About

We specialise in environmentally sustainable and ethical architecture including residential, and small scale public and commercial buildings.

Our practice has been based in Hobart for over twenty years,
and we love Tasmania and the particular challenges our climate poses.

We can now quantify the embodied carbon in any building and are proud to say we know we can design True Carbon Zero buildings! This means they are not only operationally carbon zero (all energy use in the building throughout the year is covered by renewable power, usually rooftop solar), but also all embodied energy is paid back into the grid in renewable power. Our studio is one such example. We aim to make all buildings we design carbon neutral by 2050.

Some of the design principles our practice uses are:

  • energy efficiency through passive solar design and effective insulation (for thermal comfort, low carbon footprint and minimal running costs)
  • low embodied energy
  • low impact on the site
  • sensitivity to the unique aspects of the site, views and the local landscape
  • water conservation
  • healthy and ethically sourced building materials
  • high quality construction and finishes
  • design for future flexibility, climate change resilience, longevity and low maintenance
  • low entropy for easy demounting and re-use/recycling

Our houses are generally over 8 stars, an optimum for energy efficiency and economy. We design passive houses and enjoy implementing designs which need hardly any heating or cooling.

Our in-house energy expert uses energy rating tools, to forecast the home’s heating requirements and increase the performance.

3D modelling software allows clients to explore our buildings before the finished product - no building should be a surprise for the owner when it is being built. We can also model sun penetration any time of day and year, views from particular windows etc.

Our projects enhance the site conditions and values and are an expression of their owner’s values and ambitions.
We listen to our clients. And we love our work.

We acknowledge the Traditional Custodians of the lands on which we work. We pay our respects to the elders of the palawa and pakana people.
