Hello everyone, I hope some experts here can offer me some advice. We are about to start building a single-family house. We have received several quotes from different construction companies. Each company recommends a different type of exterior wall construction, so I would like to ask for your opinion.

I am aware that this topic has been discussed many times before, but I can only find outdated information online.

The house will be built in Fürth (Bavaria). The location is relatively quiet, but there is a highway about 400 m (440 yards) away, which is barely audible from outside. The interior walls are planned to be made of sand-lime bricks.

The following materials have been proposed for the exterior walls:

- 36.5 cm (14 inches) aerated concrete (0.09)
- 36.5 cm (14 inches) porous fired clay bricks (0.10), laid with lightweight masonry mortar LM 21
- 17.5 cm (7 inches) sand-lime bricks combined with an external thermal insulation composite system (ETICS) of 150 mm (6 inches). This involves attaching rigid foam panels with a fiberglass mesh reinforcement layer to the outside of the masonry.
- Poroton T8, T7
- Liapor SL, Liapor, Super-K-Plus, etc.

I would appreciate any help and advice in making this decision.

Thank you in advance for your valuable support!

Ideally, you first decide on the construction method and then look for the appropriate craftsmen. Only if there are other constraints should you adapt to the construction method of the selected general contractor / developer.

Especially since there are many general contractors who do not build themselves. They simply look for the cheapest construction company to complete the shell structure.

It is a myth that general contractors always work with the same tradespeople. They also choose the cheapest tradesperson available at the time.
