Construction project management in Plan-les-Ouates
Planning building work? Apartment, house or building renovation, a new storey or a roof extension, running the project is our job.
HMG Construction Management SA manages building work in Plan-les-Ouates, where close to three residential buildings in four are single-family houses. The firm draws up the plans, files the permit application as a registered MPQ agent, works out the cost, appoints the contractors and runs the site to SIA standards.
What kind of work in Plan-les-Ouates?
Plan-les-Ouates, a municipality created in 1851, has 12,700 residents at the end of 2025 on 585 hectares according to the OCSTAT profile of the municipality. Density stands at 2,170 people per square kilometre.
The cantonal table of buildings lists 1,842 residential buildings there at 31 December 2025, including 1,371 single-family houses. The house clearly dominates, at close to three quarters of the stock. The other striking fact is the share of recent construction. 542 buildings went up after 2000, almost three in ten, against 305 before 1946.
Two situations follow. There is the recent, sound villa that its owners want to extend, rearrange or fit with a new kitchen. And there is the older house, where roof, windows and heating come first. Between the two, the 995 buildings from 1946 to 2000 make up more than half the stock, and many are due an energy renovation.
The official Plan-les-Ouates website (in French) gives information on municipal services.
Permits in Geneva
Building rules, including those of the fifth zone, the villa zone, are set by the LCI, the Geneva law on buildings and installations. According to the cantonal page on permit types, building in the fifth zone without a derogation can follow the fast-track procedure, known as APA. The zoning of your plot is checked at the start of the study.
The rest of the route is in our guide to building permits and procedures in Geneva.

How HMG manages your project in Plan-les-Ouates
For a villa, there are two set-ups. You can appoint HMG for everything, with feasibility study, plans and construction, and the permit application filed as an agent registered on the Geneva MPQ list (mandataires professionnellement qualifiés, the cantonal register of qualified building professionals). Or you have the scheme designed by an architect, who obtains the permit, and HMG takes on the management of the works from there, in close cooperation with them.
The firm starts with a detailed cost estimate, so that you know whether the project fits your budget before going further. It then issues tenders, negotiates, prepares the building contracts and fixes the programme. During the works it checks quality, keeps the cost statement up to date and organises acceptance with the snagging list.
