Construction project management in Pregny-Chambésy

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 Pregny-Chambésy, from the first study to the final account. With no financial tie to contractors, the Geneva firm draws up the plans, files the permit application as a registered MPQ agent, prices the project, selects the contractors with you and runs the site.

Your building work in Pregny-Chambésy

The statistical profile of the municipality, kept by OCSTAT, gives Pregny-Chambésy 4,125 residents at the end of 2025 and 323 hectares, or 1,277 people per square kilometre. The municipality is part of the right-bank sector.

Set against that population, the number of buildings stands out. The cantonal table of buildings counts 1,063 residential buildings at 31 December 2025, one for fewer than four residents, and 824 of them are single-family houses. More than three buildings in four therefore hold a single dwelling.

The stock falls into three generations. 207 buildings predate 1946, almost one in five. 322 were built after 2000, about three in ten. The remaining 534, half of the total, sit between those dates. A house of the first generation needs thorough renovation, roof and facades included. Those of the middle generation call for an energy and services upgrade. The most recent are mainly rearranged inside or given an extra floor.

Permits in Geneva

Before drawing a new storey or an extension, it helps to know what the authority will accept. That is the purpose of the preliminary application, or DP (demande préalable). It obtains an answer on siting, use, envelope, volume and access. The canton also recommends a geo-analysis of the constraints on the plot before filing. Its page on preparing an application is the place to start.

The permit application itself comes next and is presented in our guide to building permits and procedures in Geneva.

How HMG manages your project in Pregny-Chambésy

Some owners come with an architect and an approved scheme. HMG then takes over the file, prepares construction and manages the works alongside them. Others have only the idea so far. In that case HMG takes on the entire project, from plans to handover, and files the permit application as an agent registered on the Geneva MPQ list (mandataires professionnellement qualifiés, the cantonal register of qualified building professionals).

In a villa, finishes and details matter as much as the structure. The firm therefore describes each item precisely in the tender documents, has samples and detail drawings approved before ordering, and checks installation on site. The programme sets the dates of the decisions that fall to you, so that choosing a material never holds up a contractor.
