@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.
