Hello,

I have been reading along for some time now and finally dare to share a floor plan here.
First, here is the list of questions:

Zoning Plan / Restrictions

Site plan with blue building structures, green areas and trees


Plot size: 576 sqm (6,200 sq ft)
Slope: Yes, slight. According to the site plan, the top "right" corner is at 295.4 meters (970 feet), lower at 293.88 meters (964 feet), left side goes from 295.17 meters (968 feet) to 293.43 meters (963 feet)
Floor area ratio: 0.3
Building envelope, building line and boundary: Applies to house number 16

Site plan of a building plot with parcels, building areas and street details.


Surrounding buildings
Number of parking spaces: 2
Number of stories: 2 full floors required, plus optional recessed floor (setback floor)
Roof type: Flat roof, max. 5° pitch
Maximum height/limits: Max. 10 m (33 ft) high
Additional requirements: Equipment (heat pump) must be integrated, not external. Maximum of 2 residential units. Specific exterior colors required, rainwater should infiltrate (soil report says this is unlikely). Roofs must be greened. No oil or gas heating allowed.

Client requirements
Style, roof type, building type: Actually, none specified.
Basement, floors: No basement, 2 floors.
Number of occupants, ages: 4 people — 2 adults, 2 children
Ground floor space needs: Daily life (living, kitchen, dining, technical room, guest room)
Upper floor: Family (2 children's rooms, master bedroom, separate bathrooms), home office
Office: Home office, second workspace for occasional use such as a work window sill for example in the bedroom
Guests per year: Currently few.
Open or closed architecture, conservative or modern style: Either is fine.
Open kitchen, kitchen island: We are still considering. Initial wish was separate pantry like in the floor plan. An island would be nice if space allows.
Number of dining seats: Normally 4, rarely up to 8.
Fireplace: None.
Music/stereo wall: Multi-room audio with central unit in technical room.
Balcony, roof terrace: Neither.
Garage, carport: 1 garage
Other wishes: Central vacuum system, laundry chute, smart home (KNX) (I am mostly doing this myself, yes, I am a certified electrician, can program, but will also get additional help)

House design
Who designed the plan:
- Planner from a construction company: Correct, with some input from us. Based on an existing plan.
Price estimate by architect/planner: approx. 485,000 € (euros) for the house, approx. 210,000 € for the plot including basic services (survey, soil report, etc.)
Personal price limit for the house including features: approx. 800,000–850,000 € (including land)
Preferred heating technology: Heat pump

If you had to give up, which details/extra features could you skip:
- Could skip:
- Cannot skip:

Why is the design like it is now? For example:
Standard design by the planner? Yes, with minor wishes from us (wall between study and child’s room 2, T-walls in bathrooms, porch roof, conservatory, pantry)
What do you find especially good or bad about it? So far it seems to fit; apart from possibly the pantry/dining room, we don’t see major issues yet. But that’s why I’m here now.

Floor plan of a house with rooms, furniture, outdoor area and dimension lines.

Floor plan of a single-family house: parent’s/children’s rooms, study, hallway, bathroom, garage.

Floor plan: green flat roof, conservatory above, garage on the left, VELUX windows in the center, dimension 10.96 m (36 ft).


Edit: The furniture shown in the floor plans can be safely ignored. Planners seem to like adding these.

Best regards
Ganneff

How old are the children? Maybe I missed that somewhere.
I mentioned it somewhere already, yes, they will be 11 and 13 at the planned move-in date.

I’m not talking about the stay, but about light through the windows

... while all the windows do need to be revised. In bedrooms and bathrooms, I definitely wouldn’t plan floor-to-ceiling windows; instead, I would go for 2-meter-wide (about 6.5 feet) sill-height windows.

Okay, got it! Is a closet allowed there for storage?
And will there be overnight guests at all? The few could possibly sleep upstairs in the multipurpose room?! Downstairs would be just an office.
Yes, there will be overnight guests, but not very often. I can well imagine having the office downstairs (the 9m² (97 sq ft) are enough), but the family wants me to stay upstairs. Both my wife and child 1 strongly prefer that. But we are still quite flexible for some time, in case there is a change of mind – the electrical planning will make a bigger difference here first. (Okay, maybe the windows too).

