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.

Slope: no
Site coverage ratio: 0.4

Client requirements
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...

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

The question is whether this would truly be THE solution, meaning sacrificing the one and only correct wish, or if it would simply reduce the problem a bit without fully solving it… I find it hard to imagine that with just a few centimeters. But then again, I don’t really know.

You’re here to borrow some knowledge, after all. A minute passes at different speeds whether you’re waiting for Santa Claus or standing outside a bathroom door—centimeters behave similarly. The “one and only correct wish” surely can’t be that the reading bay window creates a visible protrusion from the outside???

By “DIY,” they probably mean “self-contracting at some undefined point in the future.”

I’m afraid it is. Basically, nothing else matters; the bird’s nest up top in its shape and design is the must-have the owners want to indulge in.
I think that’s fine, as long as later on there’s no regret about the cramped dining table and the narrow bathroom door. The dimensions downstairs are just below the limit, and if the table stays there, it’s constantly in the way. The undersized sofa, limited by the patio door, is also only semi-comfortable. It’s tight everywhere, but not extremely so anywhere.

Exactly. In the worst case, you just rearrange the utility room and install the laundry chute, leave everything else as is, and end up with a house that is "more okay" than many others. You can then relax in your reading chair, enjoying the improvements since the thread started, and let things be—of course, only after consulting a qualified expert from the grounding system up to the last tile. For once, I am even willing to give my approval to the shoddy work pockets 🙂

Find a spot in the garden or elsewhere and mark out the dimensions of the entrance area of the future living room.

Then clarify with the architect the staircase regarding length and rise/run or tread depth. The finished ceiling height should be around 248 cm (8 ft 2 in) for you, right?
At the currently estimated staircase length of 370 cm (12 ft 2 in), the tread depth is just under 26 cm (10 in), which is basically sufficient but should be checked to see if it feels comfortable.

Many thanks in advance for your great tips!
Regarding the stairs, we have an appointment with the stair builder next week, because we want to take the trade out and contract it ourselves. They should be able to advise us, right? Maybe it’s even possible to test it in their showroom.
The rough ceiling height on the ground floor will be about 2.77 m (9 ft 1 in).

As for the dimensions of the dining table and sofa, I probably should have measured. My bad. I think I told the architect a dining table size of 200x100 cm (79x39 inches) and a sofa at least 2.90 m (9 ft 6 in) wide. Would that relax the dining area a bit? For the sofa we still need to find a solution.

No, it will possibly be commissioned separately later on 🙂 Just as described by @11ant.
Yes, the thing with the reading bay window… Initially the house was about 170 sqm (1830 sq ft), which made everything a bit more spacious. But like many others, we had to start somewhere to cut costs. Reducing floor area was effective in doing so. I freed myself from many requirements after the last draft, but I couldn’t hide this last wish from the architect anymore. 😎

I think I told the architect that the dining table should be 200x100 cm (79x39 inches) and the couch at least 2.90 m (9.5 ft) wide. Would that make the dining area a bit more comfortable? However, a solution is still needed for the couch.

If I understand correctly, you have 2.82 m (9.25 ft) of wall space for the couch, so it’s not much less than you mentioned. For me, that would be a bit tight for 4 people. Roughly speaking, for a dining table you usually plan for a depth of 90 to 100 cm (35 to 39 inches) and about 60 cm (24 inches) per person. Your dimensions of 200x100 cm (79x39 inches) are therefore reasonable. I would plan at least 80 cm (31 inches) of clearance for the stairs and glass door, maybe even a bit more, so you’d be around 360x260 cm (142x102 inches). Then the dining area should fit, right? 🙂

@Gregor_K We based the couch size on our current one. Yes, it’s not very large and the kids are still small... 😎

By the way, this is how the dining area/staircase looked before we planned the optional glass door. Should we maybe skip the glass door to save space?

The attached image is low quality because I quickly cropped it. At least the exterior dimensions are the same. If needed or wanted, I can try to provide a better quality version later.
