ᐅ Single-family Home on a Hillside – Many Planning Considerations

Hello dear forum members,

We are still quite at the beginning.
We (26 and 27 years old) are still very early in the process – we have already visited a planning office a few times, but we are not really making progress! I hope you can help us. We look forward to criticism, ideas, and suggestions for improvement.
Here are the key details:
The plot is on a slope and can be accessed from both sides (east and west). If I have made any major mistakes, I apologize in advance. I have provided the data as accurately as possible.

Development plan/restrictions
Plot size: approx. 900m² (9688ft²)
Slope: Yes! – approx. 28%

Orientation: Front door facing east
No maximum height or other restrictions

Owners’ requirements
Roof style: shed roof, low-pitched gable roof, hipped roof would also be nice (but probably too expensive)
Number of floors: max. 2 (“multi-purpose basement”)
Number of occupants, age: 2 (26, 27)
Space needed on ground floor and upper floor: max. 145m² (1560ft²)
Office: family use
No open-plan kitchen – living room somewhat separated

Number of dining seats: 6 – corner bench seating

WC/bathroom – small on ground floor or basement as well

Balcony, small!
Garage or carport – either a double garage or single garage plus carport; garage must be on the left
Other wishes/special features/daily routine: large hobby room (20m² (215ft²)), 2 children’s rooms, WC with window (if possible), separate bathroom, few windows on the street side (east) – also bedroom on that side (because it is cooler there), fairly short distance from garage to kitchen

House design
Planning by: planning office
What do you like most? – sheltered terrace, elongated/narrow shape, two stories
What do you dislike? – “boxyness”
Cost estimate according to architect/planner: 300,000–350,000
Preferred heating technology: wood heating / pellets

If you had to give up something, what details/additions could you forego?
- can give up: large rooms (children’s rooms can be very small)
- cannot give up: separate WC/bathroom, garage, hobby room

My thoughts:
Basement:

• Does it really make sense to have the shower and toilet behind the utility room?
• Where is north? I assume it is by the entrance?

Ground floor:

• The hallway will be very dark
• There is a lot of wasted space between the dining area and kitchen
• The living room feels somewhat like a small room or chamber

I’m not completely convinced by the layout.

I am completely missing a site plan that shows the slope, orientation, as well as roads and access points.
At first glance, I would say the garage has a better location than the terrace 😉

Best regards

Thank you for the quick response!
I don’t have a site plan – does the planning office have one?
Why a “better location”?

Phew, I’m not really comfortable with this. It reminds me of a platform—long and narrow.
Why isn’t the attic considered a non-full floor?
There are many corners and, above all, hallways that are way too narrow. The path to the kitchen is like a maze. Don’t you have more space available in width?
Does your design firm build 18.50 meters (61 feet) wide?
Our architect once mentioned that she builds a maximum of 15 meters (49 feet), but I’m not sure where that figure comes from.
How many square meters (square feet) of living space are currently planned?

So, you should have the plot plan drawn on a sheet of paper where you can mark the rest with a pencil, right?

The location is not clear at all here!

Is the driveway in the garden, the street by the entrance, where is west?

Where is what here?
