Build Your Winter Garden: Instructions, Tips & Ideas!

Aug 4, 2026

An alfresco or covered outdoor living space is a long-awaited dream for many Australian homeowners. Whether it's sheltering from a summer downpour in Brisbane, entertaining through a cool Melbourne evening, or creating a shaded retreat from the Western Australian heat — a well-built alfresco transforms the way you live outdoors, year-round.

If you want to create your own, this guide covers what to pay attention to, how to plan it properly, and how to make your DIY project a complete success. You'll also find practical tips and ideas to ensure that your new favourite space turns out exactly as you imagined.

Why Build an Alfresco Yourself?

You don't have to be a professional tradie to build a covered outdoor space. If you have solid DIY skills and are well-prepared, you can take on a large portion of the work yourself.

That said, get qualified help the moment you become unsure — particularly for structural elements, footing design, or any electrical work. It protects your safety and ensures the longevity of your structure.

The advantages at a glance:

Cost savings: Building it yourself instead of hiring a builder significantly reduces your expenses.
Individual design: You have full control over the design and finishes, and you can bring your personal style to every decision.
Year-round usability: A quality covered alfresco adds a light-filled, weather-protected space to your home that you can genuinely use in every season.
Property value: A well-built outdoor living area increases the long-term value of your property — it's consistently one of the most sought-after features for Australian buyers.

Planning and Preparation

When building your alfresco, detailed planning is the key to success. This includes design and materials, but also legal requirements. Getting both right means you'll enjoy your new space without any surprises down the track.

1. Open or Enclosed Alfresco?

Fully enclosed alfresco: Can be used year-round in all weather, and works particularly well for cooler climates in Victoria, Tasmania, the ACT, and highland NSW. Requires consideration of ventilation and, in some cases, heating.
Open or semi-open pergola: The most popular choice across Australia. Provides shade and rain protection while keeping the space open and breezy — ideal for Queensland, coastal NSW, WA, and SA.

You can also start with an open structure and enclose it later. All Pergolux accessories — including zip screens and glass walls — are designed to be added at any time via the SnapFIT™ system, with no drilling into the frame required.

2. Permits and Council Regulations

Whether you need council approval depends on your state, local council, and the size and position of your structure. Many pergolas qualify as Exempt Development or Complying Development and require no formal approval at all. Some will need a Development Application (DA).

In most cases, Pergolux pergolas do not require planning permission. And because every structure is independently certified by a registered Australian structural engineer to AS/NZS 1170 and full NCC compliance, any council submission is straightforward. Read the full council approval guide →

Choose the Optimal Location and Orientation

The location of your alfresco is one of the most important decisions you'll make — it determines how comfortable the space is throughout the year.

1. Orientation

North-facing: The ideal orientation for Australian homes. Gets excellent winter sun when you want warmth, while remaining manageable in summer with appropriate shading. Best for year-round use.
East-facing: Pleasant morning sun, cooler in the afternoon. Great for breakfast areas and morning entertaining.
West-facing: Warm afternoon and evening light — perfect for sunset entertaining. Can get very hot in summer without adequate shading and screening.
South-facing: Stays cool and shaded, which works well in hot climates like Darwin or coastal Queensland, but can feel cold through winter in the southern states.

2. Connection to the House

Think carefully about where the connection to your home makes the most sense. A seamless flow between your kitchen or living room and the outdoor space is one of the most popular features in Australian home design — and one of the strongest drivers of property value.

3. Wind and Weather Protection

Consider prevailing winds in your area, particularly if you're in a coastal location. Pull-down zip screens on the windward side can make a sheltered space dramatically more comfortable — and they can be dropped or raised independently on each side of your pergola.

Choice of Material: Timber, Aluminium, or Steel?

The material you choose influences both the appearance and long-term durability of your alfresco — especially in Australia's climate.

Timber

Offers a natural look and warm aesthetic that suits many Australian architectural styles. Requires ongoing maintenance — oiling, sealing, or painting depending on the species and your climate. A practical choice for DIY as it's easy to cut and work with standard tools. Not ideal for coastal environments where salt air accelerates deterioration.

Aluminium

The material used in all Pergolux structures — and for good reason. Aluminium is lightweight, very strong, and virtually maintenance-free. Powder-coated aluminium resists corrosion, UV damage, and coastal salt air, making it the best long-term choice across all Australian climates. No painting, no staining, no sealing — ever.

Steel

Very strong, but significantly heavier than aluminium and requires proper corrosion protection (galvanising or quality paint systems) to hold up in humid or coastal environments.

Design and Style: Finding the Right Look for Your Space

Whether you prefer a sleek modern louvre pergola with full glass enclosure, a classic structure with climbing plants, or a minimal design that disappears into your home's architecture — your creativity knows no bounds.

