Your investment.
Our expertise.
Your control.
Oïkos GPI combines economic analysis, coordination of the design work and management of the works, so that clients (project owners) can make informed decisions, from the first study to handover.

To get straight to the point, tell us who you are:
In ancient Greek, the house one administers.
For the Greeks, the oikos was not only a building: it was the household, the family and the estate to be managed with discernment. From it comes the word “economy”, oikonomia: the art of administering the house.
That is exactly our profession. The client commits their estate to a project. We defend their interests: they decide with full knowledge, know what they are buying and what risk they are taking, and stay in control from start to finish.
What are you looking for?
An investment, not an expense.
Our fees are not added to the cost of your project: they serve to keep it in check. They pay for themselves in the management of your project.
Tenders compared before you sign
Same items, same assumptions, differences explained: you decide on a clear basis.
Changes priced before they are decided
No variation order without a price and deadline approved by you. No surprises at the end of the works.
Subsidies and deadlines secured
A schedule that complies with the subsidy rules, and managed works that do not leave your capital tied up.
Only our fees are invoiced: no commission from contractors, and therefore no interest in pushing one over another. Understand the calculation →
Present your project to us.
A first conversation, without obligation: the address or plot, your objective, an indicative budget.
