Builders and developers quoting a small commercial building in South Australia, an office, a retail shopfront, a medical clinic fitout, face the same question residential buyers face: do we need an architect, or just the right set of consultants coordinated properly. In SA’s smaller consultant market, that coordination problem is often sharper, not smaller.
What a small commercial project actually needs
Most small commercial builds do not need a standalone registered architect. They need drafting to a commercial standard, structural engineering, an energy report, a building surveyor who understands the relevant NCC class, and a development approval under South Australia’s Planning, Development and Infrastructure Act depending on use and zoning. Each of those is normally quoted, scheduled and managed separately, by separate firms, with no single party responsible for how they fit together.
The real cost is coordination, not drawings
A structural revision that arrives late holds up drafting. A missed compliance note holds up the building surveyor. A planning condition discovered mid project sends the drawings back. In a market with fewer specialist commercial consultants to draw on than Sydney or Melbourne, each of those delays tends to take longer to clear, not shorter.
Where EcoPrestige fits
EcoPrestige’s commercial supply rate is $2,300 per square metre plus GST for accommodation type uses and $2,200 per square metre plus GST for early learning typologies, conditional on a 2,400mm ceiling and being within 40km of the Melbourne Port for freight, figures outside those conditions are requoted for your site, never scaled. Alongside that supply rate, EcoPrestige coordinates the consultant set, drafting, structural, energy, building surveyor and development approval where needed, under one team.
One roof, one accountable team
That combination, drafting, engineering, compliance and supply coordinated by one team, is genuinely rare in commercial delivery anywhere, and more valuable again in a market with a thinner bench of commercial consultants. You keep your head contractor relationship exactly as it is. What changes is who owns the sequence between consultants.
What the full package actually costs
Under $800,000 in module supply value, the same consultant allowance applies: drafting $5,500, or $11,000 between $400,000 and $800,000, structural engineering $3,500, an energy report $800, a building surveyor $3,800, landscape design if required $1,200, and town planning if required $1,400. Fully loaded that runs $16,200 to $21,700 depending on your supply value and which optional items your site needs. At $800,000 and over, ECI applies instead: Stage 1 is a flat $4,000 plus GST feasibility fee, credited directly against your module supply cost if you proceed to order. Stage 2 is fixed by supply value and is never credited, $10,000 plus GST under $1 million, $20,000 plus GST from $1 million to $3 million, $30,000 plus GST from $3 million to $4 million, $40,000 plus GST over $4 million. Tell us your rough supply value and we confirm which path and which exact number applies before you commit to anything.
Why your consultant’s job gets easier
A consultant engaged through our ECI structure is not starting from a blank page. By the time they see your project, EcoPrestige has already done the structural computations and footing designs for the modular components, the fire engineering calculations, and the flood mapping where it applies. Drafting already covers services and penetrations, construction set outs, scope of works for plumbers and electricians, crane plans, transportation sequencing, the council submission pack, building surveyor review checks, and Section J calculations. Your consultant’s job becomes a secondary review, settling and certifying work that is already built, not pricing a fresh scope from scratch. If you already have a consultant, they can review and sign off directly. If you do not, we can put forward up to five for you to choose from. One line worth flagging: the in situ concrete slab sits with your own civil and building side, that is not part of what EcoPrestige delivers.
