Is a single-storey home cheaper to build than double-storey?

Not always. Single-storey uses more slab area and more roof for the same total floor area, which can offset the saving on stairs, structural steel and second-storey windows. The comparison depends on block width, roof pitch, and inclusion levels. Ask builders for quotes on your block against comparable single- and double-storey plans before deciding.

Do all Adelaide builders offer single-storey designs?

Most active volume, project and custom builders in SA offer single-storey designs, but the breadth varies. Custom builders can design a single-storey home to any brief; volume builders offer set catalogue plans.

About this collection

Single-storey homes are the Adelaide default for a reason. They suit downsizers who want no stairs for the next twenty years, growing families who value the accessibility of ground-level living, and buyers on flat blocks with enough footprint to spread out. Because the plan uses more of the block, site cost sensitivity is highest here — slab classification, cut-and-fill and stormwater strategy all directly influence the final quote. Most active Adelaide builders — from volume names like Metricon and Rossdale through project builders like Fairmont and La Vida to full-custom firms — offer strong single-storey catalogues, so comparison should focus on room proportions, master-suite privacy, and how well the plan handles Adelaide's summer sun on a north-facing living zone. Ask each builder about slab classification (typically M or H1 in SA), site cost inclusions, and whether the catalogue plan works with your specific council's setback rules. Single-storey builds also tend to complete faster than a double-storey of comparable area — usually 8-12 months from slab pour, versus 12-16 months for a comparable double. If accessibility, no-stairs living, or a straightforward build sequence matter to you, single-storey is worth shortlisting first before comparing against double-storey alternatives.
