Construction project management in Genthod
Planning building work? Apartment, house or building renovation, a new storey or a roof extension, running the project is our job.
Are you preparing building work in Genthod, where 734 of the 835 residential buildings are single-family houses? HMG Construction Management SA takes care of it. The firm draws up the plans, files the permit application as a registered MPQ agent, works out the cost, appoints the contractors and manages the site to SIA standards.
What does work in Genthod usually involve?
Genthod lies in the right bank sector of the canton. According to the statistical profile of Genthod, 2,858 people live there at the end of 2025 on 287 hectares, a density of 995 residents per km2. The OCSTAT table of buildings by municipality lists 835 residential buildings at 31 December 2025, of which 734 are single-family houses. That is close to nine in ten.
Construction periods are spread fairly evenly. 170 buildings predate 1946, about one in five. 202 were built after 2000, close to a quarter. The remaining 463 went up between those two dates. The request therefore almost always concerns a villa, but the content of the work varies widely with its age, from a single bathroom to a complete new roof.
For municipal services, see the Genthod municipal website (in French).
Permits in Geneva
Before an extension or a new build, you can put the question to the authorities through a preliminary application, called DP (demande préalable). The answer covers the siting, the intended use, the height and outline, the volume and the access of the project. The permit types are described on the cantonal website.
The file is then prepared online on the AC-Démat platform, in a free personal account, as explained on the page Je prépare ma demande d'autorisation de construire (in French). Our guide to building permits and procedures in Geneva goes through these steps.

How HMG manages your project in Genthod
There are two set-ups. In the first, HMG is your single point of contact from the first drawing to the final account. In the second, your architect designs the villa or its extension and obtains the permit. HMG then takes over the file and manages the works alongside the architect.
Many owners stay in their house during the works. The firm then splits the job into zones and stages so that a kitchen and a bathroom remain in use. The dated schedule is issued before work begins and updated after each weekly meeting. Contractors' invoices are checked against the contracts before they are passed to you for payment.

Frequently asked questions
Is Genthod a municipality of villas?
The figures say so. OCSTAT counts 734 single-family houses out of 835 residential buildings at 31 December 2025. Only 101 buildings hold several dwellings.
What is a preliminary application for?
It obtains an answer from the authorities on the siting, intended use, height and outline, volume and access of a project. You learn whether an extension is feasible before paying for full drawings.
Can you live in the villa during the works?
Often, yes. The site is then organised in zones so that the essential rooms stay usable. Heavy structural or roofing work may still require a temporary move.
