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.

DIN A4 is a good reference point. I strongly recommend sketching your floor plan ideas by hand. This way, you’ll more quickly realize if you lack a sense of scale and are unknowingly designing an oversized house. Your draft doesn’t show any characteristics of a home where a family allows themselves generous space. Instead, it looks like someone lost the sense of scale. Maybe you should try DIN A5, because on DIN A4 you should actually be able to fit both floors. Could you explain that in more detail? What exactly is incorrectly sized? Where do you see issues? I would appreciate if you could give examples.

That alone should (even if the numbers were realistic) be a clear warning sign: there’s clearly less than ten percent “reserve” before a critical failure. You’d really need an architect whose “@Gerddieter approved” seal had five stars ;-)
Without saying that “everything is bad” here: definitely start again from scratch.
And don’t forget the site plan. Even on a 2,000 sq m (0.5 acres) property, it matters where the house is situated.
By the way: 230 sq m (2,475 sq ft) is a size category for dual-income households with both incomes above the assessment limit! I will leave the feasibility to your concern.
Also, I must disagree: it is not necessary for both incomes to be above the assessment limit.

A site plan with elevation details is the minimum requirement for an assessment.
An aerial view of the surroundings and the development plan would also help.
The house can be more efficient.I will provide the site plan later. The plot is located at around 250m (820 feet).
Can you specify what you think could be done more efficiently? That’s exactly what I want to find out here.

160 m2 (1,722 sq ft) instead of 230 m2 (2,475 sq ft).
Do you already own the property?
Plans should have either north at the top or include a north arrow.

Let me handle the realization.You estimate the house construction costs at 650,000€. How did you arrive at this estimate? Do you already have concrete quotes?
For a rough estimate, this forum usually assumes about 3,000€/m² (square meter). Additionally, for a basement that is not finished as living space, you can expect around 1,000€/m².
With 230m² (2,475 sq ft) of living space and 115m² (1,237 sq ft) of basement, using these figures you end up with 3,000 * 230 + 1,000 * 115 = 805,000€. This exceeds your stated budget. People here are trying to make that clear to you. On top of that, there are additional costs such as landscaping, fittings, and so on.

This is less about whether I can afford it or not. My concern is the planning.Ok. Then just say that the house can also cost up to €900,000 because you have the buffer. Otherwise, there’s no point in discussing it if the project is already dead before the building permit / planning permission is submitted.hanghaus2023 schrieb:

Plans should either have north at the top or include a north arrow. The plot has an 8% slope (descending from east to west), as does the street. The plot frontage is approximately 37 m (121 ft). From the street, the left and right property boundaries run parallel for the first 30 m (98 ft). From there, the right boundary angles inward. The left boundary is a continuous straight line. At the back of the plot, the two boundaries come within 12 m (39 ft) of each other.
