I've taken the precaution of taking hundreds of photos of our house-in-construction to ensure I can track down all the important things that will (by the end of today) be within walls. Here's hoping I've done enough...
@lightweight Great idea. Should be part of a mandatory user manual that comes with the house... :)
heres an idea - rolls of paper with large legible metre markings that can be attached horizontally and vertically to the framing to give scale to those photos.
@bigblen I actually did (precariously) balance some measuring tapes for a few of them... I'm otherwise planning to give the builders the benefit of the doubt and assume they got the 600mm centres for studs, which offers some scale.
