Financing a construction project: every lever

📐 Topic5 min read

Financing is often addressed too late in the life of a project. Yet the financial structure of an operation should be thought through at the feasibility stage, alongside the first programme studies. A technically perfect but financially ill-structured project will never be built, or will be built at the price of painful compromises.

This page sets out the financing levers available for construction projects: how they work, the conditions of access and their specific constraints.

What you will learn

  • The families of finance available for a construction project
  • How the development loan works and how it is obtained
  • The public grants and subsidies available by project type
  • Property crowdfunding: how it works, its opportunities and its risks
  • How to build and present a solid funding plan

The families of finance

Every construction project must mobilise resources sufficient to cover all its expenditure. Those resources can come from several sources, generally combined.

Equity

Equity is the operator's own or corporate contribution. It is the basis of all financing: no bank will fund a project without a significant contribution. In housing, banks generally require 20 to 30 % of the total cost. In development that ratio can fall to 10–15 % with a high level of pre-sales.

Classic bank credit

For private individuals, the classic mortgage is the dominant route, granted over 15 to 25 years. For professional clients outside development, authorities, social landlords, companies, specific loans exist: balance-sheet loans, European investment bank finance, and loans from the state deposit institution.

The development loan

The development loan is short-term finance, 12 to 36 months, structured specifically for property development operations. It covers the delivery phase of the project, from planning permission to handover and repayment from sales.

Typical conditions for a development loan

Criterion Condition
Minimum pre-sales 40 to 50 % of turnover signed off-plan
Equity 10 to 20 % of the total cost
Rate A margin of 1.5 to 3.5 % over the interbank rate according to the bank

A completion guarantee is mandatory for off-plan sales.

Public grants and subsidies

Public authorities offer a range of financial support for certain types of construction project. It can take the form of direct grants, subsidised loans, tax relief or guarantees.

Social housing Subsidised loans from the state deposit institution at 1 to 3 %, central and local grants, VAT reduced to 5.5 %.
Energy retrofit The national retrofit grant, energy saving certificates and the zero-interest loan for private individuals; the housing agency's schemes for landlords.
Public buildings State equipment grants and European funds for eligible projects.
Environmental labels Low-energy and carbon labels give access to preferential finance and to development bonuses.
Priority areas Specific support for projects within urban renewal perimeters.

Property crowdfunding

Property crowdfunding has grown strongly since 2012. It lets developers raise funds from private investors through platforms authorised by the financial markets regulator.

The operator presents the project on the platform. Investors lend sums remunerated at 8 to 12 % a year over 12 to 36 months. The funds are repaid at the end of the operation, on sale.

Advantage for the operator A rapid supplement to equity without dilution or a new partner in the governance.
Advantage for the investor An attractive yield, an accessible entry ticket, diversification across several projects.
Principal risk Partial or total loss of capital if the operator defaults.
Condition of success A solid development appraisal, advanced pre-sales, a demonstrated track record.

Building a solid funding plan

The quality of the funding plan presented to financial partners directly governs the borrowing terms obtained. A good plan rests on four elements:

  • A realistic appraisal: income and expenditure detailed and documented against market references.
  • A precise calendar: pre-sales milestones, drawdown and repayment dates.
  • A risk analysis: the principal risks identified and the mitigation planned.
  • The operator's track record: references from similar operations delivered, and the accounts of the carrying entity.

The loan-to-value ratio: the banker's key indicator It measures the ratio between the loan sought and the total cost of the project. A ratio of 70 % means the bank funds 70 % and the operator brings 30 % in equity. In a context of higher rates, banks tend to require more conservative ratios than in a low-rate period.
