What is the building stock in Choulex?
Choulex is a small municipality of 1,245 residents on 391 hectares, or 319 inhabitants per km² according to its cantonal statistical profile. At the end of 2025, the OCSTAT count of residential buildings lists 311 buildings, 216 of them single-family houses. More than four buildings in ten predate 1946 (142), while only 47 were built after 2000.
The share of old buildings steers projects towards upgrading. Insulating without damaging the walls, renewing a roof covering, replacing a heating system, creating rooms inside an existing volume, these are the requests one would expect from a stock of this age. Before that, a survey for hazardous substances prevents a stoppage on site. The Choulex municipal website is the source for local information.
Procedures in Geneva
An energy renovation is prepared with a CECB+ certificate, which describes the energy condition of the building and the renovation options. Grants from the Programme Bâtiments have to be requested before the works start, so the timetable must be set early. Works that do not alter the general appearance of the building fall under the fast-track procedure, called APA. Our guide to procedures for building work in Geneva puts these steps in order.
Types of work in Choulex

How HMG manages your project in Choulex
There are two ways of working. HMG can take on everything, from the survey of the house to the final account, with the plans and the permit application. The firm can also step in once your architect has obtained the permit, and manage construction alongside them.
For an old house, HMG arranges opening-up works before tendering, so that contractors price a job they can see. Bids are compared line by line. During the works, the firm checks the workmanship, keeps the minutes and flags every cost variation before it is committed.

Frequently asked questions

Often, from the inside, through the roof or by replacing the windows. HMG compares the options with their cost and their effect, then leaves the choice to you.
