The Sunhaven Greenhouse

Ready-to-Ship Cross Country

What Makes The Sunhaven the Ultimate Backyard Greenhouse?

The Westgrove is more than just another greenhouse kit. It is one of the best deals we have ever offered. Built in our most popular 8×12 size, this limited-edition model gives you more space than the typical backyard kit without the hassle of a custom order. It features desirable all-glass sidewalls for timeless beauty and growing performance, plus your choice of a glass or optional twinwall polycarbonate roof.

Normally, a black frame comes with an upgraded custom color charge. The Westgrove though is available in either black or white at no extra cost. That makes this greenhouse an incredible value for gardeners who want a larger kit, picture book glass glazing, and a sleek black frame finish at a stock model price.

Important Note: The price on this Ready-to-Ship model will increase in the new year. To lock in the current low price, be sure to order before December 31.

Get to know The Sunhaven

The Sunhaven Greenhouse is designed to bring professional-grade durability and plant-friendly design into the backyard gardener’s budget. Its 8×8 footprint gives you significantly more growing room than standard kits, while the strong polycarbonate glazing provides insulation, diffused light, and protection against weather extremes. It’s a greenhouse that works as hard as you do: whether you’re starting seeds, growing vegetables, or keeping ornamentals thriving through the seasons.

Unlike many greenhouses, The Sunhaven doesn’t require a costly concrete foundation. Most gardeners simply use a row of 4x4s to create a secure threshold, but you can also choose a concrete base if you prefer. The key is starting with a square, level foundation.

In most areas, a greenhouse of this size won’t require a building permit, but it’s always smart to check your local requirements before you begin. Once your foundation is ready, the pre-cut, pre-drilled frame kit comes together over a weekend with a few helping hands, so you can be planting in no time.

The Sunhaven is a ready-to-ship 8×8 model featuring 6mm twinwall polycarbonate glazing, sturdy aluminum framing in your choice of white, green, or brown, and a plant-friendly design built to last, all for $4,495. Thinking of a different size or glazing? Reach out to our greenhouse experts who are happy to help you create your own made-to-order greenhouse.

For ease and simplicity, you can place your Sunhaven order directly through our online store. If you’d rather have a more personal approach, one of our greenhouse experts can answer your questions and help you choose the right greenhouse for your space, growing goals, and budget. When you work with an expert, you also have the option to reserve your greenhouse with a 25% deposit instead of paying in full upfront.

Like all Cross Country greenhouses, The Sunhaven is built for strength and withstands up to 32 lbs. of snow per square foot and winds up to 85 mph. Weather stripping helps maintain steady temperatures inside, while two solar-powered automatic roof vents keep fresh air circulating for healthy plants. Ideal for three-season growing in most climates, the Sunhaven is a fantastic season extender to grow earlier in the spring and longer through the fall.

And with a lifetime frame warranty and ten-year glazing warranty, you can count on your greenhouse to be a long-term part of your garden.
