WHEN it comes to housing and garlic, good design is more important than hard work. In both cases, the core decisions that ensure quality can be counted on one hand. Everything else are details.
In the case of housing, we can look around the world and observe examples of low energy and high performance homes. For the most part, the design principles are universal with the exception of the tropics where important tweaks must be made compared to other regions.
For example, the main goal of good tropical house design is passive cooling that relies on cross ventilation. From this perspective, homes should be rectangular with the long axis running north-south to catch breezes. For almost all other locations around the planet a home should be rectangular with the long axis running east-west to catch the winter sun and exclude the summer sun. In all cases the basic design objective is a passive structure that heats and cools itself as much as possible using natural energy flows.
Beyond passive design, another wise choice to make with housing is to place fixed heaters on internal walls rather than external walls. Placing a heater close to the centre of a home and surrounding it by living spaces would appear to be common sense until you take a trip around Whanganui and see the preponderance of chimneys built on one extreme end of long rectangular and L-shaped homes. It appears there was an era in our city where common sense and good design were sorely lacking when it came to home building. Some would argue it continues.
Fixing bad design is more expensive than engaging good design from the start, but the good news is that in Whanganui it is far more affordable to buy an existing home and do it up rather than build a new home. For example, our renovated villa ticks the boxes for good design for less than half the cost of building new.
