ᐅ Planning a Guest Bathroom in a New Build – What Is the Minimum Size? (Building Standards?)

Hello house building forum,
we are currently planning a semi-detached house. The building plot is very small, and the footprint is accordingly limited. To achieve a reasonably usable living area, we want to keep non-living spaces small and allocate the saved space to the living rooms.
On the ground floor, we are planning a guest toilet without a shower—that is, only a toilet and a washbasin. Recently, I have been carrying a laser measuring device when visiting friends and have measured several guest toilets. Conclusion: 1 meter (3.3 feet) in width and 2 meters (6.6 feet) in length are more than sufficient. In our case, the door would be on the short wall, the toilet opposite the door, and the washbasin on the long wall.
We are currently looking for a builder and have roughly presented our plans. One potential builder mentioned that according to the DIN standard, a guest toilet must be at least 1.24 meters (4 feet) wide.
My online research so far hasn’t been enough to find the relevant regulation or DIN. The DIN 18022 on bathroom planning appears to have been withdrawn without replacement.
Is anyone familiar with this requirement? Is it not allowed to plan a 1 meter (3.3 feet) wide guest toilet in a new build?

House dimensions per semi-detached unit: 8.50 x 7.61 m (28 x 25 feet)
Maximum height approx. 8.68 m (28.5 feet) …and with the roof pitch, the maximum height is reached.
You mentioned about 33 degrees…

The attic will be used as an office and guest room. Have you already considered the layout of the attic space? Although I seem to have misplaced my set square, the usable standing area width there should be about 2 meters (6.5 feet) at most.
It will be sufficient for a desk and a guest bed. The roof pitch is currently 35 degrees, with a ceiling height of 2.30 m (7 ft 7 in) in the center. We would have liked to go higher with the ridge, but then the setback area would interfere.
The best combination of house width and ridge height is still being worked out. Increasing one reduces the other.
The dormer is still under discussion, to gain some additional living space from what is already a fairly usable floor area.

The dormer is still under discussion to gain a bit more living space from the otherwise quite usable floor area. You probably mean the house depth, and dormers are top space maximizers; this applies even more to “dormers” as laypeople call them, which usually refers to gable dormers.

No dormer is cheaper than just a dormer, obviously. And if we had plenty of living space, you would definitely skip it. But let’s play through the scenario for now. I agree with you about cross-gable roofs; I wouldn’t need those either.
Here is an example from a construction project in Hamburg two years ago. The house is completed by now. On a similar footprint to ours, they cleverly maximized the living space. Especially the two dormers turned a narrow attic into a very usable room.
Our design won’t be quite that dormer-heavy. But it can definitely serve as inspiration for our situation.
