We've just signed the contract for our new custom built house and changed from Canterbury windows to another supplier.
Ordinarily, the builder works with Canterbury window standard sizes - http://www.canterburywindows.com.au/sit ... 20aw-3.pdf
Our new supplier can custom make to any size & herein ****** the problem.
The builder's brickies have advised to spec them to 300mm increments and they'll work to those sizes.
I'm not sure about this, as I understood it window sizes are typically based on brickwork dimensions - http://www.constructoz.com.au/Tables/BrickDims.htm
Heights would range from 600, 940, 1030, 1200, 1370, 1540, 1800, 1970, 2140 & 2400.
Widths would range from 610, 730, 850, 970, 1090, 1200, 1330, 1450, 1570, 1690, 1810, 1930, 2050, 2170, 2410, 2530, 2650, 2770, 2890, 3010, 3370, 3610.
Our window schedule provided by the builder (in-house draftsperson) looks like this;

Should I specify exact 'stud opening' sizes (ie. 610w x 2170h) with my supplier or should I just provide the above window sizes to my supplier and allow my builder to work to whatever finished sizes they receive?
I've been told they can 'gauge' the brickwork to suit the opening, but isn't it just easier to work with standard window sizes?
