A 12ft wide polytunnel will easily allow you to have one central bed and a further growing bed on each side - a layout that can really maximise the use of space while making it easy for the gardener to get around. If you are taking the next step on your journey towards a more sustainable way of life then a 12ft polytunnel could be perfect - big enough to grow a quantity of food but not so big that it becomes overwhelming in a domestic setting, on an allotment or in a community garden.
Check out 'What's in the Kit' to find out exactly what is included in your purchase of a 12ft wide polytunnel, then scoot on over to our accessories sections to see what added extras you may wish to include.

Even better - the more extras you include, the more you can save with our fantastic bonus save offers. Just pop everything in your basket to find out how much you can save on your ideal 12ft wide polytunnel.
The 12ft (3.66m) wide Polytunnel is another very popular Domestic option, ideal for the larger garden or allotment. On this width the straight sides give you ample room for staging, increasing your growing potential no end. Like all of our Domestic models, it comes with 'real' doors at each end, ensuring good air circulation.

We have four construction guides for our 12ft Wide Polytunnel Model.
12TR/12STR for polytunnels who require the cover to be buried in a trench. 12BR/12SBR for polytunnels that have Base Rails eliminating the requirement for digging a trench. The 'S' denotes whether the Polytunnel has been upgraded to 35mm Hoops.

We haven’t stopped there, we know many people build their polytunnels at the weekend or over a bank holiday when our office is closed, so we have also produced a series of Polytunnel Construction Videos. This collection of videos can be viewed anytime, on your home computer, and even your phone for when you are in the thick of things constructing your polytunnel.
We supply Timber Hinged Doors at each end, Anti Hot Spot Tape, Timber Base Rails and of course the Framework to support our 200 micron Super Therm Polythene cover. These options are pre-selected below, but can be amended to suit your needs.
You will be required to secure the foundations into concrete, alternative methods of securing the polytunnel can be selected, eliminating the requirement of concrete – see ‘Polytunnel Foundation’ section.
