Everyone is talking about energy efficient design and how this makes your home more comfortable to live in and cheaper to run. But do you know the importance building orientation plays in this?

Orientation refers to the placement and positioning of your granny flat in your backyard.  Good orientation will take in to consideration the local climate and seasonal sun and wind variations.

Poor orientation often occurs when a standard design is picked out of a brochure without any consideration given to the individual property and surrounds on which it will be built.

This is just another reason why we custom design all our projects at Perth’s Granny Flat Specialist.  A well thought out floor plan can save you thousands in unnecessary insulation, glazing upgrades, and long term heating and cooling costs.


One of the first steps in our process is carrying out a site assessment.  The company Director, Shane, will come to your property to see and listen to what you’re trying to achieve.  This also gives him the opportunity to answer questions such as… Does your backyard have large shady trees? Which side of the property does the sun rise?  Do your neighbours have a double storey house?  Do you get strong easterly winds or maybe a sea breeze?  Are you located on a hill?  Which direction does your existing house face?

What are some of our top tips for an energy efficient orientation?  In Perth we try to have:

  1. The longest walls (surface area) on the northern and southern sides.
  2. Kitchens and living spaces on the northern side.
  3. Bathrooms, laundries and rooms used less frequently on the eastern or western sides.

The building should be orientated to maximise sun exposure in the winter but minimise exposure in the summer.  Building setbacks also need to be considered to utilise natural light and air flow.
