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.

Yes. You will provide a number without clearly explaining how you arrived at it. Please explain how you calculated this value? Good that you ask. First of all, experience shows that houses of this size are not built with cheap or low-cost fittings. That’s a good starting point.
Current construction costs (no, not prefab or turnkey, but classic with an architect or similar) are around 3,000€/sqm (about 279 USD/sqft) of living space, plus extras.
That already amounts to roughly €690,000.
In addition, there is a basement, which for a fully below-ground cellar used as living or utility space costs about 1,000€/sqm (about 93 USD/sqft). If it is included in the thermal envelope or finished, the cost can be higher.
Assuming construction is not “cheap,” I simply add €50,000 (about 46,000 USD) to the house (which means 3,200€/sqm or about 297 USD/sqft). I also allow a buffer of another €50,000.
Excavation work, architect fees, double garage, and so on are additional costs.
P.S. These are estimates based on my professional experience.

Thanks for the very helpful contribution. Ok, I wanted to "provoke" a bit.
At the core, you are planning a quite large house for "normal" conditions and a "normal" budget. And with this actually great opportunity to create "generous" spaces, you have designed a floor plan where the proportions are completely "off" in many places.
Example? A kitchen of 23 m² (248 ft²) is huge,
while a bathroom of 7 m² (75 ft²) is small (but feasible). And a children’s room of 14 m² (150 ft²) is just that. Next to it a children’s room of 18 m² (194 ft²), which I find generous, but given the overall house size, it is appropriate. Then there is a bedroom of 20 m² (215 ft²) (nice!) into which basically no usable wardrobe fits. And a study of 9 m² (97 ft²), which is also modest.
And basically, everyone here is saying the same thing: the design needs to be completely reworked—but BEFORE that, you must know the financially feasible total floor area. They are not trying to be difficult with your budget, but every good architect will ask you this question at the very beginning as well.

The house and the plot of land must be considered together.
