The context in Collonge-Bellerive
Collonge-Bellerive includes Vésenaz, which serves as the centre with its shops and buildings, and extends along the left bank of the lake in villa districts and large lakeside properties. Shores and natural areas are protected, and the high-end properties expect careful work. At peak hours, the lakeside road concentrates the traffic.

Frequently asked questions
Your questions in Collonge-Bellerive
How long does underpinning in Collonge-Bellerive take?
Two to six weeks depending on the length of wall to rework and the method. The quote describes each item, the planned duration and what is not included.
Is a permit needed for underpinning in Collonge-Bellerive?
A reworking that does not change the volume of the building counts as maintenance, but an engineer’s calculation is essential. A new basement requires a permit that we prepare with you. The details of the procedures are on the website of the State of Geneva, on the applying for a building permit page.
Can you live in the house during the work in Collonge-Bellerive?
Yes, in most cases, the work is done from the outside or from the basement, in small propped passes.
How can you tell whether a crack needs attention in Collonge-Bellerive?
A crack that widens, goes through the wall or comes with a sloping floor calls for an opinion. We install monitoring markers and bring in the engineer.
