Home Designs and Inclusions Explained: How to Read a Builder's Price List

Single vs double storey, and the dimensions that matter

Single-storey homes on their own title are cheaper to build per square metre, faster, and easier to orient for light and breeze; double-storey homes put the same floor area on a smaller, cheaper lot — which is why corridor estates with $400,000–$500,000 lots default to two storeys. The trade-offs are real: stairs, upstairs temperature management, and slightly higher build cost per m² for the second storey. On wide greenfield lots the single-vs-double decision is genuinely open; on narrow lots below ~10m frontage, double-storey is usually the only way to four bedrooms.

Three dimensions drive livability more than any photo: lot width and home width (a 16m-wide home on a 12.5m lot is a design failure), ceiling height (2.4m standard reads low; 2.55–2.7m transforms light and feel), and orientation (living areas facing north, bedrooms east, garage west as the heat buffer). Check all three on the plan, not the render.

Reading an inclusions schedule like a professional

The inclusions schedule — not the floor plan — is where builders actually compete. Read it line by line and convert it to questions: kitchen benchtop material and thickness (20mm laminate vs 40mm stone), appliance brands and model numbers (not '900mm stainless'), heating and cooling (ducted vs split, zoned how?), floor coverings (which rooms get what), windows (size, glazing, frames), and the facade (which one is included — the render shows the premium one). Two schedules with identical bedroom counts can differ by $40,000 of genuine content.

Then normalise: ask each builder for a quote on the same specification — your specification — rather than comparing their inclusions against each other. This single step converts a marketing exercise into a tender, and it is when 'expensive' builders sometimes become the cheapest. Our home designs section covers the design families volume builders offer across the corridors we profile.

Frequently asked questions

Is single or double storey cheaper to build?

Single storey per square metre; double storey often cheaper overall because it fits on a smaller, cheaper lot. Compare total project cost — land plus build — rather than per-m² rates alone.

What should be in a standard inclusions list?

At minimum: full kitchen (benchtop, appliances specified by brand), floor coverings throughout, heating/cooling, window furnishings often excluded, standard facade, driveways sometimes excluded. Anything not listed is either excluded or an allowance — ask which.

How do I compare two builders' prices fairly?

Give both the same specification in writing and ask for a fixed price against it, including site costs for your specific lot. Comparing base prices with different inclusions is comparing definitions, not prices.

What is a 'facade upgrade' and do I need one?

Builders typically include one standard facade; the renders show premium options costing $5,000–$25,000. Estate covenants sometimes mandate minimum facade standards, so check the covenant before deciding the standard facade will do.
