Two concept designs have been developed -
1. Single carriageway: a single road with 1 lane in each direction; this layout allows larger lawn areas in front of properties and costs less to construct than a divided carriageway.
2. Divided carriageway: two roads separated by a grassed median strip. While a divided residential street offers benefits such as improved safety and aesthetics, it generally costs more due to greater land use, increased material requirements, more drainage infrastructure, additional utilities, and higher labour costs compared to a single carriageway.
