Complete pricing guide for all extension types and budgets
Second storey extensions on sloping Glen Waverley blocks typically cost $300,000-$660,000 due to specialized engineering requirements. Sloping sites often require additional foundation work, retaining walls, and split-level designs. Benefits include potential walk-out basements, elevated views, and natural light maximization. Budget 15-25% extra for site-specific structural solutions.
Geotechnical Reports: Essential for sloping Glen Waverley blocks - budget $2,000-$5,000 for soil testing and site classification
Retaining Walls: May add $15,000-$50,000 depending on height and engineering requirements for slope stabilization
Split-Level Designs: Can reduce excavation costs and create natural separation between living zones while following terrain
Walk-Out Basements: Possible on sloping sites, adding valuable garage, storage, or living space below the extension
Elevated Views: From upper levels on sloping Glen Waverley blocks can significantly increase property value and appeal
Drainage Solutions: Critical - stormwater management, subsoil drains, and appropriate grading prevent future issues

Sloping Block Extensions in Glen Waverley: Sloping blocks create unique opportunities for second-storey extensions with walk-out basement access. Challenging terrain requires specialised engineering for foundations and retaining walls, but rewards with spectacular elevated views. Projects often integrate the extension into the slope, creating split-level living with garage/storage below and premium living spaces above. Complex site access may require crane lifts for materials. Design maximizes view corridors while managing drainage and erosion.