Regarding the windows: I’ll review it again. Currently, both children's rooms have floor-to-ceiling windows (one has one, the other has two), the parents’ bedroom doesn’t. The bathrooms don’t have them either. The window in the parents’ bathroom is actually only 82 cm (32 inches) high, the same as the one above the bed in the master bedroom. However, a friend who visited earlier said he would skip that one – too much light entering the bedroom – and also, neighbors could look in.

Above all, the flat roof conservatory is as elegant as Herman Munster’s neck bolt. I consider it a subordinate component that could be exempted, after all, a "greenhouse roof" is a key feature of a proper conservatory. Personally, when reading the development plan, I would have preferred to keep looking for another plot. Municipalities that have no sense of proportion should be met with indifference, not be chosen as your tax residence.
Hmm. I like it here, have for a long time. And suitable plots are really rare in this area.
As for size, the planned conservatory is exempt from greening requirements (under 25m² (270 sq ft)). I think the roof on top comes from the builder’s plan.

And it’s interesting how varied tastes can be; from the pictures, I actually didn’t find it unattractive so far.

Give up the second shower and make the office smaller and the children’s rooms bigger. 12.8m² (138 sq ft) is really tight.
Keep in mind that someday there might be a 16-year-old spending time there; kids don’t stay small forever...
I suggested that earlier, but there was strong opposition – they want a separate bath. They prefer that over more space (keep in mind they are coming from very limited space). Quote: “And then I moved out at 18 or 20, and it’s wasted space then.”

We just sat together and “redrew” the ground floor, based on the version from @ypg. I’m not allowed to move the toilet area “up” to the left because it shouldn’t border the living room, so the rooms at the bottom left stay untouched. The partial wall still extends into the living room; we haven’t agreed on the furniture layout yet. Some kind of partition is needed, and a wall has the advantage that you can easily run cables (power, LAN, lighting, etc.) and also mount things like a TV. Later we want to “play” with the furniture; the kids will make some arrangements, then we’ll see what works out.

The large utility room is nicer this way; now there is also space for a mud sink, which we hadn’t planned before.

The hallway <-> living/dining room won’t be completely open either, so we’re currently thinking about a (wide) glass door, possibly “mounted on the wall.”

Then they study in Fulda or Würzburg or Kassel and cannot find any accommodation. Who knows what will happen and how things will turn out.

I like the process of how you plan together as a family and express your wishes. What will help to find the best solution within the given conditions is imagining different scenarios that are typical for your life, that you want in your life, and that bring you particular joy. Describe these situations without referring to architecture, and then see how they work in one design or another.

Such room divisions can also be created without special architectural elements. There are sculptures, shelves, plants, stoves, lighting installations...
And they can be changed if you no longer like them.

You could be a bit more service-oriented and provide a section of the development plan that clearly illustrates the situation (about 100 m (330 feet) diagonal so that plan sections / knot lines and similar details are visible). What exactly is the "BHL" of the retaining walls?

hm. I’ve liked it here for a long time. And plots in good locations are really rare here.
The size of the planned conservatory so far is also exempt from greening (under 25 sqm (270 sq ft)). I think the roof on top of it is more part of the housebuilder’s plan.

Unfortunately, plots are real estate – you can’t transfer them if the development plan issuer got carried away.

And it’s interesting how tastes differ; from the pictures so far, I haven’t found it that ugly at all.

A flat roof with zero slope brutally exposes the terrain or its modeling, especially combined with a Snow White-style building block (shoebox). The house simply appears roofless in the views. The terrain modeling will not work as drawn; no gutter or drain will prevent stormwater from crossing the boundary here.

I disagree on a very important point: namely, with whom. The draftsman of a prefab house company (or other general contractor) might be a nice listener as a person but is the wrong planning partner in terms of expertise. Given this plot-development plan situation, I consider "Module A" with an independent architect even more essential than usual.

The house appears rather plain and roofless in the elevations.

P.S.: The mounting structure for the photovoltaic system should also be realistically drawn in, instead of just being noted as a text line on the parapet.
