INTEGRATED SUSTAINABLE  SOLUTIONS

Our passion for sustainability extends to our product sourcing and system designs. If you're interested in reducing your environmental impact, we can provide 'whole house' integrated solutions, incorporating all aspects of plumbing, heating and energy. It's not just for new builds - these products can often be retrofitted and can be used individually or in conjunction with a number of options depending on your preferences.

There are also many other factors consider in your design, including building materials, insulation, thermal mass, ventilation, appliances and fixtures/fittings. Many architects and designers are now specialising in passive, low environmental impact house designs.

It doesn't need to be complicated, we're here to help you out - every step is a step in the right direction.
