Hello everyone, after picking up many valuable tips here as a silent reader, I would now like to present our floor plan for discussion (Note: there are still a few errors in the plan because the planner sent the draft quickly; these will of course be corrected, e.g., the 2-meter (6.6 ft) line on the upper floor right side, escape routes, etc.).

Development Plan / Restrictions
Plot size: 807 sqm (8688 sqft)

Other requirements: utility line along the western property boundary with a 4 m (13 ft) protection zone

Requirements of the Homeowners
Style, roof type, building type: classic single-family house with a gable roof
Basement, stories: no basement, 1 full story
Number of occupants, ages: 3 (33, 33, 2), a 4th is possible
Room requirements on ground floor (GF), upper floor (UF): GF: open living/dining area, guest room, shower/WC; UF: 2 children’s rooms, bedroom, dressing/storage, bathroom

Garage, carport: double carport
Utility garden, greenhouse: no
Other: moderately busy circular road to the south (50 km/h (31 mph)), no direct view due to raised earth embankment (additionally noise protection wall planned if needed), view of greenery from living room

Wishes / special features / daily routine, including reasons why or why not: desire for storage option in the kitchen for glass recycling, paper, water crates; guest room must be on the ground floor to ensure necessary privacy

House Design
Planner: planner from a construction company, based on our specifications

What do you particularly like? Why?: living area because of the kitchen island, storage under the stairs, recessed living area with garden view (no traffic area), large dressing/storage on the upper floor, bathroom not visible due to double casement window, utility/mudroom, distance from stairs to main entrance—> we really like the ground floor except for the small utility room; we are uncertain whether the children’s rooms on the upper floor are comfortable and easy to furnish

What do you dislike? Why?: utility room very small, children’s rooms are very awkwardly shaped, bedroom very large compared to kids’ rooms (12-14 sqm (130-150 sqft) would have been enough for us), location of the outdoor unit for the air-to-water heat pump
Price estimate according to architect/planner: €315,000 without kitchen, floors, painting, landscaping, and additional construction costs
Personal price limit for the house, including equipment: €420,000
Preferred heating technology: air-to-water heat pump

If you had to give up, which details or additions
-you could give up: straight staircase, but not storage underneath
-you could not give up: storage on the ground floor, guest room on the ground floor with nearby shower/WC

Why did the design end up as it is now?
Which of your wishes were implemented by the planner: living area, storage under the stairs accessible from the kitchen; wishes stemmed from a mix of many examples from various magazines

What makes it particularly good or bad in your opinion? Tailored individually to our wishes (especially on the ground floor)

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

Are there suggestions for a better divided upper floor, possibly with a different staircase? It is important to us that the children’s rooms remain on the south side. Or do you think concerns about the awkward children’s rooms are not justified?

Plot plan with building, terrace and building boundary, dimensions and areas.


Floor plan of living and work areas: kitchen, living/dining area, office, hallway, stairs.


Upper floor plan: bedroom, two children’s rooms, bathroom, dressing area, stairs.

Do I understand correctly that the main bathroom has no window? This would be the first plan with a windowless main bathroom.

Is the thick grey area in the bathroom the wall plus drywall? The fixtures can also be installed inside the wall without drywall (see photos; the wall is 17.5 cm (7 inches) Poroton block). In the main bathroom, the bathtub plumbing is integrated into the exterior wall.

Construction site: exposed pipes, cable bundles on the floor, brick walls.

The main bathroom will have at least one double casement window, possibly two. Since it involves installation in the exterior wall, I will discuss it with our planner. Thank you!

@driver55 could you perhaps elaborate on that? I am especially interested regarding the upper floor.

Then the bathroom will need to be redesigned. The "thick gray" mainly fills the sloped ceiling area until it is high enough for the toilet. The toilet can hardly stand freely in the room...

Good point. However, the bathroom layout is not final yet. We are considering placing the toilet opposite the washbasins.

What I notice about the upper floor: The walk-in closet is very long and narrow. This might be okay for a closet, but it’s a matter of preference.

What I definitely wouldn’t build like this is the second child’s bedroom. You only have a raw internal dimension of 1.93m (6 feet 4 inches) in that niche. Apart from fitting a crib, you can hardly use the room in that corner. You won’t fit a standard double bed, not even a futon. After all, children grow up too. 😉

It’s not just the children's rooms that suffer from the stairwell exit, but the entire house is affected by the straight single-flight staircase. I wouldn’t necessarily place the children’s rooms on the south side either: full shading due to strong direct sunlight during homework time doesn’t seem like a quality-of-life improvement for the kids. A vestibule with a clean-off area would probably provide more benefit than this pointless side entrance, whose door is already obstructed in the plan and is overall as cramped as a glove compartment. The small walk-in closet will become quite cluttered, despite the overall lack of storage space. Overall, the design is a perfect example of how to plan tight spaces—or at least the impression of tightness—everywhere. For example, the Town & Country range offers several examples of how to design houses in such an economy format more functionally. I also don’t see any reason, given the lot and building envelope, to choose such a nearly square floor plan. By the way, the site plan could use a less tight cropping. From the 45cm (18 inches) thick walls and window recesses, I assume the wall structure includes a brick cladding (which could likely be omitted to save budget). Am I correct in assuming that, similar to @Richooo in https://www.hausbau-forum.de/threads/grundriss-nach-erstem-planungsgespraech-140m2-1-5-geschossig.42222/, an Eco System "Variohaus" (which model?) is planned?
