Construction project management in Bardonnex
Planning building work? Apartment, house or building renovation, a new storey or a roof extension, running the project is our job.
In Bardonnex, where more than four residential buildings in ten predate 1946, HMG Construction Management SA manages renovations from start to finish. The measured survey, the plans, the permit application filed as a registered MPQ agent, the budget by trade, the tenders and the running of the site all sit with one firm.
Is the building stock in Bardonnex old?
Largely, yes. Of the 448 residential buildings counted in Bardonnex at 31 December 2025, 200 were built before 1946, more than four in ten, and only 62 after 2000. The data come from the OCSTAT table of buildings.
The municipality has 2,534 residents at the end of 2025 on 500 hectares, according to its statistical profile. Single-family houses are in the majority, though far from the whole picture. There are 267 of them, nearly six buildings in ten, and 181 buildings hold several dwellings. A job in Bardonnex can therefore be a whole house to overhaul, or one home to renovate in an old building shared by several occupants.
The Bardonnex municipal website (in French) lists the council's services.
Permits in Geneva
Two checks are worth planning before renovating a building from before 1946. The first concerns asbestos, PCB and lead, covered by the cantonal page Rénover, transformer ou démolir sans danger (in French). The second concerns the constraints on the plot, through the geo-analysis the canton recommends before filing. The procedure to follow, fast-track (APA) or ordinary (DD), can then be read from the page on permit types. We explain all of it in our guide to building permits and procedures.

How HMG manages your project in Bardonnex
You can come alone or with an architect. Alone, you entrust HMG with the plans, the permit application, filed as an agent registered on the Geneva MPQ list (mandataires professionnellement qualifiés, the cantonal register of qualified building professionals), and everything after. With an architect, you leave design and the permit to them, and HMG runs construction at their side.
Renovating old property calls for method before it calls for contractors. The firm starts by measuring the building and opening up a few points to see what the walls and floors conceal. It then prices the works by trade, organises the tenders and prepares the contracts. On site it checks workmanship every week and makes sure invoices match the work actually done.

Frequently asked questions
What share of buildings in Bardonnex predates 1946?
200 residential buildings out of 448 according to OCSTAT, more than four in ten. Only 62 were built after 2000.
Does an old building cost more to renovate?
The price depends mostly on the real condition of the shell, the roof covering and the pipes and wiring. That is why the firm investigates before pricing. You then decide on a budget set out trade by trade.
Can you renovate a single home in a building that holds several?
Yes. Interior works are then coordinated with the other occupants and, where relevant, with the régie (managing agent) or the PPE (co-ownership). In a residential block, the LDTR, the Geneva housing renovation law, governs alterations to dwellings.
