Hello everyone,
we would like to present the floor plan design of our planned house for discussion.
Main questions can be found in the questionnaire.

Development Plan / Restrictions
Plot size: 3600 sqm (0.9 acres)
Slope: yes – south/east facing with a little over 2 meters (6.6 feet) gradient in the house area
Floor area ratio, gross floor area ratio, building envelope, building line and boundary: No development plan, all according to §34 Building Code
Adjacent development: see above
Number of parking spaces: see above
Number of floors: 1 to 3 floors in the surrounding area
Roof type: all types except shed and flat roofs are present in the surroundings
Architectural style: none specified
Orientation: none specified
Maximum heights / restrictions: none
Other specifications: none

Owners’ Requirements
Architectural style, roof type, building type: Gable roof house with a large covered terrace and open design; the roof covering should extend from the balcony over the terrace and transition into a gable roof on the terrace. So no hip roof covering.
Basement, floors: Basement + 2 full floors
Number of occupants, age: 2 adults (34/28)
Room requirements on ground floor and upper floor:
Ground floor – utility room, shower/toilet, kitchen, pantry, dining, living room;
Upper floor – bathroom, dressing room, bedroom, children’s room, office, open area as reading nook (reserved for a second children’s room)
Office: 2-person home office
Guest bedrooms per year: few or none
Open or closed architecture: mixed
Conservative or modern construction: rather conservative. Solid construction (Poroton masonry outside, calcium silicate bricks inside), minimal “ornamentation.” No technical gimmicks. We both enjoy being outdoors, so the covered terrace and large patio doors are especially important to us.
Open kitchen, kitchen island: open kitchen to dining room without kitchen island (we cook a lot, so a powerful extractor hood that vents directly outside is very important)
Number of dining seats: 6–8
Fireplace: yes
Music / stereo wall: no
Balcony, roof terrace: balcony that transitions into the terrace
Garage, carport: double garage in the basement
Vegetable garden, greenhouse: large garden with productive areas
Additional wishes / special features / daily routine, including reasons for choices:
- centralized ventilation system, otherwise simple house technology
- large patio doors (it is sufficient if you can exit from the kitchen door to the balcony and from the dining room window to the terrace; the others (balcony, living room) can be fixed glazing)
- large pantry
- utility room on the ground floor and below the bathroom, since a laundry chute is desired

House Design
Who created the plan:
- planner and our ideas
What do you particularly like? Why?
- almost level access to the terrace and connection to the balcony
- full use of the sunny location
- we really like the floor plan
What do you not like? Why?
- entrance area with a small vestibule on the ground floor acting as a bottleneck; we will probably mainly use the entrance through the garage in the basement anyway
- concerns whether the dining area might be too large
Cost estimate according to architect/planner: none so far
Personal price limit for the house including fixtures and fittings: none yet, still in price determination
Preferred heating system: gas + tank

If you had to give up certain details/finishes
- can you do without:
- cannot do without:

Why did the design turn out this way?
Standard design from the planner: no
Corresponding / Which wishes were implemented by the architect:
- desire for lots of light and still covered terrace
- openness to the large garden
- separation from neighbors on the “right” side through the protruding structure
- built in line with the slope (wider than deep)
What makes it particularly good or bad in your view?
- particularly good because it meets all our requirements but leaves some small doubts as mentioned above.

What is the most important / fundamental question about the floor plan summarized in 130 characters?

We are unsure if there are too many and too large windows on the ground floor, and if the dining area is too big; if so, how to reduce it without major changes.

We look forward to your feedback!
Best regards and many thanks in advance

16 sqm bathroom, but a space-saving tub...

I don’t understand the objection. We are also planning a 12 sqm bathroom and a space-saving tub.
First, we like the look better, and second, the upper body doesn’t feel as cramped.
We don’t want the entire tub to be bigger, because my wife bathes 4-5 times a week, and later the children will too. That would be a waste of water.

Just look at the bathroom. "Imbalance" has already been used for the entire house. That word is a good diplomatic choice. If you are planning that, it’s fine. But here, no bathtub is planned; a seating area is planned.

Number of floors: The surroundings include buildings with one to three floors
On sloped sites, what a layperson might call one to three floors can often legally be clearly two floors.

Thank you all for your feedback.

Note: The plans shown here are our “sketch approvals” of the design planning, intended so we can freely place furniture and experiment a bit. The fireplace is actually missing—that was our mistake.

We are uncertain about how or in which direction to enlarge the vestibule and what size would truly be sufficient. We will mostly use the lower entrance ourselves, mainly because it connects directly to the garage. If we ever have a stroller, it will be stored in the basement, since getting it to the front door would be very cumbersome due to the slope and several steps. So, if the upper entrance is only used by visitors, how large should we plan it?

We understand the concern about the children’s rooms not being the same size. Given our personal situation, we are only expecting one child, but we want to have a fallback option in case of unforeseen circumstances.

The windows in the attached view are smaller than in our drawings (except for the kitchen), and we are unsure which sizes would be better. Also, the bathroom window next to the shower will be frosted glass so that neighbors (who don’t exist yet) cannot admire us in full view. :p

The layout of the hallway on the upper floor is not ideal, that’s true. The space-saving bathtub is not what we want; we want a bathtub of this shape. A standard narrow bathtub is too small for us, and we no longer want a corner bathtub like we currently have in our rental apartment.

Regarding the images:
- Exterior graphic: Please disregard the balcony railing on the left side. This area is planned to be built up with soil and directly connected to the terrace.
- Two pictures show the property facing uphill and downhill. The downhill view faces southeast.
- The aerial photo (oriented north) shows the approximate building envelope and a possible future property boundary in case we decide to sell a part of the land. The driveway is not yet shown here but will be constructed along the lower property boundary.

Please feel free to take a look and share your thoughts.

Another point that currently concerns us: Most window manufacturers have their own in-house brands. However, we have little to no experience with these brands, and the more we read about them, the more questions arise. Visiting window studios is also not easily possible at the moment. With standard windows, we see fewer issues – but who supplies good quality lift-and-slide doors and at the same time panoramic windows like those for the kitchen? Does every manufacturer offer that?

Since you should be familiar with your systems, it’s actually better if window manufacturers don’t accumulate too wide a range of suppliers. Many profiles are licensed from Schüco or Kömmerling anyway. Regarding large and street-facing elements, I generally recommend aluminum as the material. Your kitchen window, with a total width of six and a half meters (21 feet 4 inches), will have to be made in multiple sections anyway. The window factory I worked for was one of the few that could process pieces up to six meters (19 feet 8 inches) in length in one piece. But I imagine that some of these extreme specifications might still be reviewed, unless you have an open checkbook from the central bank?
