18' diam. Gazebo questions


In my backyard there is a large concrete slap in a quasi triangle design. In the center is an 18ft diameter dirt patch that the previous owner used to use to place an outdoor pool. I would like to build a gazebo on this dirt patch.
I like my neighbors to the Southwest and the gazebo would block their view to mountains at the Northeast, so I was thinking of sinking the dirt patch down 1.5ft and building the gazebo with a low pitch. About 15deg pitch.

I've contacted the city about building codes and I don't need any engineer sign-off. They only need a design of the roof materials and how I plan to anchor the gazebo.

My plan is a hexagonal design to fit into the circle with half-rafters used for the roof. The posts would be ~9ft apart and the roof pitch would be about 15deg. 9ft span, 2.5 ft rise. Is this pitch ok if I use half rafters? Do I need posts larger than 4"x4" treated lumber? Would I need to half joists spanning all the way across the diameter of the roof, or are the rafters enough?

The roof will be wooden rafters, 3/4" plywood and spanish tiles ontop. I plan on hanging maybe some lights and an exterior fan.

I live in Albuquerque, NM. Rainfall is minimal, but winds can be rough. We can get 70mph gusts on occasion in March-May.

I plan to anchor the posts into the ground with sunken concrete posts much like a deck.

I'm feeling dumb. What's a "half-rafter"?

Scope this weblink. The topview of the gazebo shows a half rafter layout for the roof.

If you say so.....

I saw a pergola type roof. Is that what you mean?

But I can't see how that would help your neighbor's view of the mountains.

A gazebo can look dumb with too low of a pitch.
And you do need ceiling joists to hold it together.

First I heard of half rafters also.

If you want to make it lower make it a step or two down.

Half-rafters are just rafters that go to a head-out so you don't have to cut those rafters at ridiculous compounds and then try to nail that cluster**** of rafters coming together at the peak.
And the head-outs almost kind of serve as collar ties, but I would still have joists in it.
(One octagon gazebo I built I hung a 300 Lb church bell from the peak).

From your description it sounds like you want to sink the floor down. There could be water issues with this.

I am already planning on sinking the gazebo down 1.5 feet, for asthetic reasons also. The backyard is excavated 4-5 feet above ground and the yard plot where the gazebo would be is next to an arroyo and the service road, so a simple channel off the side will drain easily into the arroyo. I'm not worried about the water.

I could sink it lower, but then I'd have to tear out concrete and make additional steps down so that tall people (i.e. me) don't smack our heads every time we go down to it.
