I’m venturing into this part of the forum to share our floor plan for discussion. I’m hoping for constructive feedback and ideas in case improvements would be advisable.

We want a bright house of about 160-170 sqm (1700-1830 sq ft). We would prefer an open staircase design, but it should not interfere with the floor plan. The flat roof dormer is more than just a nice-to-have... 🙂

Overall, we like the current floor plan very much, but since we are building novices, we would like to go over it with you experts to identify any possible issues. As we haven’t signed the contract with the general contractor yet, there are unfortunately no detailed dimensions available. The furnishing in the kitchen, bathroom, and living area is not yet fixed, so please don’t focus too much on those!

Orientation: the street and entrance are on the north side, terrace faces southwest.

Development plan / restrictions
Plot size: 854 sqm (9190 sq ft)
Slope: no
Site coverage ratio: 0.4

Style, roof type, building type: modern gable roof house (without eaves)
Basement, floors: no basement; 1.5 or 2 storeys; cold roof
Number of people, ages: 4 people (42, 41, 8, 5)
Room requirements on ground floor: kitchen, living, office, shower/WC, utility room; upper floor: sleeping, dressing room, 2 children’s rooms, bathroom, reading corner
Office: used for family or home office? 1 home office
Number of overnight guests per year: max 2

Garage, carport: garage or carport (6x9 m (20x30 ft) – position and storage room next to or behind garage not fixed yet – orientation on plot either lengthwise or widthwise)
Utility garden, greenhouse: no
Further wishes / special features / daily routine, also reasons for decisions:
  • Seating window on upper floor (bay window) – to hopefully bring plenty of light into the hallway and provide a nice view
  • Open staircase (straight or with landing, no preference)
  • Kitchen without direct line of sight from living area
  • Office preferably with garden access

House design
Origin of the design: original floor plan from Gussek House “Zypressenallee,” adapted to our needs and wishes by a general contractor’s planner

What do you like most and why? We like the layout and orientation of the ground floor, with sightlines from the entrance area

What do you like least and why? Uncertainty whether the kitchen is too tight; arrangement options for living room (sofa, piano!, bioethanol fireplace?) – possibly remove the middle square window in the living area on the ground floor in favor of more space for furniture?

Price estimate from architect/planner: 600,000 EUR (including garage, additional construction costs)
Personal price limit for house including equipment: 600,000 EUR
Preferred heating system: air-to-water heat pump

If you have to give up on certain details or extras:
- Can give up: staircase, 10 sqm (110 sq ft) of living space
- Cannot give up: bay window on upper floor (I just really like this nesting box)

Why is the design as it is now? For example:
The desire for a bay window with reading window and open architecture was implemented, combining examples from various magazines...

The bay window above then practically floats in midair, even though underneath it could almost be a lifesaver, which is almost laughable. But I guess that was just a fanciful idea, right?

Yes, I think that was a little crush on a show home somewhere: that a reading bay juts out like an extended drawer. Straight, single-flight staircases are another detail that, as a central favorite, has to survive any downsizing ;-)

Who here has a preference for a built-in freezer door in the kitchen?

Floor plan of a single-family house with garage, car, living/dining area, kitchen, office, utility room.


May I just point out that your drawn sofa is only 2 meters (6.6 feet) wide. That’s not enough to comfortably seat four people. Also, the patio door wouldn’t open if the sofa was 2.70 meters (8.9 feet) wide.
As a side note: a practical staircase would be about 3.80 to 3.90 meters (12.5 to 12.8 feet) long. Yours is currently 3.70 meters (12.1 feet) with 14 steps.

Your dining table is indeed 2.40 meters (7.9 feet) long but only 80 centimeters (31 inches) deep. Since it’s in the main traffic route and central hub, you end up blocking each other.

The house is 8 meters (26.2 feet) wide externally, so about 7 meters (23 feet) internally. If you want to fit both a straight staircase and a dining area side-by-side, logically it just doesn’t work. No matter how we spin it, the layout or the position/type of staircase needs to change.
Now it’s up to you: what will you decide? What has to stay, and what can be removed?

Oh, I didn’t even notice the staircase. That could be a deal-breaker. Ouch!

The dining area feels quite tight. The living room door even opens into the hallway on purpose.

Actually, the living room door is not planned to be installed at first. However, if separating the living room from the hallway becomes desirable in the future, it should at least be feasible as an option.

@RomeoZwo: We might plan the garage as you suggested. That’s a very good point, and we were still uncertain about that ourselves.

Yes, that reading nook was definitely a desired feature. Regarding the staircase, we didn’t specify anything to the architect after our last discussion. Overall, we gave him very few requirements.

Which of you is really attached to the tech cabinet door in the kitchen?
Actually, no one is. As long as you can get in somewhere. 🙂

If you want to have a straight staircase and a dining area running parallel, it just doesn’t logically work. We can turn and twist this all we want: it requires a different layout and/or a different staircase position.
So now it’s up to you: what do you decide? What has to stay, and what can go?
The decision would probably fall on the option that causes the least disruption to the changes. We’re not really fixed on anything. A different staircase would actually require a completely new plan. After all the time and cost calculations, that would of course hurt the most…
