Eyebrow porch roof and barrel vault ceiling

[Bob Dylan]

I already built this one once, and am working on a deal to build another copy of it. The fun part of the frameup was the porch part, shown in the attached pics and Sketchup file.

The top roof part has a 20' underside R., with 9' R. fillets. As can be seen in the model and photo, the underside is a plain barrel vault, and strip lighting in that step, does a knockout job of night lighting inside the room.

I did the model in Sketchup, as an exercise, having previously done the model in a higher-powered 3D CAD package.

All those curved rib parts are bandsawn from 2x sawn lumber stock, and the patterns are first plotted full-sized on paper using an engineering plotter, then stuck onto the stock using 3M spray adhesive. The plots are generated from the CAD files.

Here's the SU file. I only modeled the hard part, which is the porch and its roof. The rest of the house is all just cut and paste stuff.

Looks like fun stuff Bob. We never do anything like that around here ... I'm going to have to jump ship to find a challenge.
How about sloping the dormer ridgeline and having purlins intersect ("layover" style) the slope of a main roof?

Here it is with its hip corners and the array of lay-ons that go up and over the eyebrow with its fillets.

that's some nice crap there!

I'd be Slightly concerned on the R value, but I live in the polar north and that stuff crosses my mind often..
