Floor plan of a two-family house (side by side) on a south slope

Do you at least have pictures of the property where the slope can be seen? Or show the topography from the Geoportal. There are often contour lines there as well.

We are not planning this as a granny flat but as 2 residential units, also in ownership.

Here is the topography; the idea was to fill the excavation for the area in the ground at the terrace.

It’s not about looking out onto the terrace, but rather that when you enter the front door upstairs (sleeping level, private), you are directly guided to the living level downstairs.

Maybe a stupid question, but why don’t you have the living area immediately after the front door upstairs, with a free view from there down to the back? In front of that a nice raised terrace with a side staircase to the garden. My niece has something similar and I like it. Honestly, I’m just realizing now that you first have to bring everything through the house down the stairs, past bedrooms, etc.
also mentioned leaving the parental/other apartment mostly on one floor and you spread out more upstairs. I like that basic idea at first, what speaks against it? Ok, no ground-level exit to the garden, but instead a view from above, nice raised terrace...

Glass-walled terrace roofing is at least planned for the seniors, that would somewhat dampen the noise but yes, in the planning you are sitting close together, so maybe increase the offset there?

Such a construction is expensive and isn’t necessarily attractive either. The issue of privacy should be solvable through planning differently here without needing such structures.

We are also tending to plan quite a bit of fixed glass in the windows, and to refrain from some floor-to-ceiling windows. Also, window seats are generally on the chopping block. (We once said at the meeting that those would be kind of nice.)

That’s ok, it’s normal to consider various things first. I actually see more sensible investments than a window seat. We did look at it too but then realized that we would never read a book there as shown. You sit uncomfortably, at a 90-degree angle and next to a hot/cold pane. I prefer my beautiful, varied seating furniture for that. Large glass fronts for looking outside I find great though, and we implemented that rather generously so today I used my new window-cleaning robot for the first time.

We are not planning it as a granny flat but as 2 residential units, also in ownership.

Ok, but in the end living together isn’t really different, whether rented or own apartment. Still, there will be changes at some point, and that can just as well be with you. In that respect, a clear, also visual separation for both would be important to me.

Thank you very much. How large is the height difference of the contour lines? Presumably 2.5m?

Here is one with the construction site marked.



If you want to have a CP or garage in the west there, then the SSM has to go further south.

Is the garage allowed outside the construction site in the north?

The 3 m high SM cost a lot of money.

How did the neighbor in the west manage the slope?

Is there a reference point for the 9 m height?

Yes, the plan is from a house construction provider, they currently apparently have free capacity, so they already provided this draft without elevations and contract.

That sounds nice at first glance but is mainly useless on the second look - and completely so: without the elevations, they cannot even provide a roughly accurate price estimate. And planning - even if it is only the "planning" by a draftsman - without properly completed homework from performance phase 1 is grossly negligent. I would only let this general contractor participate in the candidate casting with a bag of minus points as a handicap.

The placement of the garages will be tricky, a double garage for the father-in-law is almost mandatory. I also smell a carport, I think. I placed the garage like this because, ideally, a driveway should remain free upwards on the garden property. It is currently outside the development plan and needs to be checked again.

That means the plot is only partially within the scope of the development plan, the color change on the plot indicates the boundary to the outside area? - then I would see only a corner of the garage as unpromising.

@11ant also mentioned leaving the parental/other apartment largely on one floor and you are expanding more upstairs.

No, not upstairs here, but downstairs - the seniors mostly only on the entrance level (which is the uphill side here).

The floor plan was made without exact heights, these are not available yet, currently requested.

Are you any further with the planning regarding the defined heights?
