A landscaper in Cologny works on plots where the slope, the view and mature trees shape the project: tiered terraces, retaining walls, a pool facing the lake, planting that gives the property its structure.

The terrain in Cologny: what to know before starting a project
Cologny sits on the hillside overlooking the lake and the harbour, opposite the city. This setting gives properties their main asset, the view, but it also brings constraints: many plots are sloping, sometimes steeply, and any landscaping must deal with the change in level before aesthetics come into play.
Hamlets and localities such as Ruth, La Belotte or the Vallon offer contrasting conditions. On the upper hillside the exposure is generous but the wind can be felt, especially during episodes of the bise. Lower down, towards the Vallon, the ground can hold more moisture. Geneva soils are often clay: they retain water in winter, crack in summer and call for carefully designed drainage behind a wall or beneath a terrace.
The area has large properties with lake views, wooded parks and long-established gardens. A project must therefore take account of existing trees, their roots and their shade, and respect the character of a place where the Villa Diodati, linked to the stay of Lord Byron and Mary Shelley in 1816, and the Fondation Martin Bodmer bear witness to a heritage worth protecting. Successful landscaping here blends into the setting rather than imposing itself.
Landscaping projects in Cologny
Terraces and levels on sloping ground
On a hillside, gaining flat space is the first step towards enjoying the garden. A landscaper creates successive levels linked by steps or ramps, oriented towards the lake. The choice between a timber or stone terrace depends on exposure, use and the style of the house. Drainage and foundations are decisive: on clay soil, they determine how well the structure lasts over time.
Retaining walls and gabions
As soon as a plot is levelled, the earth has to be held back. Gabions and retaining walls structure the different levels while letting water drain through. Stone-filled cages blend well into wooded gardens and can be planted. Their sizing depends on the height to retain, the nature of the soil and the water running off the land above.
Pools and water features with lake views
A pool, pond or water feature works best when it follows the terrain rather than fighting it. In Cologny, the challenge is often to align the water with the view, to take care over the surroundings and to control the earthworks. The landscaper coordinates the siting, coping, sun decks and neighbouring planting so that the whole looks coherent from the house and from the garden.
Lighting paths through the design
In a sloping park, steps and paths must stay safe in the evening. As part of a landscape design, the layout of paths and the position of steps, low walls and beds are planned to accommodate lighting: discreet path markers, light points built into masonry, and highlights on remarkable trees. The aim is to guide without dazzling and to preserve the evening atmosphere.
Structural planting
Garden creation in Cologny relies on planting that adds depth: well-formed trees, informal or clipped hedges, and shrub beds that close or open up views. The idea is to frame the view of the lake, shelter from wind and prying eyes, and stabilise slopes with deep roots. Species are chosen with their mature size in mind, so the garden stays well proportioned in ten or twenty years.
Irrigation for sloping gardens
On a hillside, water runs off quickly and the upper areas dry out more than the lower ones. An automatic irrigation system designed in zones, according to exposure and plant needs, avoids waste and protects new planting during dry summers.
Suitable materials and plants
For structures, natural stone suits walls, steps and pool coping: it ages well and sits comfortably alongside older buildings. Timber, chosen for its durability, adds warmth to terraces and pergolas. Stabilised gravel provides permeable paths that are less affected by runoff than a sealed surface, while asphalt remains useful for driveways. Metal, as railings, gates or fence frames, offers slim lines that preserve the view.
As for plants, the Lake Geneva climate, mild but marked by the bise and sometimes dry summers, favours hardy, low-water species: grasses, Mediterranean perennials, shrubs with staggered flowering, and ground cover for slopes. Local species pair well with the large trees already in place, taking care not to damage their roots during the works.
Permits and neighbours
In Geneva, certain outdoor structures, such as a pool, a fixed pergola, a carport, a wall or major earthworks, may require a building permit issued by the canton. Felling a tree requires authorisation from the cantonal Office for Agriculture and Nature (OCAN). The landscaper checks with you what applies to your plot before work begins.
On a hillside, neighbours matter particularly: a wall, tall planting or a structure can change the view and the flow of water on neighbouring properties. A conversation beforehand avoids many disputes.

Frequently asked questions
Can a very steep plot be landscaped in Cologny?
Yes, it is a common situation on the hillside. The landscaper creates levels, retaining walls or gabions to gain flat areas and stabilise the ground. The site visit makes it possible to assess the slope, the soil and the flow of water before proposing a solution.
Does a pool with a lake view need a permit?
A pool may require a building permit from the canton, depending on its type and location. The landscaper checks with you what applies to your plot. They also take the terrain and the view into account when positioning the pool.
How can I shelter a garden from the bise without losing the view?
Structural planting, such as informal hedges or groups of shrubs, is combined with masses placed where they filter the wind without closing off views. A slatted timber or metal screen can complete the arrangement. It is all decided on site, according to the orientation of the plot.
Can large trees be kept during building work?
Most of the time this is possible and recommended in wooded parks. The landscaper adapts earthworks and site traffic to protect roots and trunks. If a tree has to be felled, authorisation from the cantonal Office for Agriculture and Nature (OCAN) is required.
What happens after I request a quote?
A qualified landscaper contacts you within 24 hours, then visits the site to understand your plot and your project. You then receive a detailed quote, free and with no obligation. The decision on what happens next is entirely yours.
