Hello everyone,

Attached is our floor plan, on which the detailed construction plan will be based in the coming days. We would appreciate any constructive criticism and suggestions for improvement.

Development Plan / Restrictions
Plot size: approximately 850m² (9,150 sq ft)
Slope: yes, see terrain elevation image
Site coverage ratio: 0.3
Floor area ratio: 0.6
Edge development: yes
Number of parking spaces: 1.25
Number of floors: 2
Roof type: gable roof - visible roof truss
Roof pitch: 15-30 degrees
Architectural style: family house, country house
Orientation: north-south (planned)
Maximum cut on plot: 0.75m (2.5 ft)
Maximum fill on plot: 0.75m (2.5 ft)
Knee wall height:
Valley side: permitted up to 0.50m (20 inches) measured from top of raw ceiling to top of purlin;
Hill side: permitted up to 0.75m (30 inches), measured from top of raw ceiling to top of purlin.

Additional Specifications
Basement, floors: yes, 2
Number of occupants, ages: 4 (3, 6, 39, 41)
Space requirements on ground floor and upper floor:
Office: home office
Garage, carport: garage
Guest bedrooms: many
Open or closed architecture: open (living area)
Open kitchen, kitchen island: yes
Number of dining seats: 8 (one central dining table)
Fireplace: yes

House Design
Designer: self-designed
What do you particularly like? Living area
What do you not like? The slope is somehow not being utilized, but we can’t think of any ideas
Preferred heating technology: gas condensing boiler seems appropriate since gas is available, but not yet finalized

Other Notes:
  • Parcel 4 in the site plan is ours
  • The 2m (6.5 ft) line is not yet drawn, as the roof pitch has not been definitively determined
  • Windows etc., especially on the upper floor, are also not yet 100% fixed; we would appreciate any tips
  • North is at the top
  • We have a slight (?) slope (from 511.65m (1,681 ft) in the southeast to 507.86m (1,666 ft) in the northwest), but we don’t know how to use it positively… perhaps someone has a good idea so we can take advantage of it
  • The kitchen island is shown as 60cm (24 inches) in the plan, but will actually be 1.10m (43 inches) wide – hence the space between the chairs and the kitchen island

And initially, it was about the floor plan.

But that would become irrelevant.

Even if you are not very strict about the 75cm (30 inches), you can apply to remove more or less soil or add fill (or add another meter on the knee wall height). You end up building a forward-facing basement with a garage, allowing exit to the west, and in the center to the rear and southeast, so that the living level is then on the ground floor, which is not accessible from the outside at the front. The basement and ground floor would then be considered full stories, with the attic having 50 and 75cm (20 and 30 inches) knee walls.
This is a very simplified explanation, but building regulations can be interpreted favorably; however, that is hardly possible for a layperson.

Not far from here, removals of 1.50m (5 feet) were approved upon application.
I believe getting approval wouldn’t be a problem.

However, this requires argumentation by the architect—you as a layperson will likely receive a rejection.

You cannot simply place a single-family house on a complicated slope!

Aside from all the (completely justified) comments regarding the hillside location, here’s something about the kitchen planning:

If the refrigerator is going to stay as it is now, why does it have to go into that built-in niche? As far as I remember, it’s supposed to be a freestanding fridge anyway, which means it can be on display. I wouldn’t create a built-in niche and limit the external dimensions like that (besides the fact that niches tend to collect dirt that’s hard to reach and unpleasant). Either leave the corner open or move the fridge (then not freestanding but a built-in model) toward the back, integrated into the (extended) pantry.

I have nothing more to say about the current kitchen solution... I already did.

Garage:
Does it have to have a pitched roof? Are you planning to use the attic/storage space? If not, I would consider a flat roof. That way, you won’t have any restrictions for the upstairs windows.
Think about an eave at the front that shades the pantry window; otherwise, it will heat up in the evening (this is the west side, right?).

First, about the slope:
I don’t think this is a particularly complicated slope.

Grundstücksgrundriss mit grüner Umrandung, roter Diagonale und Parzellenangaben


In my opinion, the approach is quite straightforward:
Between the red diagonal line, the elevation is roughly the same (approximately 510.25 meters (1675 feet)).
We simply take measurements from point [1] accordingly and use these to fill up at point [2].
This creates a 25 by 25 meter (82 by 82 feet) area (shown in green in the image) on a relatively level height of about 510 meters (1673 feet).

In the far southeast, the terrain stays a bit higher, which is actually advantageous for privacy and similar concerns.

Looking at the driveway from the north side, there is only about 0.75 meters (2.5 feet) missing to reach approximately 510 meters (1673 feet) in the northeast,
and on the northwest side, from the outermost point, the height difference is 2.10 meters (6.9 feet) over 10 meters (33 feet) length or 1.60 meters (5.25 feet) over 7 meters (23 feet) length.

That shouldn’t normally cause any problems, right?
As a non-expert, I would suggest making the driveway gently sloped (around 50 cm (20 inches) incline) leading into the garage.
For the rest of the elevation change, I would use an external staircase to reach the 510 meter (1673 feet) level and thereby access the entrance area.

Oh, and the basement is planned as well...

Uh... you need to position the garage on the left side of the plan, right?


Your green area starts about 8 - 9 m (26 - 30 feet) away from the street.

Also, if you set the green area at around 510 m (1673 feet) elevation, then you are missing about 220 cm (7 feet) of height in the top left, northwest corner. A garage at ground floor level would have to overcome this height difference relative to the street, not just 75 cm (2.5 feet).

Above all, that would mean moving a large amount of earth and making the surface stable and suitable for building again.

Your planner should clearly illustrate this for you.

This somehow suggests parking with a car lift.

50cm (20 inches) is a length measurement. What do you mean by how many percent slope?
