ᐅ Brick masonry

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.

And the question would be?

What do you think about the developer’s execution details and the architect’s statement?

Are these specified implementations reasonable, or is there anything that could be planned better?

Useful in what respect? In principle, you can certainly build a house with it.

Reasonable for a single-family house, or how would you build it?
The KfW efficiency standard should be around 70-85, the residential area is rather quiet (sound insulation), otherwise just normal requirements.

There are more than two dozen practical ways to build a single-family house (at least for the walls alone). Usually, personal preference also plays a role (wood/brick/monolithic construction or not, etc.). Your option sounds feasible; depending on other features and construction methods, achieving a KfW 70 energy standard is definitely possible, I would say.
