Join Willesden barn open day. Walk the first New Zealand laminated timber barn.
Get insights on 1,000 cow dairy conversion done right, how to winter in a composting barn and what ROI to expect.
Willesden Farms has turned 300 hectares into a dairy operation, milking 700 cows this season. The pivot hinges on a new composting barn that slashes the farm’s environmental footprint by 46%. This eco-friendly alternative to steel-framed barns is up to 20% more cost-effective than traditional builds. It handles moisture in effluent-heavy settings without corroding.
