Patios & verandahs in Pakenham & Cardinia Shire.

• Small bolt-on patio (3 x 3m to 4 x 4m): the bare-alfresco-slab retrofit. Three or four steel posts, bolted to existing house fascia, insulated panel or Colorbond roof. ~$8,000–$11,000.
• Medium bolt-on patio (4 x 5m to 5 x 6m): larger entertaining cover. ~$11,000–$16,000.
• Wraparound steel verandah: 15–30m of continuous run linking front, side and rear of the house. ~$18,000–$28,000 depending on length and roof.
• Freestanding pavilion patio: detached from house, posts all four sides. Suits pool surrounds and detached studios. ~$13,000–$20,000 for 4 x 5m.
• Full alfresco shell (under-cover entertaining room): roof, partial walls, ceiling fan, lighting, weather screens. ~$18,000–$25,000.

Insulated sandwich panel — why it’s worth it.

A single-skin Colorbond roof on a 35°C Pakenham summer day radiates downward heat — you can feel it sitting beneath. Insulated sandwich panel (Colorbond top + 50–75mm EPS foam core + Colorbond bottom) drops the radiant heat 8–12°C underneath and cuts rain noise from drumming to a soft hush. Adds $80–$140/m² over plain Colorbond. For a typical 4 x 4m patio (16m²) that’s a $1,300–$2,200 upgrade — almost always worth it on a north or west-facing entertaining area.

Single-skin Colorbond — when it’s right.

Plain Colorbond is fine for: carports (you’re not sitting under them), south-facing patios (less direct radiant heat), covered walkways (transit space, not long-stay), and budget jobs where the upgrade isn’t in the budget. The difference shows up most on hot afternoons and during heavy rain.

Bolt-on detail done properly.

The connection between the new patio roof and the existing house is the most common failure point on cheap patios. We use a steel fascia bracket bolted through the existing roof rafters (not just the gutter board), with full silicone seal and Colorbond flashing capping over. Where the new roof butts to an existing tiled roof, we step-flash properly with PVC or aluminium flashing under the tile course. Skipping this gives water ingress into the house cavity within a year.

Council setback rules for patios.

• Side setback: typically 1m clear from boundary in General Residential Zone. Patios at the boundary need neighbour consent under Building Regulations.
• Rear setback: typically 3m clear from rear boundary, less if behind existing dwelling.
• Maximum 50% rear-yard cover: ResCode rule limiting how much rear yard can be paved or roofed.
• Front setback: patios forward of building line need planning permit. Verandahs over a front porch usually fine if matching existing eave.

Most popular Cardinia growth-corridor patio.

The default 2026 Cardinia Lakes / Officer / Pakenham East patio: 4 x 4m insulated panel cover in Monument or Basalt, flat roof at 5° fall, three or four steel posts on 900mm pad footings, bolted to existing house fascia, integrated LED downlights, ceiling fan rough-in. Around $10,000–$13,000 supplied and installed including the building permit. Most owners ask for the downlights and fan rough-in even if they don’t install the fan immediately.
