Our dream of a single-family house - feedback welcome

Hello everyone,

we are currently planning our single-family house and are actively following along here, looking at hundreds of floor plans (like all potential builders). Now we have found THE dream floor plan or rather worked on and modified an existing floor plan from a general contractor over the past months until it became OUR floor plan. However, we would still like to get one or two ideas or suggestions here in the forum – an outside perspective is known not to hurt ;-)

Status: The plot has been purchased, the appointment with the architect is scheduled. Cost/effort estimation will follow shortly. We are planning a house in timber frame construction. Below are all the details – we look forward to your feedback.

Development plan / restrictions: available.

Number of parking spaces: 2
Number of storeys: 2
Roof shape: free

Orientation: along the building line. Ridge direction parallel to the street.
Maximum heights/limits: max eaves height 6.5m from lowest ground point (exceptions allowed for slope location).

Requirements of the builders

Further wishes/special features: open, straight staircase as part of the room design, ground floor without stairs and wheelchair accessible.

House design
Who created the plan:
- Do-it-yourself based on a planner from a construction company
What do you particularly like? Why?: everything very open, many windows.
What do you not like? Why?: hallway on the upper floor possibly too narrow.
Price estimate according to architect/planner: follows soon
Personal price limit for the house, including equipment: 350,000
Preferred heating technology: underfloor heating, fireplace, air-/heat pump

If you have to give up, on which details/extensions
- can you do without:
- can’t do without: straight staircase, open design

Why did the design turn out as it is now? Months of planning and adjusting
A mix of many examples from various magazines...

Thank you and best regards
Michael and Babsi

Where are you building?
Should the 350 include garage and additional costs?
Basement with a white tank and/or finished?

We are building in the Hintertaunus, far away from good and evil ;-) Limburg is the next larger town, about 30 minutes away.

And exactly, our naive assumption amounts to about 350 including additional costs and garage, with the latter to be seen as a bonus - depending on how and where we could save elsewhere [emoji6]

Basement finished, no white tub. Possibly only a partial basement. Since we are building on a slope, only part of the basement looks out of the ground or to the front and would be "livable space"

170m² + basement + garage + ancillary construction costs: 170 x 1700€ + 60k + 25k + 50k? I come to 424k. That might also be too much, but I can't imagine 350k all in for the house size...

Wouldn't it be somewhat more sensible to build the garage downhill, possibly even to integrate it into the basement (partial basement)?

Somehow the floor plans don't look as if the stair spaces align vertically. On the ground floor the staircase also looks too short.

Quite a few projections and recesses on the ground floor, what is supposed to become of that on the upper floor? Balconies?

I don't want to be a spoilsport, but have a normally sized (as requested) kitchen island and a normal dining table (90 x 200?) drawn in. To me, that seems too generous for the dimensions.
