Terraced house on a 240 sqm plot - fundamental questions / feasible?

Great, many thanks for all the opinions and suggestions!!!

As already wrote, the roof terrace would already be relevant with a 240 sqm plot size. Not to look over the neighbor’s plate from there (there has been nothing on that side for 8 years anyway), but simply to have a second paved outdoor area. The garden is small enough anyway.

The development plan explicitly states the following for us:

A2.2.4 In WA1, the permissible building height for garages and carports is limited to a maximum of 414.00 m above sea level. The upper limit of the roof surface (upper edge of roofing, ridge, parapet, balustrade top edge) must not exceed this dimension.

and

A3 Construction method (§ 9 paragraph 1 no. 2 Building Code in conjunction with § 22 Land Use Ordinance) According to the plan description - usage template, it is determined:
a: deviant construction method: Only detached houses with a single-sided party wall on the eastern property boundary and an attached garage/carport on the opposite property boundary are permitted. On all boundary garages / carports, the installation of roof terraces is permitted.

In the justification:

According to the urban development concept, a dense development in the form of terraced houses is to be created along the street. Therefore, a deviant construction method is planned for this area, so that a residential house and a garage or carport are always alternately constructed (see also local building regulations no. C 2.1.3 "Facade design"). Permissible roof terraces on garage buildings in WA1 are intended to improve the residential quality on the rather small plots by providing the possibility of expanding the usable outdoor area through inclusion of the garage roof.

Since the zero line is at 410m, and the height of garages is limited to 414m, our understanding so far has been that 4m would be okay. The consultant said that this was also the "wish" of the development plan. I am curious what will be stated later in the protocol.

A roof terrace is typically a second terrace for the Caipirinha during the romantic medical novel in the evening sun, and rather no adequate substitute for a firstterrace, which, as the name suggests, is usually on the ground floor.

Whether one really likes a stand with a view of a lawn without goals, I would put a question mark behind that.

We are not dealing with a hillside location here, where the floor above the valley level would be the garden floor, but here it would make little sense to "raise" the living floor to the terrace level, since then the ground-level garden access would be in the sleeping floor.

Therefore, I do not think that rose-colored glasses are enough to drink a small property objectively beautiful.

From my point of view, this roof terrace would only be a disproportionately large - and thus making the ensemble appear even smaller overall - bedroom balcony.

I think it depends on the design. With complete greening, it would create an additional small oasis, which can certainly have value. Of course, it must be permitted and affordable for the OP.

I see it the same way. Based on your development plan excerpts, I cannot identify any contradiction in the development plan. Perhaps the caseworker at the building authority is somewhat overwhelmed by the terraced houses.

Like in the picture example? - there the little roof is probably just a tiny bit bigger than the entire property here, I wonder if that still "works" at this scale?

There are small and large plants. Often, green roofs are welcomed by cities because they improve the climate.
