We are all about:

  • Sustainable building that is environmentally responsible and resource-efficient throughout a buildings life-cycle
  • Expanding and complimenting the classical building design concerns of economy, utility, durability and comfort
  • Designing buildings that reduce the overall impact of the built environment on human health and the natural environment
  • Bringing energy efficient and environmentally friendly construction practices to life
  • The environmental, economic and social benefits of good “green” design solutions


We understand that:

  • With proper synergistic design, individual green building technologies work together to produce a greater cumulative effect
  • The needs of a design can be achieved without compromising the ability of future generations to meet their needs
  • Renewable technologies are constantly evolving and the designs must take this into account
  • The objective is to minimize the total environmental impact associated with all life-cycle stages of the building project.
  • Buildings are complex products each comprising of a multitude of materials and components with every design variable and variation affecting the environment during the buildings relevant life-cycle.
