HK Perma Club is a permaculture focused club promoting a sustainable lifestyle through design and infrastructure. They offer workshops, volunteer days, team building activities, school days for kids and you can rent the site as a venue for events. They are open every day except public holidays. 

Volunteer groups happen every second Sunday via Meetup to explore organic farming, composting, recycling and water management.

The site is located in the valley below the road.
