Structural shell / Structural shell cost calculation - How does it calculate?

Basically, the drainage should work. The downpipe does not have to go directly vertical; it can initially run with a slight slope in the ceiling. However, a kink in between is not good, but I don’t see that in your draft anyway. Is the sewer at the end of the pipe as well? Regarding your expectation to save money through your 'pre-planning' with the architect: the opposite is the case. Instead of being able to start from scratch with a room program and development plan, he also has to somehow take your already quite detailed ideas into account. Honestly, I would let him start from zero. Then take a look at his drafts. If you then come to the conclusion that yours is better, you can always bring yours out. If you are already fixed on your plans and are sure that they comply with the development plan, you are better off with an authorized draftsman who will only do the execution planning for you.

I really had to look closely to see where the newer plan differs. When it comes to draining toilets, forced ventilation always plays a role; and it goes up through the roof. Or through the rooms above. And one green shaft is not enough for all kitchens and bathrooms.

But that is only one issue that was noticed. Structural engineering is also not considered. Sometimes walls are not aligned, etc.

And the fact that the basement garage is rotated 180 degrees on the plan does not help with the assessment.

Regarding saving money on the architect. Unless he is a specialist of yours, he will likely charge you more. At least I wouldn’t know why he should accommodate you.

Hello,

that's exactly how I have done it so far. I found a [bauvorlagebrechtigen Bauing.] who prepared the plans for little money in pure form. The [BA] is currently ongoing. It is a 34er (no development plan).

Unfortunately, the attic floor must be recessed. That makes drainage a bit more difficult. The offset is 1 meter. By this amount, you have to extend outward in the ceiling... the windows below must also look different...

I need ventilation for every connected pipe, right?

Statics: a local structural engineer assessed it --> the displacement in the load-bearing walls is not a problem
Architect: I have someone who understands SketchUp (my software). He takes my model and transfers it to CAD
Layout ground floor: you are right. Will be adjusted..

Hello,

attached is the new draft. Floor plans are rotated. I have changed the windows regarding the drainage of the WC in the attic. We want to build with Neopor formwork stones. The drainage pipes should be cast in with it. Rainwater stays outside.

I am currently dealing with the parapet on the roof terrace. The insulation and sealing membranes should continue... this raises the question of anchoring the parapet...

maybe someone here has a tip as well...

Best regards, Alex

So the internal drainage doesn’t make sense at all. Here are a few examples:

[*]Is the wastewater from the bathroom in the attic supposed to run into the bed below? Wastewater pipes are never routed through exterior walls. They are always in partition walls and supply channels/boxed-in sections. I don’t see anything like that in the bedroom below.
[*]The same applies to the kitchen in the attic. There is a bathroom underneath, but the top side in the plan looks more like a half-height partition wall.
[*]In the second bathroom (the right one), either two drainpipes are now necessary (for the toilet and washbasin; as well as for the shower/tub). This is because there is no room around the corner intended for a partition wall; at the same time, there is no boxed-in section above for venting; but that would be necessary in this work niche.
[*]The kitchen stack on the right in the upper floor lets its pipe appear in the roof terrace?

At the moment, I see 5 drainpipes going down to the garage level. 4 of them would have to be vented by force. I don’t see any of that in the plans.

And that really affects your plan, because these boxed-in sections partly make furniture placement much more difficult; at the same time, they don’t look aesthetically pleasing in the intended locations.
And the windows in the attic in the work corner wouldn’t be feasible either.

We haven’t even started with electricity and heating....
(for example, a sub-distribution board is necessary for the small apartment, with the required circuit breakers for the apartments. I don’t see space for that anywhere)
