Construction project management in Le Grand-Saconnex
Planning building work? Apartment, house or building renovation, a new storey or a roof extension, running the project is our job.
In Le Grand-Saconnex, a municipality of 12,481 residents where single-family houses and apartment buildings sit side by side, HMG Construction Management SA manages your building work. The Geneva firm draws up the plans, files the permit application as a registered MPQ agent, sets the budget, chooses the contractors and runs the site to SIA standards.
House or apartment building, what work in Le Grand-Saconnex?
Le Grand-Saconnex has 12,481 residents at the end of 2025 on 438 hectares, according to its municipal profile published by OCSTAT. Density stands at 2,848 residents per km2. At 31 December 2025, OCSTAT table T 09.02.1.2.01 records 1,150 residential buildings.
Two thirds of them, 767, are single-family houses. The last third, 383 buildings, holds several dwellings. The firm therefore receives two quite different kinds of request here, from the owner of a house and from the owner or tenant of an apartment. The stock is also fairly young. 348 buildings were put up after 2000, about three in ten, almost twice the 181 buildings from before 1946.
Municipal formalities are set out on the official website of Le Grand-Saconnex (in French).
Permits in Geneva
The rule changes with the building. In a residential block, work inside the dwellings is governed by the LDTR, the Geneva law on demolition, conversion and renovation of housing. In a house, the main text is the LCI, the cantonal building act, with its construction rules.
In both cases the permit is requested from the cantonal building permit office, the OAC. Our guide to building permits and procedures in Geneva shows when the fast-track procedure is enough and when a full application is required.

How HMG manages your project in Le Grand-Saconnex
The appointment fits your situation. Without an architect, you hand everything to the firm, which draws up the plans and the permit application before managing the works. With an architect, they keep the design and the permit, and HMG takes over the file for the construction phase, working with them.
In an apartment, the firm first settles with the régie (managing agent) or the PPE (condominium) whatever affects the common areas and the service risers. In a house, it starts with the state of the envelope and the installations. The rest is the same. Contractors are consulted on a shared specification, their bids are compared, the contracts fix prices and deadlines, and every invoice is checked before payment.

Frequently asked questions
Are there more houses or apartment buildings in Le Grand-Saconnex?
By number of buildings, single-family houses are in the majority. OCSTAT counts 767 of them out of 1,150 residential buildings, which is two thirds. The other 383 buildings hold several dwellings.
Do you need the managing agent's consent to redo a kitchen?
If you are a tenant or a co-owner, the régie or the PPE has to be involved in the project. The firm prepares the technical file to submit and checks whether a cantonal permit is needed.
Does a recent home need project management?
Yes, as soon as several contractors are involved. Even for an interior fit-out, the trades have to be coordinated, the schedule kept and the costs checked. That is the firm's role.
