Frequently Asked Questions


If the building is shorter than 2.5m tall you should not require planning permission, (unless it’s more than 50% of your garden or to be put in your front garden). Planning permission rules can vary by area so we would strongly recommend checking your local council rules before ordering from us.
We'd recommend any flat and level base be put in place before you start construction of any of our buildings. The material can vary so long as it creates a flat and level base, many cutomers opt for Concrete, Paving Slabs or our popular Ecobase and EzeBase options available above. The floor of the building comes with bearers which lift the building off the base and allows the flooring to have a gap between itself and the ground this helps slow down or stop any rotting that could occur if the wood is kept in standing water.
The building should be treated once fully assembled and within one month of recieveing the product. All the treatments we supply ensure the building will only need to be treated once a year, but always consult the directions on the treatment that you have purchased. Pressure treated building dont need to be treated annually but may need to be topped up in its later life.

More About the Switch Wooden Apex Greenhouse...

The Switch Apex is a wooden greenhouse with the modern features to take your growing to the next level. Carefully designed to culture great growth while staying strong against the elements, the Switch Greenhouse checks all the boxes.

Ideal Growing Environment 

The interior Switch is surrounded by an exterior wall of floor-to-ceiling styrene glazing panels. These panels provide all-around sunlight exposure, meaning no matter where it is in your garden - and no matter where the sun is in the sky - the greenhouse will be getting light (as long as there’s nothing in the way!). The Styrene also provides a level of insulation, keeping your plants cosy during cool nights.

Apex Greenhouse Roof 

The Apex roof of the Switch not only creates an endearing, classic silhouette, it also comes equipped with useful features to assist your growing efforts. The channelled polycarbonate glazing provides ideal levels of light exposure, enough for growth but not too much to do harm. Meanwhile the opening roof vents let you naturally circulate air through the interior.

Space For Planting 

No matter the scale of your growing project, the Switch can match it. A range of five sizes are available to pick from, meaning you’ll get a greenhouse that suits your requirements. Finding the right room to grow isn’t just easy, it can be built-in too with our additional planting tables!

Timber That’s Designed to Last

Strength is a given with the thick tongue and groove cladding and extra-thick framing that provides the shell of the greenhouse. What’s better is that all the wood used in the Switch Greenhouse is pressure treated, conserving the quality of the wood for longer. For additional peace of mind, the building comes with an incredible 15 year guarantee that protects against rot, decay and insect infestation.
