Floor plan of a bungalow with 140 sqm - does the storage space fit?

You should definitely discuss the topic HAR and bathrooms with the entrepreneur again. In my opinion, the entrance door should be moved towards the north and hinged on the left.

So bad, I did not expect that,

Yes, sure – just for the fun of pedantry I wouldn’t have to get so riled up about the botched mason’s bags. Rather, mainly because of the causally initiated problems with the bonding measurement (before the bricklayers make a puzzle out of it, the stone last laid in the respective course is simply cut and mortared into the normally dry intended head joint. Naturally, the cutting is not done with watchmaker precision, and consequently, correct procedure happens at most by chance and only occasionally. Planned rhythm-wise, masonry is at least on the long run an unskilled labor activity, meaning the qualified specialists make the corners and can then leave the rest to helpers. For fantasy measurements on the other hand, you basically have to look over the executing worker’s shoulder permanently. And all this only because today’s architect youth do not consider mastering the small eight-over-eight necessary. They just plan digitally as if masonry were not an analog action. And as a second reason I react allergically to this because this laissez-faire is usually not selective but representative. Therefore I see – unfortunately regularly confirmed by experience – the octameter ignorance as an indicator not to adequately observe the regulations (mortar application how, which mortar for what) when mortaring either. The “patchings” of the otherwise actually dry head joints are regularly carried out with the same mortar already on the trowel for the bed joints of the next stone course anyway.

our GU knows the octameter and consistently forced us into the grid, statement, he doesn’t build otherwise

That pleases me. How does he deal with double walls in that case?

That really doesn’t sound good... So now a course reversal and consult architect and building authority again? Or watch more closely during the bricklaying with specialists?

No, you still haven’t understood. You can be completely relaxed when it comes to bricklaying. The “wild bond” is practically already “set” here, and most clients like it best anyway. Here it can not only be easily compensated but is also technically unproblematic. Where one must look especially suspiciously if avoidable is the masonry of the inner (i.e. actual) wall shell. I don’t understand course reversal and building authority: is the planning already approved, so our discussion is actually pointless?

Such changes to the house you can always take into account during execution planning. As long as you do not compensate into the clearance areas this should not be a problem.

Exactly, so my suggestion Plan A would be as said the adjustment of the dimensions (also in the overall dimension of the house to, as said, 17.115 or 17.24 instead of 17.15 meters length (so 3.5 cm less or 9 cm more, the latter would be my preferred variant), for the other three house sides you can gladly contact me. Plan B would be to triple the control density of the expert during the shell construction with the fantasy dimensions – as said, avoidable if the architects took their training more seriously.

I'm glad to hear that. How does he handle cavity walls in that context?

The general contractor does not build cavity walls,
he only builds with Liaplan expanded clay blocks,
and uses a program during planning that provides him with the parts lists of the blocks, which are then pre-assembled for the construction sites at the block factory.

Did you nail OSB boards fully across the entire roof directly onto the roof beams? I was strongly advised against doing that from all sides (roofer, construction manager, drywall installer)...

Just want to quickly answer the question.. We have a concrete ceiling. Beams were laid on it to attach the OSB boards. Thick insulation was applied to the concrete ceiling.

Ok, understood! We already have the building permit as stated in the initial post. Therefore, the question is how to deal with it.

It's an important piece of information, so that no one copies it who only has a suspended ceiling with a vapor barrier.
