Core Planning Reasoning

The proposed rear extension is out of scale and visually overbearing, detracting from the special character of the Protected Structure and seriously injuring the residential amenities of adjoining properties through overshadowing and visual intrusion.

Decision Maker's Conclusion

  • The development materially contravenes the 'Z2' land use zoning objective and fails to comply with heritage protection policies aimed at conserving Residential Neighbourhood Conservation Areas.
