Construction project management in Gy
Planning building work? Apartment, house or building renovation, a new storey or a roof extension, running the project is our job.
Gy has 582 residents and 144 residential buildings. Even in a municipality of that size, a building project needs drawings, a permit and coordinated contractors. HMG Construction Management SA handles all three, files the application as a registered MPQ agent, prices the works and manages them to SIA standards.
What work in a small municipality like Gy?
With 582 residents at the end of 2025 on 329 hectares, Gy is one of the least populous municipalities on this website. The OCSTAT profile of Gy gives a density of 177 residents per km2. The cantonal count of buildings records 144 residential buildings at 31 December 2025.
Of those 144 buildings, 96 are single-family houses, exactly two in three. 46 were built before 1946, close to a third, and 33 after 2000. Each project is therefore a case of its own, which cannot be handled by comparison with the house next door. In old buildings, the firm looks at the roof and the insulation first. In more recent houses, the request tends to be about fitting out existing space, such as the attic.
The town hall publishes its information on the Gy municipal website (in French).
Permits in Geneva
A private individual may file a fast-track application (APA) in person, but the canton advises going through a registered agent. This is stated on the page Je prépare ma demande d'autorisation de construire (in French), which also recommends a geoanalysis of the constraints on the plot before filing.
That analysis avoids drawing a scheme the plot does not allow. The rest of the route is described in our guide to building permits and procedures in Geneva, together with the permit types provided by the canton.
Types of work in Gy
- House renovation, which concerns two residential buildings in three.
- Attic conversion, to create a room within the existing volume.
- Roof renovation, the first thing to examine on the 46 buildings from before 1946.
- House energy renovation, often carried out together with the roof.
- House extension, once the constraints on the plot have been checked.
How HMG manages your project in Gy
The size of the job does not change the method. If you have no architect, HMG produces the drawings, files the application and runs the works. If you have one, they remain the author of the project and the holder of the permit. The firm then takes over the file and manages the site with them.
For a house project you deal with one person. They visit the building, write the specification, consult contractors and give you a table of the bids. Once the contracts are signed, they set the calendar, come to site every week and record decisions in the minutes. At the end they organise the handover inspection, have defects put right and draw up the final account.
