Construction project management in Presinge
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 Presinge, one of the smallest municipalities in the canton by population, where more than four residential buildings in ten predate 1946. The firm prepares the plans and the permit application as a registered MPQ agent, then manages the contractors through to completion.
What kind of work in Presinge?
Presinge, a municipality created in 1850, has only 731 residents at the end of 2025 on 471 hectares. The OCSTAT municipal profile puts its density at 155 people per square kilometre, very low for the canton.
The building stock is on the same scale. The cantonal table of buildings records 151 residential buildings at 31 December 2025. 104 are single-family houses, more than two thirds, and 47 hold several dwellings.
What sets Presinge apart is the age of its buildings. 67 predate 1946, more than four in ten, and only 13 were built after 2000. The typical job here is not fitting out a new house. It is restoring an old building, with roof timbers to inspect, a covering to redo, walls to insulate with care and services to replace in full.
In so small a stock, every building is a case of its own. The firm therefore always starts with a full measured survey and condition report.
Permits in Geneva
Two steps come before site work on an old building. First the search for hazardous substances, which the canton covers on its page about renovating, converting or demolishing safely, dealing with asbestos, PCB and lead. Then the building permit, issued by the Office des autorisations de construire (OAC), the cantonal permit office. If the project includes a complete demolition, that requires an application separate from the building application.
Our guide to building permits and procedures in Geneva explains how the file is submitted.

How HMG manages your project in Presinge
If you have no designer yet, HMG takes the project from start to finish, plans and tenders included, and files the permit application as an agent registered on the Geneva MPQ list (mandataires professionnellement qualifiés, the cantonal register of qualified building professionals). If an architect has already drawn the scheme and obtained the permit, HMG comes in after them for construction, and the two work together.
Renovating an old building calls for tradespeople used to this kind of work. The firm chooses them on references, with no financial interest in who is appointed. It sets the order of work, from making the building watertight to the finishes, chairs the site meetings and reports to you on progress and costs at each stage.

Frequently asked questions
How many residential buildings are there in Presinge?
OCSTAT counts 151 at 31 December 2025, of which 104 are single-family houses. 67 of these buildings were built before 1946 and 13 after 2000.
Is a separate application needed for a demolition?
Complete demolition requires an application separate from the building application. The firm prepares both files when the project calls for it.
Can grants be requested for insulating an old house?
Grants from the Programme Bâtiments, the Swiss buildings programme, must be applied for before work starts. The firm builds this step into the study timetable so that the site does not open too early.
