Hello, Iam looking to build a two storey house in Ryde area and the land has a 4m drop from front to rear backyard fence. Have anyone built with Ryde council before? Could someone recommend builder who will build on sloping block? Would anyone share there experience and costs when building on a sloping block? What important design elements should i specifically look out for that can be detrimental to the completed house if i don't get it right at the drawing stage? Love to hear your comments and ideas.