At PERGOLUX, you'll find a range of high-quality aluminium pergola systems designed specifically for Australian conditions, with components and accessories that let you create a space that's as functional as it is beautiful.

Step-by-Step Instructions for Building Your Alfresco

1. Create the Foundation

Unlike colder climates, the concern with footings in Australia isn't frost depth — it's soil type and drainage.

Most residential alfrescos are built on a concrete slab or post footings. A 100mm reinforced concrete slab is typical.
In areas with reactive clay soils (common in Melbourne and Adelaide), you may need deeper or engineer-specified footings. A soil test will clarify what's required for your site.
Ensure the slab has adequate drainage fall — a minimum 1:100 slope away from the house is standard.

If you're using a Pergolux kit, the installation guide specifies exactly what size footings are required for each post, and the engineering certification accounts for the relevant load conditions for your location.

2. Assemble the Frame Structure

Accurate cuts and precise fixing of the supporting structure are critical for a safe, square result.

Choose your materials and tools to match your level of experience. If you're building in timber, follow your structural plans carefully and ensure all connections comply with the relevant Australian Standards (AS 1684 for timber framing).

If you're using a Pergolux kit, the components are pre-engineered, pre-drilled, and colour-coded — designed as a 3–6 hour DIY project for two people, with video assembly instructions available at every step.

4. Install Screens and Enclosure Options

Adding screens or glass walls is what transforms a shade structure into a genuine all-weather outdoor room:

Retractable zip screens: Keep insects out, block wind, and add privacy while maintaining airflow on milder days. Each side operates independently.
Glass walls: Full weather enclosure with the light and openness of being outside. Think of it as adding an extra room to your home — a sunroom, a dining room, a retreat — that happens to have no ceiling other than the sky.

5. Install Windows, Doors, and Ventilation

Good cross-ventilation is essential in Australia's climate, particularly in humid coastal areas and the tropics. Ensure you have enough openable panels to create airflow on warm days.

On a Pergolux, opening the louvres partially provides natural ventilation even when screens or glass walls are in position — giving you full control of the environment without having to choose between comfort and protection.

Interior Design and Climate Control

Once the structure is up, the finishing touches determine how much use you actually get out of it — and how comfortable it feels across every season.

Infrared heater: The Pergolux Heater uses infrared technology to deliver direct warmth to where you're sitting, not just the air around you. Rated up to 2000W, IPX5 weather-resistant, and rated for up to 5,000 hours of heating performance. Snaps directly into the pergola's rain gutter via SnapFIT™ — no drilling required. Essential for evening use in the cooler months across southern Australia.
LED strip lighting: Integrated cleanly into the pergola frame, so you can use the space well into the evening without visible cabling.
Everglow: Pergolux's ambient glow and atmosphere lighting system — also SnapFIT™ compatible.
Ceiling fan: A practical addition in most Australian climates. Dramatically improves comfort on warm days and draws cool air through on summer evenings.
Outdoor furniture: Choose materials rated for Australian UV exposure — the sun is harsh on finishes not designed for it. Aluminium frames, teak, or quality synthetic rattan all perform well.

Keep in mind: large glass panels let in both warmth in winter and heat in summer. Good air circulation is key. On a Pergolux, the adjustable louvres and optional integrated ventilation mean you can dial in exactly the conditions you want at any time of day.

Safety Instructions for Self-Assembly

Safety is important throughout the build. Wear appropriate PPE — gloves, safety glasses, and steel-capped boots as a minimum. Use proper scaffolding or an approved work platform if working at height.

Electrical connections, structural modifications, and plumbing work must be done by a licensed tradesperson — this is a legal requirement in Australia, not optional.

FAQ

How long does it take to build an alfresco yourself? This depends on your level of experience and the size of the project. A Pergolux pergola kit is designed as a 3–6 hour assembly project for two people. A larger custom-built structure may take several weekends, particularly if you're working part-time around other commitments.

How deep do footings need to be for an alfresco in Australia? This depends on your soil type and local conditions rather than frost depth (unlike colder climates). In stable soils, 300–450mm is typical for post footings. In reactive clay soils — common in Melbourne and Adelaide — you may need deeper or specially engineered footings. A structural engineer can advise for your specific site. Pergolux installation guides specify the footing requirements for each model.

What is the minimum size for a comfortable alfresco? For a genuinely usable entertaining space with room to move, aim for at least 12–15 m². A 4m × 4m or 3m × 5m footprint is a practical starting point for most households.

Can I add to my Pergolux later — screens, glass walls, or a heater? Yes. Every Pergolux accessory is designed to be added at any time via the SnapFIT™ system with no drilling into the frame required. You can start with the structure itself and build out your outdoor room over time.
