Short answer
Construction is only part of the answer. Design, documentation and approvals all happen before any work starts on site, and that pre-construction phase regularly takes longer than owners expect. A reliable timeframe becomes possible once the design is settled, approvals are in hand and the contract is signed, which is the point at which a builder can commit to a real programme.
The work before construction
The project begins with the brief, site investigations and design. The time needed depends on how resolved your ideas are, the complexity of the block, the number of design revisions and how quickly decisions can be made. Surveying, soil information, engineering and early cost checks all help turn the concept into a buildable proposal.
Selections also matter. Windows, external materials, joinery, fixtures, appliances, heating and cooling and other major items need to be coordinated with the drawings and budget. Leaving important choices unresolved can delay documentation, pricing and ordering later.
Approvals and project preparation
The approval pathway depends on the type of development. A project that requires development approval must be assessed through that process before the building approval and commencement requirements are completed. Requests for further information or design changes can add time, especially when several consultants need to respond.
Contract preparation, finance, demolition and the ordering of products with longer lead times also sit between design and active construction. These tasks can overlap when the information is ready, but they should not be rushed at the expense of clear documents or a properly understood price.
The construction programme
Once construction starts, the work follows a sequence. Site preparation and foundations come first, followed by the frame, roof, windows and external enclosure. Services are installed, internal linings and joinery follow, then waterproofing, tiling, painting, flooring, fit off, testing and final completion.
Each trade depends on work completed before it. A delay in one critical area can affect several activities that follow, while good planning allows other work to continue. The programme also needs to accommodate required inspections and the safe coordination of everyone working on the site.
What can change the timing
Weather, unexpected ground conditions, authority requests, product availability and trade sequencing can all influence the programme. Client requested changes during construction can also affect both time and cost, particularly when completed work or confirmed orders need to be altered.
The building contract should explain the timing basis for the work and the circumstances in which an extension may be allowed. A realistic programme includes the known sequence and lead times while recognising that some matters are outside the direct control of the owner and builder.
When the timeframe becomes clearer
An early conversation can provide a broad indication, but a more reliable timeframe comes after the design, site investigations, approval pathway, major selections and scope have been properly considered. That is when the builder can plan the work against real information rather than assumptions.
