Dear community,

We are finally getting a step closer to realizing our dream of building a single-family home.
The plot has been purchased, building plans have been reviewed, construction method decided, and so on. We have now commissioned the architect of the general contractor (GC) of our choice with the planning task and are currently fine-tuning the house design. I would love to take you along on this journey and incorporate your valuable feedback.

At this stage, the focus is on the house design.

Basic data:
Plot: 1062m2 (11,433 sq ft); approx. 25.5m x 41.64m (84 ft x 137 ft)
Orientation: Northwest -> The arrow in the screenshot of the 3D view points south


Desired room layout:
Ground floor:
  • Large living/dining area with adjacent (but separable) kitchen at the bottom left, plus a gallery overlooking the first floor
  • Utility room
  • Guest toilet
  • Garage
  • Separate apartment at the top right with its own entrance for parents-in-law

First floor:
  • Gallery overlooking the ground floor
  • 2 children’s bedrooms with a shared bathroom
  • 1 playroom (initially a home cinema room, later to be repurposed) above the garage
  • Master wing with main bedroom, dressing room, and bathroom

Attic:
Note: I am still discussing this with the architect. Due to the hipped roof shape, the actual living area has shrunk too much. Therefore, further discussion is needed to accommodate the other rooms. I had underestimated the ratio of gross floor area to usable living space.
  • 2 separate offices
  • 1 guest bedroom
  • 1 small guest bathroom

Basement:
  • 1 technical room
  • 1 laundry room
  • 1 storage room
  • Large fitness room
  • Wellness room with sauna

Additional plans:
  • Air-to-air heat pump or air-to-water heat pump
  • Photovoltaic system with/without battery storage
  • Possible pool (3.5/4m x 8m or 3.5/4m x 12m) with heat pump (and countercurrent system)
  • Sauna in the basement room
  • Air conditioning for various rooms
  • Smart home system – most likely via KNX
  • Garden: Currently planning 2 terraces – one to the left, slightly more to the south, and one facing the main part of the plot further north

Now to my first questions for you:
  • How do the floor plans strike you? Do they make sense in terms of the dynamics of family life?
  • The location of the separate apartment was chosen based on our wish. We wanted a strict, clearly defined spatial separation with a separate entrance. Do you have any comments on this?
  • Do you consider the utility rooms in the basement to be adequately sized (considering KNX, heat pump, etc.)?

My biggest construction challenge at the moment is the layout of the attic. There are two alternatives:
- Change the roof type, which would increase costs but provide more usable living space in the attic
- Give up the playroom on the first floor, convert it into a guest room, and build only the two offices in the attic (no guest room or bathroom)

Thank you in advance for your comments.

A quick question about the site plan: is the red line the garage boundary?

Correct!
ypg schrieb:

What about the "extension area" as boundary construction outside the red line? What was allowed back then and what is allowed now?

Above the left red line is a very old shed. It was built right on the neighbor’s property boundary. The xx marks in the drawing indicate that, according to the old zoning plan, a similar building is no longer allowed directly on the boundary after demolition.

In general: The architect has included 3m (10 feet) setback distances from all neighboring properties in the current plans.

But the building envelope is also limited on the sides, right? I see a 6-meter (20 feet) setback to the west and 4-meter (13 feet) to the east. Why 3 meters (10 feet)?

Please excuse my critical approach. You have a site plan or location plan, and the architect is doing what he wants or what you want.
This is not a case of “wishful thinking” or “throw away the zoning plan because I can’t fit my dream house on it.”
What did the building authority say about the overall footprint exceeding the limits?

To be honest, I had 3 meters (10 feet) in mind, but I might be mistaken. I saved the architect’s statement "setback areas are accounted for in the plan" and didn’t look into it further. However, if I subtract the setbacks of 6 meters (20 feet) plus 4 meters (13 feet) from the total width of 25–26 meters (82–85 feet), the total width of the house with the garage (11.10 meters (36 feet) + 5.63 meters (18 feet)) roughly fits. So it seems to be okay.

The idea was to finalize a plan now, submit some additional supporting arguments (neighboring houses), and then wait for the preliminary inquiry. We will respond accordingly after that.

Just my opinion: you have a great budget, and there is so much more potential than just tweaking this design a bit. I believe it will never be as good as having it completely redone. By a professional architect, that is.
We were in the initial phase with two construction companies that have in-house architects. They drew us nice and perfectly livable floor plans. That would have been satisfactory for me.
Then, lastly, because we liked the style of his houses, we consulted an independent architect. And what can I say—the difference blew us away.
The arrangement of the windows, the sight lines, the smart details, and the consideration of our wishes fully convinced us; and not least, the honest feedback on some of our impractical ideas.

Yes, it can be more expensive, and the architect needs to be paid. But your budget allows for the house to be not just nice but really great in the end.

I had house examples where the granny flat was located on the ground floor of the main house – I didn’t like the results because the main floor plan on the ground level suddenly became cramped (small).

But that will also be the case for you if you strictly follow the numbers.

That roughly matches the total width of the house with garage (11.10m + 5.63m). So it seems to be okay.

No! 16.73m is not 15.5m!
Who is your general contractor? Otherwise, as I said twice already, I agree with @Elokine

I would NEVER have a villa costing around 2 million built by a general contractor based on an existing development plan. That would be like using the money for a Maserati to upgrade a Tuareg.
