Greenhouse Kit Prestige 8 ft. x 20 ft.

Structure color

The Prestige Greenhouse features a chic barn shape, a windowpane design and comes completely loaded with professional-grade accessories such as a two-tier bench and trellising kit.

The emphasis on safety is evident from the heavy-duty frame to the extremely safe polycarbonate panels. The sturdy, weather resistant and UV-protected extruded resin frame with its aluminum roof profiles improves both full-insulation and durability. The polycarbonate side walls give you clear views while the 4mm twin-wall roof panels diffuse over 90% of sunlight for a soft, even light.

The attention to detail continues through the design of the roof which provides ample headroom and more space to garden to the double doors that make it easy to go in and out, even with large trays of plants. There is also excellent ventilation due to the roof vent, automatic vent openers and side louver windows. This provides airflow, retains heat when the doors are closed, and helps you maintain correct moisture and temperature levels for your plants.

We keep it simple with a pin and lock assembly making the Palram – Canopia Prestige Greenhouse perfect for the growing enthusiast who wants something easy and beautiful!

  1. ChrisK Country: Ireland

    Mostly satisfied

    The greenhouse is mostly what I expected. Some parts feel less premium, but the overall functionality is not compromised. A good value for the price.
  2. astralquill8 Country: United States (US)

    Reasonable price…

    I am amazed at the excellent quality of this greenhouse, especially given the reasonable price. Assembly was straightforward too!
  3. cosmoquasar_77 Country: Portugal

    Mostly great, some assembly issues

    The greenhouse looks great and serves its purpose well. The assembly instructions were a bit confusing, but I managed to put it together.


No, it is not an option, it cannot be performed.
Yes, it can be disassembled, relocated and reassembled at a different location.
No, it is not an option to get doors on both ends.
It is not possible to install the Lean To Grow House’ door at the other side. It is possible to install only as shown in the instructions.
The greenhouses do not come with a floor or base.
Yes, the polycarbonate panels are high impact resistant and withstand hail.
The warranty for all our greenhouses is for at least 5 years, some for more. The crystal-clear single layer or twin-wall polycarbonate panels maintain their integrity, they do not discolor, opacify, fracture or shatter over time.
Each wall section can carry up to 44 lbs. at most – an entire wall would depend upon the greenhouse’ size.
It can be anchored to a foundation, depending on the greenhouse, some have compatible holes at the bottom of the greenhouse base, and some have their own integrated anchoring. Yes, the greenhouse can be anchored to concrete slab. It can be anchored directly to the ground using ground stakes (ground stakes are not supplied with the greenhouse kits). *Firmly connect the product to a level surface immediately after completion of the assembly. Anchoring this product to the ground is essential to its stability and rigidity. It is required to complete this stage in order for your warranty to be valid.
The Canopia Greenhouse can be used year-round, but there are several factors to consider. The two main factors are weather and plants. What are the plants you want to grow and how much heat or cold can they handle? No matter where you live, greenhouses can be 20-40 degrees hotter inside during the day and at night they will be the same temperature as the outdoors. This is without any supplemental heating or cooling. Depending on where you live, heating and / or cooling your greenhouse can make a difference. If you need to heat or cool your greenhouse in extreme weather conditions, you may want to consider a twin-wall greenhouse such as the Canopia Glory Greenhouse which has a 10mm polycarbonate covering.
