Browse Forums Building A New House 1 Jul 10, 2018 10:12 am Hi, I'm hoping some forum friends can look at this and see if my thinking makes sense. My builders drafting team have changed a number of things on the position of my home on the block. They have basically centred it, even though I have requested it to be 920mm closer to the left boundary. They also changed the roof pitch but i cant see why it doesn't comply. See below. 1. Building Height Code is 8.5m above natural ground height. The height of a dwelling house is measured from the existing ground level, which is the ground level of a site at any point, before any earthworks (excavation or fill) have taken place. See link for Image. Facts: Building Height above natural Ground Level: Total Height 8240mm -360mm Cut 310mm M Class Slab 2740mm Ground Floor 310mm Subspace 2590mm First Floor 2650mm Roof 25° pitch Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Would there be any reason why the roof apex would not comply? 2. Balcony Size. Edmondson Park South Development Control Plan 2012 Page 48 Maximum Floor Area Controls section 3. The maximum floor area for balconies, decks, patios, pergolas, terraces and verandahs attached to a dwelling house with a floor level more than 3m above the existing ground level must not be more than 12m². Notes: The Exempt and Complying Code identifies inclusions and exclusions for calculating different floor areas. Facts: Balcony Height above natural Ground Level 2840mm -360mm Cut 310mm M Class Slab 2740mm Ground Floor -150mm Balcony Stepdown. Based on the above calculations and the definition of in the Control. The 12m² limit would not apply as the balcony height is below the 3000mm threshhold where a ruling and size limit would then apply. Appreciate your thoughts and thanks in advance. Re: Height compliance questions. Did you encounter this? 6Jul 15, 2018 3:20 pm One error I can see in your calculations: you're taking 360mm off the height for the cut. That's not consistent with what's on the plan provided, which only has that depth of cut at the extreme bottom right, and has fill in other areas. Your benching is at 70.34, which means even with the dimensions listed in your calculation, your roof apex is going to be just above 8.5 metres at the left above the natural contours provided. Due to the fall of the land, moving the house to the left looks like it'll increase how high that point is above the natural ground level. Re: Height compliance questions.
