    How Much Does an Alfresco Extension Cost?

    Alfresco extension costs depend on a wide range of factors, including materials, features, and the size of the space. From a simple, shaded outdoor setup with chic bistro seating to an elaborate outdoor kitchen perfect for entertaining, their endless customisability means the total cost can vary significantly. In this blog, we break down the factors that influence the cost of your alfresco – so you can budget accordingly and create an alfresco design that perfectly suits your lifestyle.

    Factors Affecting Alfresco and Patio Prices in Sydney

    Planning your alfresco budget? Let’s break down some of the factors that will affect the cost.

    Roofing and Shade Solutions

    Adequate shade is an essential element in any outdoor area, allowing you to enjoy the space during rain and shine alike. Even if part of your alfresco area sits under your main roof, you may want some extra shade on those extra-sunny days. Awnings and pergolas are great for this purpose. Your alfresco’s roof cost will vary depending on:
    • Material: Polycarbonate roofing tends to be more budget-friendly, whereas insulated roofing sits at the higher end of costs.
    • Shape: A simple flat roof will cost more than a curved or gabled design or one with decorative elements.

    Flooring and Decking

    The flooring for your alfresco area is an important consideration. It needs to be sturdy enough to hold up against the elements, while also contributing to the aesthetics of your space. Popular options include:
    • Paving: Concrete pavers and slabs tend to be a cost-effective solution, although premium pavers or special designs may add to the cost.
    • Timber Decking: Versatile, durable, and aesthetically pleasing, classic hardwood timber is a popular choice of decking. The cost will vary depending on the variety of wood.
    • Composite Decking: A blend of natural timber and synthetic materials, composite decking may be pricier upfront, but it makes an excellent low-maintenance solution.

    Features

    The beauty of the alfresco area is that it can be customised to your heart’s content, with different features to suit different uses and lifestyles. Your alfresco cost can increase if you add:
    • An Outdoor Kitchen: The cost of adding an outdoor kitchen will vary depending on how large and elaborate it is.
    • Built-In Seating: Built-in seating can give your alfresco a cohesive look, but it requires more structural changes, which will add to the cost.
    • A Fire Pit: Fire pits are a great way to add ambience to your space. An elaborate design that’s custom-built for your space will cost more than a simpler option.
    • Lighting: A well-lit alfresco area ensures a safe and functional space. From enchanting fairy lights to functional spotlights and downlights, lighting can vary in price.
    • A Water Feature: Fountains are another way to enhance the ambience of your space, and come in a variety of designs ranging from simple to ornate.

    Structural Changes

    If you already have a setup for your alfresco outside, such as a paved area, installation will be more straightforward. However, costs can increase if you need to:
    • Install a deck
    • Remove existing structures
    • Add built-in seating
    • Add stairs

    Enclosing the Space

    While alfrescos are the epitome of outdoor living, sometimes you want a little more privacy – and a little more shelter from the elements. The effect this has on your alfresco cost depends on what you choose.
    • Outdoor Curtains: Stylish outdoor curtains are an affordable way to block out excess sunlight and give your space more privacy.
    • Outdoor Blinds: Depending on the style of outdoor blinds you choose, these can be pricier than outdoor curtains – so it depends on what works with your space.
    • Privacy Screens and Fences: These are available in a range of low-cost and higher-end options.
    If you prefer more shelter, you may consider fully or partially enclosing your alfresco and building a sunroom extension. A versatile addition to any home, your sunroom can be enclosed with flyscreens or glass walls to let the outdoors in while still protecting from the elements. Naturally, a sunroom extension will be more expensive than a simple set of outdoor curtains or blinds. However, as sunrooms are an excellent way to extend your living space, they are often worth the cost.

    Labour

    Having your alfresco area professionally built will increase the total cost of your alfresco. However, hiring professional alfresco, deck, or patio builders in Sydney is often worth the added expense, especially if your alfresco requires significant structural changes. Not only will they save you time and effort, but they will also ensure excellent quality, which can increase your home’s value in the long run.

    Approvals

    Building your alfresco close to a boundary line, installing utilities, or building in specific locations (such as heritage-listed areas) may require council approval, adding to the total cost. At Austek Home Improvements, we handle the paperwork – so you can focus on designing your dream space.

    Alfrescos on a Budget: Tips and Tricks

    Want to stick to your budget and have a stunning outdoor space to enjoy? By making wise decisions, you can do both!
    • Decide what your main priority for your alfresco is, and plan your space around that. This can help you discern what’s worth spending money on.
    • Consider when to spend and when to save. Professional construction is worth investing in, whereas decor and furniture can be thrifted or can even make a fun DIY project!
    • Simple additions like fairy lights and potted plants are typically quite affordable, but can instantly elevate the look of your space.
