With some normal delay due to church officials' availability, here's the latest version overlaid on the bell location. Not exactly to scale, but close.
To reduce the roof load, my son sourced some lightweight plastic "Spanish tiles" to match the tiles in the building behind. He meets with the church officials this weekend to get their approval. I'm hoping they go with redwood. While it's twice the cost, it should last longer.
If it's a go, we'll have some busy weekends ahead.
