Skylight cutout

Why have a skylight in an outdoor porch roof?

Well, it's all about solar orientation and the needs of nearby rooms. I have an existing bedroom (possible future office or dining room) window just below it. The sun hardly shines in there, even with the previous short eaves. Now with the skylight, it's much brighter. Yet the deep roof shields midday sun nicely, providing a large protected walk-up area.

The framing stage at this point still allows changes. It can be closed off or cut larger. I think it's just right.
