2.35m x 4.0m Timber Base Tunnel House — Built for NZ Conditions

A tried and true Kiwi design that's been supplying home gardeners, lifestylers, schools, kindergartens, restaurants, nurseries, and maraes nationwide since 1980. Built to last, easy to assemble, and shipped direct to your door.

Why Choose a Timber Base Tunnel House?

  • H4 Tanalised Pinus timber base — sturdy yet lightweight, easy to build and move into place, or incorporate into a raised garden bed for a seamless look
  • Pre-drilled holes — in both the timber base and aluminium hoops for fast, simple, and accurate assembly
  • Polygro 200 micron greenhouse film — prefabricated as one piece for an excellent fit, minimal wrinkles, and no seams to secure
  • Exceptional PAR light transmission — superior light levels during the day and locks in night-time temperatures for consistency
  • All-weather protection — strong against wind, hail, and snow. We recommend a little shelter from the prevailing wind for exposed sites
  • Full instructions + instructional video supplied

What's Included

  • Aluminium hoops
  • H4 Tanalised Pinus timber base
  • Polygro 200 micron prefabricated greenhouse film cover
  • Wooden battens for securing the cover
  • Roof vent
