Important Information: Base Information and Anchoring
This Palram greenhouse is not supplied with a floor. It is essential that it is constructed on a suitable concrete or slab base. The optional Palram Anchoring Kit adds extra protection to your greenhouse from strong winds, protecting it in gusts of up to 60 mph. Using the anchoring kit, the greenhouse can be secured to the base of your choosing and anchored into soft or hard surfaces. It is easy to install and, if ordered, will be delivered with your greenhouse.


The Palram 8x20 Bella Silver greenhouse is an attractive choice for anyone looking for a colossal greenhouse with a twist. In this case, the Bella's twist in design is a bell-shaped structure that contrasts the apex roof of the classic greenhouse. This shape has a purpose, as the curved sides of the Bella are exceptional at resisting heavy winds and diverting snowfall that can build up in heavy loads on greenhouse roofs. Over 150 square feet of storage space ensures this 8x20 Bella has all the space you require for some of the most adventurous and expansive garden projects imaginable.


The 8x8 Bella Silver greenhouse features a variety of components that bring the quality of the overall greenhouse to the next level. This includes four upper vents that can be manually opened to alter the humidity and temperature of your growing area, which is even more effective when used in combination with the double doors to create a draught. A magnetic catch is included with each of the doors that attaches to the magnetised base and allows them to snap in place, keeping the doors open wide.

It would be a mistake to overlook the core materials that give the Bella its fantastic build quality, however. For example, a galvanised steel base lays the groundwork for a sturdy structure around the greenhouse's perimeter. Built on this solid foundation, the aluminium frame extends the Bella's strength and − like the entirety of the Bella − is resistant against corrosion and rust.


At elbec, we are excited to offer a fantastic range of accessories for those who want to enhance their greenhouse in order to improve its capacity to do certain tasks. Many enjoy the increased control offered by an Automatic Vent Opener, which utilises the ambient air temperature to open up a vent and allow for more airflow. The item requires no electricity. It instead features a wax cylinder that expands and contracts to open and close a piston, all depending on the air temperature.

Those concerned with making the most of their space and having the potential to expand the scale of gardening projects will love the Two Tier Staging. This accessory is freestanding and easily moved thanks to a light polycarbonate structure. It is able to withstand a load of up to 40kg on the top shelf and 160kg on the lower shelf. Perforations on both levels ensure excess water can easily run off.

Additional Features

The Palram 8x8 Bella Silver greenhouse will need to be assembled on a flat section of ground, but comes with its own steel perimeter base for easy building. Assembling the Bella is made simple with written instructions from the manufacturer. Once the base is in place, the aluminium frame is easily screwed in place. Palram's polycarbonate glazing is designed to slot in place in a straightforward manner. Virtually unbreakable 6 mm wall and roof and 4mm door and window twin-wall polycarbonate panels maintain ideal temperatures and protect from strong sunlight exposure. It might take an afternoon or a whole weekend to assemble your Bella, depending on your DIY experience, but the process can be surprisingly rewarding.

Once complete, the greenhouse requires little maintenance thanks to its rust-free components and great build quality. Palram trusts its workmanship so much that a five-year warranty is offered on the product as standard. Check the manufacturer's instructions regarding the coverage to ensure you have the full details and can make sure your warranty is valid.
