Boundary pegs (also known as title or survey pegs) are used to mark out the boundaries of your lot before construction can begin on a development site. A Land or Building Surveyor will accurately measure out your site and establish boundaries which they will then mark out with pegs or stakes. It’s important to ensure your block is maintained before the construction stage as if pegs are missing or have been moved, sometimes you may have to bear the cost of having the land re-surveyed.
