Roof Vignette 4.0

Postby KenArquitech » Tue Apr 10, 2018 7:29 pm

Hi all,

For the roof over the exhibition room I used the highest spot elevation from the lower roof then added my 24" (clerestory) + 18" (roof structure) to generate the spot elevation on the Southwest corner of the top roof. I feel there is a far better logic. Is the general rule of thumb to not let the bottom side of the top roof go lower than the top surface of the bottom roof?

Hindsight I suppose my upper roof could be lower in this iteration. Suggestions welcome.

Thanks -

That's incorrect. Use highest low roof point at clerestory wall -- Unless there's a reason to make it higher, like making sure upper roof is always above lower.

I feel there is a far better logic.

For what?

Use symmetrical gables.

Use symmetrical gables.

Upper and lower gutters on east side must be drawn independently and not share downspout.
