Attic studio at 9.00 m ridge height?

Hello everyone!

A few questions about a loft studio with a low ridge height:

1) Is it possible to have a 2.5-story gable roof semi-detached house (house length 10-11 meters, eaves height max. 6.50 m) with a loft studio at a maximum ridge height of 9.00 m? Or should one rather plan a 2-story house without a loft studio?

2) Is a dormer or a transverse dormer feasible at this ridge height?

3) Would anyone possibly have a cross-section of such a house? (See attachment)

Best regards

Peter

Hello Peter,

A few questions about a roof studio with a low ridge height:

I wouldn't call a ridge height of 9.00 m low...

1) Is it possible to have a 2.5-story gable roof semi-detached house (house length 10-11 meters, eave height max. 6.50 m) with a roof studio at a maximum ridge height of 9.00 m? Or should one rather plan a 2-story house without a roof studio?

In advance - according to building law, there is no 2.5-story construction method, but only I-, II- or multi-story.

Your question cannot be definitively answered because the reference point for measuring the eave height is missing. Is it measured from the top edge of the finished floor or from the existing ground? Roughly, you can see from the section you attached that a usable attic is likely to result. But it also depends on the roof pitch.

2) Is a dormer or a cross gable feasible with this ridge height?

That primarily depends not on the eave or ridge height, but on the development plan.

Rhenish regards

Thank you for the answer, Bauexperte!

For a semi-detached house, I find a ridge height of 9.00 m already quite low.

The reference point is the middle of the street in the middle of the property.

A dormer is probably not possible because the ridge of the dormer must be at least 50 cm lower than the ridge of the house roof, and the dormer will also have a roof with a pitch of at least 10 degrees, so the dormer roof would be too low.

For a house 10 m x 7.50 m, I come to a roof pitch of 26.5°. With 1.40 m high knee walls, I get a roof studio that can be divided into 2 rooms of 15 sqm each.

Let's see what the construction company says, whether my calculations are somewhat correct.

Regards

Peter
