Optimal House Orientation in Adelaide: More Than Just Facing North

Understanding the Best Orientation for a Home

When it comes to building a house in Adelaide, the conventional wisdom suggests that facing a home north is the ideal orientation. However, this is not always the case. The shape of a block and the type of home you intend to build are crucial factors that influence the best orientation for a specific situation. By choosing the right orientation for a home, you can reduce costs and enhance comfort.

Factors Influencing House Orientation

The Importance of the Block Shape

The shape and size of a block significantly impact the optimal orientation of a house. For instance, if you have a deep and narrow block, you may be forced to use a different home layout than if you have a wide fronted block. The wider the frontage, the more flexibility you have in designing a home with either large windows facing the street or a patio at the back. However wider frontages tend to be more expensive, regardless of whether it is an infill development or a greenfield site.

The Type of Home You Want to Build

The design and layout of a home also play a pivotal role in determining the best orientation. If your house design includes large windows facing the street, a north-facing block may be optimal as it allows for passive solar heating and natural light. However, if you prefer large windows overlooking a backyard patio, a south-facing block might be more suitable. If the block faces south the main windows can face north and open onto the back yard giving a very pleasant aspect.

Window Orientation Over Block Orientation

While the block's orientation is important, it is through how it influences the shape of a house and orientation of the windows and is not inherently important by itself. The placement and size of the windows will determine how much natural light and heat a home receives. For example, if a home has large windows on the front façade and you are building on a wide-fronted block, a north-facing block will maximize sunlight. On the other hand, if the main living areas have large windows facing the backyard, a south-facing block will provide a more comfortable living environment.

Deep Blocks and Side Windows

Narrow, but deep blocks present a different set of challenges and opportunities. If the block is deep, you may need to place more windows on the sides of the house to ensure adequate natural light and ventilation. In this case, an east or west-facing block may be the best option. The side windows should ideally primarily face north and give you an opportunity to have a northern courtyard which will be pleasant in summer and winter. 

Challenging Traditional Notions

Traditionally, west-facing blocks are considered the least desirable due to the intense heat from the afternoon sun. However, this orientation can be advantageous if the front façade of your home is largely a garage. The garage can act as a buffer, protecting the living areas from the harshest sunlight and reducing cooling costs. The garage most importantly reduces the area of windows facing west and hence reduces the building cost required to keep the summer heat out.

Maximizing Comfort and Efficiency

By carefully considering the orientation of the house and windows, you can maximize comfort and efficiency. A well-oriented home will take advantage of natural light, reduce reliance on artificial heating and cooling and create a more pleasant living environment.

Reducing Construction Costs

Choosing the right orientation can also help reduce construction costs. Properly oriented homes require lower cost windows and window treatments, costing less to construct a 7-star home This can lead to significant savings during the construction process and greater comfort and more light in the home.

Conclusion

In conclusion, while north-facing homes are often idealized, the best orientation for your house in Adelaide is not a one-size-fits-all solution. It depends on the shape of your block, the type of home you want to build, and the placement of your windows. By thoughtfully considering these factors, you can create a home that is comfortable, efficient, and cost-effective. Whether you have a wide-fronted block, a deep block, or a narrow block, there is an optimal orientation that will suit your needs and preferences. Embrace the flexibility and design a home that truly works for you and your lifestyle.
