Hello, after everything that has already been written here, one thing is still unclear to me, why do you want a flat, earthy plot? Wouldn't a hillside location be more sensible? There you could then reach the ground floor at ground level, which could greatly accommodate your mobility, and place the garage on the ground floor. Set the entrance to the basement on the side. You wouldn't have to excavate the entire plot, which also represents a huge cost issue; alone transporting the excavation material and landfill will cost you a fortune.

I am also not sure if the excavation will be approved by the building authority without further ado. And still, only about 2/3 of the basements may remain free-standing with 2 full floors. You should consult the building authority first because it could be that they count it as three full floors in your case.

Good evening,


The UG clearly has separate areas (attachment). A hallway area that opens access to the utility rooms as well as to the granny flat. The only overlapping area is the hallway. In other words, anyone coming from the ground floor into the utility rooms "does not disturb the parents-in-law and vice versa."

The OG does have a hallway as a distribution center; equally, the hallway is also used somewhat privately by the children, for example when they "visit" each other. If the children’s rooms were separated like the granny flat in the UG, they would have their completely own area; for instance, they could walk naked through the hallway without having to expect that someone from the ground floor or the granny flat could watch/disturb them. Children do grow older and sometimes have visitors at night :D

Rhenish regards

" : I am a mathematician, not an artist. I probably couldn’t distinguish a house with an “a-basic idea” from one without, but I am willing to learn."

Good! So a mathematician. Let us now set aside the discussion about the functional aspects of the floor plans. An architect is expected to be able to calculate. From a mathematician—warning! Contrapositive!—I expect that he can engage with aesthetics/beauty, with measure/number/proportion (the golden ratio! + the Fibonacci sequence!), beyond the abstract beauty of mathematical proof, which has already gained some fame in academic circles:

"Mathematical beauty is found mainly on three levels, which are very closely connected:

First, at the level of surprise. The most fascinating proofs are always those that one only understands in the last sentence and then immediately grasps fully.

The second level is that of elegance and clarity of a mathematical result. The clarity is relieving and creates the feeling of mastering the matter. Often, the degree of elegance and clarity can be surprising.

The third level is that of structure. Recognizing connections between objects is the driving force of all science, and in no science have structures been shown as clearly and rigorously as in mathematics. It is this level that points to the harmonious cosmos and the transcendent.

A fourth level, which is not scientifically definable, is that of mystical beauty. Followers of Kabbalah or numerology attribute extended meanings to mathematical objects, especially the 7 natural numbers, whose parallel interplay on mathematical and extended levels possesses a fascinating structure and therefore, again, a certain beauty."

Explain the aesthetics of the house design, the consistent inner logic of the floor plans, and the delicate proportional relationships of the facade using the means of your science, and seek a clear answer to the fundamental question: Is this a beautiful house?

@Polle-1967: At the beginning, we were also with the idea of a plot with a slope. But the problem is usually that the slope is mostly counterproductive. In addition, searching for a plot itself is difficult enough—size, building envelope, location, orientation. On top of that, we fail to meet about 90% of the development plans. Then the issue of groundwater is not to be underestimated. If you are looking in a manageable market (Cologne metropolitan area), a sloped location moves far back. The current plot would be very favourable for the planning; we would hardly have to excavate. We will probably have to bring in soil to fill.

Ground floor at street level means you drop 2.80 meters into the basement. The idea is that if you stand at street level zero, from there half a story down and half a story up. The basement will be a full story, with the upper floor we will be careful that it does not become a full story.
( Ground area upper floor: 7.26 x 13.0 + 2.0 x 0.49 + 4.74 x 13.0 = 156.99 sqm
ALLOWED: 156.99 sqm x 0.75 = 117.74 sqm
SECTION AT 2.30 M LINE: 117.10 sqm (DETERMINED WITH CAD)
117.10 < 117.74 )

: But that is a vicious circle. You would only be undisturbed in the basement if the parents-in-law lock themselves in their apartment. The idea is the same, a corridor with 3 doors as a distributor. You could certainly redesign the upper floor so that both children's rooms are arranged in such a way that they do not affect the granny flat under each other. Or design the upper floor so that there is no longer a common distributor. However, the “problem” is only shifted. In the shared staircase there remains an intersection unequal to the empty set. So if our daughter walks naked through the staircase at night because we did without a children's bathroom, she could meet our tenant in the staircase.

