Hello everyone,
Zoning plan/restrictions: Zoning plan and restrictions considered by the architect
Plot size: 675m² (7260 sq ft)
Slope: yes, running diagonally across the plot (see elevation plan)
Building window, building line and boundary: 3 m (10 feet) on all sides
Edge development: yes, neighbor to the southeast
Number of parking spaces: 2 in garage and 2 in front of garage
Number of floors: 2.5
Roof type: gable roof, 36 degrees
Architectural style: simple
Orientation: southwest
Maximum heights/limits: same as neighboring buildings, sufficiently high
Other requirements: none
Street: cul-de-sac; our house is at the end, with neighbors on one side and open view of forest, meadow, and valley on the other
Owners’ requirements
Style, roof type, building type: interior as open and straightforward as possible, exterior simple
Basement, floors: basement, ground floor (GF) and upper floor (UF)
Number and age of occupants: currently 2 (both 28 years old), planning 1-2 children
Space requirements for GF, UF: approx. 140 m² (1507 sq ft) of living space
Office: absolutely necessary due to 80% remote work
Guest bedrooms: very rare use
Open or closed layout: open
Conservative or modern construction: conservative (mostly because it’s usually more affordable)
Open kitchen, cooking island: open kitchen with bar or island (due to space and layout, more likely a bar)
Dining seats: 4-6
Fireplace: planned but not mandatory
Music/stereo wall: standard TV wall
Balcony, roof terrace: small terrace on the slightly extended garage towards southwest, terrace towards southeast
Garage, carport: double garage with a single door
Utility garden, greenhouse: standard
Other wishes/notes/daily routine, including reasons why some things are wanted or not: a small shower in the guest WC is very important to us, as well as a small room for the home office. Since I work from home 80% of the time, this is essential. Also, a small storage room for vacuum cleaner etc.
House design
Who designed it: architect
What do you particularly like? The dining and living area looks bright and cozy in our opinion. Not too big and not too small with a great view.
What don’t you like? Why? Bathroom layout feels too tight and awkward, hallway in the upper floor too narrow?
Preferred heating system: air source heat pump
If you had to give up some features, which ones?
Fireplace
Why did the design end up like it is now?
The original design was larger and included more details such as corner and roof windows, but it was optimized for cost.
However, the room layout and overall room concept basically remained unchanged.
What is the most important/basic question about the floor plan summarized in 130 characters?
I would appreciate further suggestions, especially regarding the aspects we don’t like. Overall, we are quite happy with it. Do you see any major “no-gos”?
If any information is incomplete or unclear, I’m happy to check it again.

hampshire14 Oct 2021 22:20I never get tired of saying that there is no law forbidding multiple terraces. We live quite well with several places to sit on our hillside.
@Arango18 The initial cost estimate sounds very optimistic to me. I would have guessed around 750k for the house, so it would be great if it stayed within your budget. Keeping my fingers crossed.

And where is it planned now? There isn’t much space in the middle of the hallway… how do you imagine that working with two children? Leaving it out doesn’t help!
As shown in the floor plan, it is located in the hallway. I think we can slightly adjust the width of the hallway. A recessed niche is not an option.
The storage room will be used, as mentioned, for the vacuum cleaner and all the other miscellaneous items.

@Arango18 The initial cost estimate sounds very optimistic to me. I would have expected closer to 750k for the house alone, so it’s great if it stays within your budget. Fingers crossed. 750k for a 145 sqm (1,560 sq ft) house with a basement only?
Could you please explain your calculation in more detail?
Thanks for the good luck wishes 🙂

A niche is out of the question.That’s not a Plan B. As I said before, there is no coat storage, each child uses about 2-3 pairs of shoes, jackets too... maybe you only have one pair, but your wife probably changes shoes every day. Do you want to always have to get them from the basement just to step outside the front door?
I’m not trying to be difficult, quite the opposite.
The thing shown in the hallway is just an obstacle there and a makeshift spot for handbags and shopping bags.

Could you explain your calculation in more detail?It’s not a calculation, just a rough estimate. Over 200 sqm (2,150 sq ft) of heated building envelope on a hillside at around 3k per sqm (0.28k per sq ft) including significant earthworks, retaining measures for the slope, plus a buffer for unfavorable soil conditions—I would set aside about 750k for that.hampshire schrieb:
This is not a quote, just a rough estimate. Over 200 sqm (2,150 sq ft) of thermal envelope on a slope at around 3,000 €/sqm (about $280/sq ft) with significant earthworks plus retaining measures for the slope and a buffer for unfavorable soil conditions—I would set aside approximately 750,000 € (about $835,000) for that.Ah, okay 🙂
We hope the earthworks and soil disposal will remain manageable due to our own work and partial reuse for backfilling (for example, to the left of the house for the entrance area).
My rough calculation is more like this: 2,150 * 145 = 312,000 € (about $346,000) + 80,000 € (about $89,000) for the basement + 15% additional construction costs = 450,000 € (about $499,000) - 50,000 € (about $55,000) for own work = 400,000 € (about $444,000).
The 15% additional costs are lower because we have already paid all extra costs for the land, so only construction phase additional costs apply.
The own work is because we can do a lot ourselves (electrical work up to inspection, much of the interior finishing, a friend with an excavator who works in civil engineering, roofing ourselves, assisting with the shell construction).
But as I said, we’ll see what the calculation or the architect says. I can estimate as much as I want, but we have a good professional we pay to calculate everything properly.
And yes, I know that usually people calculate with 2,500 to 2,800 € per sqm (about $275 to $310 per sq ft) here, but as mentioned, we are not building in Bavaria or Baden-Württemberg or near a metropolitan area.
I would welcome further suggestions for the floor plan. So far, I have taken the following into consideration for implementation:
- Widen the upper corridor by removing the entrance areas to the bathroom/bedroom
- Slightly widen the lower corridor, move the wall more toward the living room to make space for a wardrobe
- Consider tall kitchen cabinets
- (Possibly) mirror the floor plan
