A site can look ideal on a sales listing and still carry a boundary discrepancy, an unbuildable drainage constraint or a planning control that changes the numbers completely. The best land development feasibility checks establish what can realistically be built, subdivided or retained before you commit to a purchase, design fees or a planning strategy.
For Victorian projects, feasibility is not one report or one conversation with council. It is a coordinated review of the title, physical site conditions, planning controls, servicing and likely approval pathway. The purpose is straightforward: identify constraints early enough to change the proposal, renegotiate the purchase price or walk away with confidence.
Start with the title, boundaries and legal interests
A current title search is the starting point, but it should not be treated as proof that the land can be developed as intended. The title, plan of subdivision and any associated instruments need to be reviewed for easements, restrictive covenants, agreements, caveats and other encumbrances that may limit building location, access or subdivision potential.
Easements are a common issue. A drainage or sewerage easement may prevent building over part of the land, require authority consent, or force a redesign of garages, driveways and private open space. A covenant can be more restrictive still, particularly on older estates, where it may limit the number of dwellings, materials or the type of construction permitted.
A re-establishment survey provides the on-ground certainty that desktop title review cannot. It marks the legal boundaries and identifies whether fences, sheds, retaining walls or neighbouring structures sit where they are expected to. This matters before finalising layouts near side boundaries or relying on an assumed width for a dual-occupancy driveway.
Do not assume a fence is the boundary. In established Melbourne suburbs, fences can be offset, replaced over time or built for practical rather than legal reasons. Resolving that issue after a design has been lodged is far more expensive than checking it at the feasibility stage.
Best land development feasibility checks for the site
The physical characteristics of the land determine whether a concept is practical, not merely attractive on a plan. A detailed feature and levels survey gives the project team reliable information on contours, existing buildings, trees, kerbs, crossovers, drainage points, visible services, neighbouring features and site levels.
Accurate levels are particularly important where the site falls towards a rear boundary, a low point or a drainage reserve. They influence cut and fill, retaining requirements, finished floor levels, stormwater design, vehicle grades and accessibility. A modest slope can be manageable; a site with significant fall or difficult drainage may change construction costs enough to undermine the feasibility.
The site review should test the following matters together rather than in isolation:
- Topography, overland flow paths and the likely stormwater discharge point.
- Existing structures, significant vegetation and potential demolition constraints.
- Vehicle access, frontage width, crossover opportunities and sight lines.
- Adjoining development, overlooking interfaces, party walls and overshadowing sensitivity.
- Apparent services, poles, pits and assets that may affect building siting or construction.
Flooding requires specific attention. Council flood overlays, Melbourne Water mapping and local drainage conditions may impose minimum floor levels, storage requirements or design responses. Even where a property is not formally mapped as flood-prone, a low-lying site can present overland flow issues that need to be addressed in the development design.
For larger or previously commercial sites, early investigation of ground conditions and potential contamination may also be warranted. The appropriate level of investigation depends on past land use, the proposal and the planning controls. It is not necessary to commission every technical report before purchase, but known risk indicators should be allowed for in the due diligence budget and programme.
Check planning controls before testing yield
A yield calculation is only useful when it is based on the planning scheme that applies to the land. Check the zone first, then every relevant overlay and particular provision. In Victoria, this may include heritage, vegetation, flooding, bushfire management, environmental significance, design and development, or development contributions controls.
The planning review needs to go beyond a simple question of whether multiple dwellings are permitted. It should consider the likely built form outcome: setbacks, site coverage, permeability, private open space, building height, overlooking, overshadowing, car parking, bicycle parking, landscape requirements and waste collection. On a constrained infill site, one additional dwelling on a concept plan may be the difference between a viable project and an unworkable application.
Council policy and local character expectations also matter. A proposal may technically fit within a zone yet require substantial design work to respond to neighbourhood character, preferred building scale or heritage context. This does not mean development is impossible. It means the feasibility should include an honest allowance for the time, consultant input and potential design compromise required to obtain a permit.
For subdivisions, consider whether the proposed lots will function independently after registration. Each lot needs workable access, services, drainage, dimensions and an appropriate relationship to existing and future buildings. Creating a narrow residual lot with limited vehicle access can produce a plan that looks efficient but is difficult to sell, build on or finance.
Confirm servicing and infrastructure capacity
Water, sewer, drainage, electricity, gas and telecommunications are not administrative details to leave until construction. Their location and capacity can materially affect project cost and timing.
Check whether there is a suitable sewer connection point, whether drainage can be legally discharged, and whether existing assets cross the development area. A proposed dwelling may need a new connection, an extension, a pump system or authority approval to build near an asset. Electricity supply upgrades and relocation of poles or pits can also be significant, especially where a development increases demand or changes site access.
The best approach is proportionate. For a straightforward two-lot subdivision, preliminary authority information and a survey-based review may be enough to identify the main risks. For a townhouse, commercial or greenfield project, servicing investigations should be more detailed and integrated with civil, hydraulic and electrical advice.
Allow for public infrastructure requirements as well. New crossovers, footpath works, drainage upgrades, street tree protection, road widening or developer contributions can arise through planning permit conditions or authority requirements. These costs are project-specific, but they should not be treated as contingencies without first understanding the likely trigger.
Test the approval pathway, programme and risk
Feasibility is partly a time assessment. A project that produces an acceptable end value may still be unattractive if approvals, referrals, servicing works and title registration push settlement or construction beyond the intended funding period.
Map the likely sequence: survey and concept design, pre-application discussions where useful, planning permit, endorsed plans, subdivision certification, servicing authority approvals, statement of compliance and title registration. Not every project follows every step, but identifying the pathway early helps avoid unrealistic expectations.
Referral authorities can affect both timing and design. Depending on the site, an application may involve water authorities, road authorities, heritage bodies, bushfire considerations or other agencies. The issue is not simply whether a referral will occur; it is whether the proposal has allowed for the authority’s technical requirements from the outset.
A planning permit and a subdivision outcome are also different milestones. Where new titles are required, the project must satisfy the conditions needed for certification and statement of compliance before plans can be registered. Developers should carry this timing through their feasibility model rather than assuming titles will issue when construction is complete.
Put the numbers against a realistic concept
The final check is commercial, but it should be based on evidence from the earlier work. Model the likely yield, sale or rental assumptions, acquisition costs, consultant fees, authority charges, demolition, construction, finance, holding costs and contingency. Then test a lower-revenue and higher-cost case.
The key question is not whether the site supports the maximum theoretical yield. It is whether it supports a design that can be approved, serviced, built and sold or retained at an acceptable margin. Sometimes a lower-density proposal offers a clearer permit pathway, simpler construction and a better overall return.
For first-time developers, this is where coordinated advice has real value. Surveying, planning and subdivision decisions are interconnected, and an early error can flow through every later stage. Melbourne Land Surveyors can help establish the surveyed site information and development pathway needed to make decisions on sound ground.
Before signing a contract or allowing a cooling-off period to expire, make the feasibility checks match the scale and risk of the project. A measured upfront investigation is not an added hurdle – it is often the work that protects the project from becoming an expensive assumption.
