The Benefits of Second <br> Storey Extensions

The Benefits of Second
Storey Extensions

It may come as a surprise, but a double storey extension might be more cost effective than you think, especially in comparison to a ground floor extension. Most of the financial concerns that come with ground floor additions are effectively negated by building upward and adding a 2nd floor, concerns such as:

  • Avoiding poor access to the property for excavation and construction machinery
  • Impact on foundations by trees
  • Sloping of the land (can affect excavation)
  • The presence of established gardens, sheds, decks and patios
  • Reduction of recreational space for kids, pets, entertaining, etc.
Other benefits

Other benefits

Other benefits that come with opting for a second storey extension include:

  • Fewer disruptions to those living in the house, as the majority of work is done from the ‘outside’
  • Keeping your lovely gardens, entertaining areas and kids’ play spaces
  • Leaves sufficient backyard space for future enhancements like a swimming pool, gazebo, tennis court, vegetable / flower garden or just an outdoor entertaining area.
