Custom Patio & Alfresco Deck Builders

A well-designed patio or alfresco deck can completely transform how you use your outdoor space. Instead of a basic concrete or paved area, decking provides a warmer and more inviting surface that works naturally with modern outdoor living.

At Northern Decking Co, we design patio and alfresco decks that integrate with the layout of your home. Each deck is built with proper structural framing, secure footings and materials suited to Western Australia's environmental conditions.

By focusing on both design and construction quality, we ensure your outdoor space becomes a comfortable and functional entertaining area.

Patio Decking Built for WA Conditions

Patio and alfresco areas in Perth’s northern suburbs are often exposed to direct sunlight, coastal winds and seasonal rainfall. Outdoor decking must therefore be built with materials and installation methods that can withstand these conditions.



Northern Decking Co installs decking systems that allow for proper ventilation, drainage and natural expansion of materials. We use corrosion-resistant fixings and structural framing techniques designed for coastal suburbs such as Mullaloo, Alkimos and Yanchep.


This ensures your patio deck remains durable and visually appealing for many years.

Perfect for Perth

Decking can significantly improve the comfort and functionality of outdoor entertaining areas.


Decking creates a softer, warmer surface than paving or concrete, making it ideal for everyday outdoor living.

Patio and alfresco decking is commonly installed for:

• Covered alfresco entertaining areas
• Outdoor dining spaces
• Patio upgrades and renovations
• Backyard entertaining zones
• Outdoor kitchen and barbecue areas

Where Patio & Alfresco Decking Works Best

Timber or Composite Patio Decking

Both timber and composite decking can be used for patio and alfresco areas, depending on your preferences and maintenance expectations.


Timber decking provides a natural appearance that blends well with gardens and landscaping. Many homeowners prefer timber for its warm aesthetic and ability to be refreshed through oiling or staining.

Composite decking offers a low-maintenance alternative designed to resist fading, moisture and wear. This makes composite decking particularly attractive for busy households that want a modern outdoor space without ongoing maintenance.


Northern Decking Co installs both options and can help you select the material best suited to your home.

Benefits of Patio & Alfresco Decking

Installing decking in a patio or alfresco area offers several advantages for homeowners.


A professionally built deck can transform a simple patio into one of the most enjoyable areas of your home.

Key benefits include:

• Creates a comfortable outdoor entertaining space
• Enhances indoor-outdoor flow from your home
• Improves the appearance of patios and alfresco areas
• Provides a warm surface compared to concrete or paving
• Adds lifestyle value and appeal to your property

Patio Deck Extensions & Upgrades

Many homes already have a patio or alfresco area but the space may feel limited or unfinished. Decking can be used to upgrade existing outdoor areas by extending the usable space and improving the overall design.


Northern Decking Co can extend existing patios with decking, create raised entertaining platforms or redesign outdoor areas to better suit modern living.

These upgrades allow homeowners to maximise the use of their backyard without major structural renovations.
