A house that works in Perth starts with the site it sits on. Coastal blocks, narrow infill lots, sandy soils and steep hillside sites all behave differently, and the design that suits one rarely suits another. This guide covers the decisions that shape a Perth home before a single drawing is done.
Start with the site, not the style
Most people arrive with a folder of inspiration images. They are useful, but they come second. Before style, we look at:
- Orientation. Which way does the block face, and where does the winter sun actually land in the middle of the day?
- Levels. Is the block flat, gently sloping, or steep enough that retaining will dominate the build?
- Access. Where does the driveway go, and can a truck and a crane reach the site?
- Neighbours. Overlooking, overshadowing and privacy all shape where rooms can go.
Getting these answers right early is what keeps a project straightforward later.
Designing for the Perth climate
Perth runs hot, dry summers and mild, wet winters. Good design here is less about gadgets and more about the building’s bones:
- Living areas that catch northern winter sun and are shaded through summer.
- Cross ventilation that lets the afternoon sea breeze move air through the house.
- Deep eaves, verandahs and pergolas that shade glass before the sun reaches it.
- Insulation, airtightness and glazing chosen as a system, not as single upgrades.
Homes we design are modelled in NatHERS compliance software, so energy performance is measured during design rather than assumed after the fact-or at the end of the build.
The shape of your block
Perth has more variety in block shape than most cities. Narrow infill lots reward a plan that runs long and lean, with rooms borrowing light and outlook from courtyards. Sloping sites often suit a split level approach that follows the ground rather than fighting it. Corner blocks bring extra frontage, and extra constraints with it.
The rule of thumb: work with the ground you have, and you spend less on earthworks, retaining and drainage.
Planning and approvals
Most residential work in Perth needs some form of approval. Renovations and additions usually begin with a planning assessment against the R-Codes and your local council’s scheme, followed by a building permit application. Character and heritage areas add a further layer, and can affect everything from roof pitch to the front fence.
We handle the approval pathway as part of the design work, so you are not left negotiating it alone.
Sustainability that pays you back
Sustainability in a Perth home is rarely a single feature. It is the accumulation of orientation, shading, insulation, efficient fittings and appliances, water-wise landscaping, and a plan that is the right size for how you actually live.
A smaller, better-organised home costs less to build, less to cool and less to maintain. That is usually the most sustainable move available.
Working with an architect
An architect brings three things to a house project: a design that responds to your site, documentation that a builder can price accurately and build from, and someone in your corner through the approvals and construction phases.
We are a practice working across the Perth metro area and regional Western Australia, on projects of a practical scale and budget. If you are planning a new home in Perth, a conversation early — before you buy, or before you commit to a plan — is usually the cheapest advice you will get.
Where to start
Bring a few things to that first conversation:
- Your realistic budget, including site works and fees.
- Any survey or title information you already hold.
- A short list of what your current home does and does not do well.
That is enough for us to tell you what is achievable on your block, and what it will take to get there.
