Everything you need to know about garden sheds

A garden shed gives you a dedicated space for tools, equipment, and outdoor supplies that would otherwise clutter the garage or take up room inside the house. A garden shed is one of the most practical additions to a section, providing weatherproof storage close to where garden tools are used.

Key takeaways

  • The most commonly purchased garden shed size for a residential NZ section is around 1.8m x 2.4m, providing enough space for a lawnmower, hand tools, and garden chemicals.
  • Buy slightly larger than your current needs suggest. A shed fills up faster than expected as the garden develops and equipment accumulates.
  • Most garden sheds under 10 square metres are exempt from building consent requirements, but rules vary by council. Always confirm with your local council before purchasing.
  • A solid, level base is essential for any shed regardless of material or price. An uneven base causes the structure to rack and doors to sit out of alignment.

What is the size of a standard garden shed?

Standard garden shed sizes in New Zealand range from compact 1.2 metre by 1.8 metre units suited to a small selection of tools through to larger 3 metre by 6 metre structures that function as a full workshop or multi-purpose storage space. The most commonly purchased garden shed size for a residential section is in the range of 1.8 metres by 2.4 metres, which provides enough floor area for a lawnmower, hand tools, garden chemicals, and a modest amount of additional storage.

  • Small sheds (1.2m x 1.8m): suited to a basic selection of hand tools and garden supplies
  • Medium sheds (1.8m x 2.4m): suited to a lawnmower, hand tools, and garden chemicals
  • Large sheds (2.4m x 3m and above): suited to ride-on mowers, bikes, and workshop storage
  • Extra-large sheds (3m x 6m and above): suited to full workshop setups and multi-purpose storage

When choosing a size, buy slightly larger than your current storage needs suggest. A shed that is comfortably adequate on the day you install it will fill up faster than expected as the garden develops and equipment accumulates.

How to choose the right garden shed

The right garden shed for your section depends on what you need to store, how much space you have, and the conditions the shed will face.

  • Steel sheds suit most New Zealand residential sections and require minimal maintenance
  • Timber sheds suit visible garden positions where appearance is a priority
  • Plastic sheds suit coastal properties where salt air is a concern

A Zincalume or powder-coated finish extends the life of a steel shed in New Zealand conditions. Choose a shed with a floor included or confirm the base and floor requirements before purchasing.

How to build a garden shed from a kit

Most garden sheds sold in New Zealand are available as kit sets designed for homeowner assembly. A kit shed comes with all the structural components, panels, fixings, and instructions needed to complete the build. The construction process follows a consistent sequence regardless of the specific shed model, and most standard kit sheds can be assembled by two people over a weekend.

  1. Check for underground services before any ground preparation work begins
  2. Confirm council consent requirements for your shed size and site
  3. Clear vegetation and level the site to the full shed footprint plus clearance on all sides
  4. Prepare a solid, level base before assembling the shed frame
  5. Read the full instruction manual and check all components against the parts list before starting
  6. Work with a second person throughout, particularly during wall panel and roof installation

What base does a garden shed need?

A concrete slab is the most durable and recommended base for a garden shed. It provides a stable, level, moisture-resistant surface that protects the shed floor and frame from ground contact and water. A compacted gravel pad or a timber bearer frame on concrete footings are practical alternatives where a concrete pour is not feasible. Whichever base type you use, it must be fully level before the shed frame is assembled, as an uneven base causes the structure to rack and the doors to sit out of alignment.

Frequently asked questions

Do I need a building consent for a garden shed in New Zealand?

Most single-storey garden sheds with a floor area under 10 square metres are exempt from building consent requirements under the Building Act 2004, provided they are not used for habitation and meet the setback requirements for your property. Rules vary by council and zone, so confirm the requirements with your local council before purchasing and installing a shed. Sheds larger than 10 square metres or those positioned close to a boundary may require consent regardless of their intended use.
