Browse Forums Building Standards; Getting It Right! 1 Sep 03, 2009 3:07 pm Hello, first of many post I am thinking. I am unsure of what are the ceiling height requirements. The BCA spec is for 2400 habitable/2100 other. Is it allowable to have beams intrude into this? I read in another section that the beam/rafter height allowable in for a veranda is 2100(Vic), but am not sure if this is applicable to internal habitable spaces. I am building a two story dwelling with the upper floor supported by F17 2/290x45 (5 meter span) 1800FLW with MGP10 90x45 Joists @450 centers. Can I attach the ceiling cladding (foilboard at this stage) to the underside of the joists and measure the ceiling height from there, allowing the upper bearers to protrude into the space below. This would maintain a beam height of over 2100. Edit : or do I need to measure to the bottom of the bearers? cheers, Jack Trezise French Island (soon) Mornington atm Re: Ceiling Height (measured to where) 2Nov 30, 2009 4:28 pm According to the BCA where a habitable room that is not an attic requires a height of not less than 2.4m over two-thirds of the floor area of the room. So you have to measure the area between the beams (assuming you have 2.4m height minimum) and calculate whether it covers two-thirds of the floor area. Andy ok thanks - yes was wondering if that should have been listed as Option Three! 2 7754 I'll look into different shower heads and ask the plumber about some engineering and see what he says. Thanks 2 9568 i imagine you also have another contract with an architect? and yeah, whatever other's said about special conditions and appendices 16 16026 |
