Browse Forums Building A New House 1 Apr 11, 2009 10:26 am Hi All, Do you agree that dimensions shown on a floor plan that we see on builder's websites are internal measurements and DO NOT include thickness of plaster board and/or brick work etc? That's what I think anyway. Otherwise it'd be too confusing for the general public to work out how large the room is. It's only when we see the working drawings that plaster thickness and brickwork dimensions are shown. I believe this is the case as the working drawings are designed for the builder to know the exact specifications. To the general public, all we care about is the internal measurement! The reason why I'm raising this questions is because our working drawing is short of over 1 meter because the builder has converted the internal dimensions shown on our floor plan into plaster walls & brickwork. Hence all our rooms are smaller! Not fair right?! Let me know what you think. Thank you Karma - what goes around comes around sooner or later...... Re: Dimensions on a floor plan 2Apr 11, 2009 10:30 am My understanding is that all dimension on all drawings are timber dimensions. Working drawings are also timber dimensions as far as I know. I leave you to fend for yourself, figure things out yourself. Terrence Malick Re: Dimensions on a floor plan 3Apr 11, 2009 10:47 am I just conducted a not very scientific experiment with a tape measure and measured my spare room width - interior wall to interior wall and it measures exactly 2.8m, the exact width the floor plan says. So, I would say the floor plan dimensions on your 'ordinary' floor plan are the interior measurements. Of course, you do lose a little space for furniture placement when you factor in the space taken by the skirting boards. Re: Dimensions on a floor plan 4Apr 11, 2009 12:25 pm PnSdreams, Can you post your floorplan (or a small section of it) or provide a link to it. It would be interesting to see how it's laid out. On mine the internal wall dimension, then the wall dimension, then the internal dimension, etc are shown. I should add that the "internal dimension" is before internal wall cladding (gyprock or render).

I have just resolved the issue with our builder and the problem with our "original" floor plan is that it is incorrectly shown. Hence, all dimensions shown on floor plans are from wall to wall (internal). It is the working drawings that include all exterior dimensions. It took us a while to work out what was wrong with our working drawing because the total length didn't add up to the floor plan even though the total square meters has not changed and I've also moved some of the internal walls around. Anyways, it's all good now. Fingers crossed there will be no more problems with the plan..... Karma - what goes around comes around sooner or later...... Re: Dimensions on a floor plan 6Apr 11, 2009 4:45 pm PnSdreams, Have a look at your drawings and see how thick your internal walls are (should be 90mm for timber-frame). I am of the same understanding as Joles ... the actual dimension of the room will be reduced by 20mm due to plasterboard (2-off). That is, if drawing says room is 3000x4000, actual internal dimension is only 2980x3980mm. Chris Re: Dimensions on a floor plan 7Apr 11, 2009 6:37 pm Hi Chris, Oh so the 90mm is the timber thickness. So if the room is 3000x4000 should it be reduced by 2 lots of 20mm due to plasterboard on both sides? ie 2960x3960 This is getting too technical for me Karma - what goes around comes around sooner or later...... Re: Dimensions on a floor plan 9Apr 07, 2010 8:26 pm I searched every forum and you guys seem to know what your talking about. The timber works and form work is ready for the slab pour and I wanted to measure the width of the porch. On the working drawings its says 1500mm but when I measured from timber to timber the width of the porch was only 1470mm. Should I wait till the frame goes up and measure the dimensions again or should be saying anything now ?or am I missing something? Re: Dimensions on a floor plan 10Apr 08, 2010 9:12 am According to http://www.buildingcommission.com.au/re ... IDE_07.pdf the length needs to be within L/100 or 5mm whichever is greatest when setting out. If you have looked through all of the above comments to ensure that you have allowed for timber thickness plaster thickness etc. you are right to argue in your case the dimension is only allowed to be 15mm off not 30mm.

Iam sure when they do the layout ,the surveyors ,carpenters not sure which ones ,are diligent and follow the working drawings .Then again its like any other product ,whats a couple of ounces here or there when you buying such a big item. There is room for error after all they are human Do we check every room size ,eaves ,pitch of the roof etc we should . I will try my best . Re: Dimensions on a floor plan 12Apr 08, 2010 8:21 pm Its pretty simple. Drawings are from bottom plate to the other side bottom plate. eg They make the frame out on the slab where the timber goes. Standards & tollerances says measurements are plate to plate. so, 4000mm will be less 10mm plaster and the scerting on both sides. However take a tape into a display home and it wall to wall.
