Eaves

If you go back 20 years most houses had proper eaves but now they are less common. As I travel around I sometimes see new houses with eaves on the front facade but non elsewhere which I think looks weird.

If you are thinking about Eaves on your new house here are some advantages and disadvantages.

Advantages

  • The eaves keep the rain off the walls. As well as improving the weather proofing this helps improve the thermal performance of the walls in winter.
  • They will shade north facing windows in summer while letting the winter sun in. (This effect is negligible for windows facing in other directions and only about 50% effective for full length windows and patio doors)
  • Appearance. I think they give a more finished appearance and the shadow line adds interest.

Disadvantages

  • Cost. A typical cost is around $60/m2 so 600mm eaves all the way round a typical house can add around $3,000 to the cost. 450mm eaves will be a little bit cheaper.
  • You can’t build as close to the boundary which can be important if you have a narrow block.

As for me my previous house had eaves but my last house doesn’t so I have a foot in both camps. I didn’t mind the look of the design without eaves and I’ve built a pergola on the north side for shading.

Are you for, or against, having eaves on your new house?
