ᐅ Preliminary Planning for House and Garage BEFORE Purchasing the Land

Hello dear forum,

Until now, I have only been a silent reader here, but now it’s our turn to plan our house construction.

I have been researching the topic for several weeks, watching various tutorials, talking to acquaintances who have already built homes, and I believe I have understood the basics well enough to start with rough planning.

We have now found a plot of land that we like in terms of location, but we are still unsure whether our plans can be realized there. The plot (860 sqm (9,255 sq ft)) is nice but has a slight slope (1-2 meters (3-6.5 feet)) and unfortunately a somewhat awkward shape including building boundary lines.

We are now asking ourselves how and from whom we can get a qualified preliminary plan for
a) the arrangement of the house and garage and
b) the external design of the house (building height, bay windows, roof angles, etc.) while respecting the local development plan / zoning requirements.


Since the purchase of the land depends on this, we would like to have it evaluated in advance.
Do architects offer such services beforehand (possibly for a planning fee)? Or would we have to sign an architectural contract covering all project phases right away? Does it have to be an architect, or are there other professionals to contact? Or is it generally common to buy plots "blind" and then figure out the detailed possibilities afterward?

We would be very grateful for opinions and experiences regarding a sensible approach.
Best regards

As I understand it, the eave height is defined here as the intersection between the exterior wall and the roof covering – not the height of the gutter.

Finally, someone is getting it right – and a professional would never say the latter. The eave height is basically the cut-off point if you imagine the roof covering as an avalanche melting off the roof overhang [I should probably apply for utility model protection for this explanation, LOL].

How would you assess these requirements for our project? Since the measurement is taken on the valley side and the eave height is measured at the roof covering, I’m a bit concerned that the house might end up being too low in height, including the basement. Is this concern justified?

Could someone possibly also comment on my design from post #12?

The professional has already indicated that the concern is unfounded:

No problem with two permitted full stories and a 6m (20ft) eave height.

If they are dormers, they are allowed on the valley side as well, provided they comply with size restrictions.

perhaps there is still a chance if one of the neighbors already has it?

If these are cross gables, you could try knocking on the door and ask for the planner who obtained the exemptions.

Correct. But it is 6 m (20 ft). This is enough for two floors plus an attic on a flat plot.

Garage with space for trash bins and gardening tools.

You might need to keep a 3 m (10 ft) distance from the sidewalk with a garage. The clause “or its lateral extension” in section 1.3 of the written regulations is confusing. How does one extend an area? And sideways? Without defining a directional reference, this wording doesn’t make sense, especially on corner plots.
Otherwise, there aren’t many alternatives. Here’s a bold counterproposal:

Site plan: orange-colored building on plot, blue border, yellow extension, surrounding houses.

Rotation against the specified ridge direction is justified by the atypical shape of the building boundary and optimization for photovoltaic panels. A carport is also allowed outside the buildable area.
