Wondering how easy our Easy-Build really is? 

Tony from Simplify Gardening built a Northern Polytunnels Easy-Build and here is the great, easy to follow video.

He also did a follow up video 6 months later, which you can watch here:

Or click each heading below for even more reasons why Northern Polytunnels build the best.


By far the best and most popular method. Suitable with most soil types, especially clay soils.  Avoid only on ground with a high stone/rubble content, peat soils, or loose soil that has been recently disturbed or deep cultivated.

Each screw anchors only takes 1-2 minutes to screw into the ground. Compare this to the time it takes to dig each hole when using either the concreting method or ground anchor plates, and without any of the mess or exertion.


In recent tests, we measured the strengths of different polytunnel foundation options.  The tests showed that our screw anchors outperformed all other methods in most types of soil.  A close second place was traditional foundation tubes when concreted in position.  In third place, trailing a long way behind, was the use of ground anchor plates (sometimes called ground anchors).  They simply didn’t come anywhere close to the other two methods.  To give you some idea of the difference, we compared our screw anchors to one of our competitor’s heavy-duty ground plate kits and found that it took four times more force to pull our screw anchors out of the ground. 

Our aluminium base rails, doors and door frames all incorporate our unique ‘W-Wire’ polythene securing system.  Simply weave the ‘W-Wire’ into the open channel of the aluminium rails & frames, securely trapping the polythene in place.  Don’t worry if you need to redo a section, it’s easily unclipped and can be ‘wiggled’ back in to place in a jiffy, ensuring a tight, neat finish every time! 

Wiggle wire

This is especially useful when pleating the polythene around the door frames.  For those of you who have previously used timber rails you’ll already know how difficult it is to fasten polythene using wooden laths/battens - trying to pull the polythene tight whilst holding a lath in place, positioning the nails, and finally hammering them home, and all with only one pair of hands.  ‘W-Wire’ is the easiest and quickest system on the market and doesn’t require any specialist tools.

Hoops that are made from three or four pieces are easier to make and more convenient to deliver, however, they are not as strong as a two piece hoop and often require extra bracing bars to support them.  That is why we only make two-piece hoops, and one of the reasons why we sell so many polytunnels to customers in the Scottish Highlands and Islands. 

Steel Hoops

All our steel tube is construction grade Z35 that is galvanised both inside and out.  It is 32mm in diameter with a 1.5mm wall thickness.  

NOTE: Watch out for other manufacturers who use 25mm or 28mm tube, and sometimes with only a 1.2mm wall thickness (20% thinner).

Due to the natural variances which occur in timber, and it’s much shorter lifespan, we now only use aluminium for our base rails, doors and door frames.  Aluminium is free from defects (such as knots, splits etc.) and will last a lifetime, unlike treated timber which has a lifespan of around 15 years.  

All the fixtures and fittings are simple to attach and allow a little room for adjustment if required.  Every piece of aluminium is cut precisely to length, removing the need to trim off any excess. 

Our single door frames have a 0.8mtr opening. The double door frames have a 1.7mtr opening.  Due to the extra width of a double door frame they are only available for 12ft (3.66m) and 14ft (4.27m) wide polytunnels.  The height of the door lintel is approx. 2mtr.

Aluminium Sliding Doors: Made from easy-to-assemble aluminium sections incorporating our unique ‘W-Wire’ polythene fixing system.  Supplied with enough materials to fully clad it with polythene, or to clad the top half with netting for extra ventilation. 

Aluminum Doors

PVC Ventilation Panels: Fabricated from translucent PVC fabric with a PVC mesh insert.  Comes with a removable translucent PVC fabric panel which simply attaches over the mesh (to seal the vent) with its Velcro edging.  Can be fully opened, fully closed or partially opened.  Gives ventilation without allowing unwanted pests to enter your polytunnel.  Quick and easy to fit. Only available with single door frames and only one per structure as this option isn’t used for access.

Our new Hobby Plus - Easy-Build polytunnel not only comes with a comprehensive set of instructions, there is also an in-depth instruction video which can be viewed below
