The Development
Playbook

Free checklist

Check the development case before you open the model.

A pre-feasibility checklist for deciding whether a site has enough evidence to justify full modelling, design work, or investment committee time.

Purpose

A quick gate, not a full model.

The checklist is meant to slow down false certainty. It asks for enough evidence to identify whether the site should move to modelling, redesign, renegotiation, or a clean no.

Best used before

Land offer / IC memo / design brief

Five feasibility gates

The minimum useful question set

01

Site capacity

Can the site physically and legally hold the development being imagined?

  • Plot size and boundaries
  • Access, frontage, slope, and services
  • Planning controls, setbacks, parking, and height
  • Gross-to-saleable efficiency range

02

Market evidence

Is there enough demand evidence to support the proposed product, price, and absorption?

  • Comparable sale or rental evidence
  • Buyer or tenant profile
  • Competing supply and active pipeline
  • Realistic absorption or lease-up pace

03

Cost reality

Are the cost assumptions specific enough to avoid a false positive?

  • Construction cost per m² benchmark
  • Professional fees and statutory costs
  • Infrastructure, utilities, and abnormal works
  • Contingency and escalation allowance

04

Capital path

Can the project survive the timing of cash out before cash comes back?

  • Land payment terms
  • Pre-construction and approval timeline
  • Debt drawdown conditions
  • Peak equity requirement and funding source

05

Return threshold

Does the development still work after margin, risk, and downside sensitivity?

  • Profit on cost and margin on GDV
  • Residual land value or land value support
  • Price and cost sensitivity
  • Go / pause / redesign decision

Evidence register

The checklist asks for proof, not confidence.

The useful move is not to make every answer perfect. It is to show which assumptions are evidenced, which are provisional, and which are doing dangerous work.

Title / ownership

Copy of title, ownership trail, encumbrances, land rent/rates status.

Planning

Zoning, permissible use, density, parking rules, approvals pathway.

Area schedule

Early GFA, NSA, parking, common areas, and efficiency assumptions.

Pricing

Comparable asking and achieved prices, age of comps, location adjustment.

Cost

QS benchmark, contractor benchmark, recent comparable project, escalation view.

Programme

Approvals, design, procurement, construction, sales or lease-up timeline.

Capital

Equity source, debt terms, pre-sale rules, interest rate, fees, repayment logic.

Red flags

Signals that the project needs a pause.

01

The model needs a premium price but the product is ordinary.

02

The land value only works if construction cost stays perfectly flat.

03

Efficiency is assumed before the architect has tested parking, cores, and services.

04

Debt is assumed before pre-sale or covenant conditions are understood.

05

The strongest sensitivity case is described as the base case.
