The Housing SEPP’s Infill Housing provisions offer a clear opportunity to achieve planning uplift beyond existing Low-Medium Density Residential (LMR) controls in Castle Hill. These provisions support a broader range of housing types—such as manor houses and terraces—and allow flexibility in FSR and height where aligned with strategic planning outcomes. Given Castle Hill’s connectivity and Metro access, the site may warrant uplift through Clause 4.6 variations or a planning proposal. This pathway enables increased yield and development potential, provided proposals demonstrate design quality, infrastructure capacity, and consistency with local character and broader state planning objectives.
