Construction project management in Confignon
Planning building work? Apartment, house or building renovation, a new storey or a roof extension, running the project is our job.
In Confignon, where more than seven residential buildings in ten are single-family houses, HMG Construction Management SA manages your building work. The firm has no financial tie to any contractor and has them compete against a set budget. It also files the permit application as an agent registered on the Geneva MPQ list (mandataires professionnellement qualifiés, the cantonal register of qualified building professionals).
What kind of work in Confignon?
Confignon is a municipality created in 1851, with 4,570 residents on 277 hectares at the end of 2025. Its density reaches 1,649 inhabitants per km², according to its OCSTAT profile. Turning to the buildings, the OCSTAT table of buildings with dwellings records 815 residential buildings, with 583 single-family houses and 232 buildings of several dwellings.
Buildings from after 2000 (183) outnumber those from before 1946 (120), and most of the stock falls between the two periods. These are often houses where the kitchen, the bathrooms, the heating and the insulation all wear out at about the same time. Dealing with them in a single project causes less disruption than taking them one by one. The Confignon municipal website provides local information.
Procedures in Geneva
Changing the room layout is an interior alteration to an existing building, which the cantonal page on permit types places under the fast-track procedure (APA). If the works touch older materials, the page Rénover, transformer ou démolir sans danger (in French) deals with asbestos, PCB and lead ahead of the works. On the energy side, Programme Bâtiments grants must be applied for before work begins. Our guide to procedures for works in Geneva brings these points together.

How HMG manages your project in Confignon
You choose the starting point. Without an agent, you give HMG the plans, the permit application and everything that follows. With an architect, they design the project and obtain the permit, after which HMG takes over the file and manages the works at their side.
HMG starts with a realistic budget, built up item by item, which you approve before tendering. Contractors are chosen on comparable bids. The site follows a schedule that allows for your presence in the house, and the firm checks every interim payment application before it is paid. The final account is set against the opening budget.

Frequently asked questions
How many single-family houses are there in Confignon?
OCSTAT counts 583 at the end of 2025, out of 815 residential buildings. The other 232 hold several dwellings.
Is it better to renovate everything at once?
When several elements need renewing, a single project avoids redoing the same finishes twice. HMG prices both scenarios, all at once or in stages, so that you can decide according to your budget.
Can we live in the house during the works?
In many cases, yes. HMG organises the site by zones and provides a temporary kitchen and washroom if needed. During some of the heavier phases you may need to move out for a short while.
