Use of 50mm & 60mm pre-galvanised steel tube, heavy duty foundation tubes, two-piece hoops, extra strong windbreak mesh
Our unique cover tensioning design allows the hoops to be raised and locked after cover fitting, creating a drum-skin tight finish for better durability in severe weather
Single-span structures offer superior ventilation which is beneficial for livestock health. Also linked benefits: reduced bedding costs, lower incidence of twin-lamb disease, improved welfare, lower mortality
Wider tunnels reduce “lost” livestock space when including a central passage resulting in an efficient use of space.
Designed and manufactured in the UK by Northern Polytunnels. Full service: consultation, bespoke design. Aftercare & maintenance support.
Use of natural light reduces energy / lighting needs. Shortwave radiation warms & dries, reducing bedding cost. Warmer environment helps feed conversion ratio, lower feed cost
A polyhouse is ideal for flocks of any size and is particularly well-suited to upland or hill farms where flat ground is scarce. Single-span structures also offer superior ventilation, improving livestock health and welfare.
Wider tunnels reduce the cost per square metre and make layouts more efficient. For example, our 9.15m (30ft) wide tunnel is the most economical choice: with a 3m central feed passage, only around one-third of housing space is lost. By comparison, a 6.4m (21ft) tunnel with the same passage would lose nearly half. Choosing the right width can have a major impact on efficiency and cost-effectiveness.
As well as winter housing many customers use polytunnels for general storage as well as a dry place to house sheep before and during sheering, making them a year-round investment. They are becoming increasingly popular as calf housing and poultry sheds, as well as housing for dairy herds, beef cows, goats and pigs.

When planning your sheep housing, the right layout makes a big difference to animal welfare and cost efficiency.
💡Pro Tip: Wider tunnels don’t just save space — they also reduce cost per square metre, making them the most economical option for larger flocks.
⭐ Golden Rule: Space for feed access is more critical than overall lying area, it prevents stress and ensures every ewe gets the nutrition she needs.
Prioritise forage face and trough space over overall area — every ewe must access feed without competition.
Install water bowls/troughs where they’re less likely to foul or freeze.
Position feed troughs for easy removal of waste feed and regular cleaning.
Separate lame or sick ewes into a hospital pen to give them special care and prevent disease spread.
Provide enough space during lambing for lying and feeding — overcrowding increases stress, disease risk, and welfare problems.
Set up pens for efficient cleaning, stock handling, and smooth movement of sheep.
