Hello dear building community!
We are several months further along in the planning process, financing is secured, and the development of our zoning area is almost complete. We hope to start construction by the end of the year. We are currently finalizing details with our general contractor and are especially interested in your opinions and experiences regarding our window layout. We are not yet completely satisfied with the exterior views. The windows have not been ordered and can still be changed.

Here are the key details again:

- Garages and carports only allowed within the building envelope or within designated areas for garages and parking
- Driveway width from the street may be max. 4 m (13.1 ft)

Homeowner Requirements
Style, roof type, building type: Bauhaus, flat roof, solid construction, full floors, half-turned wooden staircase
No basement, 2 floors
Number and age of occupants: 3 people; 30 years, 30 years, 12 months
Space requirements on ground floor: open living-dining area, office, utility room, pantry, shower-toilet
Upper floor: master bedroom + walk-in closet, 2 children’s bedrooms, bathroom with tub, shower, and double sinks
Office use: family use or home office? Home office / guest room
Number of overnight guests per year: 10-20
Open or closed architecture: open
Conservative or modern design: modern
Open kitchen, cooking island: yes, possibly island or U-shape
Number of dining seats: 6
Fireplace: no
Music/sound system wall: no
Balcony, roof terrace: no
Garage, carport: probably carport
Utility garden, greenhouse: possibly
Other wishes / special features / daily routine, including reasons for choices or exclusions
House design
Planner:
- Planner from a construction company
- Based on a floor plan of a pitched roof house with a high knee wall from a southern German eco prefabricated wood construction company
Favorite features, and why? Efficiently planned spaces (hopefully 😉 ), window seats, cozy zoned living-dining area opening to the garden at the back, walk-in shower, washing machine located on the upper floor; open ground floor, discreet upper floor
Dislikes and reasons: exterior views on west and south are still unusual and need getting used to
Cost estimate by architect/planner: 320,000 €
Personal budget for the house, including fittings: -
Preferred heating system: air-to-water heat pump
What could you do without?
- Could dispense with: KfW 55 standard, T-shaped layout in the bathroom, kitchen island; with good arguments: possibly rotate the straight staircase 180 degrees and access it from the hallway
- Cannot do without: in our opinion, the design does not reflect excessive demands
Why did the design turn out this way? For example:
What do you consider especially good or bad about it? The garden is very important to us. In our opinion, the rectangular floor plan suits the plot better than a square one to maximize use of the land (sun on the west terrace). We are three people, and I primarily work from home, my wife occasionally. That’s why having 4+1 small rooms was important to us.
What is the most important/basic question about the floor plan summarized in 130 characters?
The open and cozy ground floor connects well to our garden and terrace, while the upper floor offers enough privacy inside and protection from outside views. We searched a long time for the optimal plot and want to use it as a retreat with a future swimming pond/pool and a small utility garden.

We are building 135 square meters (1450 square feet). The fixed price is confirmed. Maybe now it becomes clear why I can no longer do a redesign. It simply gets too expensive because everything would have to be recalculated based on the daily current prices.
(...)Don’t let that unsettle you. If everyone built to what is considered "basic standard" here, only the top 10% would live in their own houses, while the rest would be stuck in prefabricated blocks or underground shelters.

There is still potential to make something out of it.

My windows, however, are much larger to make it look right. The appearance of your house is more like a cheap flat-roof design from the 1960s. But you can see from Dietmar’s suggestion that with some façade design and changes to the windows, you can already achieve a lot—without significantly increasing the window areas.
