When you are looking for a tunnel house it is important to make sure it is well constructed and that the plastic film is held securely if you want it to last. We looked at a lot of tunnel houses before deciding on these ones and these are the reasons why:

Our 2.4m wide Tunnel Houses are made of a corrosion-resistant aluminium frames spacedat 1 metre intervals to give extra cover support. Some other brands have 1.5m spacing.The picture to the right shows a 6m tunnelhouse.

Special thermal insulating tape (just like with our larger polytunnels) is applied to the frame where it meets the cover to prevent the plastic being cooked at these points. These refinements add a small amount to the cost, but we think it is worth it, as it results in a longer cover life and ultimately a big saving to the owner over time.

Equally important is how it is constructed. The aluminium hoops fit into predrilled holes in the H4 timber base. The base is held to the ground with wooden pegs that are hammered into solid ground. The pegs are then are nailed to the base. If you have soft ground or experience high winds we would recommend you concrete in the pegs with some under-cut. The cover is held by a rebate and wooden lock strip nailed to the base.

Our tunnel houses are supplied direct to your door in boxed kitset form. The complete kitset includes a H4 treated timber base, H4 wooden pegs, fastenings (nails screws etc), aluminum frame, one sliding entry door (can be assembled to open left or right), vents as per the table below, frame tape and a machine welded commercial grade plastic cover.

All you will need are some simple tools. Hammer, Screwdriver, Tape Measure, Sharp Knife or Scissors, Heavy Hammer or Mallet, Petroleum Jelly or Grease for the top door track slides.
Warranty. The aluminium frame and wooden base is guaranteed to be free from defects and manufacturing faults for a period of one year.

The cover is guaranteed in N.Z. for four seasons (48 months) against breakdown by U.V. degradation. If U.V. breakdown occurs and is confirmed by the manufacturer's sample analysis, a pro rata replacement credit will be allowed. A credit will be issued, based on original invoiced value, for the unused period of the Warranty. Warranty is to the original purchaser of the tunnel house.

Our experience is that the cover lasts at least 10 years if you look after it.

Please note: Whilst our tunnel houses are very strong this does not mean you can put your tunnel house up in an exposed situation and expect it to survive gale force winds. They are designed as a domestic tunnel house. Common sense needs to be exercised and adequate shelter provided. Permeable wind breaks are recommended in exposed situations. The guarantee on the frame and cover does not cover mechanical damage, including premature damage caused by chemical use, high winds, weather conditions or extremes of temperature.

Where breakdown has occurred on frames or pipes, warranty is conditional upon frame tape being used to protect the film from heat build up on the frame.

Replacement covers.

Please note our covers are specifically made for our tunnel houses. This means that if you have another make it may not fit or may not tighten up. If you have an old tunnel house and you don't know if it is one of ours or not it is easy. Are the hoop spacings at 1 metre intervals and does it have frame tape on the hoops? If yes then it is probably one of ours.
