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 The DIN 18022 on bathroom planning appears to have been withdrawn without replacement.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?

It will be enough for a desk and a guest bed. The roof pitch is 35 degrees, and the room height in the middle is currently 2.30 m (7.5 ft). Is the ridge beam and floor structure already taken into account there?
Dormers are certainly nice; I stood in the attic with the newly erected roof frame and thought I would like one too. But each dormer costs a lot of money, and with each one, you get closer and closer to the basement. I know you have decided not to include a basement. But on the small plot, it would really be helpful, and if you are building without one for financial reasons, you shouldn’t spend that money again on the attic.
I believe this has already been taken into account. However, I will double-check. We are definitely not going to add a dormer costing €80,000. The basement is roughly in that price range, or even higher. Let’s wait for the quotes. I expect to receive feedback from the last two construction companies still in the running by the end of the week.

WilderSueden13 Dec 2022 22:28The dormer also provides less. You have to consider the whole package. We shouldn’t talk about building exactly the same house once with a basement and once on a slab foundation. Using the attic space here necessarily means having an upper floor without sloped ceilings. In other words, with a basement you can not only avoid the dormer but also save a few rows of bricks, along with plastering and so on, which adds up (I roughly estimate about €1500 per 10cm (5 inches) increase in knee wall height). Additionally, you save building height and setback area. This might cost about €40,000 more overall, but you get more space and greater flexibility.

On top of that comes a roof without a knee wall… roughly like yours. This is basically about the “expansion reserve” in the attic, which unfortunately is not as extensive given the house size as it is in your case.
The space in the attic only becomes usable as a room through the planned dormers.
Sometimes it’s really frustrating how limited and small one is allowed to build.
