First Floor or Second Storey Additions in Sydney

Adding a first floor addition in Sydney to your existing property can give you that extra space your growing or changing family needs. You’ll find most homes in Sydney can support a second storey addition, but it is always essential to check with your designers first. You can add any number of bedrooms, a bathroom, or another living area for the kids to have their friends over, or why not add an ensuite and walk-in-robe off your master bedroom. First floor additions in Sydney are a good solution if your property doesn’t have quite enough area for a ground floor extension or if you don’t want to lose any of your backyard. Here are some things to consider before planning a second storey addition along the North Shore and Northern Suburbs:

  1. At the beginning of the project, discuss your needs and limitations in detail with your designer and builder.
  1. Consider Council regulations and building code requirements before planning your first floor addition in Sydney. Setbacks from side boundaries, having enough area for landscaping, and not exceeding the maximum floor area of the home are major Council considerations when considering options for extending. If your property has large areas of paving, driveways, or a pool, a second storey extension is often a wise option to pursue.
  1. Ensure that your neighbors feel their privacy is maintained. Similarly, your extension needs to be designed to maintain your privacy from homes around you.
  1. Check to see if you need to modify your own home insurance during an extension.
  1. Hire a licensed builder to provide the necessary insurances before they can start construction.
