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.


The 8x4 Lean To Clear is an aesthetically pleasing and highly functional greenhouse structure for allowing you to excel at gardening projects, whether that means protecting plants in frosty winter months or nurturing new seedlings.

This growhouse has exciting potential for hobbyists who want to get a lot out of a very limited outdoor space. As long as there is access to a stable 90 degree wall and the room to attach your Lean To, the product shines in small gardens, larger balconies, or courtyards. Its endearing scale and great functionality means the Lean To will immediately become a treasured feature of any garden. Any hobby gardener not yet ready to commit to the scale of a freestanding greenhouse will therefore find the Palram Lean To an exceptional alternative.


This 8x4 Lean To features clear polycarbonate glazing that makes it ideal for showing off your plants to any onlookers and keeping a close eye on their progress. The material is lightweight and thin but virtually unbreakable, and is resistant to discolouration and clouding over time. Because of this, polycarbonate panels are an excellent finishing touch to the solid aluminium structure attached to a galvanised steel base.

An adjustable vent window on the Lean To's upper panels adds some further versatility to your growing area. Combined with the hinged single door, the vent provides adequate means for reducing the heat and humidity that can build up within your greenhouse on scorching summer days.

Another handy feature brought over from Palram's other greenhouses is the built-in guttering system. This collects any rain that falls onto the Lean To's roof panel and diverts it for easy collection in a water butt or other container.


Palram's expertise in putting together garden structures that are highly practical extends to their range of accessories. Despite the more limited options of a smaller structure like the 8x4 Lean To, we recommend adding the Two Tier Staging to your order. This unit features two shelves that cumulatively hold up to 200kg in weight (upper shelf up to 160kg, lower shelf up to 40kg), assuring a stable platform for any pots or tools. The staging makes a great add-on for your Lean To because it can double your potential growing space by stacking your plants, and allows excess water to drain away.

For those gardeners to whom efficiency is key, a Drip Irrigation Kit can be exceptionally useful for watering thirsty plants without needing to access them with a watering can. The piping that comes with the kit can be cut down to tidily fit your setup, and the droppers provide a filtered and steady stream of water.

Additional Information

The 8x4 Lean To requires a stable 90 degree wall to be mounted against. Assembling the Lean To is made simple with the manufacturer's written instructions. Once the galvanised steel base is in place, the aluminium frame will soon come together and the polycarbonate panels finally slot in place. Customers find the assembly process takes a day, or several hours for more DIY-minded types. Once assembled, enjoy the fact that your Lean To requires little maintenance, thanks to an aluminium frame that is corrosion-free and a secure galvanised steel base.

Be secure in the knowledge that your Palram greenhouse will be covered by the same five-year warranty that is offered for every product in the range. Check the manufacturer's instructions regarding the coverage to ensure you have the full details with respect to the minimal maintenance and care needed to make sure this warranty is valid.