: A really interesting presentation, I like it a lot (I mean that honestly). But asked differently, what does it bring me in practice? If I were to say now that the windows on the ground floor guest WC, bathroom, and office are at the same distance/ratio as the Earth to the Moon and Sun, 50% of readers here would say aha, I didn’t notice that at all and 50% would say great, that way you don’t have more light in the house at night either. The question, is this a nice house, I cannot answer like that, for that I lack the definition of “nice”. But I can say very precisely what I like, what I don’t like, and what is “whatever” to me. We approached the topic differently and planned our ideas as far as floors, among other things in Excel. Had the staircase in the middle, slightly set forward, then tried to bring light in upstairs. Otherwise, rectangular house, gable roof, plain. Partly because of costs, partly because the neighbouring buildings are also quite plain. Compared to that, we like the current design very much. The idea with the shared distributor on the left (saves unnecessary corridors) or the entrance area created on the ground floor, where you gain a covered area without later having to worry about how to properly get a roof on the house wall without having to stand in the rain or the mailboxes constantly getting wet. My wife has already mentally painted or clad the extension to the east. No idea if we’ll still add something to the exterior appearance.

... "I love it when a plan comes together"... :cool: The building application will be submitted before Christmas, the notary contract for the property was signed today. Now it's time to wait for the authorities. If everything works out, the groundbreaking is planned for March. ;)

Here is a small update and the current plans as requested. The land registry transfer was last week, so we are now officially the owners. Unfortunately, the building permit is not yet available; we are waiting for it daily so that progress can finally continue.

Attached are also the current planning figures:

    [*]Calculation of living and usable areas according to DIN 283 and II.BVO: total usable area: 55 sqm, total living area: 322 sqm
    [*]Gross volume: 1,500 cbm residential house, 165 cbm garage

The plans and images are mostly schematic or indicative:

    [*]Bathrooms and utility shafts will still be properly planned
    [*]The law requires that the access on the ground floor have a maximum slope of 6% gradient/decline. The path will therefore either be integrated into the front garden or we will plan a stairlift/lift platform at the stairs. So there will be no huge ramp there
    [*]In the basement, there will be a large terrace facing south, about 4 x 10 meters, partly covered by our balcony on the east side. Furthermore, of course, access to the garden. Since parents-in-law (family) will be moving in here, the basement (laundry room) will be used jointly. Furthermore, of course, there will be no rigid separation between garden/terrace. But still, a clear boundary was important to us.
    [*]We on the ground floor will plan a proper garden access via our west balcony, no spiral staircase. Preferably at ground level. We have about 800 sqm of virgin land in the south/west for planning and use. There are no detailed plans yet here; we still need input or probably a garden architect. Planned, of course, are a terrace, barbecue area, play area, and garden (low maintenance)
    [*]The granny flat in the attic will definitely be rented out to outsiders. We don’t yet know exactly how. Through friends, we know, among other things, that many Bundeswehr personnel currently moving to the Cologne-Bonn area look for a granny flat during the week. Here, however, we have provided a clear separation: washing machine in the bathroom, balcony available, no cellar use planned. Whether we offer the garden as well will certainly depend on the sympathy and tenant.

The plot suits our project very well. Due to a slight east-west slope, we only have to remove about 1.50 meters of earth in the east (garage) and then probably fill in on the west so that we can get from the ground floor reasonably into the garden here. There are neighbors to the east and north. Otherwise, a quiet cul-de-sac, turning circle, and edge of town location. To the west, a country road adjoins a dike and to the south an unobstructed view over fields.

Attached are the site plan, north view with terrain profile, and the floor plans for basement, ground floor, and upper floor:
