Multi Development

Maximise Your Land’s Potential with Smart, Efficient Designs

If you’re planning a multi-unit development, whether it’s a duplex, triplex, or a larger subdivision, having the right design and approvals in place is critical. At Patrick De Rossi Design & Drafting, we specialise in practical, council-compliant multi-unit designs that maximise your site’s potential while ensuring a smooth approval and construction process.

What Types of Multi-Developments Do We Design?

Grouped & Multiple Dwellings

Scalable solutions for high-yield developments.


Grouped and multiple dwelling developments require careful planning to maximise density, liveability, and compliance with R-Codes. We specialise in designing functional, high-quality residential projects that make the most of available land while maintaining privacy, natural light, and efficient traffic flow. Whether it’s a small cluster of units or a larger residential development, our focus is on streamlining approvals, optimising layouts, and delivering cost-effective, market-ready designs.

Battle-Axe & Rear Strata Developments

Smart solutions for tricky blocks and tight spaces.


Developing a rear strata or battle-axe lot comes with its own set of challenges, from access and setbacks to privacy concerns. Our designs ensure efficient land use while maintaining practical driveways, parking solutions, and private outdoor areas. We work within site constraints to create functional, liveable homes that meet both council regulations and market expectations.

Townhouses & Villas

Modern, stylish, and practical multi-unit housing solutions.


Townhouses and villas offer a great middle ground between apartments and standalone homes, making them highly desirable for buyers and investors. We design efficient, space-conscious layouts that enhance street appeal while ensuring functional, well-zoned interiors. Whether it's a single-story villa or a multi-level townhouse, our designs integrate smart floor plans, private outdoor areas, and quality finishes to create market-friendly homes.

Duplex & Triplex Developments

Maximise your land’s potential with efficient, council-approved designs.


Duplex and triplex developments are a smart way to increase property value and generate strong rental returns while staying within local zoning limits. Whether you’re subdividing an existing block or starting from scratch, we create functional, well-planned designs that balance density with liveability. Our focus is on cost-effective layouts, smart use of space, and compliance with R-Codes to ensure a smooth approval process.



Small-Scale Apartments

Maximise density while maintaining liveability and design quality.


For developers looking to build low-rise apartment complexes, we provide strategic, regulation-compliant designs that meet market demands. Our approach ensures optimised unit layouts, shared spaces, and efficient use of the land, all while keeping costs under control and maintaining aesthetic appeal. Whether it’s a boutique apartment block or a mixed-use residential building, we focus on maximising investment returns while delivering practical, attractive living spaces.

Tailored Design Solutions for Developers & Investors

Every development is unique, and getting the best yield from your land requires careful planning. We create designs that:

  • Maximise land use efficiency while      maintaining functionality.


  • Meet local council zoning (R-Codes) and planning regulations to avoid delays.


  • Balance density and liveability for a market-friendly, profitable outcome.


  • Integrate cost-effective construction methods to keep budgets in check.

FAQs

  • How long does it take to complete construction drawings?

    The timeframe depends on the size and complexity of the project. A standard residential home typically takes 1-3 weeks, while larger or more detailed projects may take longer.

  • Can I make changes after the drawings are completed?

    Yes, but changes after finalisation may require revisions, which can affect approvals and construction timelines. It’s best to finalise all design decisions before completing the drawings to avoid delays.

  • Do I need construction drawings for a renovation or extension?

    Yes. Even if it’s a minor renovation, detailed plans ensure the work is done correctly, meets council requirements, and avoids costly surprises during construction.

  • Can you modify an existing set of drawings?

    If you already have plans but need modifications, we can revise them to ensure they meet your new requirements, comply with regulations, and are builder-friendly.

  • Will these drawings be enough for council approval?

    In most cases, yes. However, depending on your project, you may also need engineering reports, energy efficiency assessments, or additional compliance documents. We can guide you through this process.

  • Can my builder work directly from these drawings?

    Absolutely. Our construction drawings are detailed and builder-friendly, ensuring smooth communication between you, your builder, and other trades.

  • What’s the difference between concept drawings and construction drawings?

    Concept drawings are preliminary sketches that explore the design and layout of your project.

  • Do you provide structural engineering drawings as well?

    No, but we can coordinate with structural engineers to ensure your drawings are fully compliant. If your project requires engineering, we’ll advise you on the next steps.

  • What format do I receive the final drawings in?

    You will receive the final construction drawings in PDF format (ready for council submission and builder use). If required, we can also provide DWG files for engineers and consultants.

  • How do I get started?

    Simple—get in touch with us! We’ll discuss your project, gather any necessary details, and outline the next steps to get your construction drawings completed efficiently.
