Rotunda Cost Calculator
Estimate the cost of a rotunda (gazebo). The size and the materials or finish are the main cost drivers, along with site preparation and access.
Your rotunda details
Your estimate sits within the typical range.
A built rotunda needs a slab or paved base, which is a separate and significant cost, and a tiled or Colorbond roof costs more than a kit's light roof but lasts.
A rotunda usually needs a concrete or paved base, which is a separate cost, and a permanent one often needs council approval. A kit gazebo is far cheaper if you just want shade and can live with a lighter structure.
💰 Ways to save
- A DIY kit costs far less than a custom build if you are handy, but factor in your own time and tools.
- Level and clear the site yourself where you safely can, you are paying trade rates for any prep otherwise.
- Get a few quotes and ask what the base or slab adds, it is often a separate and underestimated cost.
