Our house is weatherboard house built in the 1950s and then in the 70s someone put brick cladding on it which in my opinion is nowhere near as appealing. This now exposed weatherboard is also going to be removed for newer board and our extension will be done in weatherboard to match.
Anyway the thing we can't get over is already this few days of demolition has caused arguments with our building company who were trying to claim they didn't know the weatherboard was there and wanted to charge us extra to remove it.
To cut a long story short I am happy to say we managed to prove that they did know, we had e-mails about it and so they will not be removing the contract variation they were trying to make us pay. So lesson learnt - keep everything in writing and stick to your guns!
