The just building group difference
One Builder. Every Stage. Zero Stress.
Most building projects involve juggling multiple contractors, chasing permits and managing timelines yourself. At Just Building Group we handle everything – one point of contact from first conversation to final handover.
Full Project Management
From your first consultation through to final handover, we manage every single step – design, council approvals, planning permits, trades and timelines. You have one point of contact throughout and you will never need to chase anyone.
Licensed & Registered Builder
Justin Monk is a fully licensed and registered builder in Victoria with over 30 years of experience. Every project is completed to the highest standard, fully insured and backed by the credentials and reputation that only come from decades of quality work.
Local Peninsula Knowledge
We’re not a city builder that drives down for jobs – the Mornington Peninsula is home. We understand local council requirements, coastal conditions, Peninsula blocks and the lifestyle our clients are building toward. That local knowledge makes a genuine difference on every project.
Transparent Pricing
No hidden costs, no nasty surprises and no vague estimates. Before any work begins you will know exactly what your project costs and what’s included. We believe honest, transparent pricing is the foundation of every great client relationship and successful project build.
