ᐅ Narrow house on a narrow hillside lot

Dear community,

I would appreciate your ideas and assessments on a rather special building project:

We have a narrow (10 meters wide (33 feet)), but quite long (60 meters (197 feet)) garden plot that we could build on (positive preliminary building approval).
Due to the conditions, we are uncertain whether building here is really feasible, if we would have to make too many compromises or restrictions, or if the costs would simply get out of hand.
It is a sloped plot facing southwest. There is no development plan, and many single-family homes are located nearby. Setback distances must be observed, and the neighbors are not willing to waive any rights.
So, if I understand the setback regulations correctly here in Bavaria, one could only build 4 meters (13 feet) wide, but with several floors over a length of 16 meters (52 feet).
Because of the slope, there should be some creative possibilities, for example with staggered building volumes, roof terraces, and so on?!
Or is it only suitable for a tiny house for garden enthusiasts?

Thanks in advance for your thoughts!

4 m (13 feet) minus walls results in a room width of about 3.2 m (10.5 feet), depending on the wall construction. I wouldn’t want that.

Either you have walk-through rooms, or you have to build upwards. Staircase in the center and a room on each side.

It also depends on what you need. A house for two requires far fewer walls than a family home.

The location would have to be truly spectacular to make this worthwhile. I would go crazy constantly running back and forth over 3m (10 feet). The resale value is also likely questionable. The money is gone and the outlook is bleak. Better keep searching.

It sounds like you don’t necessarily have to build or are not in a hurry to build.

There are creative options for sloped sites, but with a 4-meter (13 feet) building envelope width, there is not much room to shift levels significantly.
Or is the slope spread across the 60 meters (197 feet)?
In that case, you can, of course, stack volumes like building blocks in a staggered way, but this will result in roughly 325 cm (128 inches) of interior width, as others mentioned.
Certainly, some architects can make the impossible possible here—for example, by adding bay windows to widen the main room a bit, then accessing a narrower cube via a split-level design, all arranged like terraces. However, this kind of design is not cheap. If you still have family, it would be better to invest the money in a simpler plot.

Search the internet for the terms "Stuttgart narrow house"; there are some examples of narrow houses on slopes, although with reduced setback distances, allowing for an interior width of 4m (13 feet). In some cases, special facade claddings are used to maximize width. Everything is very individual and high-cost.

Thanks in advance for your opinions!

Yes, the location is quite good, so the development is definitely appealing.
However, we don’t have to build to live in it ourselves—of course, that is possible but not mandatory.
Potentially also an option to rent it out, which is why a smaller alternative with a large garden for enthusiasts is also being considered.
