and must have, reinforcement.

It reads in my scope of work as follows:
For the exterior plaster system, a lime-cement plaster with a thickness of 1.5 cm - 2.0 cm (0.6 - 0.8 inches) is applied onto the Poroton masonry. On top of that, the finishing plaster is applied as a 2 mm (0.08 inches) synthetic resin plaster.

Reinforcement is specified only for the version with external insulation in the scope of work, which does not apply in our case.

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

I respect your Nordic humor, but I can’t imagine how a house made of 10cm (4 inches) thick glued-together small stones and fully clad with 50cm (20 inches) of expanded polystyrene insulation around the exterior, including all the plastic waste inside, could still stand after 1000 years like a medieval castle from long ago…. This myth about "massive houses" reminds me a bit of the Nordic cars made from so-called "Swedish steel"... that was a long time ago.

Then just skip the styrofoam mess, build monolithically, and cover the whole thing with brick facing. Why shouldn’t that last at least somewhat forever?

Now I’m curious…

I just finished reading everything. I noticed that some questions directed at you were not answered. These are necessary to provide you with more precise replies than your original questions.

I’m happy to be proven wrong! If the result of a renovation can match that of new construction… why not!

Low energy consumption means (to me) that the energy doesn’t even have to be generated in the first place?!

Is this thread now hijacked by you, or do you, Dirk, use two usernames? It’s a bit confusing.

Even more confusing is a post that either stands on its own or should be answered via search.
Hijacking threads is rude… Your question has little to do with the topic “sustainable semi-detached house,” which is more about fundamentals.
Why don’t you start your own thread? It won’t hurt, even if we bite.
