Are double-storey homes more expensive per square metre?

Generally yes. The reasons include structural steel for upper-floor spans, additional plumbing runs, stair engineering, and upper-floor windows. The gap varies by builder and specification. Ask each builder to quote your specific plan on your specific block.

Does a double-storey home work on a sloping block?

Often very well. A split-level double-storey design can hug the slope and reduce cut-and-fill costs. Talk to a builder who specialises in sloping-block work; a poorly designed double-storey on a slope can be significantly more expensive than the same design on a flat block.

About this collection

Double-storey home designs unlock two clear advantages in Adelaide: they let families put more floor area on a narrower or higher-value block, and they let sloping blocks work with the fall rather than against it. On a 10-12m frontage in Prospect, Norwood or Unley, a well-designed double storey delivers 4 or 5 bedrooms plus a proper media room where a single-storey equivalent simply will not fit. Costs per square metre run 8-15% higher than a comparable single-storey once structural steel, upper-floor plumbing, engineered stair, and additional windows are counted — but total build cost is often lower because the footprint is smaller. When comparing plans, look closely at three things: where the master sits (ground floor for future-proofing versus upstairs for privacy), how the stair is placed relative to the front door and living zones, and how the upper-floor bathrooms are stacked over ground-floor wet areas to keep plumbing efficient. Ask specifically about SDA/mechanical ventilation on upper levels, upper-floor waterproofing, and how the plan performs in the SA summer heat once upper-level ceilings sit close to the roofline. If you are unsure, request quotes on your block for a comparable single- and double-storey plan side by side.
