The mandate
The sponsor needed a single view of a high-end condominium project aimed at the ultra-prime London market. The commercial question was not simply whether projected sales exceeded cost, but how the timing of land, construction, professional fees and unit completions affected peak funding and investor returns.
The engagement therefore focused on producing an auditable development appraisal that could be reviewed by the sponsor and prospective capital partners. Client and property identities remain confidential, and no deal value or realised return is disclosed.
How the model was structured
The model linked a development programme to a detailed cost plan and monthly cash flow. Residential sales were driven by unit mix, selling-price assumptions and absorption timing rather than a single top-down revenue number. Construction and soft costs followed the programme, allowing delay and cost-overrun cases to be assessed consistently.
Financing logic tracked equity contributions, debt drawdown, interest and repayment. Project-level profit, levered and unlevered returns and peak cash requirement flowed from the same assumptions. A partner distribution waterfall then allocated available cash across the agreed investor stages, giving each party visibility over the effect of timing and performance.
Sensitivity tables tested the variables most likely to change the decision: achievable sales values, construction cost, sales pace and programme delay. Visible checks reconciled sources and uses, cash balances and total distributions.
How the model supported the decision
The completed workbook gave the sponsor a consistent basis for capital discussions and scenario review. Instead of circulating separate cost, sales and return schedules, the team could change one assumption and see its effect throughout the project and partner economics.
The model's role was decision support: clarifying the funding profile, exposing downside cases and presenting the distribution mechanics in a form that external reviewers could follow. It did not replace technical, tax, valuation or legal advice.
For review meetings, the workbook also gave stakeholders a shared vocabulary for base, downside and delay cases. That reduced ambiguity about which assumptions had changed and kept the construction programme, funding schedule and partner waterfall aligned during successive iterations of the appraisal.
