since we are about to start building our new flat-roof house, we wanted to ask for your advice on which materials you would use (aerated concrete, filled or unfilled fired clay bricks, calcium silicate bricks, etc.), what wall thicknesses, and whether to use external thermal insulation composite systems (ETICS) or not—and why?
We plan to heat with natural gas, which will make things more expensive.
External sound insulation is not necessary, as we are building at the edge of a forest / town outskirts on a dead-end street. Soundproofing inside the house might be more important due to children and night shifts.
We only want to meet the minimum requirements of the 2016 energy-saving regulations (no subsidies from KfW or similar), aiming for the most cost-effective and as slim a construction as possible—although the latter probably conflicts with the former?
The double garage attached to the house should also be built with solid construction—what materials would you recommend there?
Thanks in advance!

I always reply the same way, as you can find in any thread on this dispute by using the search function:
Find a suitable contractor and let them build in the way they know best. No type of brick or block is inherently bad, and there is no “magic” material either. Doing it the other way around—choosing a specific brick first and then looking for a contractor—is putting the cart before the horse. Insisting on a particular brick while knowing the builder has much more experience with a different one increases the risk of poorly executed component connections.
In terms of wall thickness, it’s almost a zero-sum game whether you build monolithically with 36.5 cm (14 inches) walls, or use 24 cm (9.5 inches) brick plus 12 cm (5 inches) insulation, or 17.5 cm (7 inches) brick plus 16 cm (6 inches) insulation.
A garage is a functional structure; its walls support the roof, while climate control is secondary.

Every general contractor and architect has their preferred construction method...
And honestly: most of the time, the overall package including price is the deciding factor... you don’t really ask about the pros and cons.
You gladly go with the construction method of the contractor or architect if everything else fits.
We have ETICS (External Thermal Insulation Composite System)... otherwise, we probably would have built monolithic without this insulation if the price hadn’t been higher.
