What do you not like? Why?: due to space constraints the carport is elongated for two vehicles, cannot have a continuous side wall because of bordering development, caravan should also fit there
Utility room is far from house connections
Preferred heating technology: air-to-water heat pump with heat recovery, planned by Tecalor

Why is the design the way it is?
- Standard design from the manufacturer with personal adjustments by planner/manufacturer
- Which/what wishes were implemented by the architect? Cathedral ceiling, dressing room, room layout
- What do you think makes it particularly good or bad? Fits our needs best based on current considerations

Hello everyone,
After a few weeks of reading along, I registered today. It’s very interesting to see the wide range of requirements and wishes.
Our project is planned to start as soon as possible, and we would appreciate opinions and suggestions on what could be done differently or better.
Basically, the design matches our ideas and wishes, but we are looking forward to hearing your thoughts.
The building site is in Heilbronn district, Baden-Württemberg.

Regards
Kalter.Kaffee

We currently have 3 bathrooms, which is too many for us. One of the reasons we are building is also to downsize.


I can totally relate to that! If I had to save square meters, a second toilet would be gone as well. Many don't understand this here.

We considered having a window in the dressing room, but because of the ventilation system, it is not necessary.

Light! Having to turn the light on every time is not nice. A window doesn’t cost much. It could be a higher-placed or frosted window.

Slope about 1.5 m (5 feet) from the road

Are you sure? Is there a current elevation plan? According to the zoning plan and sewer planning, it looks like only 50 cm (20 inches), with a 2 m (6.5 feet) slope over the full length of the property.

Number of floors: not specified

It is specified. Two stories. Since it’s not mandatory, of course that may not matter to you.

due to boundary development, cannot have a continuous side wall

Are you sure that wall openings help? I know it usually works like this: carports are assigned a fictitious wall.

max 1 m (3 feet) fill allowed

Text excerpt from the zoning plan:
3.3 Terrain alterations
Embankments and excavations on the building plots are permitted up to a maximum total height of 1.5 m (5 feet) compared to the natural terrain

How much fill is planned, then?

tends to be 4-5 m (13-16 feet) from the curb

With my interpretation of the elevation from the zoning plan, this would work—not with a 1.5 m (5 feet) slope.
4 m (13 feet) * 15% = 0.6 m (2 feet) maximum height difference
or the other way around
1.5 m (5 feet) / 5 m (16 feet) = 0.3 = 30% > maximum allowed slope of 15%

Yes. Two stories. Since it’s not mandatory, it might not matter to you, of course.

Are you certain that wall openings will help? As far as I know, carports are assigned a hypothetical wall.

Text excerpt from the site development plan:
3.3 Terrain modifications
Fill and excavation on building plots are permitted up to a maximum total height of 1.5m (5 feet) above the natural ground level.

How much fill is planned exactly?

According to my interpretation of the elevation from the site development plan, it would work, but not with a 1.5m (5 feet) embankment.
4m (13 feet) * 15% = 0.6m (2 feet) maximum height difference
or the other way around
1.5m (5 feet) / 5m (16 feet) = 0.3 = 30% > maximum allowed slope of 15%

What happens if some areas exceed that, for example 20%, and average out to 15% after paving?

What happens if there are sections with more than that, e.g. 20%, but on average it is 15% again after paving?

The legally required 15% maximum slope for medium and large garages does not apply to small garages. Nevertheless, it should not be exceeded according to recognized technical standards. This is also in your own interest to avoid slipping on black ice or difficulties when exiting. A 20% slope is still considered practical, although you need to pay close attention to transitions since some standard vehicles might scrape the bottom.
§3 Garage regulations
(2) 1 Between a public traffic area and a ramp with more than 10 percent slope, there must be a surface at least 3 m (10 feet) long with a slope of no more than 10 percent. 2 Exceptions may be permitted for ramps of small garages if there are no concerns related to traffic safety or order.
If the exception is not granted, the carport must be positioned further back. And further back means lower as well.

Thank you.
Cars do not sit low. Only the main entrance needs to be wheelchair accessible, and for that, part of the yard must be built up.
Parents and parents-in-law have over 30%.
This is not unusual here.
That’s why I was surprised.
