Prior to building our home, the land developer rejected our plans and forced us to render any wall that was street facing. After our house was built, I enquired about a neighbour not having to render the same walls and was informed they made a mistake when processing our plans. I have requested that the developer (who has admitted being at fault) fix the mistake and remove the rendered walls and replace with face brick as per our original plans. Developer has been very condescending regarding this issue and initially offered me a $50 Bunnings voucher which was subsequently increased to a $250 Bunnings voucher for me to effectively go away. Developer recently provided me with hand written note saying they informed our builder we didn't need to render everything that was rendered. However, after receiving original copies of documentation trail between Developer and Builder, no such note exists and all correspondence from Developer was electronically stamped, nothing hand written in any correspondence. Original copies were received off builder after I emailed both developer and builder to provide me with original copies of all correspondence. Developer has not responded to the request (basically I think they got caught with their pants down after fabricating a note to try and blame my builder). As the developer is not willing to fix the mistake, where should I go from here? Is the developer breaking any laws by fabricating documentation to pass the blame onto my builder?
