Hello everyone,
After reading quietly for a while and really appreciating all the ideas shared here, I’d like to bring up a topic and hopefully get some feedback, suggestions, and ideas!
I am 34 years old and originally from Munich, where I was born and raised.
Currently, we (my wife and I, with a child on the way, my sister and her partner, as well as my parents) are discussing whether to completely rebuild on our plot of land (currently occupied by a single-family house / 1000 sqm (0.25 acres) / 20 × 50 m (65 × 164 ft) / no zoning plan). The idea is to build a fairly modern house with two spacious living areas (each with its own terrace overlooking the garden, large living and dining areas, etc., and about 200 sqm (2150 sq ft) of living space), including an underground garage and a basement. A granny flat (or accessory dwelling unit) is also planned to be integrated.
I would like to start a discussion based on these ideas and am looking forward to any input or constructive criticism.
Thank you very much.

What I see developing here is, essentially, a fairly typical three-family rental building, with the only differences being that there are no outsiders within the housing community and likewise no external landlord. However, in terms of layout, it will ultimately be the same type of residential arrangement.
It would definitely be interesting to take a closer look at how it was implemented there. It has been quite a few years (>10) since I last engaged deeply with underground garages. If you push the relaxations for small installations to the limit, they become inconvenient to use. Don’t forget: a Pyrrhic victory is not a trivial matter but even more inefficient than the Hornberg shooting.
Double stacker parking systems are also not a cost-saving solution; they are only significantly more space-efficient. Visually, they are basically a repair lift fitted with two towing truck beds and a shaft. You can dress them up to look quite upscale, but in that case, money really must not be an issue.
I would probably most likely consider a setup of three single garages in a row, three parking spaces, and a combined bicycle and trash bin enclosure. In my opinion, this fits best for potential future resale to someone who would use it traditionally as a multi-family house for unrelated parties—unless you plan from the start to design it as three individual condominium units.

Is it possible to avoid an underground garage by building a car elevator?

@RomeoZwo and @ypg. We initially brought up the plan for the underground garage because in two new neighboring developments (plot 1 approx. 890 m² (9600 sq ft) / plot 2 approx. 1100 m² (12,000 sq ft)) an underground garage was built in each case... Basically, I think underground garages are great (if the budget allows). As far as I can tell from the Bavarian Garage Ordinance (Bay. GaStellV.), the size definition is independent of whether it is purely private use or not. The usable area includes both parking space and traffic area. For up to 100 m² (1,080 sq ft), the driveway can be built however you want, which corresponds to an underground garage with 4 to 5 parking spaces.
By the way, for Munich, 1000 m² (11,000 sq ft) for a duplex with a granny flat seems almost generous. I have even heard of duplex plots as small as 150 m² (1,600 sq ft) with 90 m² (970 sq ft) of built floor area under the house.

Surely a good architectural firm should have the ability to create something much more attractive instead of a rather ordinary three-family rental building? I never said it had to look uninspired. But as Yvonne already mentioned, arranging and enhancing the design loosely runs into limits within a building area that is still 14 m (46 feet) “wide” according to setback requirements.

As much as I would like to have a nice penthouse with a rooftop terrace (without a garden to maintain) as a retiree in the distant future, I believe that adding the necessary third staircase (emergency exit!) plus an elevator is a bit too much here (space requirements, costs). Perhaps a skilled architect could design a house with a slightly L-shaped layout (see sketch) that separates the two residential units better than a traditional semi-detached house (to avoid conflicts) and accommodates individual preferences in the floor plan more effectively than a mirrored design. With a 14m (46 feet) wide building plot and an estimated 200m² (2,150 sq ft) floor area requirement for the house (assuming 2.5 stories), the result is almost a square building structure. Slightly elongated, this should offer several creative design possibilities.

I believe that a "penthouse" here can only mean a top-floor apartment spanning two adjacent maisonettes—not a bungalow "on a flat roof as a plot of land."
