Development Plan / Restrictions
Plot size: 327 m² (3,526 ft²)
Slope: no
Site coverage ratio: 0.2
Floor area ratio: 0.3
Building window, building line, and building boundary
§34 - 3 m (10 feet) setback, etc.
Edge development: Not relevant to the question
Number of parking spaces: 1
Number of floors: 2
Roof type: Gable
Architectural style: Modern
Orientation
Maximum heights/limits
Other requirements
The house itself is determined by the developer and therefore cannot be influenced in terms of dimensions, shape, and orientation (see floor plans). The focus is solely on the internal floor plans, layout, and optimal use of space.

Homeowners’ Requirements
Style, roof type, building type: Set by developer, as above
Basement, floors
No basement, 2 floors with converted attic
Number of occupants, age
Current: 2 adults, one child (8 years), two more children planned
Space requirements on ground floor and upper floor
Square meters predetermined by the building (52.44 m² (565 ft²) gross internal floor area)
Office: Home office?
Overnight guests per year: 8
Open or closed architecture: open
Conservative or modern construction: modern
Open kitchen: Yes, island only if not too cramped
Number of dining places: 6
Fireplace: no
Music/stereo wall: home cinema
Balcony, roof terrace: no
Garage, carport: no
Utility garden, greenhouse: later, not part of the question
Additional wishes / special features / daily routine:
We still need some storage space somewhere, as there is no basement.
Extra shower bathroom, because with 5 people in the morning it would otherwise get too congested, and also for guests.
Partner dislikes “slanted” room doors, so rooms should always be accessible at right angles (entry to kitchen/living room is an exception (but no door installed there either)).

House Design
Planner:
- Do-it-yourself based on a plan from the builder
What do you particularly like? Why?
6 rooms included, extra shower bathroom included, managed to get some storage space.
What do you dislike? Why?
Narrow bedroom, very small utility room (must be at least 5 m² (54 ft²) according to the builder), one room with many corners in the attic.
Price estimate according to architect/planner:
300,000
Personal price limit for the house, including fittings:
330,000 (all in, excluding exterior works and additional costs)

Preferred heating technology:
Air source heat pump

If you had to give up, on which details/extensions
- could you give up:
Storage room (then maybe as a shed?)
- cannot give up:
Second shower bathroom, separate office

Why is the design the way it is? For example
Standard design by planner?
Which wishes were implemented by the architect?
A mix of many examples from various magazines...
What makes it particularly good or bad in your opinion?

Self-modified design proposal from the builder. Originally had only 4 rooms.

What is the most important/basic question about the floor plan in 130 characters?

Is this floor plan even possible?
Have we forgotten something? Can it be made nicer somehow? According to the builder, the staircase can be smaller, but the space must probably be allocated to the utility room (which the builder says is too small).
We are particularly concerned about the lack of storage space (no basement, no attic).
Where do you store your stuff then (not bulky waste, but items you do not need all year round: inflatable boat and air mattress, Christmas tree, winter jackets, etc.)?

Location plan will follow.

Thanks and regards

A 2m (6.6 ft) double bed won’t fit in my room. And it was within my budget (well, sort of...). And before the argument comes... if there was a partner, they would still have to fit at the kitchen table, in the bed, and on the sofa... and by calculation, that would still be 25m² (270 ft²) per person...
With such a small bed, you must really love him!

And as someone who is absolutely against basements, I'll bring this up again.
Try designing a ground floor without that tiny utility room, where a six-pack of beer no longer fits, and plan upstairs with one less room.
A home office can still be placed downstairs if there are three children, or the oldest might want peace and quiet and be fine with a light well.
Tools, an inflatable boat, decorations, clothes, etc. can be stored there.
Laundry, pantry, storage room.


Oh, the builder rejected the basement and pointed to the larger (and more expensive) neighboring lot next door. As if I could afford a basement then...

Is the building envelope fully utilized with 10 x 6.5 meters (33 x 21 feet) for one half?

With a floor area ratio of 0.2 and 327 m² (3520 ft²), the maximum depth = 10.0 m (33 ft) results in exactly 6.53 m (21.4 ft). So, 6.50 m (21.3 ft) building structure plus a 3 cm (1.2 inch) clearance. The question is whether the building envelope actually allows for this maximum dimension.

Probability of twins: 1.2%. So I wouldn’t take that into account when planning a house.

Tell that to my coworker, who was building a house for two to three children. With the first birth, twins arrived. Undeterred – because it was so wonderful – they went for the second birth, result: twins again. No, not test-tube babies. Since he owns dozens of hectares of land around his homestead, expanding wasn’t a problem; he simply added an extension.

Yes, let it be 0.2 * something low. What remains has already been "reserved" by the building permit for the terrace.

I just found out that he actually owns another property nearby. It's just a larger street but it’s something to look into. This remains exciting.
