Before getting caught up in the excitement of extending, renovating or building a brand new home on a slope, make sure you’ve got sufficient site provisions in place. A sloping block can be a fantastic opportunity, allowing creative use of the land, not to mention if it offers great views — but it’s also where due diligence matters most. To keep your home safe, stable, dry and happy, it’s crucial to put the proper precautions in place from the start.
Sloping block checklist:
- Site stormwater paths & topography: How steep or uneven is the slope, and where does runoff naturally go when it rains?
- Soil information: Get geotechnical data early to check soil stability, damp-prone areas, or groundwater issues.
- Drainage and water flow: Ensure plans prevent water-related erosion, ponding, and foundation moisture issues.
- Council rules & building envelopes: Check local cut/fill controls and compliance limits so your design remains buildable.
- Retaining walls and access: Plan ahead for earthworks, retaining, and machinery access to avoid hidden budget surprises.
- Services and connection points: Identify power, sewer, and water lines early to avoid expensive relocations on a slope.
- Hazards and site limits: Map out easements, flood/fire hazards, or heritage restrictions that affect usable space.
- Price comparisons: Evaluate total projected site works, engineering, approvals, and timelines—not just the initial land price.
Questions to ask your builder:
- What foundation type would they expect (slab vs piers vs engineered system)?
- What’s the likely earthworks/retaining wall range for your design intent?
- What access strategy would they use?
- Any “red flag” risks they foresee from the site data?
