I'd like to build an extension to the garage for additional entertianment.

I would too... but they are expensive and I'd need a building permit and a variance from zoning. What is your question?

You can try this freestanding awning (http://www.epatioumbrellas.com/shades_awnings/Freestanding_SunSetter_Oasis_Awning.html). If you want a cheaper alternative, you can also try a patio umbrella. There are several types you can choose, try to look at different types of patio umbrellas here (http://www.epatioumbrellas.com/).

I hope this helps.

Nee more info on intent, but smoothy is right about building permit.

Is there a patio there now?

How large of an area?

What type of awning?
