Floor plan draft for a 220m² single-family house

With the flat roof, fear was instilled in many places regarding later moisture damage, etc.

It also depends on the specific house. Some look better with a hipped roof, others with a flat roof. Flat roof definitely only with an overhang. And that way you at least have a setback.

You can never have enough Bauhaus. We just don't like "boring" city villas, purely rectangular with a hipped roof cap and no highlights that make the building look representative.

We would have also chosen the hipped roof for the last design and not the flat roof if the bay window hadn't been there. The edge at the front with the hipped roof is just rubbish.

Some look good with a hipped roof, some look good with a flat roof.

Exactly. And almost no one looks good with both, at least not without adjustments.

Flat roof definitely only with roof overhang.

Nonsense. Bell-bottom pants and platform shoes have long been out of fashion, and the trend for white cars will soon fade as well. The roof overhangs in the "3D" drawings don’t look like they’re supposed to be the house itself, but just a styrofoam model of it. A house should look like it was designed by an architect, not like it was done by a nail designer. House with spoiler

The edge at the front of the hipped roof is simply rubbish.

Hipped roofs can also be shed – however, that is complicated with clad eaves.

Every corner (per dimension) is a critical point. Not only can the structural engineer go on vacation twice this year (not Birgen Air, Egypt), but afterwards a family of building defect restorers will be set for several generations. This is the maximum amount of complications that one can build.

On the other hand, I do not understand that the provider casually dismisses concerns about possible complications. They must also guarantee their work, and if building defects are virtually pre-programmed, they should have an interest in steering the builder in a different direction...

The explanation is extremely simple: he does not have these concerns himself yet. Where should they come from? - this draft is not buildable solely because of the course of the upper floor exterior walls. In times of earlier energy guidelines, that would still have been possible, it would have required exorbitant structural engineering effort. But today, the part of the floor slab that is not covered by the upper floor exterior walls must also be thermally insulated. Not just wrapped in insulation material, but also isolated from the rest of the floor slab. That is practically impossible, which is why they have never been able to build it like that, and consequently do not know the theoretical damages resulting from it.

They must also provide a warranty for their work and if building damages are virtually preprogrammed, one would have an interest in steering the builder in another direction...

At the current planning stage, this is not yet apparent, the relevant specialists were not involved at that time. As soon as the structural engineer takes it up definitively, it will become clear: if you want to stay within budget, their profit is no longer in it. Then they don’t want to do it. The project doesn’t even reach the planner of the "Isokörbe". If there were agreement tomorrow on the final design to be pursued, a call would come within a few weeks: sorry, that just doesn’t work.

Today’s mouse-click architects don’t notice this. When the old pencil veteran says it’s not buildable, they simply think he has not yet reached the year 2000. They only believe the specialist engineer when he shows them the calculation method.

But today the part of the floor slab that is not covered by the upper floor exterior walls must also be thermally insulated. Not just wrapped with insulation material, but also insulated from the rest of the floor slab.

That would be unbuildable. Wouldn't all houses with recesses in the upper floor and, for example, roof terraces be affected? Do I understand that correctly?

No more staggered floors at all? So only congruent floors?
