Built for Business — From Fit-Out to Full Build
Buildana delivers commercial construction with the same quality, transparency, and project management discipline we bring to residential builds. From office fit-outs and retail construction to warehouse, industrial, and specialty facilities — we manage DA approvals, BCA compliance, construction, and handover with clear reporting and fixed-price contracts.
Commercial buildings fall under BCA Classes 5–9, each with specific requirements for fire safety, accessibility, energy efficiency (Section J), structural adequacy, and services. We understand these classifications and build to them — Class 5 office, Class 6 retail, Class 7 warehouse, Class 8 factory, or Class 9 healthcare/assembly building.
We service commercial precincts across Sydney — including Fairfield, Liverpool, Cumberland, Canterbury-Bankstown, and Blacktown LGAs, as well as Smithfield, Wetherill Park, Yennora, Prestons, and Arndell Park industrial areas.

Office fit-outs, retail builds, warehouse construction — NCC compliant, fixed price.
NCC Commercial Compliance
Commercial buildings face stricter NCC requirements than residential. Every commercial project Buildana delivers meets these four compliance frameworks:
Section J — Energy Efficiency
Building envelope (insulation, glazing U-values), lighting power density, HVAC system efficiency, and hot water design. Mandatory for all new commercial construction and significant renovations. We coordinate Section J assessments early in design to avoid costly redesigns.
Part D — Accessibility (DDA)
Compliant access paths, accessible toilets, tactile ground surface indicators, hearing loops (Class 9b), and signage. Disability Discrimination Act 1992 applies to all public-facing commercial buildings.
Fire Rating Requirements
Fire-rated walls and floors (FRL varies by class and use), sprinkler systems, smoke detection, emergency lighting, exit signage, fire hydrants and hose reels. Fire engineering reports required for complex buildings.
Section F — Health & Amenity
Ventilation rates, natural light requirements, sanitary facilities, sound insulation between tenancies, and damp-proofing. Requirements differ significantly between commercial classes.
