Straight out of school Jonny Watson learned to build under one of Southland’s top builders. In his time with him, he built Master builder award-winning homes. He is grateful for the experience he gained with quality being of the highest. 

After getting married and having a young family JW building was established. Our goal is to deliver a high quality build and in efficient time frames.
