Please Note: Because of the lightweight materials, this greenhouse is not suitable for windy or exposed areas. In these circumstances we recommend a glass greenhouse which is heavier and will remain grounded. This greenhouse is also not supplied with a floor, so for greater stability it should be constructed on an appropriate concrete or slab base.


A hexagonal structure looks distinct, and creates a pleasant interior without any tight corners. Garden owners on the hunt for a greenhouse with a user-friendly design that makes it perfect for relaxing or working from home as well as growing plants will find a lot to love in this 12ft Palram Oasis. A garden building like this one can be an ideal way to make the most of a picturesque spot in your garden, and take advantage of your garden as a place to relax that you haven't experienced before. 

The Palram Oasis comes in anthracite grey, a deep shade that gives the Oasis a look of precision and evokes contemporary architecture. 


The structure of the Palram 12ft Oasis relies on durable materials, providing a strong foundation for the greenhouse. This begins with a galvanised steel base around the perimeter of the Oasis, which improves stability and is resistant to corrosion. Sturdy aluminium is used for the rest of the greenhouse's frame and has an attractive grey powder-coated finish. 

The finishing touch is the high-quality polycarbonate glazing. Frosted twin-wall glazing is featured in the roof panels to diffuse the harshest light from the sun, while the glazing featured in the walls is crystal clear. This makes the interior of the Oasis an appealing place to sit and relax in mild weather, with the clear side glazing giving you a good view of your surroundings. Looking into your Oasis from the outside, the transparent sides bring clarity to your hard work on the plants inside.

If you want to create a sustainable irrigation system for your plants, the guttering that comes built into the Oasis's frame means that collecting rainwater in a water butt is a straightforward task. As is controlling the temperature and humidity of your greenhouse, thanks to two elegant louvre vents that can be manually opened to let in fresh air.

A low threshold doorway ramp and double doors that open wide mean that accessing your greenhouse has never been easier. The generous headroom of the Oasis is often remarked upon by visitors, too, with an interior height of over eight and a half feet at its peak.


Hobby gardeners will appreciate the opportunities Palram creates to expand the uses of the Oasis and extract its full potential with its range of accessories. Make adjusting the louvre vents you have an easy experience with the Automatic Louvre Vent Opener. This item requires no external power and instead relies on the sun's warmth to expand a hidden wax cylinder and push open the vent. As the ambient temperature cools, this works in reverse when the piston contracts and draws the vent shut to the elements.

To make the most of the generous height of the 12ft Oasis, we recommend investing in a Trellising Kit Pro. This item includes everything you need to care for plants with tall and frail stems that need support – six roller hooks, twine, and three types of support clips for various crops. 

Additional Details
