Hello everyone,
we are planning to build a single-family house with approximately 160m² (1,722 sq ft) of living space and a basement. We have now received an offer from a developer and had a discussion with an architect. I would like to hear your opinions regarding the masonry.
Developer:
Exterior walls made of Poroton T10 bricks, 36.5cm (14.4 inches) thick; basement exterior walls will have 10cm (4 inches) thick perimeter insulation with a thermal conductivity of 0.035 W/(m·K).
Interior walls: load-bearing 17.5–24cm (7–9.4 inches); non-load-bearing 11.5cm (4.5 inches) brick walls; basement walls made of aerated concrete.
Exterior plaster: three layers—lime-cement lightweight plaster; mesh skim coat; textured plaster finish.
Brick roller shutter boxes; ceiling edges on the ground floor will be finished with brick corbels where possible.
Architect:
Simply recommended brick masonry with exterior plaster containing polystyrene beads.
I hope you can help me here.

EveundGerd25 Dec 2014 22:17The information is sparse. Is this your first offer?
I understand that there are many ways to build a house. We are leaning towards brick and just wanted to hear whether this is considered a high-quality option or more of a budget choice.
We have several offers, but all the others proposed aerated concrete blocks. The information mentioned above only refers to the wall construction, of course, there is more included...

EveundGerd26 Dec 2014 09:58Our neighbors built with brick five years ago. They are satisfied. However, there were some issues, including problems with attaching the baseboards. In the end, the house was covered with an exterior insulation and finishing system (EIFS). I would say it’s a matter of personal taste.
We had a brick wall installed in the entrance area of our existing house as a visual feature. Not all bricks are the same. There are many differences.
If I were you, I would inquire about the specific bricks to be used directly with the manufacturer.
Also, ask people who have already built with your construction company and have lived in their house for at least one winter since moving in.
Keep in mind sound insulation as well. Brick generally provides good indoor air quality, to the best of my knowledge.

We are currently building with Poroton T10 (36.5cm (14 inches)) without additional insulation. With controlled mechanical ventilation, a ground source heat pump, a wood stove, photovoltaic panels, and good windows, we easily meet the KfW 70 standard—even without the photovoltaic system, it’s not an issue.
The information provided by the architect is limited because everything can still be discussed, changed, and customized according to your preferences.
The developer naturally provides more detailed specifications as the basis for the contract.
By the way, I would probably replace the 11.5cm (4.5 inches) walls with 17.5cm (7 inches) bricks or drywall partitions. We have a few of the thinner walls, and when chasing out grooves for electrical wiring, you can really tell they don’t have the stability of the thicker walls. Depending on what will later be mounted on them, it’s better to opt for either thicker walls or drywall.

We will also build with Poroton blocks without additional thermal insulation, but we plan to use the T8 in 36.5. As Milkie already mentioned, with the right technology, it easily meets the KfW 70 standard. In our case, this is achieved without mechanical ventilation, relying only on floor and ceiling insulation. Why do you want to add Styrofoam insulation on the outside as well?
@milkie: Are you talking about your own project now? Would you no longer recommend 11 cm (4.3 inches) interior walls?

I completely agree with Milkie regarding the 11cm (4.3 inches) walls. They are very thin, especially if you want to install water pipes or electrical wiring inside.
We are building with T9 blocks, also 36.5cm (14.4 inches) thick and also without insulation. With a simple air-to-water heat pump plus insulation of the floor slab, we can easily achieve KfW70 standard.
