An Owner Builder is an individual who takes responsibility for managing and carrying out construction or renovation work on their own property.
Instead of hiring a licensed builder to oversee the entire project, the owner builder coordinates trades, manages timelines, controls costs, and ensures compliance with building regulations.
This pathway is commonly chosen for home construction, extensions, renovations, or major structural work, allowing greater control over the project.
However, owner builders must meet specific legal requirements, approvals, and responsibilities before starting any work.
Owner builders may undertake different types of construction or renovation projects.
Common types include:
This involves building a house from the ground up.
