Is this a contractor quotation?
No. DSGNBRF provides an early-stage planning estimate. Final pricing should be confirmed after the design and project scope are developed and contractors or cost consultants have reviewed the project.

Whether you are taking a new office, relocating or refurbishing an existing workplace, the fit-out budget can vary significantly depending on size, specification and starting condition. Use DSGNBRF to establish an early-stage planning range before progressing to detailed design and quotations.

Enter a few project details to generate an indicative low-to-high planning range.
Planning estimate only. Final project cost depends on design, scope, site conditions, procurement, statutory requirements and market pricing.
Office budgets depend on much more than floor area. Starting condition, partitioning, meeting-room requirements, acoustic performance, ceilings, flooring, joinery, lighting, workplace technology and alterations to building services all influence the scope.
Reusing suitable partitions, ceilings or services can create a very different project from fitting out a largely unfinished unit. Before relying on any cost-per-area comparison, understand the handover condition and what can realistically be retained.
Before detailed budgeting, establish the number of people, workspace requirements, meeting rooms, support spaces, pantry requirements, technology needs and intended finish level. These decisions help convert an approximate fit-out allowance into a meaningful project brief.
DSGNBRF selects the relevant available benchmark for the chosen country, location, project type and specification. The applicable project area is then used against the benchmark range to produce an indicative low-to-high project cost.
The calculator does not automatically average unrelated sources or apply arbitrary city, access, floor or basement multipliers. Separate costs are included only where they are explicitly supported by the calculator methodology.
Construction and fit-out budgets often contain costs outside the core benchmark. Unless specifically included by the selected benchmark or entered separately, the DSGNBRF estimate may exclude professional consultant fees, authority and statutory charges, utility connections, landlord deposits, financing and legal costs, VAT or GST, loose furniture, specialist equipment, IT hardware and other project-specific expenditure.
Always review the calculator result and exclusions before using the estimate as a project budget.
No. DSGNBRF provides an early-stage planning estimate. Final pricing should be confirmed after the design and project scope are developed and contractors or cost consultants have reviewed the project.
It is useful for initial feasibility, but the area basis, scope, specification and exclusions must also be understood.
Not necessarily. Review the inclusions and exclusions shown with your result. Professional fees, statutory costs, specialist equipment and other project-specific costs may need to be budgeted separately.
Accuracy depends on the quality and relevance of the available benchmark and the amount of project information known. DSGNBRF therefore presents a planning range and confidence context rather than a guaranteed price.
