Hello,

we are planning a new build and have put our ideas into a floor plan. We would greatly appreciate any suggestions for improvements.

Development Plan / Restrictions
Plot size: 2000m² (21,528 ft²)
Slope approximately 8% (east to west)
Site coverage ratio approximately 110m² (1,184 ft²)
Floor area ratio 3 (including basement)
Building envelope, building line and boundary: sufficient space
Edge development: no
Number of parking spaces: 4
Number of floors: upper floor full storey
Roof shape: -
Architectural style: -
Orientation: see plan
Maximum height/limits: < 300m² (3,229 ft²) footprint / 2 full floors

Client Requirements
Style: modern, gable roof
Basement, floors: basement, ground floor, upper floor
Number of occupants, age: 2 adults, 3 children = 5 persons
Space requirement ground/upper floor: approx. 110/120m² (1,184/1,292 ft²)
Office: family use and home office (2 workrooms)
Occasional guest bedrooms: space for 2 persons (planned in the ground floor workroom)
Open or closed layout: tendency to open, only the kitchen should be separable
Modern construction method
Kitchen island
Number of dining seats: at least 10
Fireplace: no
Music/stereo wall: no
Balcony/roof terrace: possible on all sides, main direction north but also west and in front of the house to the south
Garage/carport: planned on the right in front of the house (starting from the WC to the right, so a covered walkway to the front door is possible)
Utility garden, greenhouse: utility garden located in the north
Other wishes/special features/daily routine, including reasons why some things should or should not be:
Space between children’s room and parents’ room, short walking distances
Street is on the south side

House Design
Who designed the plan: DIY
What do you especially like? Why? The entrance vestibule is important to us. The kitchen should be comfortably large because it will be used a lot (often two adults and children). A double garage is planned next to the front door, starting with the WC (to the right). The hallway will be illuminated during the day by glass doors (ground floor) and hallway/bathroom windows upstairs, as well as a glass door in the workroom.

What do you dislike? Why? Unsure if the entrance vestibule is adequately sized.
Price estimate according to architect/designer: own estimate: 650k EUR
Personal budget limit for the house, including fittings: 700k EUR
Preferred heating system: heat pump (in basement)

If you had to forego certain details or extensions
- what can you give up: floor size
- what can you not do without: kitchen, children’s rooms, storage room, workroom 1, workroom 2, basement

Why is the design the way it is? For example:
A mix of many examples from various magazines...

What is the most important/basic question about the floor plan summarized in 130 characters?
We have created several floor plans. We like this one but are sure many optimizations are possible. We welcome any suggestions or critiques.

Okay. Then just say that the house can also cost up to €900,000 (about $975,000) because you have the buffer. Otherwise, there is no point in discussing it if the project is already dead before the building permit / planning permission is applied for.

Yes, the construction costs are important. However, this thread is not about construction costs. I am focused on finding an optimal floor plan, preferably based on the approach I suggested. But I am open to being convinced by something completely different.

Please help me see where I can improve. Where are rooms poorly or inefficiently sized? Are corridors too small or too large? Does the staircase need more space? Is a children’s room of 16 m² (172 ft²) excessive?

I should possibly have mentioned earlier:
Own work contribution:
- Tiles in the basement
- Flooring (except tiles on the upper floor / ground floor)
- Wallpaper / interior painting
- Garden work (100%)
- Interior doors

Why discuss an optimal floor plan if you don’t have the money for the house? You need to consider both together, or actually, the budget comes before the floor plan.

So, once again the question: Can you afford the house for €900,000 (plus additional costs) or not? If not, the thread can simply be closed. Because saving a few square meters often ends up ruining entire floor plans.

An 8% slope in the building plot is not a minor issue. This fact alone requires significant reconsideration, especially for the basement or semi-basement areas.

And just as @KarstenausNRW already pointed out: the floor plan and budget are interdependent. It’s not possible to consider them separately. There is a reason why this forum provides a questionnaire for beginners. Please fill it out, and the attitude of "Let me handle that" comes across a bit off here (I’m hinting politely that you might be discouraging potential helpers).

For me, it’s less about whether I can afford it or not. It’s about the planning.

I’ve been here long enough to confidently say that for most of the regular helpful contributors, it is quite important whether a construction project or just a hopeless fantasy is being discussed. If someone needs a little push or encouragement, help is gladly given. But no one is allowed to head for disaster. This is not a bug, it’s a feature ;-)

Also, I have to disagree: It’s not necessary for both to be above the assessment threshold.

My mistake. What I meant was: “... provided you like to sleep soundly and don’t need the thrill of fear about your existence.” I myself live in the jurisdiction of a very nice bailiff — still, I prefer her to ring the doorbell elsewhere. Professionally, I advise homeowners only, but as a volunteer, I also assist debtors. That sharpens the view for tightrope walkers ;-)

If you looked at your design with planning experience, you’d notice this right away. But even a staircase inserted only as a symbol is difficult for @kbt09 to assess ;-)

Yes. You are throwing out a number without clearly explaining how you arrived at it. Please explain how you came to this figure?
