What reviewers think

Most reviewers praise IQ's build quality, transparent communication, and caring team approach. The company delivers custom homes on time and on budget, with staff like John, Dwayne, Daniel, and Dave named for their attentiveness. Two low-star reviews flag trust issues and unexplained costs, marking a caveat worth considering.

Based on limited recent reviews, so treat this as low-confidence.

Best for: Custom home builders wanting collaborative design input and responsive on-site supervision.
Think twice if: Two reviewers report trust concerns and cost surprises; if you value predictable scope and pricing, clarify variations policy upfront.

Strengths

  • long track record (operating since 2008)
  • named supervisors with high client recognition
  • design flexibility; customers make changes without penalty until build starts
  • after-care support; staff attend minor issues after handover

Worth knowing

  • Named supervisors John, Dwayne, Daniel, Dave praised for availability and attention to detail
  • After-care manager Arnold handles post-handover issues
  • Design phase allows unlimited changes before build commences; variations during build incur costs with agreed margin
  • One custom timber-frame home completed in under 6 months from earthworks
  • Granny flat builds noted for seamless integration with existing homes

Questions people ask

Can I make changes to my design before build starts?
Yes. Design changes are welcome at no extra cost before you commit to building. Once the build begins, changes incur variation costs, but the builder's margin is fixed and predictable.
How long does a custom build typically take?
One reviewer's timber-frame house went from earthworks to handover in under 6 months. Design timescales vary depending on the extent of changes you request.
What happens if something needs fixing after we move in?
IQ has an after-care manager (Arnold mentioned) who responds promptly to issues during the maintenance period and even after handover.
