Actually, as a representative of the timber house faction, I should fully jump on this drying train, but somehow the topic is slowly becoming outdated.
The ones at V are simply tightly organized and always work within the same system, which is why they are so fast. For example, windows come in standard sizes and are not measured on site, the same applies to other components such as roofs or bay windows. In this way, you can save time compared to smaller conventional companies. Interestingly, they build their "solid house" in the upper floor/attic routinely out of wood...
Water in construction? Where does it actually come from? There is no more mortar joint, everything is glued. And even when it rains, a modern T9 brick can hardly store water, as the brick consists mostly of insulation and hardly any water-retaining mass is present. With gypsum plaster, water is negligible in my opinion.
Basically, only the screed remains, and there are quick binders for that. While I am not a fan myself, it's for other reasons; the chemistry in it should be harmless. After all, the stuff needs German approval and the criteria are very strict. Also, I cannot avoid chemicals in a brick house, as the adhesive between the bricks also contains some.
Once you have found the right builder for you, time should generally be secondary. Whether 8 or even 14 months pass from purchase to moving in is actually irrelevant if everything else fits.
