Australia’s Top 10 Most Common Building Defects
Buying a home is a dream for many, but the excitement of ownership can quickly turn into a nightmare if the property has hidden defects. Even brand-new buildings can have serious flaws, as highlighted by concerning cases like Opal Tower and Lachlan’s Line. Michelle May, a prominent Sydney buyers agent, warns of widespread defects in newly constructed apartments across Australia. Despite these risks, the demand for housing remains high, fueled by tight rental markets. This puts first-time buyers in a particularly vulnerable position. As reported by Savings.com.au, they face high construction costs and the potential financial devastation of fixing defects.
Don’t let your dream home become a money pit. Awareness is your first line of defense. In this blog, we’ll expose Australia’s top 10 most common building defects, helping you make informed decisions and avoid costly surprises.
