Good morning everyone,

we are currently working on the planning of our garage.

It will be a solidly built garage and extension measuring 6x9 m (20x30 ft).

The zoning plan requires a green roof.

We are now facing the "problem" that our plot is sloped according to the terrain survey points.

In reality, it looks to us as if parts of the area were already excavated during site development. In the rear section (see marking), you can see the likely original "natural" ground level.

Construction site with shell structure, scaffolding, standing water and foundation.


Because of the survey points, we are not allowed to build our garage higher than shown in the attached plan, relative to the natural ground level.

In addition, the green roof requires a thicker roof construction, which reduces the interior ceiling height. The design includes a concrete slab with tapered insulation plus green roof.

An electrically operated sectional door from Hörmann (model LPU42) is planned.

Looking at the installation dimensions, I see considerable difficulties in implementing this reasonably with the current design.

The marked door corresponds to the module size. However, the electrically operated version requires a minimum ceiling height of 2,235 mm (7 ft 4 in). With this design, ours is 2,125 mm (6 ft 11.7 in).

If I am reading this correctly, the maximum door we can install at our ceiling height would be the one marked in orange. This would result in a clear door height of 1,775 mm (5 ft 10 in). I really do not want to have to bend down to enter my garage.

Perhaps someone here has faced a similar issue and can share their experience.

Are there any options to get approval to build the garage a bit higher?

What does the designer say about this?

They have already planned for the maximum. The concrete ceiling could be replaced with a wooden beam ceiling. However, this would only gain a few centimeters (inches).

What does the zoning plan or state building regulations say about building on the property boundary?

Does the planner have no better suggestion for the gate?

Excerpt from building regulations: text about building limits, terraces, balconies, and garages

Not really much.

I don’t expect much initiative from our planner regarding the gate. 🙁

And where is the height limit mentioned? That was the main point, right?
