"As a rule of thumb, eaves width should be 45% of the height from the window sill to the bottom of the eaves. Aim for consistent sill heights where possible and consider extending the eaves overhang over full height doors or windows. This allows the 45% rule to be simply met with the following standard eaves overhangs:
- 450mm where height is 900–1200mm
- 600mm for a height of 1200–1350mm
- 900mm for a height of 1350–2100mm
- 1200mm for a height of 2100–2700mm."
We're considering building with Metricon but have been advised that the most they'll do is 600mm eaves.
We'll have 2700mm high ceilings, and large windows and full height sliding doors on the northern elevation (to the rear). We don't think 600mm would be enough to make the most of the winter sun and block out the summer sun. But we don't need super wide eaves right around the house, as 450-600 is fine for the other elevations. Sounds like Metricon aren't keen on customising the home design to cater for these eave requirements.
Anyone been able to achieve this?
