Guys, I am trying to add a garage along the boundary , basically at the end of the driveway. Anyway I have determined that along the boundary my neighbour has an asset / sewer pipe. So i call yvw . Anyway the person at yvw basically says the following: The pipe is 300mm diameter concrete. It's 4m deep and runs the length of the boundary And you cannot build a building within 1m of the boundary. Has anyone encounted this before and have built beyond their restriction, what was involved, who got involved an engineer for example, what was the cost.? What is considered a building, is it possible to make a lightweight garage,, anything pls help It just won't make any sense to build a garage 1m in .
