ᐅ Single-family house floor plan, 2 stories with basement, approximately 190 m² living space, plot size approximately 440 m²

Hello everyone,

we are still in the planning phase of our single-family house and have been experimenting a bit with a freeware floor plan program. We would like to get your feedback.

But first, the questionnaire:

Development plan/restrictions
Plot size: 440m² (4,736 sq ft)
Slope: approx. 2m (6.6 ft) over 20m (66 ft) to the east and approx. 2m (6.6 ft) over 20m (66 ft) to the south
Floor area ratio: no development plan available, building according to §34 Baugesetzbuch (German federal building code), so floor area ratio 0.4
Floor space index: see above: 1.2
Buildable area boundaries: north (toward street): approx. 2m (6.6 ft), west: 3m (10 ft), south: 3m (10 ft), east: 6m (20 ft) to the immediately adjacent neighbor’s building, otherwise 3m (10 ft)
Edge development: yes, neighbor to the east
Parking spaces: 2 in garage and 2 in front of garage for guests
Stories: 2 full floors
Roof type: hipped roof (all types are permitted)
Architectural style: modern (all styles are permitted)
Orientation: garden facing south
Maximum heights/limits: same as neighboring buildings, tall enough
Other requirements: none
Street: very narrow, dead-end

Homeowners’ requirements

Basement, floors: basement, ground floor, and upper floor
Number of occupants, age: currently 2, planned 4
Space requirement ground floor, upper floor: about 60-70 m² (650-750 sq ft)

Other wishes/special features/daily routine, including reasons why some things are wanted or not: guest room and guest bathroom in basement, laundry room on the upper floor

House design
Who planned it: DIY
What do you especially like? Why?: upper floor bathroom and bedroom facing the garden (near the forest edge), separate entrance area with cloakroom so cats can’t run outside the front door, laundry room on the upper floor
What do you dislike? Why?: bathrooms are not stacked vertically, so the drains are under the living room, but we accept that
Preferred heating system: air-to-water heat pump with or without ventilation system

If you had to give up something, which features or extensions
- can you give up: basically nothing 🙂

Why did the design turn out this way?
We sketched out our specific wishes and then made sure they fit within the built-up space.
What do you think makes it particularly good or bad? I hope it will be comfortable to live in.

What is the most important/fundamental question about the floor plan in 130 characters?
How do you like the floor plan? I’m happy to explain our thinking behind particular features if you have questions.
Would the drains under the living room be very noticeable? I think they might be hidden with furniture (possibly DIY). Those black squares in the drawings indicate drains or ventilation shafts.

I plan to present this design to various general contractors. An architect is not an option for various reasons. Please avoid discussions about why we chose general contractors over an architect.

Due to the neighbor’s building on the boundary and the building authority’s instruction that we keep 6m (20 ft) distance from their house wall, we want to place the garage adjacent to their wall (with appropriate foundations, of course, so no pressure is exerted on their basement wall). The garage is about 1m (3.3 ft) lower than the house to reduce the slope from the street to the garage. That’s why I integrated this corner into the ground floor and basement so one can walk down a few steps from the front door to the garage. Possibly, a passage to the garage could be made at the stairs if the height levels work out. The staircase will be a half-landing staircase, but the program cannot display this. From the front door to the street, no steps are necessary; a ramp should suffice.

In the basement, the utility room and hobby room will have light wells, and the guest room/office and bathroom will have a light court. Guest room and office can be combined; it only needs space for a bed, a wardrobe, and a desk.

We look forward to your suggestions!

Good luck Tortuga123
