How Much Does A Shed Cost Per Square Metre?

The cost per square metre for domestic sheds is difficult to estimate because the square metreage is often very small.

However, we understand that it’s useful to have rough figures.

Cost Per Square Metre for a Typical Domestic Shed

The average cost of a SmartaBuild domestic shed is $22,500 aud. This covers an approximate size of 12m x 6m, resulting in a cost-per-square-metre of $312m2. 

Cost Per Square Metre: $312 m2.

Cost Per Square Metre for an American Style Barn

American style barns have vaulted centre aisles and are more complex structures. Consequently, a 16m x 4m American style barn can cost the same as the shed above: $22,500, resulting in a higher cost per square metre.

Cost Per Square Metre: $351 m2

Cost Per Square Metre for Small Domestic Sheds – Part 1 (Low Costs)

For domestic sheds that a small but relatively simple in design, the cost per square metre can be kept low. An 8.5m x 8m hay shed can cost $9,929, resulting in a low cost per square metre of $141. A hay shed is typically very simple in design, and only has three walls, leaving the side open for vehicle access.

This cost, as with all costs on this page, includes installation.

Cost Per Square Metre: $141 m2

Cost Per Square Metre for Small Domestic Sheds – Part 2 (High Costs)

Small domestic sheds often have high cost per square metreage because labour costs are a larger portion of total costs. So, for a shed 4.3m x 7m an approximate cost of $12,998 would result in a typical cost per square metre of $431.

Cost Per Square Metre: $351 m2

Cost Per Square Metre for Large Domestic Sheds – Part 1 (Low Costs)

The cost per square metre tends to drop as the shed gets larger and there is less difference in the cost per square metre price. A 20m x 12m might typically cost $41,684, resulting in a square metre cost of $210.

Cost Per Square Metre: $172 m2

Cost Per Square Metre for Large Domestic Sheds – Part 1 (High Costs)

Usually, the square metre cost stays low for larger domestic sheds. In some cases though, it can creep up. For an 18.5m x 7m shed with five internal bays, and two roller doors, the cost can be up to $43,154. This results in a high cost per square metre, but is an anomaly at this size.

Cost Per Square Metre: $333 m2

Cost Per Square Metre for Carports

Carports are the cheapest when calculated per square metre, as they have the fewest materials and are relatively quick and easy to erect.

A 6 x 12m carport could cost $12,558, resulting in a cost per square metres of $174.

A 12 x 8m carport can cost $11,450, resulting in an even lower cost per square metre of $119.

In rare instances that the carport is complex and requires custom engineering, the cost per square metre might go up. For example, an 8 x 7m carport with cantilever columns at different offsets can cost up to $17,500, resulting in a cost per square metre of $312.

Cost Per Square Metre: Usually $119 – $174. Sometimes over $300/m2.
