Sustainable, or green building can be many things to many people – there’s so many options available. Here’s some key considerations when building…

What is a Sustainable Home?

It can be a confusing term as it encompasses a variety of things, some of them obscure but many that are becoming part of good practice. The usual points considered with a sustainable home are:

  • the energy and materials used in construction and the building’s impact on its environment
  • the lifespan of the building
  • the building’s design in terms of heating cooling, lighting and water usage.


There’s a wide choice of materials that can be used in the construction of a home and all come with different environmental “costs”. If this is something you’re interested in it’s worth you doing some research on the subject as it is wide and varied. Rolfe Constructions will certainly do all we can to work with you when considering the efficiency of your build or renovation.


Ideally you want to build a home that can adapt to your changing lifestyle as time goes on. A home that can easily be updated or extended as needed. When designing a new home it’s important to not just think of the here and now. Perhaps you currently have a young family and want a home designed around them, but you should also look down the track. How are your requirements going to change as your children grow? And as you age? Do you plan to stay in the house through to retirement age? Or should you also be considering resale? By being clever with your initial design you can ensure that you have a home that evolves over time without significant renovation or rebuilding.

Passive design

A well designed and well built home will mean you pay much less to run your home and maintain your comfort. Heating and cooling are well worth serious thought given our climate. For example, the orientation of your house can have a huge impact on heating and cooling by harnessing the sun’s heat effectively for warmth and light, and creating shade for cooling. For any indoor climate adjustment you also need a good, tight build to ensure excellent insulation. Heating and cooling your home can be extremely energy-intense if your design and build are working against your best efforts. The list of other considerations to create a passive home are almost endless – rain tanks, solar panels, composting toilets … There are a million ways to improve the way your home functions.

Why build a sustainable home?

Building a sustainable home does usually mean more out-of-pocket in the short-term, but with some fairly simple considerations you can create a home that is cheaper to run and will suit your needs for longer. This can mean significant savings in operational costs and any ongoing modification plus a bit extra in resale value.
