What Eastern Melbourne Families Say About Building With Warrington Homes

Don't just take our word for it. Here's what families who've trusted us with extending or renovating their property have to say:

Vincent M testimonial

"The team were honest and transparent to deal with and finished the job on time and on budget"

We used Warrington Homes for a complete reno of our 1970s home including removal of some internal walls and relocation of internal stairs. The workmanship was second to none.

The team were honest and transparent to deal with and finished the job on time and on budget. Communication was great. As I have no trade background, we were totally relying on the fairness of Warrington Homes and they didn’t let us down.

Five years down the track and we’re still as happy with the reno as we were when the job was finished. Highly recommended.

"Even better than we could have imagined."

We engaged Warrington Homes to undertake our renovation.

Michael and the team were exceptional in all areas. Great communication with us every step of the way, sticking to time schedules (challenging during COVID times) and fabulous trades working for them.

They even got us back home when they said they would. We are extremely grateful to them for their attention to detail, ideas and advice. We love our home, it is even better than we could have imagined. Thanks Michael and the team.

Our Extension & Renovation

GUARANTEE

Zero Risk. Zero Excuses. Just Results.

We have some have a triple guarantee. Here's what you can expect:

Fixed Timeline Guarantee

We set a fixed timeline with you so you can plan and not have timeline blowouts.

Agreed target move‑in date from contract signing
If we run past the agreed date due to our delays, we will compensate
You get regular progress updates & clear explanations if approvals or site changes affect timing

For major extensions and renovations in Melbourne, typical timeframes can range from 9-10 months. We’ve streamlined our process to target realistic timelines for most projects without compromising quality.

No Hidden Variation Costs Ever

Fixed price locked in from day one. What we quote is what you pay

No hidden costs
No "variations" that inflate your budget
No budget blowouts

Most builders use variations to increase your final price as the job progresses, often adding thousands or even tens of thousands on top of the original quote. With Warrington, the scope is fully designed and costed before you sign, so there are no surprise variations blowing out your budget

12-Month Post Build Care

Full 12-month post-build care guarantee because quality doesn't stop at handover.

Covers all structural elements
Foundation to roof you we will fix
Touch ups 

Most builders disappear after handover. We're a family business built on reputation and because we have limited builds every year we build a strong personal relationship whilst building with you, meaning we want to make sure that everything is smooth for you and that you have the support behind you.

6 Reasons Why Families Trust Us With Their House Extensions In The Eastern Suburbs

Building your dream home is likely the biggest investment you'll ever make. Here's why discerning Melbourne homeowners trust us with that investment:

1

Every Trade Is Warrington-Approved (Not Whoever's Cheapest)

We've been doing this for a long time, we use the same electrician we've used for 15 years as with our head carpenter - Sean (Michael's son) has been working for Warrington Homes for over 15 years too.

2

We treat you like family, not project #247

We limit builds to 3-4 per year so you get our full attention. Some builders juggle 50+ projects. We focus on yours.

3

One team handles everything

Design, council approvals, construction, finishing. All under one roof. When something goes wrong, we fix it without the finger pointing

4

We Spec Materials For 30-Year Performance (Not 7-Year Warranty)

We spec for 30+ years because we're building homes that will outlast us ensuring your home is built for the long run.

5

Energy Efficiency

We aim to target 7 stars on every build because it lowers your energy bills (forever), more comfortable all year round, higher resale value, better for the environment overall.

What Nobody Tells You About Planning A Major Home Extension or Renovation In Melbourne

Hi aspiring home builder,

After delivering major extensions and renovations across Melbourne's Eastern Suburbs for 120 years, we've seen every costly mistake families make. Here's what most builders won't tell you but absolutely should.

1. Your $500K Budget Can Quietly Become $650K (Before You've Even Started)

- Large renovations and extensions are notoriously prone to scope creep. What starts as "extend the back and redo the kitchen" can balloon once structural issues, services upgrades and finishes are properly costed.

- Builders who give you an early ballpark without a full site investigation, engineering review and detailed inclusions list are setting you up for variation shock later.

- Red flags: vague provisional sums, "TBC" on structural items, no mention of services (plumbing, electrical, HVAC relocation).

Our approach: Full design, site investigation and inclusions schedule before you sign, so the price you commit to is genuinely fixed, with far fewer nasty surprises.

2. Council Approvals For Major Works Take Much Longer Than You Think

- For extensions and structural renovations above a certain scale, planning permits are almost always required. In Melbourne's Eastern Suburbs, that process typically takes 4 to 8 months.

- Heritage overlays (very common in Whitehorse, Boroondara and Manningham), neighbourhood character controls, BAL ratings and easement requirements can all trigger additional rounds of questions and delays.


Our approach: We coordinate town planners, engineers and reports so you're not stuck chasing council paperwork while trying to live your life.

3. Your Existing Home Can Hide $30,000 to $80,000 Worth of Surprises

- Once walls come down, the reality of what's inside an older Melbourne home often emerges: asbestos sheeting, substandard wiring, undersized footings, rotted framing or old cast-iron plumbing that needs full replacement.

- The older your home (pre-1980s especially), the higher the chance of discovering something that adds real cost and time.

Our approach: We do a thorough pre-construction investigation so likely risks are identified and costed before you're committed, not halfway through demolition.

4. Living Through a Renovation Is Harder Than It Sounds

- At the $500K to $750K+ level, works typically run 9 to 10 months sometimes more. Many families underestimate the physical, emotional and financial toll of living on-site or renting while the project runs.

Our approach: We give you realistic, fixed timelines upfront so you can plan your life around the build. And if we run late due to our delays, we compensate you.

5. Staging Your Renovation Sounds Smart. But It Often Costs More In The Long Run

- Many homeowners try to break a large renovation into stages to manage cashflow. In reality, returning to already-completed work to connect new works adds significant cost in labour, materials, re-plastering, re-painting and trade remobilisation.

- Electrical and plumbing runs that weren't planned from the start often need to be rerouted or upgraded at significant extra expense.

Our approach: We help you plan the full scope intelligently upfront, even if delivery is phased, so you're not paying twice for the same work.

6. "Fixed Price" Doesn't Always Mean What You Think It Means

- Many builders use the phrase "fixed price" loosely. The contract may be fixed in principle but riddled with provisional sums and exclusions that allow them to charge variations as the job progresses.

- On a $600K project, variations can easily add $50,000 to $100,000, often for items that a thorough pre-contract process would have identified from the start.

Our approach: Every inclusion is specified before you sign. No hidden provisional sums. No variation surprises. The price you commit to is the price you pay.

7. The Trades On Your Job Matter More Than You Know

- On a large extension or renovation, the quality gap between a good tradesperson and a poor one is enormous, especially for tiling, plastering, joinery and waterproofing, where defects often don't show up until months after handover.

- Volume and project builders routinely use whoever is cheapest and available. Rotating subcontractors don't know your project, your standards or each other's work.

Our approach: We work with a small group of long-term trade partners we've trusted for 10 to 15+ years.  Sean is my son and has been a licensed carpenter for 15+ years. The people on your site know our standards, and we know exactly what quality they deliver.

To your forever home,
