Adelaide climate design
Do You Need Eaves on Your Adelaide Home?
Modern Adelaide home designs sometimes skip eaves for a sharper look. On a north-facing wall in this climate, skipping eaves is almost always a mistake. On other elevations, it depends. Here is how to think about it wall by wall.
Public source: Your Home: shadingSection 1
What eaves do
Eaves shade windows and walls from high-angle sun without blocking low-angle sun. They also protect wall materials from weather (rain running down a wall vs rain shed away from a wall matters for both durability and maintenance).
Section 2
North eaves: near-mandatory
A north-facing eave depth of around 450mm to 700mm shades most of the summer sun off a standard 2400mm-high window while admitting most of the winter sun. Skip north eaves and the summer sun cooks the living areas exactly when you can least afford it.
Section 3
East and west eaves: they help but do not solve
East and west sun in Adelaide summer comes in low (before 10am and after 3pm). A standard eave cannot shade a low-angle sun. You need vertical shading (external shutters, awnings, wing walls, deep verandahs, or thick landscaping) as well. Skipping eaves on east and west is less of a comfort problem than skipping them on north, but it is worse for weather protection.
Section 4
South eaves: least critical for sun
South-facing walls barely get direct sun in Adelaide. Eaves on the south are more about rain protection and roof detailing than solar control. Skipping south eaves for a design reason is defensible.
Section 5
Eaves and rain
Adelaide has a long dry summer and a wet winter concentrated in a few months. Homes without eaves see accelerated staining and material degradation on walls, and windows get more direct rain onto their seals. Modern rendered facades still perform, but they will show wear faster than an eaved wall.
Section 6
If you want a "modern" no-eaves look
Use it selectively on the front elevation for street appeal. Keep the north and rear elevations properly eaved for comfort and performance. Most Adelaide designers can give you the sharp street look and the performant private side of the home in the same design.
