Went down to the block again today just to see how much had been done. As you can see by the photo below the plumbing is done.
Don't know if the slab will get poured as planned this Tuesday as they are forecasting rain. Keep your fingers crossed that they are wrong.
Also went to the HIA Building and Renovation show today and bought myself a letterbox. Given that the developer has restrictions on the type of letterbox you can have I have found it difficult to find something I liked. I found one (pic below) made my 'Milkcan Letterbox Company (available from Bunnings). I will stain it to match my garage door. The letterbox I have in the house I am living in at the moment has been stolen twice. I don't think anyone will be able to run off with this one.
