It’s the number one question every homeowner asks when they start planning an extension or a full-home reno: “How long will it take?” 

It’s a fair question. Renovations can be disruptive. You’re juggling school drop-offs, figuring out where to sleep, and dealing with noise, all while needing a clear end date. 

At Baron Constructions, we pride ourselves on transparent scheduling and clear communication. We’ll show you the three main phases of any project and reveal the hidden factors that can speed up (or slow down) your timeline.

We give you a realistic breakdown of the typical timelines for different projects in the Melbourne construction scene.

The Three Phases of a Melbourne Renovation Timeline

A project timeline is usually broken into three distinct stages. The construction phase is often the shortest; it’s the planning and approvals that surprise people!

Phase Description Typical Duration (Major Renovation/Extension)
Phase 1: Planning & Pre-Construction Design, drafting, engineering, council approvals (building & planning permits), and builder quote finalisation. 3 – 9 Months
Phase 2: Construction (On-Site) Demolition, slab/framing, lock-up, fixing, final fit-out, handover. 4 – 8 Months
Phase 3: Post-Construction Defects liability period, final clean-up, and official completion documentation. 1 – 2 Months (concurrent with living)

The Construction Phase Breakdown (On-Site)

While every project is different, here’s a rough guide to how long various common Melbourne projects usually take on-site:

  • Small Renovation (Kitchen/Bathroom): 4 to 8 weeks per room (if structural changes are minimal).
  • Medium Renovation (Ground Floor Extension, 1-2 Rooms): 4 to 6 months.
  • Large Renovation (Full Home Renovation or Second-Storey Addition): 7 to 12 months.

Builder’s Reality Check: These times assume a fully approved plan, no supply issues, and good weather. We always build in contingency time (a buffer) to handle the unexpected.

The Factors That Speed Up (or Seriously Delay) Your Project

Understanding these factors is key to managing your expectations and minimising frustration.

1. Council Approval (The Biggest Factor)

This is often the main hold-up.

  • Simple Project (Building Permit Only): 4-6 weeks for approval.
  • Complex Project (Planning Permit Required): 3-6 months. This is often triggered in older suburbs or in areas with strict neighbourhood character rules (such as parts of Whittlesea or Hume City Council).
    • How we manage it: By submitting complete, error-free documentation the first time and starting the approval process as soon as the design is fixed.

2. Client Decision Fatigue & Scope Changes

This is the biggest internal factor for delay.

  • The Problem: Waiting two weeks for you to choose the exact tile, tapware, or floorboard finish, or suddenly deciding you want to move a wall after framing has started.
  • How we manage it: We provide a clear schedule of finishes and deadlines right at the start. Our clients are given fixed deadlines for making selections (taps, tiles, paint) to ensure materials arrive on time.

3. Supply Chain Issues

While things are improving, global supply issues, especially for custom items, are still a factor in Melbourne.

  • Long Lead Items: Imported windows (especially custom sizes), designer tiles, and specific structural steel can have lead times of 8 to 16 weeks.
  • How we manage it: We order these items as early as Phase 1 (Planning) and ensure they are ready for on-site installation the moment they are needed, preventing work stoppages.

4. Weather (The Melbourne Factor)

We can’t stop the rain, but we can plan around it. Heavy Melbourne rain can delay foundation work, concreting, and roofing.

  • How we manage it: We prioritise ‘lock-up’ (getting the roof, windows, and external doors in) as quickly as possible to protect the internal structure and allow work to continue regardless of the rain.

Can I Live in My Home During a Renovation?

This is a critical question for your family’s sanity and the timeline.

  • For Extensions: Usually, yes, but it will be messy and inconvenient. We aim to keep the main service areas (kitchen/bathroom) functional until the last possible moment and seal off the construction zone completely.
  • For Full-Home/Second-Storey Renovations: We strongly recommend moving out. Living without a functioning kitchen, or dealing with major dust and noise from a second-storey build, adds stress and can actually slow down our teams. It’s usually worth the rent for a cleaner, faster, and safer build.

Renovating is a massive commitment of time and resources. Choosing a builder who provides a realistic, detailed, and transparent schedule is just as important as choosing one who can deliver quality work.

At Baron Constructions, we build trust with a clear plan. We minimise surprises and keep your project moving so you can get back to living in your beautiful, finished home sooner.

FAQs on Renovation Timelines

When does the builder’s warranty period start?

The typical 10-year structural warranty and 12-month non-structural (minor defect) warranty start on the date of handover (or issuance of the final occupancy permit), not the day we start demolition.

How does Baron Constructions communicate schedule changes?

We run a weekly check-in with our clients, providing an updated schedule forecast, detailing what work is happening that week, and explaining any necessary adjustments to the plan. Transparency and clear, upfront communication are essential for a good client relationship.

What part of the build is the fastest/slowest?

The fastest part is typically the framing stage (once the slab is cured), as it goes up quickly. The slowest part is often the fixing stage (cabinetry, tiling, painting, detailed trim work) because it involves multiple trades working sequentially and requires meticulous attention to detail.
