39 - PROS & CONS Negatives of building tall: Tall buildings are more expensive Use more energy Take light and cast shadows Causes stronger winds Disconnect neighbours from each other Ruins the skyline of the city Positives of building tall: Tall buildings have higher sales value Cause less commuting Help create cool and shadowy streets Shelters for strong winds Provide private spaces with good views Make the skyline of the city Add identity and character to a city
