How much does an alfresco renovation cost in Perth? An alfresco renovation in Perth costs between $15,000 and $60,000 with House & Co, depending on the size of the area, roof type, flooring material, and whether an outdoor kitchen is included. A basic alfresco refresh (new paving, ceiling fan, downlights) starts from $15,000. A full renovation with a louvre roof, outdoor kitchen, and premium paving reaches $60,000 and above. These are guide prices only — structural additions require permits and a fixed-scope quote.
What is the most popular alfresco renovation in Perth? In 2026, the most requested alfresco briefs in Perth are: louvre roof replacement (adjustable for year-round use), limestone or porcelain paver replacement, built-in BBQ and outdoor kitchen addition, and cafe blind or vergola screening. Perth’s climate — averaging 3,200 hours of sunshine per year — makes the alfresco one of the most heavily used spaces in any Perth home.
Do I need a building permit for an alfresco renovation in Perth? Structural alfresco work — new roof, new posts, extending the footprint, or adding a pergola — requires a building permit from your local Perth council. Like-for-like replacement of existing roofing or paving without structural change generally does not require a permit. House & Co manages the permit application as part of the project scope — you do not need to deal with the council directly.
How much does a louvre roof cost in Perth? A louvre roof system for a standard Perth alfresco (5m × 4m) costs approximately $12,000–$25,000 installed, depending on brand, finish, and motorised versus manual operation. Stratco, Vergola, and Outrigger are common brands in the Perth market. Louvre systems allow year-round use of the alfresco — a significant functional upgrade in Perth’s variable spring and autumn climate.
What is the best paving for a Perth alfresco?Large-format porcelain pavers (slip-rated, frost-resistant) are the most popular choice for Perth alfrescos in 2026. Natural limestone and travertine remain popular in western and inner suburbs. Composite decking performs well but requires good drainage. Polished concrete is durable and seamless but can be hot underfoot in Perth’s summer. All options are discussed at the House & Co design consultation with a recommendation suited to your home and style.
How much does an outdoor kitchen add to alfresco renovation cost?An outdoor kitchen addition — built-in BBQ, sink, under-bench storage, and bar fridge — adds $8,000–$20,000 to an alfresco project depending on the specification. Plumbing (sink connection) adds $2,000–$4,000. A basic built-in BBQ with benchtop and storage starts from $5,000. A full outdoor kitchen with sink, bar fridge, rangehood, and stone benchtop reaches $15,000–$20,000.
Does an alfresco renovation add value in Perth? Yes — outdoor living improvements consistently perform strongly at resale in Perth given the climate and lifestyle expectations of the market. A well-executed alfresco renovation typically returns 50–70% of cost in added property value. In inner and western suburbs (Cottesloe, Nedlands, Subiaco, South Perth), buyers expect a functional outdoor living space as a standard feature — an inadequate alfresco can actively reduce buyer interest.
How long does an alfresco renovation take? A basic alfresco refresh (paving, lighting, screening) takes 2–4 weeks on site. A full renovation with roofing and outdoor kitchen takes 4–8 weeks. Structural additions requiring council permits add 4–8 weeks for approval before on-site work begins. House & Co manages the permit process — lodgement to approval is tracked throughout.
