Do you want to build a smart eco-effective home that doesn't cost the earth?

Are you increasingly mindful of the impact that our homes have on climate change and the environment? Do you want to design a new home or renovation that makes a positive contribution, not just minimises harm?

Then you’ve come to the right place!


Sid Thoo is an award-winning architect, educator and consultant who can help you design a quality eco-effective home that is more sustainable and won't cost a fortune.

I help all kinds of people design and build homes and buildings that are environmentally, socially and economically more sustainable. Sustainability is a word that gets used (and abused) more often than not, so I tend to describe the work I do as eco-effective.


I am privileged to practise primarily on Whadjuk noongar boodjar and acknowledge the traditional owners of this country. I also support an Indigenous Voice to Parliament.

Needless to say, my clients and I were very excited to be selected for this opportunity.
