Construction project management in Céligny
Planning building work? Apartment, house or building renovation, a new storey or a roof extension, running the project is our job.
HMG Construction Management SA manages building work in Céligny, where over half of the residential buildings predate 1946. The firm draws up the plans, files the permit application as an agent registered on the Geneva MPQ list (mandataires professionnellement qualifiés, the cantonal register of qualified building professionals), prices the works, appoints the contractors and runs the site to SIA standards.
What kind of work in Céligny?
Céligny has 839 residents on 465 hectares, or 180 inhabitants per km², according to the municipal profile published by OCSTAT, the cantonal statistics office. The cantonal table of residential buildings lists 217 of them at the end of 2025. Of these, 155 are single-family houses and 126 were built before 1946. Only 33 were built after 2000.
The figures describe a stock of older houses. A project here nearly always starts with a measured survey, followed by a search for hazardous substances before anything is taken apart. The roof, the facades and the energy use come next, and they weigh heavily in the budget of a house of that age. For municipal matters, the official Céligny website is the place to start.
Procedures in Geneva
In an older house, the survey for hazardous substances comes before everything else. The cantonal page Rénover, transformer ou démolir sans danger (in French) covers asbestos, PCB and lead before works. The permit is then issued by the Office des autorisations de construire (OAC), the cantonal permit office. An interior alteration to an existing building goes through the fast-track procedure, known as APA, and whatever falls outside it requires a full application, known as DD. Our guide to building permits and procedures in Geneva sets out each route.

How HMG manages your project in Céligny
You can hand the whole project to HMG. The firm surveys the house, draws up the plans, files the permit application, prices each trade and appoints the contractors. If you already work with an architect, they keep the design and the permit, and HMG then takes over the file for the construction phase, working alongside them.
In an old building, surprises turn up when walls and floors are opened. HMG deals with them at the site meeting, has any change priced before it is carried out and keeps the schedule up to date. The firm is independent, with no financial tie to any contractor, and it checks the invoices before payment.
Municipalities in the same sector
