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 The DIN 18022 on bathroom planning appears to have been withdrawn without replacement.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

Here is an example of a construction project in Hamburg from two years ago. The house is now completed. On a plot similar in size to ours, they managed to maximize the living space quite cleverly. In particular, the two dormers transformed a narrow attic into a very usable room. Sunshine387 schrieb:
Visually, it’s not that impressive (in your picture), I couldn’t have put it more nicely ;-)
Günni now has to handle that awful example picture without any support like a Doornkaat *LOL*

A dormer doesn’t exactly cost a fortune, and with current construction prices, it’s definitely cheaper than a basement. Not every comparison holds up ;-)
Dormers rarely come alone. In practice, there are usually additional reinforcements because the structure spans several rafter bays, and that’s just the beginning of several layers of extra costs.

Bertram10013 Dec 2022 22:48I would much rather have a dormer than a basement. Regardless of the costs, the space created is far more appealing than a basement room. If you have doubts about dormers, take a look around the Netherlands. They have built such small houses in the cities that almost every house has a proper dormer. It looks decent to good and turns a small house into something genuinely usable. I would choose to add a dormer if it’s financially and technically possible, no matter how much a basement would cost.

A basement doesn’t provide any natural light either. And to make a room suitable for working there, large windows are necessary. Then quickly you end up with an expensive finished basement costing around 80,000. You’re overlooking the utility room moving out of the ground floor. All without a finished basement. A lower building height might also allow for an extra half meter or even a full meter of house height.
I basically have the same concept as the original poster, although with a 30-degree roof pitch. That’s why I asked if the 2.30 m (7 ft 7 in) height includes the purlin and floor structure. If you add another 30–40 cm (12–16 inches) for the purlin and 10–15 cm (4–6 inches) for the floor structure, the space is much less generous than the plan’s raw structural dimensions suggest.
I once considered extending the proper staircase all the way up to the attic instead of using a pull-down ladder. To make the height work, you would need a dormer. The general contractor quoted around 15,000 for that. If you make it a bit larger and maybe add two dormers…

You are overlooking the technical room being moved from the ground floor. Completely without a basement. Or, if the attic can still be considered “relatively spacious” here: one might consider relocating the technical room there, see:

It would also be possible to use the upper floor only for storage and allocate the utility room there – so non-habitable spaces, and therefore no complex fire escape requirements. We discussed this with @Golfi90 in https://www.hausbau-forum.de/threads/gedaemmten-technikraum-fuer-die-gastherme-auf-dem-dachboden-schaffe.32450/ https://www.instagram.com/11antgmxde/
