ᐅ Floor plan of a bungalow on a slab foundation, approximately 110 square meters

I think we may have been talking past each other. I’ll try to be more specific: My garage is built with a 17.5cm (7 inch) wall right on the property line and is permitted. Would a 36.5cm (14 inch) wall be prohibited because it is insulated? If so, where is the limit?

No, the law does not care about the thickness of the wall you use to build your garage; the main point is that it stays within the critical 3.00 m (10 ft) setback zone and does not cause any structural encumbrance due to its height.

If 36.5cm (14 inch) is not forbidden, then I would have a technically sufficiently insulated room for the equipment. Or where is my mistake?

The equipment room (HAR), especially when located on the property boundary, requires on one hand an insulated space (the equipment must be inside the insulated building envelope), and on the other hand, usually no usage other than garage/carport is permitted directly on the boundary line. The exception is semi-detached houses.

I think the proportions between the room sizes are not balanced.
As already mentioned, the bathroom is far too small for a T-layout.

Good luck

A T-layout works with a room depth of 3.20 m (10.5 feet)

The rooms that are important to me are perfectly proportioned.

Unfortunately, your plan is only roughly dimensioned, but you can see with the naked eye that your planned bathroom is only about 2.7 x 2.6 m (9 x 8.5 ft) in size. Likewise, your pantry has a maximum depth of around 115 cm (45 inches).

The technical equipment located in the utility room, especially when placed on the property boundary, requires an insulated space (the equipment must be housed within the insulated building envelope). Additionally, no other use besides a garage or carport is generally allowed on the boundary line. An exception applies to semi-detached houses.

It will be a technical room, not a utility room

But even a utility room is not a garage 😉
