Floor plan design of a single-family house with a 10% south slope. House entrance platform stairs

Hello everyone,

Some time ago I already created a post about the arrangement and optimal use of our approx. 600 sqm plot with about 10% south slope.
We have now spent quite some time drawing, thinking, erasing, etc., and have now created the following floor plan.
Since we have about a 10% slope, I want to use the hill optimally. My idea is that the house entrance is in the landing staircase, i.e. on the level between the ground floor and the 1st floor, but with an enlarged landing.
Then half a level up to the upper floor (sleeping) or half a level down to the ground floor (living).
The idea came from the split level method.

Bebauungsplan/Einschränkungen
Size of the plot: 600 sqm
Slope: 10% south slope
Floor area ratio 0.3
Floor space index 0.6
Number of parking spaces still open, probably 2
Number of floors currently 2 VG planned
Roof shape: gable or hip roof
Style: classic
Orientation: north-south

Anforderungen der Bauherren
Style, roof shape, building type
Basement, floors
Number of persons, age: 2 adults, currently 1 child, future 2-3 children
Space requirements on ground floor, upper floor
Office: family use or home office? Office could be used as a third child’s room if needed
Overnight guests per year negligible
Open or closed architecture: open architecture
Conservative or modern construction: conservative
Open kitchen, kitchen island: U-shaped kitchen. We have already planned this in the kitchen studio. For us, 3x4m turned out to be optimal. We want a hidden door on the short side for passage to storage/pantry
Number of dining seats: 1
Fireplace: no
Guest WC should include a shower since my wife will be working shifts again in the future and thus a shower away from the bedrooms is convenient.

Hausentwurf
From whom is the planning:
- Planner from a construction company: ideas from a construction company but do it yourself

What do you particularly like? Why?
What do you not like? Why? We are unsure if the view looks cluttered on the north side at the house entrance on the intermediate level, because the windows for the upper floor start at the height where the front door ends.

Personal price limit for the house, including equipment: 500k
Preferred heating technology: heat pump

Wenn Ihr verzichten müsst, on which details/extensions
- can you do without: gladly fewer sqm.
- cannot do without: WC/shower on the ground floor.




The following rooms have been planned:
1: Living with sliding door to the dining area
2: Dining area
3: Kitchen with sliding door to the dining area
4: Utility room
5: Guest WC/shower
6: Hallway
7: Landing staircase with enlarged landing
8: Storage room
9: Bathroom
10: Child I
11: Child II
12: Parents’ room. Possibly with a partition wall so that you first go through a small dressing room into the bedroom
13: Hallway. The landing staircase is not drawn here.
14: Office / Child III

I look forward to your feedback!

Just a note, after that it’s not worth going into the floor plan any further. You are planning two floors on the hillside. 260 sqm GFA for 500k. With a bit of bad luck, the budget will only be enough for one floor. Certainly not both.

I find the floor plan a disaster. What is that supposed to be - a split-level apartment from the 70s? Does your house have windows too? And you don’t like the popular "open design" of the living area either?

Is there a reason why Room 5, the guest WC, awkwardly opens into the technical room (Room 4), so that the guest WC does not get a window and the technical room gets a lot of walking space instead of storage space? And where do you park the stroller, in other words, where is the wardrobe, the hallway that welcomes you, where you take off shoes and store jackets? Bathrooms are not stacked, that is not a problem, but a bathroom above the living room is not good. On the ground floor, it feels more like an apartment than a single-family house. 240 sqm costs around €520,000 in standard quality, excluding additional building costs and without splitlevel. Splitlevel does not cost a fortune, but there are additional costs.

Split Level is built when you want it to be open. Split Level lives from sightlines, open spatial structure, the rooms flow seamlessly into each other. What you have drawn there is not a Split Level, but the idea of a Split Level, just not implemented. You have simply planned two floors, a two-story building, and not even well.

240sqm costs in standard around 520,000€

You must have miscalculated there ;)
