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.

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?

By the way, dormer ... I was about to look at elevations, but there aren’t any in post 1 ... and I noticed that this dormer is planned as a projecting box on the upper floor.


Do you have one or two elevations for it ... I really have no idea what it looks like.
Here is an elevation for you showing what is meant by the nest box 🙂
I’ll take a closer look at your suggestions tomorrow. Need some sleep first. 😎

Ah, okay, thanks ... it's a matter of personal preference.

The windows on the upper floor caught my attention again. You are planning with a knee wall height of 200 cm (79 inches). That’s why the sill height is only 76 cm (30 inches), to allow for glass in the windows. The window recess itself will end at about 170 cm (67 inches) in height, then the roller shutter. The glass area, after subtracting the frame, will probably end at a maximum height of around 160 cm (63 inches), and likely have an overall height of about 75 to 80 cm (30 to 31 inches).
You have to like that style. For me, these types of windows always give a kind of "basement feeling." It should be carefully considered.

@K a t j a .. once again lightning fast .. everything fits really well, except for the staircase right by the front door 😉.

Then let’s rotate it:

Floor plan of a house: living area, office, technical room; dining area with table, staircase.


Floor plan of a residential house with staircase, two kitchens, bathroom with shower and birdhouse.

I’d like to add that I personally prefer the sole orientation toward the garden. Although the plot is quite wide, there are neighbors on both sides. Also, you can see here that having more width with less depth often benefits the rooms.
Maybe the garage could be turned back to a perpendicular layout. That’s nicer for parking bicycles, and there is enough space for it.

Exactly... you can also see that in my sample floor plans. And the staircase is good 😉

I think there are some great ideas here, even if some aspects don’t match the original poster’s preferences. However, many things are, as we know, adaptable.
Here again for reference are the important points.

According to the original poster, a bay window can also be located on the ground floor.

An open staircase in my examples can only be partly open 😉 however, it can still be adjusted in the floor area, and these are only examples, not final plans.

The kitchen in all examples, including those by @K a t j a, is not within the visible area of the living space – that is, the actual living area.

The office can have garden access anywhere (both in Katja’s and my examples).
