Hello forum!
Our house construction is now in full swing. At the moment, we are waiting for the ground floor ceiling. The more we look at the drawings, the more doubts we have about the visual design of the roof. I find it particularly disturbing that the southern eaves appear so high when looking at the building from the west. Therefore, I am primarily considering whether we should enlarge the roof overhang.
Originally, we wanted a Friesengiebel, but this was not approved due to local conditions. So we changed our designs and sent a CAD drawing to the requested general contractors. The contractor of our choice essentially adopted the roof 1:1.
What I am wondering:
1. Is it "normal" for all sides of a half-hipped roof to have the same pitch? Are there reference values deviating from this?
2. Would a larger roof overhang mean that the static calculations have to be redone?
3. I would probably like the purlins to protrude. Are these at the same height as the wooden beam ceiling on the upper floor? Then the "gable eaves" would have to be higher.
4. What speaks in favor of a roof box, what are the disadvantages?
5. If we enlarge the roof overhang, do we then have to pay attention to the floor area ratio? We have fully utilized the floor area ratio of 0.4. Does the roof overhang count if it exceeds a certain size?
6. Are exposed rafters on the gable sides structurally relevant? Do they have to be present from a certain overhang onward?
7. Does anyone have a good tip?
Thanks and have a nice weekend :)
