We have a large north-east facing (about 35 degrees east of north) street frontage and are custom designing a home in the Hills District - Two storey home and about six rectangular windows each on the ground floor and the first floor facing the street.
Likely we will go with a custom builder - I am trying to understand the implications of choosing 900mm eaves instead of 600mm or something smaller. Intent is for the eaves to provide summer shading from mid-November to mid-March. We would like to maintain a roof pitch of atleast 22 to 25 degrees (lots of solar PV and solar hot water).
Has anyone recently done this with a builder in the Sydney area? What are the cost implications? Can we get a higher roof pitch and the 900mm eaves (future expansion area in the attic)?
(Our designer is suggesting we keep to 600mm eaves)
