Hello everyone,

since a plot of land is in prospect, we want to prepare for the future and ask you for advice, as we have almost no experience with development plans. We have already had an initial conversation with the Massa Haus consultant (the development plans were not yet available at that time), it is to be a KfW55 single-family house (gable or hip roof).

The plot is located on a north-facing slope, which raises some questions for us. I have already done some research on the internet and as far as I know, we generally have 2 options:

1. Level the plot completely/partially and support adjacent elevations -> high costs
2. Basement entrance, garden on the ground floor

Development plan/restrictions
Plot size: 525 sqm (17.5x30)
Slope: Yes
Floor area ratio: 0.3
Floor space index: see screenshots
Building window, building line and boundary: see screenshot, no information about boundary in text section
Edge development: Yes, if width allows
Number of parking spaces: 2 desired, in front of double garage
Number of floors: This is my question, see below
Roof shape: probably gable, since hip roof has only 22 degrees pitch at Massa Haus
Style: Modern single-family house
Orientation: free
Maximum heights/limitations: Max. ridge height 8 m
further requirements

The development plan states the building height limit H1 (plot no. 3882):




This is also outlined in the text section:



Now the general question arises whether the variant: garage/entrance in the basement, garden on the ground floor, sleeping on the upper floor is possible? The number of floors is not entirely clear to me, since it is clearly stated that the ground floor must be max 0.5 m lower or higher than the reference level 255.25, is that correct? If the house is built elevated, the ground floor is at least one story above the reference height 255.25.

Also, I do not read anything in the text section about the possibilities/permissions for leveling the plot. Is it theoretically possible, if several plots abut, that each builder can freely decide whether to level the plot or “raise” their house, i.e. build it on the garage or elevated?

How would you arrange or build the house on the plot?
Unfortunately, I cannot attach the text section as a PDF.

Attached is a sketch of the plot for better understanding:


Thank you in advance.

Regards

Simon

Timber frame companies tend to build towers

Do you want a garage?

Filling in what I believe is not allowed will cost you an estimated 80-100 k for support.
Maybe you can manage with 70 k
And what would you get from that?

Garage downstairs could cause you to miss a few centimeters of knee wall in the attic

Slope is expensive. The cheapest is to build with the slope and not larger than it must be.

What would be suitable for you
Garage or carport next to the house
1st level Entrance, sleeping possibly children's room, office, bathroom, building services, utility room
2nd level Living, dining, kitchen, guest WC
3rd level Attic what doesn’t fit downstairs or nothing

Take a look at Arifa. She has children's rooms downstairs and living upstairs

Since with a sloping plot you have to face some challenges anyway, a preliminary split-level design would be quite interesting for you. We built it like that ourselves, are quite satisfied with it, and would do it again.

We also have almost exactly 3m height difference over 30m (preliminary run also 40). If cleverly placed, you only have a half-level offset from the entrance to the garden level.

You can find our planning as guidance and

But I have to say one thing, if the general contractor has no references in split-level construction, I would only approach something like this with an architect. There are - especially in the field of technical building equipment (TGA) - quite a few things you have to consider.

Yes, a double garage was originally the dream; it would fit next to the house if you don’t have to keep a distance from the property boundary, otherwise it gets too tight with a 6m garage width and 10m house width.

I can’t find any "Arifa" in the forum :/. Either I’m too dumb to search or the name is wrong. I will also mention split-level in the next conversation, thanks for the tip.

I still find it hard to imagine sleeping in the basement or cellar :O... it would be best if I could see such a property in real life, I probably imagine it worse than it actually is.

Are you tied to Massa Haus?

For me, your UG is the EG.
That has nothing to do with a basement. The rooms are dry, of normal height and bright (as far as they are not underground).

We live on the EG because the garden is there and the sleeping rooms are upstairs.
I’ll send you some pictures later. You don’t notice anything about the slope in the living room.

Even if you don’t want to sleep there, plan rooms and a smaller floor area.

Here the plot rises from the north, where the street is, to the south, where the garden can be. So that here in the basement=ground floor there should rather be parents' bedroom, utility room, guest/office, etc. Then perhaps living, dining, cooking with garden access to the south and in an attic then children's rooms. For that, one could maybe keep the floor area smaller.
