Davistown Investment Build – The Coastal Design Within BAL29 & Flood Controls

Some sites look simple at first glance.

Flat block. Corner position. Great access.

But overlays tell a different story.

This Davistown property sits within both a BAL29 bushfire zone and a designated flood zone, requiring a full Council DA approval rather than a CDC pathway. For many investors, that combination can feel uncertain.

The brief was clear, deliver a compliant, modern coastal granny flat built for long term rental performance.

Compliance First – Designed For The Site

Due to the BAL29 rating, an increased rear setback of 12 metres was incorporated into the design. Fortunately, the depth and size of the block allowed this without compromising layout and the result was an added benefit, a generous backyard that enhances tenant appeal.

Because of the flood zoning, the granny flat was constructed on bearers and joists, ensuring compliance with flood planning controls while maintaining structural integrity.

Importantly, even with these overlays and planning requirements, the dwelling was built using our standard “The Coastal” floor plan with no amendments to the internal layout. The compliance considerations were resolved through positioning and construction methodology, not by compromising the functionality of the design.

Site Advantage – Access & Efficiency

While compliance required careful planning, the physical block itself worked in our favour. Being a flat corner site, access for trades and deliveries was straightforward, allowing construction to move efficiently from start to finish.

Good access combined with clear approvals creates momentum on site and momentum protects timelines.

Coastal Aesthetic – Built For The Market

As an investment property in a coastal pocket of the Central Coast, presentation was just as important as compliance. The owners selected a skillion roof profile rather than a traditional hip and valley, reinforcing the clean modern coastal aesthetic that suits the area.

The result is a dwelling that feels contemporary and well considered, while quietly meeting the demands of bushfire and flood regulations behind the scenes.

The Investment Outcome

What began as a site defined by overlays and setback requirements is now a compliant, modern coastal granny flat positioned for strong long term performance.

The 12 metre setback created additional yard space. The elevated floor system satisfied flood controls. The BAL29 requirements were integrated seamlessly into the approval process and the proven Coastal floor plan delivered the layout tenants expect.

For investors, zoning constraints are not obstacles. They are simply variables that need to be addressed early and structured properly.

With the right planning and the right pathway, regulated land can still become a high performing asset.

At Coastwide Granny Flats, compliance and design are never treated separately. They are solved together from day one.
