Willoughby Council Planning Guidelines

Residential planning and zoning rules

Willoughby Council residential regulations focused on:

Neighbourhood character and streetscape cohesion
Sensitive integration of new builds through form, scale, and materials
Two-storey height limits in most residential zones (varies by location and slope)
Regulation of Floor Space Ratio (FSR), setbacks, site coverage, and landscaping
Design guidance on roof pitch, eaves, articulation, and façade expression
Heritage controls in areas like Castlecrag’s Griffin Conservation Area
Environmental design mandates, including sustainability targets, WSUD, and urban cooling
Amenity preservation, including privacy, solar access, and acoustic comfort
Controlled allowance of dual occupancies and secondary dwellings (where zoning permits)

While these rules may appear restrictive, they are considered. The aim is to ensure that new development maintains a high standard of quality and does not impede the surrounding environment.

The positive and the challenges

Willoughby Council residential planning regulations provide a structure for functional and aesthetically pleasant residential buildings.

The positives

Contemporary design is welcome.
Council advocates sustainability and forward-thinking architecture.
Heritage areas allow modern interpretation.
Dual occupancies are permitted in some zones.

The challenges

Overshadowing and solar access requirements are tightly enforced.
Height, scale, and material controls.
Heritage precincts require detailed design.
Steep or narrow lots are complex due to privacy and outlook compliance.
Dual occupancies must demonstrate unity and minimal visual impact.

These challenges, when used as a design brief, are manageable.

“Contemporary design is welcome, provided it respects context.”

What does this all mean for land and homeowners?

Whether you’re planning an extension or a new build, Willoughby provides significant potential.

Opportunities include:

Split-level, layered homes that address slope, preserve privacy, and optimise light.
Sustainability-focused homes that exceed BASIX through passive design, solar, and WSUD.
Considered heritage upgrades that bring modern comfort to historically significant properties.
Dual-occupancy and multigenerational designs, with complementary facades or discreet rear studios.
Contextual landscaping, enhancing tree canopy, biodiversity, and microclimates.

Aligning the design with Willoughby Council’s residential planning regulations is non-negotiable. The council is committed to residential development that reflects the area’s character. This requires a comprehensive and strategic approach to architecture, materials, and landscaping.

“We ensure your home is something you’ll love to live in for years to come.”

Our architectural perspective

Playoust Churcher Architects has delivered dozens of successful projects across the Willoughby Council catchment. Our design approach, listed below, is brought together through our six-step process.

We integrate into the slope and solar conditions using stepped rooflines and clerestory glazing.
Our use of passive design, low-carbon materials and rainwater systems addresses sustainability.
We deploy screening materials and strategic placements to manage privacy, view concerns and overshadowing.

Leveraging our expertise helps homeowners and developers in the Willoughby council execute their design vision while staying compliant.

Frequently Asked Questions

How strict are Willoughby Council’s planning controls?

Willoughby Council’s detailed framework focuses on character, amenity, and sustainability. While they welcome contemporary and environmentally responsible design, any proposal must align with height limits, setbacks, heritage overlays, and neighbour impact guidelines.

Can I build a dual occupancy or granny flat on my property?

Dual occupancies and secondary dwellings are allowed in certain zones. However, they must demonstrate design unity with the primary residence, be visually subordinate, and maintain privacy and solar access for the property and neighbours.

What’s expected when designing in heritage areas like Castlecrag?

Properties in heritage zones must preserve original features and reflect surrounding rhythms. Willoughby Council supports modern interpretations over imitation, provided they respect nearby homes’ scale, materiality, and visual context.

How do environmental regulations impact my build?

You must meet or exceed BASIX and integrate Water Sensitive Urban Design (WSUD). The council encourages features like passive solar design, rainwater harvesting, green roofs, and low-impact materials that promote long-term livability.

What are common planning pitfalls in Willoughby?

Overshadowing, bulk scale, and overlooking neighbours are common reasons for DA refusal. Proper management of building height, privacy screens, and solar access is essential for gaining approval.
