Duplexes: Say Hi to the Innovative Modern Dual Living Home Designs!
Are you looking for a living arrangement that lets you stay close to your extended family while still enjoying the benefit of privacy offered by a separate dwelling? Well, a duplex house design can be an ideal fit for you. This unique housing style consists of two living units built on a single block of land and separated by a central wall.
Moreover, a duplex not only bonds families together; it’s also a lucrative investment opportunity for real estate investors. This type of living arrangement is best for fostering connections. For example, if you have adult children or elder relatives, a duplex allows you to stay close to them while living in a separate home.

Parents seek a home away from home for their little ones — that’s what we help you build for them. As a daycare provider, it’s essential to create a warm, inviting, and home-like environment for children to play, explore and thrive. Our seasoned designers possess decades of experience in creating spaces that promote indoor and outdoor activities and contact between children and caregivers. We collaborate with you to develop daycare structures that incorporate bright, airy, spacious interiors and playful outdoors that parents trust their children to be in. We at Fyffe Design take time to study your requirements, emerging trends, and government regulations to craft designs that resonate with children’s needs. We are dedicated to crafting spaces that encourage exploration, creativity, and imagination, where children can thrive in a safe and welcoming environment.

More blocks are eligible now than before the recent NSW planning reforms, but it depends on your zoning, lot size, frontage and local controls. That is exactly what we review in your free feasibility session.
The 2026 Budget reforms limit negative gearing for residential property to new builds from 1 July 2027, and the government’s published examples describe a duplex replacing a single house as adding to housing supply. How the rules apply to your project depends on your circumstances and how the project is structured, so speak with your accountant before making decisions. Our role is the design and approvals side.
CDC (Complying Development) is generally faster where a project meets the criteria. If it does not, a DA through council is the pathway. We are experienced in both and will recommend the route suited to your block.
Many of our clients design with exactly that in mind. We shape the design around your intended use, whether that is dual rentals, live-in-one, or a future subdivision, and flag the approval and title questions to raise with your surveyor and solicitor.
No. Our focus is getting your design and approvals sorted first. Once your plans are ready, we can recommend trusted builders from our network, professionals we have worked with over the years who share our commitment to quality and clear communication.
It varies based on your design scope and approval pathway, but projects suited to CDC can move quickly. We will give you a realistic timeline during your feasibility session.
With over 3,000 homes designed, Fyffe brings deep experience, council knowledge and design clarity to every project. You work one-on-one with a senior designer and receive a plan tailored to your lifestyle, block and vision, not a generic template.
