Frequently Asked Questions

How Do I Place an Order?

You can purchase through one of our stockists, or directly through our website. Buying through our retailers offers free shipping and expert support.

If you need help, call us at 1800 757 610 or email sales@wintergardenz.com.au.

Are Your Greenhouses Made in Australia?

Yes! Our greenhouses are made in our factory in Somerville, VIC and are Certified Australian Made. Designed for local conditions, they offer durability, support, and peace of mind.

Kitset Greenhouse Delivery

Greenhouses are shipped to the nearest Mainfreight depot due to weight. You’ll need a trailer to collect them, and the depot will forklift the crate onto it.

Check our Greenhouse Weights and Dimensions page to see how your greenhouse will be packed for collection.

What Tools Do I Need for Assembly?

  • Cordless impact driver (with supplied 10mm nut setter/socket)
  • Phillips head screwdriver
  • Set square, spirit level, tape measure
  • Scissors or sharp knife
  • Bucket of warm soapy water (helps with rubber beading)

Where Can I Find Base Dimensions?

Go to the product page of your greenhouse size (e.g., 10x16ft glasshouse) and click 'Download Foundation Page'.

How Difficult Is Assembly?

Watch our installation videos to decide. Most greenhouses can be built with patience and time, but if you'd rather have it assembled professionally, ask us for a quote.

For reference, a 8x8ft greenhouse takes two people about a day to build.

Why Choose Winter Gardenz?

Unlike many competitors, we display our greenhouses in retail outlets. Cheaper alternatives may lack:

  • Sturdy framing guaranteed not to rust
  • 4mm toughened safety glass
  • New Zealand manufacturing and customer support
