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.).

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.

Our wishes were the following: [...]

Bravo! That’s what I call a perfect own goal: apart from @Würfel*’s slight improvement of the attic, there is only one design in this framework that meets the specification catalog (or, as mathematicians would say, the number of possible solutions is "1"). This design can only be improved if the planner is granted exemption from at least one of the conditions. You could also say it’s “locked in” :-(

This highlights a crucial difference between an architect and an “architect” (aka draftsman): a draftsman—if engaged and wanting to prove their skills—at best shines by exemplary adherence to the instructions given; a true architect would have pointed out to the client that they have crossed the line between being a source of inspiration and the gravedigger of the design, and that the architect needs more freedom to fulfill their task. Every mathematician learns this long before university: increasing the number of conditions decreases the number of possible solutions. Unfortunately, clients tend to be too emotional and too biased to let reason take the lead. At this point, an architect is a service provider who “only” knows how to design and ends up with no stake in the outcome, lending this ability to the client. The draftsman, like a loyal sled dog, will pull the cart into the mud if that course of action is ordered.

The staircase, which is only 3 meters long (10 feet), has nothing to do with taste…
I completely agree with you, you should add at least one step, better two. Although I don't find steeper dimensions as problematic for straight staircases as I do for the two spiral ones.

With a straight staircase, however, if you fall, it will be along the entire length—even if it’s shorter… Usually the reason for falling is the inconvenience. A double-winder staircase will stop you after about a meter (3 feet).
