ᐅ Single-family house with 1.5 stories, maximum ridge height of 8 meters, and a gable roof possible?

Hello community,

I am interested in a plot of land that, according to the development plan, has specific requirements regarding building height and roof types.

Here are some details from the development plan:

• Two stories allowed
• Maximum ridge height of 8 meters (26 feet) measured from the center of the building to the nearest reference height point – the area is relatively flat.
• Only hip roofs or gable roofs permitted
• Roof pitch between 18° and 45°

My ideal plan is a 1.5-story house (no basement) with a gable roof and 150 square meters (1,615 square feet) of living space.

To what extent does the maximum height of 8 meters (26 feet) restrict my plan? Would a hip roof work better with this lower height, or is it mainly a matter of the knee wall height and my desired ceiling height? Regarding the latter, I am aiming for 2.60 meters (8.5 feet) ceiling height.

Thank you very much,
Anton

Well then, let's do some calculations: a floor area of around 120 square meters, for example, 11 meters (36 feet) building depth, with an 18° pitch roof at 1.80 meters (5 feet 11 inches) ridge height, would leave 2.60 meters (8 feet 6 inches) eave height, which seems feasible. The critical point here is your reference height (for example, the nearest manhole cover), and your perception of the ground level might not be entirely accurate. But since you are open to a one-and-a-half-story design, it wouldn’t be a big problem if it might not quite work out for a "town villa" style after all.

No, a hip roof doesn’t offer any real advantages (except for photovoltaics, if the alternative would be only two sloped roof surfaces with poor orientation).

That works fine with a gable roof house, as commonly known. Here, the height limit for a single-story building is 7.80 meters (25.6 feet)… just for comparison. I might be wrong, but with a knee wall height of 130 cm (51 inches) and a roof pitch of 26 degrees, that’s what we have. There are many Viebrockhaus Maxime 300 houses around me.

In principle, you have a lot of options, but a converted attic won’t be possible.

That’s not entirely correct. A hip roof can help in certain situations involving setback requirements. In our case, it was the only solution to allow two full stories; neither a gable roof, shed roof, nor a flat roof (with a small parapet) would have worked.

Then show us the site plan of the plot. It would be best if you also draw your desired house on it. A rectangular floor plan is helpful when dealing with limited building height.

Correct. What is meant is that the height of the wall is a factor in the setback area. Simply put, the wall height ends at the eaves with a hip roof, whereas with a gable roof you also have to consider the gable triangle. A rectangular floor plan without any projections or recesses makes it easier to determine the relevant points.
