Doubled cedar 2x12's extend beyond the south wall and bear on an external beam to create the main structure for the south canopy roof. This roof will provide a frame to attach vertical slats that will shade the southern sunlight entering the kitchen. It will also collect and distribute the water running down from the rest of the roof.

The canopy roof slopes up to stop the water from flowing off the end of the roof and directs it to a location where a roof drain will be located. This roof drain will collect the water into a cistern. Next to the roof drain is a large framed scupper that will allow heavy rains to overflow off the roof.

The roof drain will extend down to the bottom of the canopy beam. From there the water will fall visibly into the cistern below. This roof drain is centered on the kitchen window where the sink will be located, allowing a visible connection between the rain water and kitchen faucet water. This collected rain water will be used for watering the vegetable gardens to the south.

Here is the overflow scupper and the low area showing where the roof drain will be located.
