7 Things to Know Before Choosing a Melbourne Builder

Before you sign with any Melbourne builder, the questions that protect you are whether the price is genuinely fixed, what is actually included, and who is accountable for quality. Getting clear answers up front is what keeps the excitement of a new home from turning into a costly headache later. Ask these questions:

1. Is the price genuinely fixed?
2. What’s actually included?
3. How much can I customise?
4. How is build quality checked?
5. Is the builder licensed and accredited?
6. How energy-efficient will the home be?
7. Can I see the home before I buy?

This checklist is written for first-home buyers across Melbourne’s growth corridors, including couples and families starting out, who are weighing a fixed-price turnkey townhouse. It is worth remembering that not all builder decisions are the same. The questions you ask may differ for a bespoke build or renovation, so this guide focuses specifically on what to consider when choosing a builder for a fixed-price turnkey townhouse.

1. Is the price genuinely fixed?

A genuinely fixed price should cover the home, agreed inclusions and known site requirements within the contract. It is different from a low advertised base price that can increase once essential items such as site costs, driveways, fencing and landscaping are added.

This is especially important when comparing custom and volume builders. A custom build may involve more variables, with final costs influenced by the design, engineering, materials, site conditions and choices made throughout the process. A pre-designed turnkey townhouse has fewer moving parts because the design, external appearance and inclusions are established before the contract is signed.

At Sienna Homes, the contract price is locked-in. The facade and external colour palette are also fixed, helping remove design changes that could further affect the price or construction schedule.

Everything required to complete the home is included in the agreed build price (right down to the letterbox), and buyers receive a clear stage-payment schedule after entering into a Master Builders contract. The land is purchased under a separate contract with the developer, so it is worth confirming both the build price and the land price when comparing your total cost.

2. What’s actually included?

The best way to compare builders is to examine the full schedule of inclusions, not the headline price. A genuine turnkey home should be ready to live in at handover, without the buyer needing to arrange essential finishing work or additional trades.

The word “turnkey” is not a regulated industry term, so inclusions can vary considerably between builders. For example, items such as flooring, driveways, landscaping, fencing, cooling, a dishwasher, letterbox or clothesline may be standard with one builder and an additional cost with another.

A volume townhouse builder can include more of these items within a fixed price because materials and specifications are selected across multiple homes. This creates cost efficiencies while giving buyers a clearer picture of the finished home from the beginning.

Sienna Homes’ turnkey townhomes include timber-look laminate flooring through the main living areas, carpet in the remaining areas, mineral stone kitchen benchtops and Fisher & Paykel appliances, including an oven, induction cooktop and dishwasher. Inclusions aren’t limited to inside the townhouse with landscaping, fencing, a driveway, letterbox, fold-down clothesline and motorised garage door all part of your final price. As always, buyers should always refer to their building contract for the exact inclusions of their chosen home.

3. Can I customise, or am I stuck with a standard design?

Volume and turnkey builders generally offer defined choices rather than unrestricted customisation. This is an intentional trade-off as limiting structural and external changes helps keep the price fixed, reduces design delays and makes the construction process more efficient.

A custom builder may allow you to alter almost every part of a home, but each decision can affect the price, engineering and build timeline. With a pre-designed townhouse, those details have already been resolved, reducing the number of costly or complicated decisions a buyer needs to make.

That does not mean every home needs to feel the same.

Sienna Homes buyers can choose from four designer-curated internal colour schemes: Classic, Scandi, Urban and Chalet. Each scheme brings together coordinated cabinetry, benchtops, flooring, tiles and paint colours, giving buyers a distinct look without needing to select every individual finish themselves.

A defined list of upgrades is also available across areas such as the kitchen, bathroom, electrical, cooling and security. Structural and external changes are not available because the designs have already been engineered and approved. For buyers who value certainty, this is part of what protects the fixed price and keeps the build moving.

4. How is build quality checked?

Every compliant new home in Victoria must be built under an approved Building Permit and stamped plans, meet the relevant building standards and pass mandatory inspections by a Registered Building Surveyor. A Certificate of Occupancy is required before the home can be occupied.

These requirements apply whether a home is built by a custom or volume builder, so important questions to ask include:

• How are inspections managed?
• When do they occur and what warranties and insurance apply once the build is complete?

Sienna Homes’ townhomes are independently inspected by a Registered Building Surveyor at four key stages: pre-slab, slab, frame and final. This means important structural and compliance checks take place throughout construction, not just at the end of the build.

Buyers may also appoint their own private building inspector if they would like an additional independent assessment.

Each home is supported by a seven-year structural warranty, domestic building insurance and Home Owners Warranty Insurance. Together with the mandatory inspection process, these protections give buyers a clear framework for accountability throughout their home’s construction process and just as importantly, peace of mind.

5. Is the builder licensed and accredited?

Before choosing a Victorian builder, confirm that its registration is current and appropriate for the work it performs. You should also look for established industry memberships, relevant awards and a track record of completed homes.

A licence confirms that the builder is registered, but experience and external recognition can provide an added layer of expertise. Industry-body membership can also indicate that the builder remains connected to professional standards and developments across the sector.

Sienna Homes (Sienna Building Pty Ltd) holds Victorian Builders Licence CDB-U 49207 and is a member of both the Housing Industry Association and Master Builders Victoria.

Sienna Homes has also received more than 14 industry awards, including the HIA Affordable Housing Award for three consecutive years in 2020, 2021 and 2022, as well as a Master Builders Victoria Best Display Home award.

Having operated since 2007, Sienna Homes combines the cost efficiencies and established systems of a volume builder with the more personal experience buyers often associate with a smaller business and is why you get “big builder choices, small builder service”.

6. How energy-efficient is the home, and what will it cost to run?

New homes in Victoria must achieve a minimum 7-star NatHERS rating under current energy-efficiency standards. The rating assesses how much heating and cooling a home is likely to need to remain comfortable, based on factors including its design, orientation, insulation and glazing.

A higher-performing home can stay warmer in winter and cooler in summer with less reliance on mechanical or external heating and cooling. Actual running costs will still depend on energy prices, appliances and how the household uses the home, but the building itself provides a more efficient starting point.

With a pre-designed townhouse, these requirements can be resolved as part of the design rather than treated as a late or expensive addition.

Sienna Homes townhomes achieve a 7-star NatHERS rating as standard and include double-glazed windows, insulation to the external walls and roof cavity, and water-saving fixtures and tapware. These features support everyday comfort while helping buyers manage long-term energy and water use.

7. Can I see the home before I buy?

Pre-designed home collections often allow buyers to inspect a completed example before committing and is a genuine advantage over a one-off custom home, which may exist only as drawings/plans/material samples when the contract is signed.

Walking through a display home helps you understand the scale of each room, the flow between spaces, the amount of natural light and how the finishes work together. It also gives you a more realistic look and feel of what you are buying, which is more than a floor plan can do.

Because Sienna Homes builds from a pre-designed townhouse collection, buyers can experience display homes in Clyde North and Rockbank before they commit.

Choosing a builder is ultimately about knowing what you will receive, what it will cost and who will be responsible for delivering it, so asking these seven questions will help you compare builders on the details that matter, rather than relying on the lowest advertised price.

For buyers who want to know exactly what the cost of their new home will be alongside a simpler building process, then a fixed-price turnkey townhouse hits the ideal sweet spot: the certainty and efficiencies of a volume build, enough choice to make the home feel like yours and support from start to finish.
