Development Approvals: Navigating Sydney's approval processes for dual occupancy homes can be complex. Our tteam simplifies the journey, ensuring your duplex construction is seamless, and compliant. We will guide you towards obtaining either:

• • Development Application (DA) approval: This is the standard approval pathway for duplex developments that don't meet the criteria for Complying Development.
  • Complying Development Certificate (CDC) approval: This is a streamlined approval process for duplexes that meet specific size, design, and siting requirements outlined in the Complying Development Code.

Dual Income Potential: Generate renal income by living in one dwelling and leasing the other —an ideal solution for homeowners and investors in Sydney to help offset your mortgage or create a steady investment stream.

Maximize Your Land: Transform your block with two modern homes, perfect for growing families or those who are seeking additional living space

Investment Opportunity: Take advantage of Sydney’s booming property market with a duplex that offers long-term capital appreciation.

Cost-Effective Construction: Building two dwellings at once is more cost-effective than constructing separate homes, making duplexes a smart choice for Sydney homeowners.

While land size is important, other considerations like zoning, minimum lot requirements, and stormwater drainage must also be addressed. As expert duplex designers and builders in Sydney, we guide you through these complexities, helping you determine if a DA or CDC pathway is best suited for your project.

This depends on several factors. Generally, in Sydney, the minimum land size required to build a duplex home requires 400 square metres, or the minimum lot size that has been specified by the local council. You will also require a minimum width of 15 metres but can be as low as 12 metres if parking is provided at the rear or accessed by a secondary road such as a laneway.

Absolutely! At F.J.C Design & Construction, we offer flexible solutions tailored to your needs, whether you want a turnkey duplex design and construction service or you already have an architect and approved plans.

We have worked with Inner West Council, Canterbury-Bankstown Council, Georges River Council, Bayside Council, SUtherland Shire Council, Ku-ring-gai Council, Parramatta City Counbcil, The Hills Shire Council, Liverpool City Council and Fairfield City Council.
