Core Product Features
-
Extra High Headroom & Spacious Interior: Unlike standard hobby greenhouses, our Gain Height design provides ample overhead space for tall plants (like tomatoes and climbing vines) and allows you to walk in and work comfortably without crouching.
-
Heavy-Duty Aluminum Alloy Frame: Constructed with a premium powder-coated aluminum frame that is naturally rust-proof and corrosion-resistant. Engineered to withstand extreme temperatures ranging from -20°C to 70°C, ensuring all-season performance.
-
4mm Twin-Wall Polycarbonate Panels: These impact-resistant panels offer 70% light transmission, diffusing sunlight to prevent plant burn while blocking 99.9% of harmful UV rays. This shatterproof glazing is a safer, more durable alternative to traditional glass.
-
Superior Windproof Stability: Includes a raised base and integrated anchor system specifically designed to secure the structure to the ground, providing enhanced stability during gusty winds and storms.
-
Smart Drainage & Ventilation: Features an integrated gutter system to channel rainwater away from the foundation and adjustable vents to control internal temperature and humidity levels effectively.
-
DIY-Friendly Setup: All parts are precision-prefabricated and labeled. With our detailed illustrated guide, assembly is straightforward and requires no specialized professional tools.

Do I need council approval to build a carport or awning in Australia?
In most parts of Australia, council approval or a building permit is required before constructing a carport—particularly for structures exceeding 10 m² in floor area. Local council regulations vary significantly across different states and municipalities, strictly governing factors such as maximum structural height, boundary setbacks, total footprint, and rainwater management compliance.
To ensure a seamless compliance process, we provide a comprehensive documentation package to assist with your building application. This includes certified engineering documents, detailed technical drawings, and 3D architectural renderings to help your local council or private certifier clearly visualize the structural integrity and design of your carport.
While we provide all the essential documentation required for submission, final approval remains subject to the assessment and regulations of your specific local council.
Our products are covered by a warranty for replacement parts as follows:
Warranty Coverage
- Aluminium Frames: 10 years – covers defects in materials, manufacturing, structural integrity, deformation, or corrosion under normal use and weather conditions.
- Polycarbonate Sheets: 3 years – covers material and manufacturing defects.
- Bracket Awnings: 3 years – covers material and manufacturing defects.
Customer Reviews
Fantastic greenhouse at an excellent price! Assembly was straight forward- I assembled this wholly on my own and it did take the whole day. My advice would be to follow instructions and be precise it will benefit/reward you in the end. The sheets are Crystal clear, and it lets in so much light, keeps a good even temp with good humidity. A dream come true to own one....saving up for the next one now! do your self a favor and buy it, you will not be disappointed
For a greenhouse at this price point, the build quality is excellent. The aluminium frame is lightweight but once it’s fully bolted together and anchored to the base, it’s very solid. We just had a particularly gusty weekend here in Adelaide, and it didn't budge or rattle at all.
The sliding door is smooth, and the roof vent is a must-have for keeping the airflow going on warmer days. Assembly took me about 4 hours on a Saturday—everything was numbered correctly and the instructions were easy to follow. It’s a great feeling to finally have a dedicated, frost-free spot for my winter veggies. Shipping was quick and the packaging was robust. Highly recommend Kings Awning!
I’ve been wanting a greenhouse for ages, but I was worried about my limited garden space. This 6x4ft model is the ideal solution—it’s compact enough to fit neatly in the corner of my yard but surprisingly spacious once you’re inside. I’ve managed to set up two tiers of shelving for my seedlings and exotic tropicals.
The polycarbonate panels diffuse the harsh afternoon sun perfectly; I’ve noticed my orchids are much happier and aren't getting scorched anymore. It also holds the humidity beautifully overnight, which has been a lifesaver for my propagation projects. If you’re a hobby gardener with a smaller space, this is a fantastic, high-quality entry point.
Absolutely love this green house and so do all of my plants easy to put together by yourself even easier if you have another person help. Price definitely worth the quality. Will definitely be ordering another one maybe a bigger size
