House Design
- Who planned it: -Do-it-Yourself
- What do you especially like? Why?
Double landing staircase, kitchen and dining in the south, circulation area on the northeast side; large glass area in dining room facing garden, G-shaped kitchen, enlargement of children’s rooms with dormers; hallway should hopefully feel generous although it could be a tad wider
- What don’t you like? Why?
No space for a urinal in the ground floor bathroom
Basement planning not yet good we think, how to separate a later sauna room well?
Personal price limit for the house, incl. equipment: €425,000
- Preferred heating technology: air-to-water heat pump/trench collector + controlled residential ventilation with heat recovery + underfloor heating

If you have to waive something, which details/extensions
- can you do without: exposed roof truss
- cannot do without: shower in ground floor WC; staircase with straight steps; staircase entrance outside dirt area; wardrobe

Why is the design as it is now?
Read a lot of floor plan reviews here, input from builder friends; felt like 100 hours drawing floor plans
- What makes it particularly good or bad in your eyes?
In our view very good use of space for a relatively small house, pleasant hallway layout

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

Is this floor plan practical as it is?
Are there show-stoppers we might have overlooked?

Attached are own drawings from SketchUp / site plan from the development plan
Our plot would be number [9]

Note: Unfortunately the windows are missing in the upper floor. There are planned 150x138cm on the gable sides, the dormers approx. 200x138cm each, and additionally a double casement window 78x160cm in the staircase, parents’ bedroom and bathroom

Baa, I actually wanted to quickly introduce us, but I can no longer find the edit button. The plot of land for the house is as good as purchased, the notary appointment is soon. Please share all comments and thoughts honestly, we look forward to every input and/or creative suggestion.

Please upload the floor plans in jpg format directly here. Thank you

Very gladly

the one in the living room is our current couch and next to it are two speakers. TV and speakers + subwoofer in the front are not shown.

Just three spontaneous things:

Only a mini window in the living room?
As soon as you have a child, you’ll do more than just watch TV there

Light well 3D doesn’t fit the plan or do I have a comprehension problem

I find the asymmetry of the gables very unusual. Mhmm. But actually it doesn’t matter. Unsure.

Hi, you are completely right! We are still very undecided about the basement. The window situation in the living room is not ideal, but the options are somehow only: window behind the TV or window on the north side :/ The double door to the dining area is 2110x1960mm and mostly made of glass. The window should be a 1300x2300mm patio door, where the late afternoon/evening sun then shines in. We initially had the gable symmetrical but then the staircase is over 4m high with an unreachable window.
