ᐅ Planning a gable roof and roof slope

Hello everyone,

I have a question regarding a gable roof and roof slope: My goal for my future house is to make the upper floor (first floor) as usable as possible in terms of floor area, while still showing the roof slope, without creating an attic space, and keeping the roofing economical. Is that even feasible?

My idea was: a high knee wall and a shallow roof pitch. This would make the center area (about 10m (33 feet) wide) quite tall.
--> How shallow can a gable roof be while still allowing for proper and economical roofing?
--> How tall can the rooms in the center of the house be while still maintaining good aesthetics?

Best regards and many thanks

Why not, you are right on trend with that idea.

That is not up to you but depends on the requirements of the local development plan/planning conditions for your plot. What do they specify regarding the roof pitch? And if you are allowed to build according to § 34, what is the character of the surrounding buildings?

That does not really matter in the attic but depends more on the intended furnishings.

Kind regards

As the building expert has already pointed out, the zoning plan or the surrounding buildings are decisive. For several reasons, two full storeys have now become standard. It is also worthwhile to evaluate the building permit / planning permission not only from an architectural (construction) perspective but also in the broader context from the viewpoint of building services engineering. One of the most economical solutions at present is the combination of heat pump and photovoltaic system. In the latter case, the roof area plays a major role.

Try drawing a cross-section with all the heights; that helps.

Hi,
first of all, thanks for the feedback.
There is no zoning plan for our plot, and the immediate neighbors have a variety of different houses... so standard constructions should be possible.

@ €uro: Why have two full stories become the preferred option? Could you please provide an example or explanation?
A photovoltaic system probably doesn’t make sense for us, as we get no sunlight on the property for several weeks in winter. Isn’t that when you need it the most?

I also drew a cross-section of the roof and considered several options... this one seems to make the most sense for me. Is this feasible and practical (roof pitch 21°)?

Best regards, Peter

It is certainly feasible, but whether it is practical depends on your needs. (--> floor plan)
