Shadehouse Tunnelhouses

Redpath aluminium Shadehouses are one of NZ’s most popular and we have supplied many 1000’s to happy home gardeners, lifestylers, schools & institutions nationwide.
Compare the size of our sturdy 32mm square aluminium hoops and four 25mm square purlin rails which give excellent strength and durability. Search Redpath Greenhouses on YouTube for our latest assembly videos. The main frame and base rails are 100% aluminium with no timber to rot, rust or to taint soils from tanalising.
Our frames include an integrated groove to reliably fasten the covering and easily allow you to use different types of coverings if required. The latest Mk2 design has an simpler and speedier to use “V Lock” cover holding system. Redpath’s tall 2.3m apex height gives plenty of height for crops and gives increased internal air volume to act as a temperature buffer and frost protector. Our Shadehouses use 30% white shade cloth for the covering which has a 10 year + service life. You can personalise your shadehouse with many optional extras to ensure your shadehouse matches your location and your crop growing needs.
A rear wall door may also be fitted as an option.  A wider 830mm ‘Wheelchair / Wheelbarrow” door is an option at either end. Sidewall or rear wall shelves are an option. You can also add a wind kit upgrade for modest cost if your site is a little more exposed, The wind kit adds extra Sidewall braces, Collar tie cross braces and reinforced hoop feet. A custom sized raised garden are made for the tunnelhouses – lengths are 1.4m, 2.8m and 4.4m. You can add as many gardens as you wish end-to-end to fit longer tunnels, and can also include an optional internal liner to act as a barrier between the stabilised timber and the soil. Overhead full length aluminium crop support rail(s) can also be added for tying your plant support strings/wires too. 
Redpath has been a trusted NZ brand for 45 years, and to compete with a multitude of often low quality imported designs we now sell to you direct.  This ensures you get a great quality product at a great price. We include a NZ factory warranty, and full parts back-up service. To make assembly speedier we deliver the shadehouse to you up to 50% pre-assembled (see images above of a tunnel being collected to show work pre-done)
