Two quotes for the same style of home can sit thousands apart, and the gap rarely comes down to workmanship. It usually comes down to what each builder has quietly classed as standard and what they’ve pushed into the upgrade column.
For anyone comparing custom luxury home builders in Torquay or across the Surf Coast, the only way to compare quotes properly is line by line, area by area, against a genuine premium benchmark rather than a builder’s own definition of “standard.”
This checklist sets out what a premium build should carry as standard in six key areas, and where the line to a genuine upgrade actually sits.
Double glazing across all habitable rooms is the baseline for a premium build on the Surf Coast, where wind exposure and temperature swings are part of daily life. Low-E coatings on north- and west-facing glass should also be standard, since they materially affect how a home performs through summer without relying on mechanical cooling to do all the work.
Triple glazing, structural glass corners, and oversized sliding or lift-and-slide door systems are legitimate upgrades. They carry real engineering and hardware costs beyond standard double glazing, and it’s reasonable for these to sit outside a base allowance.
A premium build should carry insulation well above the minimum required by the National Construction Code, typically including higher-rated wall and ceiling batts, sarking, and a genuinely sealed building envelope. Thermal performance shouldn’t be treated as a line item you add later; it should be part of the base design.
Specialised systems such as structural insulated panels, double stud wall construction, or a fully custom passive design strategy are upgrades. They deliver a further step in performance beyond a well-insulated standard build, but they involve different construction methods entirely, not just a thicker batt.
Solid, soft-close cabinetry throughout kitchens, bathrooms, and laundries should be standard in a premium build, along with a genuine stone benchtop, not a laminate finish dressed up in marketing language. Custom-designed joinery layouts, rather than off-the-shelf configurations, should also sit inside a premium base specification.
Book-matched stone, waterfall edges, integrated European appliances, and fully custom joinery details such as hidden hardware or bespoke storage solutions are legitimate upgrades. These involve either rarer material selections or a meaningfully higher level of custom fabrication.
Engineered timber or large-format tiles should be the baseline across main living areas in a premium build, not a budget-grade laminate. Underfloor heating in bathrooms is increasingly a reasonable standard inclusion at this price point, given how affordable the technology has become relative to the rest of the build.
Solid hardwood flooring, natural stone, and extending underfloor heating through full living areas rather than just bathrooms are genuine upgrades. Each involves a real jump in material cost or installation complexity.
Premium tapware and fixtures should include quality brand ranges with a proper warranty, not the base-tier products within a brand’s own catalogue. Full-height tiling in bathrooms and a properly specified ventilation system should also be part of a genuine premium standard.
Designer or architect-collaboration tapware ranges, freestanding baths beyond a standard allowance, and custom vanity design are legitimate upgrades. These sit at a different price tier because of design exclusivity or bespoke manufacture, not because the base range was deliberately under-specified.
Locking tapware and fixture selections in early is part of what a realistic custom home build timeline actually looks like, since late changes here are one of the more common sources of delay.
A premium build should include a completed driveway, basic retaining where the site requires it, and a functional, tidy landscaping package as part of the base contract, not left as a client-funded afterthought once the build is finished.
Pools, outdoor kitchens, extensive hardscaping, and architect-designed landscape plans are genuine upgrades. They represent an entirely separate scope of work rather than a finish level within the existing landscaping allowance.
Ask each builder to itemise what is included as standard in each of these six areas, not just the total contract price. Where a quote looks lower, the gap is almost always sitting in one or more of these categories, most often glazing, insulation, or joinery, since these are the easiest places to trim a specification without it showing up until selections.
As a residential builder that sets these standards out before contract, we’d rather a client compare us properly against a competing quote than assume all “premium” builds mean the same thing.

The gap almost always comes down to what each builder has classed as standard versus upgrade. A lower headline price often means lower-grade glazing, insulation, or joinery as the base specification, not a genuine saving.
For a build on the Surf Coast, yes. Wind exposure and temperature swings make double glazing, together with Low-E coatings on north and west facing glass, a baseline for thermal comfort rather than an optional extra.
Engineered timber is a genuine premium standard inclusion and performs well in most living areas. Solid hardwood is a legitimate upgrade, involving a higher material cost and generally a different installation approach.
A functional, tidy landscaping package and a completed driveway should sit inside the base contract for a premium build. Pools, outdoor kitchens, and architect-designed landscape plans are a separate scope and a genuine upgrade.
It depends on whether you’re paying for materially different fabrication, such as book-matched stone or custom hardware, rather than paying more for the same specification under a different name. Ask for the exact material and hardware brand behind any joinery line item before agreeing to the upgrade cost.
Yes. Insulation above the National Construction Code minimum, combined with a sealed building envelope, has a direct and measurable effect on how much heating and cooling a home needs to stay comfortable through the year.
Yes, and it’s the most useful comparison you can make. Ask each builder for a written inclusions list across glazing, insulation, joinery, flooring, tapware, and external works, and compare those line items directly rather than comparing headline prices alone.
