Hello everyone,
after successfully applying for a building plot, I have now received the reservation confirmation.
Now the question arises regarding the planning of the single-family house.
In the textual regulations of the development plan, it states "The eaves height, measured from the top edge of the finished ground floor slab to the intersection of the outer edge of the rising external masonry with the roof covering, must not exceed 3.50 m (11 ft 6 in)."
Two full stories are permitted, and the maximum ridge height is 8.50 m (28 ft).
As for roof types, shed, gable, and hipped roofs are allowed. The permitted roof pitch ranges from 28° to 35°.
I would like to build a "city villa," which usually has an eaves height above 3.50 m (11 ft 6 in), since the first upper floor is typically built without a roof slope, and there are two full stories with a hip or pyramid roof.
Now to my question:
A pyramid roof is a type of hipped roof. Is your pyramid roof automatically approved if a hipped roof is allowed in the development plan? And does the eaves height restriction always apply, regardless of whether you build one or two stories? In a neighboring development area, the regulation states:
"The building height at the eaves side, measured from the top edge of the finished ground floor slab to the intersection of the outer edge of the rising external masonry with the roof covering, must be between 3.0 and 3.8 m (9 ft 10 in and 12 ft 6 in) in the area designated for single-story construction."
This sounds as if the eaves height restriction only applies to single-story buildings and not to two-story buildings?!
So, if the 3.50 m (11 ft 6 in) eaves height limit is fixed, the dream of a "city villa" would probably be over :-(
Thank you very much in advance for your help!

In a neighboring development area ... it’s not worth comparing, as a different development plan applies there.

So, if the 3.50 m (11.5 ft) eaves height were fixed Yes, it is fixed. But I didn’t realize there are sloped lots in Lower Saxony. A creative architect or some active members here might help design something villa-style with a basement. For that, you would need a site plan showing the exact measured property boundaries, building limits, and especially elevations, including planned road heights.

I agree regarding the roof shape Me too.

but I’m not sure Neither am I. Check with the local municipality to see how they interpret it.

if the geometry even matches It doesn’t necessarily have to. These are all maximum limits.

Because how am I supposed to reach an 8.50 m (27.9 ft) ridge height with a 3.50 m (11.5 ft) eaves height and max. 35° roof pitch A shed roof (monopitch roof) easily achieves that height.
Now it all makes sense.
It doesn’t require two full floors, only the maximum ridge height.
And with a site coverage ratio of 0.4, the outbuildings are included in the calculation, which also explains why a floor area ratio of 0.5 is reasonable and why the planning approval was set that way.
Hey, just write the name of the development plan in plain text instead of a link—something like "Posemuckel No. 815 in the meadows"—then we can look it up on Google.
By the way, non-experts often mix up (both visually and textually) information that applies to different building zones within the same development plan.
A tent roof is a hipped roof without a ridge, which typically occurs over a square footprint. But a small dummy ridge of half a meter (about 1.5 feet) in length is also possible, if the building authority insists on making a distinction. For a square plan measuring 10 x 10 m (33 x 33 feet) with a 28° roof pitch across, and a 30° pitch along, it would create a ridge about 80 cm (2.6 feet) long; the 2° pitch difference is barely noticeable, and the authorities are satisfied.
In my opinion, not being able to build a “city villa” in this case is usually not a significant loss—what is your motivation behind wanting to build one?

I had the exact same question about the ridge and eave heights—whether they actually fit together geometrically, or if it’s a contradiction (2 full stories, 3.50 m (11.5 feet) eave height, 8.5 m (28 feet) ridge height, shed, hip, and gable roofs with pitches between 28° and 35°).
