House construction in South Hand Feasibility assessment of an amateur plan

Hello everyone,

after extensive research and countless discarded drafts, I have reached a stage with which I am very satisfied. However, I am a complete layperson and would like to get further opinions.

Before I go into my situation in more detail, here is the questionnaire:

Development plan/restrictions
Plot size: 732 m²
Slope: slight south-facing slope, approx. 2.5m gradient over 30m length
Site occupancy index: No development plan
Floor area ratio: No development plan
Building window, building line and boundary: Normal 3m boundary construction
Edge development: Normal 3m boundary construction
Number of parking spaces: 3
Number of floors: 2
Roof shape: Shed roof
Style: Modern
Orientation: South
Maximum height/limits: No fixed specifications
Further requirements: "As in the surroundings"; everything is built randomly there, so presumably everything is allowed

[U]Requirements of the builders[/U]
Style, roof shape, type of building: Modern, shed roof, low-energy house
Basement, floors: No basement, 2 floors
Number of persons, age: 4 persons, ages: 30, 29, 2, 1
Space requirements on ground floor, upper floor: Upper floor guest bathroom, kitchen, living room; ground floor bedrooms, bathroom, utility room
Office: family use or home office?: Home office must be possible for one person
Overnight guests per year: Estimated occasionally 2, very rarely in advance sometimes up to 4
Open or closed architecture: open to the south, closed to the north
Conservative or modern construction: modern
Open kitchen, cooking island: yes, preferably, but not mandatory
Number of dining places: 4, extendable to 8
Fireplace: no
Music/stereo wall: yes
Balcony, roof terrace: yes; roof terrace
Garage, carport: no, but a carport may be retrofitted one day.
Kitchen garden, greenhouse: no
Other wishes/special features/daily routine, also reasons why this or that should or should not be:
- Electrical star wiring and KNX bus system
- House leveled to the highest plot height to have the roof terrace as high as possible
- Sports room integrated with office, with space for a multifunctional squat rack
- Driveway top left (north-west)
- Connections (sewer, etc.) bottom left (south-west)
- Visibly wider interior walls are intended as load-bearing walls (24cm thick)

[U]House design[/U]
Planned by whom: self-designed
What do you particularly like? Why?
- Window front with view over the town, living room upstairs
What do you not like? Why?
- "Angular" rooms: a children's room, utility room and office
- Guest bed squeezed into a niche
Price estimate according to architect/designer: None yet
Personal price limit for the house, including equipment: 400,000 (incl. additional construction costs)
Preferred heating technology:
- Air-to-water heat pump with heat recovery, ventilation system
- Underfloor heating
- Photovoltaics

[U]If you had to do without,[/U] which details/extensions
- could you do without: walk-in closet, "bar" at the kitchen, photovoltaics (but still pre-install necessary wiring)
- could you not do without: bus system, sun terrace

[U]Why has the design turned out as it is now? [/U]E.g.
Standard design by the planner?
- No, the goal was to use the plot as optimally as possible so that there is still enough garden area where the children can play, the view can be enjoyed, and a lot of sun shines into the living space.
What do you think is particularly good or bad about it?
- good: especially good use of space and above all the area where the most sun shines
- bad: angular shape on the ground floor
- protruding area in the utility room so that the outdoor installation for the air pump can be placed there

[U]What is the most important/basic question about the floor plan summarized in 130 characters?[/U]
Am I overlooking something important that would make this floor plan impractical without high extra costs, or does the rough plan look plausible so far?

Do you have such a great view?

I am an advocate of direct garden access from the living rooms.

The budget does not fit. It is too small.

Disproportion between children's room and hallway
Hallway bigger than children's room

I would not place the utility room there.

The ground floor looks like Tetris. Remove a few corners.

Hi

Why not reverse the shed roof in the upper floor and open the living spaces to the garden side with significantly less roof pitch?
The ground floor layout is no good; I would start from scratch there.

Architecture serves the people who live in it and you have small children. Supervising them becomes a very thankless task when it comes to the paths between living space, children's rooms, and "outside" as well as the arrangement that allows the children to leave the house without passing through the living space. Since the house was not designed for an Au-Pair or child supervision, I consider the design unsuitable for a family with children under 16 years old. Basically, the idea of living "upstairs" and sleeping "downstairs" is appealing - especially if the view is worth it. The budget does not seem to fit the design; with it, you will probably only get about 2/3 of the way.

- Staircase too short, it's only about 3m
- Coming in and no space for a wardrobe... or is the entrance supposed to be on the sleeping floor? How is the alignment with the slope then?
- Master bedroom 3 m for the bed (a 160 cm bed fits reasonably max, and then on the right and left there are only 60/65 cm (bed frame)
- Kitchen design... distance between island/tall cabinets is not practical

Hi again Here are some views of our last house for inspiration. The windows are just over 3 meters high. The room height is about 3.40m.
