More Than Extra Space

A Granny Flat Designed Around Your Property and the Way You Live

A well-designed granny flat should feel like a natural extension of your property—not an afterthought.

Whether you are creating a comfortable home for family, building an additional rental income stream or planning for greater flexibility in the years ahead, JYL Construction brings feasibility, approvals, design and construction together through one experienced team.

Before a floor plan is selected, we consider the conditions that shape what can realistically be approved and built—from block size, access and services to setbacks, orientation and the likely approval pathway.

  • Site-Led Planning

    We begin with the block, considering access, services, orientation, setbacks and the likely approval pathway.

  • Design Around Real Needs

    Layouts are considered around how the space will be used—by family, tenants, guests or as a flexible long-term asset.

  • One Coordinated Team

    Feasibility, design, approvals and construction are brought together through one experienced team.

Learn More About Getting Started

Can I Build One on My Property?

Start With the Site, Not the Floor Plan.

Every good granny flat begins with a clear understanding of the block. We look at the conditions that shape what can realistically be approved and built before you commit to a design.

What We Look At

  • Land size
  • Residential zoning
  • Property access
  • Existing services
  • Setbacks
  • Site conditions

Understand the Pathway

Choosing Between CDC and DA Approval

The likely pathway depends on the property, planning controls and proposed design. We help you understand the difference before you commit.

CDC Approval

Where a property and design qualify, CDC may provide a more direct approval pathway through a private certifier.

  • Assessed against complying-development standards
  • Suitable for qualifying sites and designs
  • Requires complete plans and supporting documentation

DA Approval

A Development Application is assessed by the local council and may provide greater design flexibility.

  • Suitable for more complex sites or proposals
  • May require additional reports or consultation
  • Generally involves a longer assessment pathway

Not Sure Which Pathway Applies?

We can review your property and explain the likely pathway, key documentation and next steps.
