The CoolHouse™ is a greenhouse system sustainably generating its own fresh water and providing optimum growing conditions inside a protected structure.

Coolhouse takes longer to build than an EcoPolyTunnel, however, it offers a number of distinct advantages over the EcoPolyTunnel including:

  • Structures can be much larger
  • Greater temperature control range
  • Seawater desalination 


Key benefits include: 

  • Creating ideal growing conditions – reducing the internal temperature by as much as 12°c
  • Environmental sustainability – Low Carbon Low Energy
  • Production of freshwater for crop irrigation
  • Rainwater harvesting
  • Optimum growing conditions 365 days a year

The CoolHouse has the ability to reduce a 30°c ambient by as much as 12°c making it ideally suited for the Tropics.  Its modular design can be customised to produce a wide variety of fruits, vegetables, flowers etc. each cluster easily adapted to suit small to large-scale growers.

The CoolHouse performs at its best within 5 kilometres of the sea; a Certificate of Environmental Clearance and Town & Country Planning permission is required.


10 x CoolHouse = CoolHouse Cluster:

Minimum Unit Size 9.144 x 33m (30’ x 108’)

Minimum Overall Size from 3,017.5m2 (32,400ft2) Approx. 0.74ac2 (0.3he2)


These units can easily be double the size stated above and therefore covers serval acres when clustered to produce higher tonnage yields of crops per acre than our EPTCs.  However they require more investment in equipment and management for operation.


With greater mechanisation these clusters are estimated to produce over 200 tons of tomatoes per acre per week and with a larger number of employees required makes this the ideal setup for generating employment and down streaming of clustered development within the food production, processing, haulage and many other industries.
