Construction project management in Jussy
Planning building work? Apartment, house or building renovation, a new storey or a roof extension, running the project is our job.
More than half of the residential buildings in Jussy date from before 1946. HMG Construction Management SA manages their renovation and conversion. The Geneva firm draws up the plans, files the permit application as a registered MPQ agent, works out the cost, appoints the contractors and supervises the works to SIA standards.
Why does work in Jussy mostly concern old buildings?
The figures answer the question. The municipal profile of Jussy gives 1,256 residents at the end of 2025 on 1,135 hectares, or 111 residents per km2, a low density. The cantonal table of residential buildings counts 304 buildings at 31 December 2025. Of these, 158 were built before 1946, more than one in two. Only 42 postdate 2000, about one in seven.
There are 173 single-family houses, a little over half the stock. The other 131 buildings hold several dwellings. In Jussy, renovating therefore most often means improving a building that already has a long life behind it. Energy use, the state of the roof structure and the way dwellings share one volume are the subjects that come up.
Municipal information is on the official Jussy website (in French).
Permits in Geneva
For an energy renovation, the CECB+ certificate describes the state of the building and proposes renovation options. It is the basis for choosing the works. Grants from the Programme Bâtiments, the Swiss buildings programme, have to be requested before the works start, which means fixing the calendar very early.
The permit side is explained in our guide to building permits and procedures in Geneva. Permits are issued by the Office des autorisations de construire, the cantonal building permit office.

How HMG manages your project in Jussy
The starting point is up to you. Either you entrust everything to HMG, and the firm prepares the plans and the permit application before organising the site. Or you already work with an architect. They then take the project up to the permit, and HMG takes over the file to build it, in collaboration with them.
An energy renovation involves several trades that depend on one another, from the roof covering to the heating by way of the windows. The firm sets the order of the interventions, writes the filing of grant requests into the schedule ahead of the start on site, then coordinates the contractors week after week. You receive a cost statement that separates what is committed, invoiced and paid.
