What have you got on the western side of the house? It’s quite close to the boundary so you may find the western sun doesn’t actually get through the windows much (which would be good).
I wouldn’t worry about the Alfresco shading, you’ll get lots of light in.
I’d keep the Alfresco on the side it’s on so you have protection from western sun glare in the evenings and also from westerly winds. The front of our house faces west and the wind absolutely howls around our front door.
