# Backyard Landscaping & Outdoor Cost Estimator

Estimate your backyard remodeling, decking, paving, and fencing costs. Free interactive calculator with custom suburb-level breakdowns. No signup required.

Timber or composite decking, concrete or stone paving, boundary timber fencing, concrete sleeper retaining walls, and soft landscaping elements are all priced based on their specific units of measure (square metres or linear metres).

Each component is loaded with current market-standard pricing derived from active landscape contractors in Sydney, Melbourne, Brisbane, Adelaide, and Perth. These base rates are adjusted dynamically according to:
