Dear forum members, today we would like to present our floor plan and hope for positive feedback and suggestions on possible improvements. Our basic wish is for a bright house with 4 bedrooms on the upper floor and a living-level basement designed to accommodate 2 offices. We see the basement as necessary, especially due to the sloping site. The ground floor will then provide a spacious living and kitchen area. We have now received the first plans from the architect and would like to optimize them as much as possible with your help. The furniture layouts are only examples and still need to be finalized. Note: The room labeled as an office on the upper floor is intended to become Child 3’s bedroom. The guest room in the basement will be a combined guest/office room. The design of the outdoor areas, such as the terrace and the shape of the new property boundary, still needs to be planned in more detail.
Development plan/restrictions
Plot size: 702 sqm (7,555 sq ft)
Slope: yes, approximately 1.7 m (5.6 ft) higher at the street than at the rear of the property
Site coverage ratio: 0.35
Floor area ratio: none
Building envelope, building line, and boundary: garage minimum 5 m (16 ft) from street, house minimum 3.5 m (11.5 ft)
Number of parking spaces: no requirement
Number of floors: 2
Roof type: gable, hip, or pyramid roof with pitch between 22° and 43°
Orientation: southwest
Owner requirements
Roof type: preferably gable roof
Basement, floors: basement yes, preferably 2 full stories
Number of occupants, ages: 4 (35, 33, 4, and 2)
Room requirements on ground and upper floors: preferably 3 children’s bedrooms on the upper floor
Office: 2 home office spaces desired
Guest stays per year: about 10 times per year from grandparents, hence a guest room
Conservative or modern design: rather modern, I would say
Open kitchen, kitchen island: kitchen island
Fireplace: desirable
Balcony, roof terrace: possibly convert the garage roof later into a balcony
Garage, carport: garage for 1 car with sufficient storage space for bicycles
Additional wishes/details/daily routine, including reasons for choices:
We wanted the 3 children's bedrooms and the master bedroom on the upper floor. Additionally, a small bathroom for the parents there. The basement made sense to us because of the sloping site. It should provide one dedicated office and one combined office/guest room, both with daylight windows. Additionally, a large hobby room for versatile use is desired. On the ground floor, a pantry and laundry room connected to the garage were requested. Later on, it should be possible to convert the garage roof into a terrace.
House design
Origin of the design: Architect based on our detailed requirements (see above).
What do you particularly like? Why?
Our room layout wishes have been implemented.
What do you not like? Why?
The bathrooms on the upper floor and the living area on the ground floor may be too small.
Estimated cost according to architect/planner: not available yet. Probably around 650,000 - 700,000 € (including additional building costs)
Preferred heating technology: air or ground-source heat pump
If you had to give up some details/extras
- Could give up: fireplace, possibly 2nd bathroom on upper floor, walkable garage roof
- Could not give up: 4 bedrooms on upper floor, basement with 2 offices
Why is the design the way it is now?
Our basic considerations were passed on directly to the architect. He has largely implemented our specifications and added some minor touches.
What is the most important/basic question about the floor plan in 130 characters?
We find the existing floor plan generally well done and hope to receive constructive criticism and further suggestions from you to optimize it.

Myrna_Loy6 Dec 2022 22:35In my opinion, the budget does not match the house. Since the basement is a living basement, its construction quality and therefore the construction costs are equivalent to the other floors. These days, even in more affordable areas, the price per square meter is around 3000 €/m² (approximately 280 USD/ft²) for a standard level of finish.
Calculation 1: €700,000 + 20% = €840,000 (Architects often underestimate by about 20%)
Calculation 2: 250 sqm (2,690 sq ft) x €3,000 = €750,000 plus ancillary construction costs €50,000 plus double garage €35,000 = €835,000
These are just estimates… 😉
The slope is not really a reason for a basement. It will be leveled out by the fill.
Regarding the floor plan: it is a pity that you cannot access the garden directly from the living area, only through the rather small doors on the terrace.
And the kitchen is definitely too small: there is no space for tall cabinets.
Drainage for the children’s bathroom should avoid passing through the dining area. Otherwise, solid, if you disregard the estimates.

Sunshine3876 Dec 2022 22:39I find the prices to be highly exaggerated. A good architect wouldn’t miscalculate by such a large margin. One quote might be 10% higher and another 10% lower. A basement doesn’t cost €3000 per m² (even including a basement hobby room). I would estimate more along the lines of 3k x 160 m² (1750 ft²) = 480k plus 120k for the basement = 600k. Plus additional construction-related costs. The total estimated by the thread starter is actually quite reasonable. The garage could also be a prefabricated garage.

I would rather estimate 3,000 €/sqm x 160 m2 (1,722 sq ft) = 480,000 € plus 120,000 € for the basement = 600,000 €. Plus additional construction-related costs. The total estimated by the original poster is already quite accurate. You mean it’s possible to build a residential basement for 1,500 €/sqm (about $140/sq ft)? 😀

And you think that it costs the same as for an above-ground floor?Does the electrical outlet in the basement cost less? The doors? The floor coverings? The earthworks? Possibly required waterproof concrete? Light well? Disposal of excavation material?Similar topics
