Browse Forums Building A New House 1 Jul 23, 2009 10:20 pm Hi there I have some questions about eaves - Im pretty sure 300mm is the standard size and a few people upgrade to 450mm. Our designer has sketched our roof line with 600mm.... As Im making him change some stuff to do with the roof line anway (I fought tooth and nail to get my alfresco under the roof line ) I figured I might as well pose the eaves question... Im not good with technical stuff so would prefer lamens terms... What is the advantage of 600mm eaves to 450mm eaves? Is it significant enough to justify what I assume would be an extra cost?

Re: Eaves - 450mm vs 600mm 2Jul 23, 2009 10:31 pm Our eaves are 450mm and seem ample to me and look in proportion to the house. Have not seen any bigger ones around Re: Eaves - 450mm vs 600mm 4Jul 23, 2009 10:36 pm Cant say I would know what size the eaves were by looking at a house But I am a little concerend about how it would look Some more info on our house if it helps? West: Garage (no windows), Laundry, Bathroom and two bedroom windows North: One bedroom window East: Majority of our windows - one thin window in the HT, two narrow in family, two section of bifolds between 3m-4m, two large windows of about 3m, our ensuite window South: 4 narrow windows Custom European Cabinets - Melbourne Kitchen Specialist PM for business details as website currently being updated!

Re: Eaves - 450mm vs 600mm 5Jul 23, 2009 11:06 pm I have always thought that eaves of an appropriate width are to shade the windows from the sun in the middle of summer. In the middle of winter they should be narrow enough to allow winter sun and warmth in. The appropriate width depends on your distance from the equator and how far below your eaves the windows go down. I expect in Melbourne your eaves should be at the very least 600mm on the north side. See this Australian government website for excellent information about eaves, insulation, etc.: http://www.yourhome.gov.au/technical/fs44.html Re: Eaves - 450mm vs 600mm 6Jul 24, 2009 9:42 am Our eves are 600mm and they look good to me. This was the standard for our builder. I suppose the biggest benefit would to be able to keep the windows open when raining more then smaller eves (like in summer when it's hot). We haven't moved in yet to confirm this though. Re: Eaves - 450mm vs 600mm 7Jul 24, 2009 11:06 am One thing I like about 600 eaves is for a house with 2400 high walls that doesn't have brick infills above there windows, with a 20º-22.5º (pretty common) roof pitch the infill can be hidden because the eave line finishes flush with the top of the windows and doors. That's just a personal thing though as I don't like the look of supplements for brick infills. Re: Eaves - 450mm vs 600mm 8Jul 24, 2009 5:05 pm Slugger, dont suppose you have any pics you would mind posting? nomad, we will be having brick infills I think our roof pitch is different though.... Does roof poitch affect it much? And our ceilings are 2.7m cyberman, did I mention Im not a scientif whizz I read the page but I dont know how to work out whats beneficial for me. I dont even know how to work out the distance from the equator.. This "Reduce eaves width to 42-43 percent of H to extend the heating season past the equinox" made me go like this Some interesting points on the website cyberman posted.... Quote: Keep the area of glazing on east and west elevations to a minimum where possible, or use appropriate shading devices. Adjustable shading is the optimum solution for these elevations. So its best not to glaze east and west windows (where our majority is)? Custom European Cabinets - Melbourne Kitchen Specialist PM for business details as website currently being updated!

I don't think mine will look out of place. Only at frame stage at the moment. The house two doors down also has 600mm eaves and it looks fine to me. http://i519.photobucket.com/albums/u353/joles_photo/2009-07-23_17-30-51_23072009997.jpg I leave you to fend for yourself, figure things out yourself. Terrence Malick Re: Eaves - 450mm vs 600mm 11Jul 24, 2009 6:25 pm In our estate, it is a mandatory requirement to have 600mm eaves. Here are some recent photos where you can see the eaves and the roofline. FWIW, we have 2700mm ceilings and brick infills as well. http://i20.photobucket.com/albums/b227/megsyg/LOT%20232%20Station%20Creek%20Way/IMG_0307.jpg I love the look of eaves HTH, Building a Modified Lawson Modern 29 @ Botanic Ridge, Cranbourne South, Victoria Re: Eaves - 450mm vs 600mm 13Jul 24, 2009 6:31 pm Thanks meghan, it doesnt look odd at all! Did you get the 600mm plus double glazing to the East and West? Mind if I ask WHY you choose 600mm? You too Jo?

Re: Eaves - 450mm vs 600mm 14Jul 24, 2009 6:34 pm The facade we chose (Daintree) came with 600mm eaves to the front and around the corner (for around a metre) of the garage and master bed. We just extended them. I leave you to fend for yourself, figure things out yourself. Terrence Malick Re: Eaves - 450mm vs 600mm 16Jul 24, 2009 7:30 pm Here's another shot front on. It's a mandatory requirement for all houses to be built with 600mm eaves @ Botanic Ridge Estate. Didn't bother with double glazing as we more than aced 5 star with the plans as they were.

I dont even know how to work out the distance from the equator. This "Reduce eaves width to 42-43 percent of H to extend the heating season past the equinox" made me go like this Allow me to translate: In any place from Melbourne to Brisbane, they are saying the eaves should be 42 to 45% of the Height (as is shown in the diagram on that webpage) from the eaves to bottom of the windows. Therefore is the distance from the eave to the bottom of the window is only 1000mm, then the eave should be about 450mm. Likewise if the distance from the eave to the bottom of the window is 2000mm, then the eave should be 850mm. EXAMPLES: My present house has 2700mm ceilings, but the eaves are 2400mm from the floor, the windows go down to 300mm from the floor, so the total "H" distance is 2100mm. Therefore my northern eaves should be 900mm (including the gutters). Another example, if you had standard 2400mm ceilings, assume the eave height is then 2100mm from the floor. If you had 1400mm high windows (which would start at 700mm from the floor), then you could get away with 600mm wide eaves.

The front of the house will have 2700mm ceilings and windows 200mm from the floor (as the house will be on stumps, I wanted it as small as possible) so that makes it 2500mm so my eaves should be 1125mm including gutters.... So I think its best to stay with 600mm Meghan, thanks for the pics! They are useful in two ways - to show the eaves and the portico! I was trying to explain to the designer that exact same portico Custom European Cabinets - Melbourne Kitchen Specialist PM for business details as website currently being updated!

Re: Eaves - 450mm vs 600mm 20Jul 25, 2009 6:27 pm I_BUILD Is it just the way it looks in that pic or is the eave on the right hand side and the front of the garage 450mm? If that were the case the eaves wouldn't line up. cybermans examples all though relevant isnt quite accurate because you can alter the roof pitch to achieve those eave heights using a much smaller eave. Versaloc is a mortarless besser block system that still needs a properly engineered footing. If you just do a 400x200 footing it will fail in time. At 17m long you need it… 1 15087 My daughter and son in law are about to start building, they are having a 600mm induction cook top and 900mm oven. It's personal preferance 5 10780 Update from me! Couldn't find the trimmer - not sure if there isn't one simply because the eave is so narrow. Went ahead with the spring toggles and it all worked out… 7 5816 |
