ᐅ Carport with green roof and vertical planting on the sides

Dear community,
We want to place an open carport roughly in the front yard, with the long side running parallel to the street.
To increase the chances of building approval from the local building authority, I came up with the idea of creating a green roof for the carport and also adding climbing plants on the sides using a trellis or something similar (this would also provide some privacy from the street and a bit of weather protection). What do you think about this? Is it practical or just a hassle over the years? The carport roof would need to be walkable and this will increase the costs...

I have been researching this in the past few days because we also want an extensively greened carport roof. It doesn’t seem very complicated and appears to be something you can do yourself quite well. Apparently, there are subsidies, low-interest loans, or tax credits available from KFW. I haven’t looked into the details thoroughly yet, as I’m just starting with this topic.

The green roofing itself is simple. You can almost buy it ready to roll out. However, the structure underneath needs to be designed accordingly. The green roof can weigh up to 100kg/m² (20.5 lb/ft²) plus water and snow. This makes the structural requirements more complex than for a typical garage or carport from a hardware store.

I wonder if the KfW also supports garages or carports? I assume their programs are mostly aimed at residential houses.

Possibly, depending on how the building authority is...

It is either permitted or not; it does not depend on the personal mood of the official.

I believe that when it comes to many permits for ambiguous building requests, a certain level of discretion or indeed the goodwill of the authorities (in extreme cases, even a very accommodating official) plays an important role. Looking at what some neighbors on my street were allowed to build and the “chaos” it sometimes creates, one person was permitted to build their garage here, another there; on one side of the street it’s two stories, while on my side it’s just one story, and so on. It only takes new staff moving into the building department for a slightly less strict approach to develop, where they might overlook a minor encroachment of the building envelope or permit a more modern roof pitch. At least, that’s what an architect told me.

In the development plan

Is the development plan actually color-coded there, or is it an old colored sales brochure to help visualize it better?
Why would the carport not be allowed there?
Tip: try reading the fine print of the development plan 🙂

In the plan, the area is actually green, and this "green strip" is intended for all the houses on the street. The strip is labeled "front garden," and the word is underlined in red with the dimension 5.5m (18 feet).

There is no section of text; that is what the building department told me.
