Planning Permissions & Regulations for Two Story House Designs in WA

September 25, 2025

Building your dream home is an exciting journey, especially if you’re considering two story house designs. In Western Australia (WA), these designs have become a popular choice for families and individuals who want to maximize their block size, enjoy modern layouts, and add long-term value to their property. However, before construction begins, it’s essential to understand the planning permissions and regulations that apply to two storey homes.

This guide will walk you through the key aspects of planning, council approvals, and design considerations so you can make informed decisions.

Why Choose Two Story House Designs in WA?

Opting for two story house designs offers multiple advantages. They allow homeowners to enjoy more living space without compromising outdoor areas like gardens or backyards. With WA’s growing preference for smaller urban lots, double storey builds provide the perfect solution for families who want spacious, functional homes on compact blocks.

Some additional benefits include:

  • Enhanced street appeal with modern architectural styles.
  • Better separation of living and sleeping zones.
  • Opportunities for balconies, upper-level views, and natural light.
  • Increased property value in competitive markets.

Understanding WA Building Regulations

Before you begin your two storey house design, it’s important to comply with WA’s Residential Design Codes (R-Codes). These codes outline the standards for residential developments and ensure that homes align with local council requirements. Key considerations include:

  • Setbacks – Distance from boundaries, ensuring privacy and adequate light.
  • Building height – Restrictions may apply depending on the area.
  • Overlooking and privacy – Protecting neighbours’ privacy with window placement or screening.
  • Open space requirements – Ensuring a balance between built-up area and outdoor space.

Working with an experienced builder like Distinguished Homes can make the process smoother, as they are familiar with these regulations and can help navigate approvals.

The Approval Process for Two Storey Homes

When planning your two story house design, you’ll need to follow a specific approval process:

  1. Initial Consultation – Work with your builder or designer to finalise concept plans.
  2. Council Submission – Your application, including plans, is submitted to your local council.
  3. Assessment Against R-Codes – The council checks compliance with WA’s building codes.
  4. Neighbour Consultation – In some cases, neighbouring property owners may be notified.
  5. Approval & Building Permit – Once approved, you can apply for a building permit to commence construction.

This process ensures your design not only meets regulations but also maintains harmony within the neighbourhood.

Design Considerations for Two Storey Homes

When exploring two story house designs, functionality and lifestyle should guide your choices. Some key design elements to consider include:

  • Ground Floor vs. Upper Floor Usage – Many WA homeowners prefer living and entertaining spaces downstairs, with bedrooms and private areas upstairs.
  • Maximising Natural Light – Large windows, skylights, and open layouts enhance energy efficiency and comfort.
  • Outdoor Integration – Alfresco areas and courtyards complement two-storey layouts beautifully.
  • Future-Proofing – Consider flexible spaces that can adapt as your family’s needs change.

Selecting the right builder is crucial for turning your vision into reality. Look for professionals who specialise in two story house designs in WA, as they understand both the creative and regulatory aspects.

Key things to look for in a builder:

  • Strong portfolio of completed two-storey homes.
  • Transparent communication and cost breakdowns.
  • Knowledge of WA’s unique building codes and approvals.
  • Commitment to quality craftsmanship and design innovation.

Common Challenges with Two Storey Homes

While two storey house designs offer many advantages, there can be challenges if not planned properly. These include:

  • Extended approval times if your design requires variations.
  • Additional structural requirements for upper floors.
  • Higher costs compared to single-storey builds.
  • Limited access during construction on smaller blocks.

With professional guidance, however, these challenges can be managed effectively.

Conclusion

Building your dream home in WA with a two story house design is both exciting and rewarding. While the approval process and regulations may seem daunting, working with the right team ensures everything runs smoothly.
