If you are buying a home off the plan, it means that you agree to purchase a home that's yet to be built. Your decision will be based on the building plans and discussions with the developer or builder about the design and included features.
Being unable to physically see an apartment or house prior to buying can make it hard to get a sense of key elements such as light and ventilation. Considering key principles of energy efficient building design can save energy, water and money, while creating a more enjoyable and comfortable home. Knowing what questions to ask your builder is crucial to making an informed decision.
