Why choose a composite terrace?
Installing a composite terrace means choosing a contemporary material that frees you from the maintenance constraints of natural wood while retaining its charm. Designed to withstand, it is particularly suited to the Swiss environment.
A hybrid, aesthetic, and high-performing material
Composite wood is made from recycled wood fibers and plastic resins. It perfectly mimics wood while offering great dimensional stability.
It withstands weather, UV rays, frost, and humidity without cracking, warping, or graying.
A maintenance-free solution
Unlike natural wood, composite does not require sanding, oiling, or treatment against insects or mold. A simple wash with water is enough to maintain its shine.
It is an ideal material for those seeking a durable terrace without the burden of regular maintenance.
An environmentally friendly choice
Composite boards are often made from recycled materials, thus limiting their ecological impact. Some ranges are 100% recyclable.
They represent a sustainable alternative to exotic woods or threatened species.
Steps of a composite terrace installation project
At Avenir Rénovations Switzerland, each project is structured to ensure a durable, aesthetic result that complies with local standards. Here are the main steps we follow.
What are the different ranges of composite boards?
Depending on the manufacturer and the technology used, composite boards have varying characteristics. We help you select the product that best suits your project and budget.
Solid boards are very robust, resistant to shocks and heavy loads. They are perfectly suited for high-traffic decks or areas exposed to extreme conditions.
Their density gives them excellent long-term stability.
Lighter and more economical, hollow boards are hollow inside. They are perfect for residential decks subjected to moderate use.
They require careful installation with finishing caps to prevent water or dirt accumulation.
These premium boards are covered with a thin protective layer that enhances their resistance to UV rays, stains, and scratches. They retain their color longer.
They are ideal for sun-exposed areas or for achieving a very high-end aesthetic finish.
How much do composite terrace installation works cost in Switzerland?
The cost of a composite terrace depends on the type of board, the installation system, the surface area, the supporting structure, the finishes, and the accessibility of the site. Here is a realistic estimate of prices in French-speaking Switzerland:
| Type of service | Price per m² (CHF) | Average total price (CHF) |
| Hollow composite terrace | 280 – 400 CHF/m² | 6'000 – 12'000 CHF |
| Solid or co-extruded composite terrace | 350 – 550 CHF/m² | 8'000 – 15'000 CHF |
| Raised or suspended composite terrace | 400 – 700 CHF/m² | 10'000 – 20'000 CHF |
| Pergola, railing, lighting, furniture | Package according to options | 2'000 – 12'000 CHF |
These prices include materials, labor, structure, potential connections, and finishes. Each project is subject to a detailed and transparent quote.
What are the advantages of a composite terrace in Switzerland?
Composite terraces perfectly adapt to the climatic demands of Switzerland. They combine durability, safety, and aesthetics, even in challenging contexts such as mountainous areas or lakesides.
Exceptional durability
Composite is not afraid of frequent rain, snow, or negative temperatures. It retains its shape, color, and strength throughout the seasons.
This resistance makes it a reliable choice for terraces at altitude or in regions with high thermal contrast.
Enhanced safety
Composite boards are slip-resistant, even when wet, and pose no risk of splinters. They are particularly suitable for families with children or elderly individuals.
They offer excellent stability underfoot, regardless of the weather.
A wide variety of finishes
Available in many shades and textures, composite boards can mimic different wood species or create modern effects. The aesthetic choice is vast.
This allows you to perfectly adapt your terrace to the style of your home and outdoor spaces.
Types of installation for a composite terrace
The installation of a composite terrace varies according to the terrain configuration, the nature of the support, and the type of boards chosen. Our teams advise you on the method best suited to your project.
Installation on adjustable pedestals
This method is ideal for leveling slopes and irregularities in the terrain. It also allows for good ventilation of the structure and effective water drainage.
It is recommended for rooftop terraces, sloped gardens, or installations without a concrete slab.
Installation on joists
When the ground is stable, the boards can be fixed to a structure of joists placed on a concrete slab or a gravel bed. This is a quick and durable method.
The joists can be made of treated wood or aluminum according to preferences.
Installation on suspended frames
For elevated or balcony terraces, a reinforced supporting structure is necessary. It ensures the safety and stability of the whole.
We create metal or reinforced wood structures adapted to Swiss architectural constraints.
What regulations govern the installation of composite terraces in Switzerland?
In Switzerland, the construction of a terrace is subject to strict urban planning rules, which differ by canton and municipality. It is essential to comply with these obligations to avoid any future disputes.
Building permit or simple declaration
A ground-level composite terrace may sometimes be exempt from a permit, especially if it does not exceed a certain area (often 30 m²) and is not covered. However, an elevated terrace or one attached to a building generally requires authorization.
We help you check local rules and compile the complete administrative file.
Respect for distances and easements
Minimum distances from property boundaries are imposed to preserve privacy, safety, and proper water drainage. These rules can vary between 50 cm and 2 meters depending on the zones.
We integrate these constraints from the design phase.
Compliance of the structure and safety
The structure of the terrace must comply with current standards, particularly regarding allowable loads, stability, guardrails, and accessibility. Outdoor electrical equipment (lighting, outlets) must meet Swiss standards (NIBT).
Our projects fully comply with technical and regulatory requirements.
FAQ – Composite terrace: answers to your questions
Is composite really more durable than wood?
Yes, composite is designed to last several decades without warping, rotting, or requiring specific maintenance. It is resistant to insect attacks and temperature variations.
Can a composite terrace be installed over an old surface?
Yes, provided the old support is stable, level, and draining. A structure of joists or pedestals allows for elevating the composite boards without dismantling the existing surface.
Is composite slippery when it rains?
Quality composite boards are slip-resistant and designed to provide good grip, even when wet. They are safer than some exotic woods or polished concrete.
Does composite get very hot in the sun?
Less than some materials like tiles or dark concrete. Some dark shades can become warm, but co-extruded boards with UV treatment remain more comfortable.
Can a composite terrace be dismantled and reused?
Yes, if it was installed on a removable structure. The boards can be dismantled and reinstalled at another site, which is an advantage in case of relocation.
