Types of Home Extensions

There are many ways to expand your home, depending on your needs and property layout:


  • Single-storey extensions are ideal for adding extra living space, like a family room or larger kitchen
  • Second-storey additions create new bedrooms, bathrooms or even a private retreat without reducing outdoor space
  • Rear extensions can open up your home for indoor-outdoor flow, perfect for entertaining
  • Granny flats or self-contained studios are great for guest accommodation or rental income
  • Garage conversions offer a smart use of existing space, turning unused areas into offices, gyms or extra bedrooms


Each type can be customised to suit your home’s style and structure.

  • How much do home extensions usually cost?

    The cost of a home extension varies depending on the size, complexity, materials and location of the project. Single-storey extensions are generally more affordable than second-storey additions, but all costs should include planning, permits and finishes.
