who we are

Hi, I’m Adrian Fratelle, Director of Ecohabit. I started working in the industry in the early nineties when I took a job as a designer in the residential building industry. I quickly realised, however, that I wasn’t satisfied with the homes the market was producing.

Most were built with brick or concrete, with large air-conditioners and far too many down lights to compensate for their inefficient design. So, after only two years in the industry as a designer, I knew I wanted to create something different.

I wanted to architecturally design liveable homes, with an eco-edge – something that wasn’t happening in Perth’s market.

That’s when I first started designing energy efficient homes. Several years later I decided to further my studies to become a builder and started working on-site as a tradesman and supervisor. During this time I continued designing homes.

Clients saw the benefit of my on-site experience coupled with my willingness to design homes that were different. With each new design I began to get a reputation for designing homes that “worked”. They were practical, not oversized and, most of all, comfortable. Before I knew it, I was designing so many energy-efficient homes that I downed the tools and started designing full-time.

what we believe

We should all try a new EcoHabit

The word ecohabit is a derivative of two words, ecology and habit. Ecology is the study of organisms and their interaction with their environment. Habit is a word we are all more familiar with. It means an acquired pattern of behaviour. Therefore, an ecohabit is a habit formed between our interaction with each other and the environment.

Many of us think that our environment is our land, our forests, our country or our planet. This can make it overwhelming to consider how we can take care of our environment; the earth is large and filled with billions of people after all. But our environment actually starts at the tip of our nose. It’s at our desks, our houses and the yards around it. By taking care of this environment first we’re playing an important role in taking care of the environment that is our entire earth.

Right here at my desk I have a paper-recycling tray. That’s my first ecohabit! I walk to work whenever I can. My second ecohabit. These are some very simple ways to start creating a sustainable way of life.

Let’s take it up a notch. Say I’m renovating and extending my home. Straight away, by maintaining some of the original structure I’m reducing landfill and conserving energy as the building does not need to be demolished and removed. I have decided that the new building will be timber framed, slab on ground with good northern aspect to the living areas.

The timber framing is lightweight plantation pine so it’s a renewable resource and has comparatively minimal impact on the environment. My concrete slab will be polished, exposed to northern winter sunlight and will provide my home with great thermal mass. Combine that with well-insulated walls and ceilings so I won’t need to run a heater during winter or air-conditioner in summer. Now that’s a good ecohabit that will also save money!

With a bit of knowledge and some good habits we can start to create a sustainable environment for our families and ourselves. Many of these will be cheaper or won’t even cost a thing. For example, try walking to work, or catching public transport.

Other habits may cost nothing over and above what we’re already paying. Like changing a blown halogen light globe to an LED energy saver globe, or having your home designed to be solar passive to reduce energy consumption and improve your lifestyle.

At Ecohabit we’ll consider how we can seamlessly introduce new ecohabits into your lifestyle while designing your home. Call us today and arrange a free consultation to discuss how, together, we can create you and your family a new lifestyle full of good ecohabits.
