What counts as a sloping block?

A block with more than about 1m of level change across the building envelope. Anything over 3m of fall usually needs a split-level or stepped design to avoid runaway cut-and-fill and retaining wall costs.

Are sloping-block designs more expensive?

Almost always. Extra costs come from engineering, retaining walls, deep footings, stormwater management, and the extra time on site. Ask each builder for a specific site-cost quote against your survey.

Sloping-Block Home Designs Adelaide

Every home design in our library flagged as suitable for sloping blocks. Sloping-block work needs an experienced builder: engineered footings, retaining walls, cut-and-fill economics, and design that responds to the slope rather than fighting it.

About this collection

Sloping blocks are common in the Adelaide Hills, Cherry Gardens, Aldgate, Belair, Blackwood, Mitcham and the eastern foothills. Split-level and stepped designs are typically more cost-effective than cut-and-fill on slopes greater than 3 metres of fall across the building envelope. Talk to a sloping-block specialist builder about your survey and BAL rating before committing to a design.
