When to Start Building in Perth

Planning to build your dream home in Perth? One of the most common questions we hear at Aveling Homes is: when’s the best time of year to start building? And it’s a great question, because timing can affect everything from site conditions to trade availability, costs, and even your overall experience.

Perth’s Building Seasons Explained

Perth’s climate is classified as Mediterranean, meaning we get hot, dry summers and mild, wetter winters. This seasonal pattern has a direct impact on how building work progresses.

Spring (September to November): A Popular Choice

Why it’s great:

Ideal weather – The ground is usually dry enough for earthworks, but temperatures are still comfortable for tradies.
Longer daylight hours – More time in the day means jobs can progress faster.
Time your move – Starting in spring may mean your home is ready just in time for the following winter or even sooner.

Things to consider:

Because it’s such a popular time to build, trades and suppliers can get booked out quickly. Early planning is key.

Summer (December to February): Fast Progress, But Hot

Why it’s great:

Dry weather – There’s little risk of weather delays due to rain, especially during earthworks, slab pour, and framing.
Efficient build stages – With minimal weather interruptions, things often move faster during the summer months.

Things to consider:

Extreme heat – Prolonged heatwaves can slow down some exterior work.
Christmas shutdowns – Most of the industry takes a break around late December to early January, which can pause progress for a few weeks.

Autumn (March to May): The Smart Season

Why it’s great:

Stable conditions – The weather tends to be predictable, with warm days and cooling nights, ideal for many construction stages.
Avoid peak demand – Autumn can be slightly less hectic than spring, making it easier to lock in trades and reduce wait times.

Things to consider:

If you start in late autumn, be prepared for some delays as winter weather rolls in, particularly if the site isn’t yet at lock-up.

Winter (June to August): Slower, But Still Doable

Why it’s great:

Potential trade availability – Some builders have more availability during winter, which can work in your favour.
Time to plan and select – You can use winter to finalise designs, approvals and selections, then hit the ground running in spring.

Things to consider:

Wet conditions – Rain and muddy sites can delay early works like excavation and concrete pours.
Longer timelines – Overall, expect progress to be a little slower than in drier months.

So, When Should You Start?

It depends on your personal timeline, financial goals, and how soon you want to move in. Here’s a simple way to decide:

Want the fastest start-to-finish build? Late summer to early autumn is often the sweet spot.
Need time to plan, save, or sell your current home? Start paperwork in winter and aim to build in spring.
Keen to beat the rush? Avoid peak times by starting in autumn or early winter, if you’re not in a hurry.

No matter the season, the most important factor is preparation. The sooner you get your land, finance, and selections sorted, the smoother the journey will be, regardless of the weather.
