Background
Gerdev Pty Ltd sought consent under s 4.55(8) of the Environmental Planning and Assessment Act 1979 (NSW) to modify an existing approval for a nine-storey shop-top housing development over four basement parking levels at 97 Gerrale Street, Cronulla. The site includes two locally listed heritage buildings and adjoins St Aloysius Catholic Primary School.
The proposed changes included revisions to glazing and privacy screens, balustrades, rooftop plant, planters, floor levels and the building’s upper-level design, as well as a new pool for a Level 8 residence. Sutherland Shire Council opposed the application on grounds including heritage impacts, height, floor-space ratio, aesthetics, public interest and deficiencies in the submitted material. The applicant filed extensively amended plans shortly before the hearing, which the Court permitted it to rely on while preserving the Council’s right to seek related costs.
The Court’s Holding
The Court upheld the appeal and granted consent to the modification application, but required further amendments before the revised plans could be approved by the Council. It accepted the modest height and floor-space-ratio increases, including a 335 mm rooftop-plant exceedance and extended residential lobbies, and found that the principal public-interest and documentation concerns could be addressed through conditions.
The Court rejected modifications that would undermine design features central to the approved development. Privacy screens and 1.6-metre-high obscure glazing must remain on specified school-facing and neighbouring elevations because their removal would materially alter the approved privacy and overlooking protections and would not produce substantially the same development. Solid components must be retained in specified Level 8 balustrades, and the north-east recess must remain open to the sky; the proposed pool and spa must therefore be relocated and resubmitted or deleted. The Court also required restricted access to the Level 4 planter area, consultation with the school about boundary works, structurally safe reinstatement of the heritage awning and rooftop screening consistent with the nominated architectural drawing.
Key Takeaways
- A modification may be approved only if its effects, not merely its physical changes, preserve the development’s essential identity as substantially the same development.
- Removing approved privacy screens and obscure glazing was unacceptable because those features were fundamental to protecting the adjoining school and residential property from overlooking.
- Minor height and floor-space-ratio increases may be acceptable when supported by practical design and engineering reasons and when they do not materially increase perceived bulk or scale.
Why It Matters
The decision illustrates the limits of using a modification application to revise design features that were integral to the original approval. Even where most amendments are acceptable, the Court may require retention of privacy, heritage and architectural measures that were important to resolving the original application’s impacts.
For developers and councils, the case also underscores the importance of assessing the visual and amenity effects of proposed changes in context, particularly where a prominent development affects heritage items, sensitive neighbours and long-distance public views.
