Do I need council approval for a granny flat on the Northern Beaches?

AGATHĒ designs granny flats that are suitable for the premium Northern Beaches rental market, with quality finishes and coastal-appropriate materials that attract long-term tenants.

What makes AGATHĒ different from other granny flat builders?

AGATHĒ brings the same level of craftsmanship, attention to detail, and quality standards to granny flats as we do to luxury home renovations and extensions. We specialise in Northern Beaches properties, understand local planning requirements, and design for coastal conditions including sea air, strong sun, and maximising natural ventilation and light.

How much does a granny flat cost on the Northern Beaches?

Granny flat costs vary based on size, design complexity, site conditions, and finish selections. AGATHĒ provides transparent, detailed cost estimates during the pre-construction phase. We work with you to design a granny flat that meets your budget while maintaining our commitment to quality, longevity, and craftsmanship.

Can AGATHĒ build on sloping or challenging Northern Beaches sites?
