hi coleraine64 , difficult question, if your after a medium size house nothing to flash on an average block then buy a house. i think its down to where you want to live country, beach or suburbia. yes builders are competitive and house prices are probably better! I bought a small house on acreage and i am in the process of building 2 extensions i think its down personal taste. I would use a draughts men for any plans , cheaper but no call backs for any questions the builder will need to work it out!
