Are you new to gardening? Someone with a few growing seasons under your belt? New or experienced, a backyard greenhouse allows you to take the your ‘green thumb’ to the next level. And, with a Horizon Structures pre-built greenhouse it’s easy and relatively inexpensive to do!
A greenhouse in the backyard allows you to…
A PREBUILT Horizon Structures greenhouse allows you to get started immediately! NOT a kit ~ NO ASSEMBLY required.
As a general rule, greenhouses are relatively light compared to their size and may blow over or suffer wind damage if not properly anchored. We’re proud to say, there’s nothing lightweight or flimsy about a Horizon Structures greenhouse. They’re heavy and sturdy incorporating a robust 4×4 pressure-treated wood foundation ‘frame’ that keeps the structure upright, square and solidly in place.
This extra strong foundation – or base frame – securely holds the structure together AND enables you to easily anchor it firmly to the ground for increased peace of mind.
The pressure treated wood also reduces (or eliminates) damage from dampness in the ground and insect infestations.
Clear polycarbonate panels make up the roof and sides of the greenhouse. They are neatly sandwiched between the interior wood framing and Azek exterior trim.
Azek is a multi-purpose construction material made of cellular PVC. It is durable and long-lasting. It does NOT require paint for protection but holds paint well should you decide you want something other than the standard white.
Azek never needs maintenance. And, unlike wood, it resists mold, mildew, stains, and scratches. It’s splinter-free and comes with a 30-year manufacturer’s warranty.
The 8mm twin wall polycarbonate panels offer improved insulation for both hot and cold weather and are superior to fragile glass or plastic sometimes used in greenhouses. In the unlikely event these durable panels need replacement, simply unscrew the (exterior Azek) trim and put in a new panel.
Our greenhouses are beautifully crafted from the ground up by Amish carpenters and include a pressure treated, 4 x 4 Southern Yellow Pine (SYP) base that will stand the test of time. All that’s required is a level, well-drained area. A specially prepared site is not necessary unless you prefer that route.
The ‘floor’ of your greenhouse can be finished in a myriad of ways before or after delivery…
- Concrete slab
- Pavers, bricks
- Your choice!
