How much does a French balcony cost?
Having a French balcony installed costs on average between €3,500 and €4,000 for a standard version three metres wide. These costs include the railing or glass pane, the swinging doors, and the installation. The total price depends on the type of balustrade, the dimensions, and the type of doors you choose.
French balcony cost components
| Cost item | Price |
|---|---|
| Railing | €200 to €400 per linear metre |
| Swinging doors | €500 to €2,500 per piece |
| Labour and installation costs | €60 to €70 per hour |
The largest cost item is the railing, especially if you choose glass or high-quality metal. Swinging doors vary greatly in price: standard internal doors are cheaper than luxury garden doors with double glazing.
French balcony project costs
| Type of project | Price |
|---|---|
| Small French balcony (cheap railing, inward-opening door) | €1,500 |
| French balcony 3 metres wide (finished railing or glass) | €3,500 to €4,000 |
| Full glass wall with luxury doors and railing | €7,800 to €9,100 |
The cheapest variant is a small French balcony with a simple inward-opening door. For a luxury version with a full glass wall and high-quality swinging doors, you will pay significantly more. The price also increases if you want a wider balcony or have specific requirements for finish and design. The stated prices include 21% VAT and labour. These are indicative prices based on previously completed jobs by affiliated professionals.
Costs of French balcony by type and material
The costs for a French balcony vary greatly by material type and execution. A plastic railing is the cheapest but has a shorter lifespan, while wrought iron is more expensive but offers a classic look. For glass balustrades, there are choices between clear glass, frosted glass, and laminated safety glass, with safety glass being mandatory according to building regulations. The swinging doors also make a big difference: simple inward-opening doors are the cheapest option, while folding walls or accordion doors are more flexible but cost more.

| Glass balustrade | Clear or frosted glass | €300 to €400 per linear metre |
| Glass balustrade | Laminated safety glass | €400 to €500 per linear metre |
| Swinging doors | Simple internal door | €500 to €1,000 per piece |
| Swinging doors | Luxury garden doors with double glazing | €1,500 to €2,500 per piece |
| Swinging doors | Folding wall or accordion door | €2,000 to €3,500 per piece |
Price-determining factors for a French balcony
The costs for a French balcony vary per project because every balcony is unique. The construction of one facade differs from another, and your wishes and the local situation also play a role. Below you can read which factors influence the price and why.
Complexity of the construction
The condition of your walls, the type of facade, and existing window frames determine how much work is required. Cavity walls require different mounting methods than solid walls. Sometimes extra reinforcements or special anchors are required to securely anchor the railing. The more complex the construction, the more time the professional needs and the higher the labour costs.
Load-bearing capacity of the facade
Not every facade can support the weight of a French balcony. A structural inspection may be necessary to determine if the wall is strong enough. If reinforcements turn out to be necessary, costs will rise due to extra material and labour.
Required materials
Plastic railing costs around €200 per linear metre, while wrought iron or stainless steel costs between €300 and €400 per metre. Safety glass is more expensive than standard glass but often mandatory according to building regulations. Material costs determine a large part of the total costs.
Dimensions of the balcony
The larger the French balcony, the more material and labour are required. A balcony 1.5 metres wide is cheaper than a balcony 3 metres wide. The price increases linearly with width because you need more railing, longer doors, and more mounting materials.
Insulation requirements for frames and doors
Frames and doors with good insulation values (low U-value) are more expensive to purchase but save on energy costs in the long term. Poor insulation leads to heat loss and condensation problems. Investing in high-quality doors increases initial costs but pays for itself.
Safety regulations
According to the Building Decree, the balustrade must be at least 100 to 110 centimetres high, and the bar spacing may be a maximum of 11 centimetres. Safety glass is often mandatory. If the professional has to make extra adjustments to meet these requirements, it will cost more time and material.
Permits and permission
Depending on your municipality, an environmental permit may be required. For monumental buildings or protected cityscapes, additional rules apply. In VVE apartments, permission from the VVE is required. Applying for permits takes time and sometimes money, which influences the total price.
Region and local prices
In large cities, prices are often higher than in rural areas. This is due to higher labour costs and higher demand for professionals. Choosing a local professional sometimes saves on travel costs and time.
Condition of the facade
Small defects such as moisture problems or cracks in the facade must be resolved first. If these are discovered during installation, the professional must perform extra repairs. This costs more time and material. Good preparation prevents these extra costs.
Urgency and planning
Urgent jobs are more expensive than planned work because the professional has to adjust their schedule. Work at weekends also costs more due to surcharges. Plan your project in time to avoid these extra costs.
Accessibility of the workplace
Ensure the workplace is clear and accessible. Think about access to the facade, any scaffolding, and protection of furniture inside. If the professional has to spend extra time clearing the workplace or arranging scaffolding, labour costs will rise.

Extra costs depend on the specific situation. At Zoofy, you pay no call-out charges.
- Urgency surcharge: A surcharge often applies to urgent jobs because the professional has to adjust their schedule
- Weekend surcharge: Work at the weekend is more expensive than during the week
- Additional work for facade defects: Defects in the existing facade must first be repaired before the balcony can be installed
- Reinforcements: Necessary reinforcements of the load-bearing structure increase costs
- Adjustments: Extra costs can arise from adjustments to electricity or sun protection
- Scaffolding: For high-situated balconies, extra costs for scaffolding or aerial platforms sometimes apply
How does the professional work when installing a French balcony?
Installing a French balcony proceeds in a fixed sequence of five steps.
- Assessment and advice: The professional inspects the facade and assesses the load-bearing capacity of the wall. Desired railing types, glass, and doors are discussed. Any permit requirements are also checked.
- Preparation: The existing window or frame is removed and the wall opening is adjusted where necessary. For cavity walls, the professional places special mounting anchors.
- Installation of frame and doors: The new frame is placed level and square. The inward-opening doors or folding doors are mounted and adjusted for optimal operation.
- Installation of balustrade: The railing or glass pane is securely attached to the facade. The professional checks the mounting points for load capacity and ensures the height complies with the Building Decree.
- Finishing: All seams are sealed for watertightness and insulation. The interior is neatly finished. The consultation and ordering takes about one week, production of custom materials two to six weeks depending on the material, and installation takes one to three days. Costs are clear in advance so you know what to expect.
How can you save on a French balcony?
There are several ways to reduce the costs for a French balcony without compromising on quality.
- Have the facade inspected in advance: Small repairs to moisture problems or cracks are cheaper than additional work during installation. An inspection prevents surprises and high extra costs.
- Ensure the workplace is clear: Remove furniture near the window yourself and ensure access to the facade. This saves labour hours and lowers total costs.
- Plan during the week: Do not book at the weekend or as an urgent job. Plan the task well in advance to avoid weekend and urgency surcharges.
- Choose a smaller size: A balcony 1.5 or 2 metres wide is significantly cheaper than 3 metres, while maintaining the same effect.
- Choose affordable material: Plastic frames and simple railings are cheaper than wrought iron or stainless steel and often fit your living style perfectly.
- Book through Zoofy: You get a fixed rate in advance, with no call-out charges and no surprises. You only pay after completion of the job.
Common problems when installing a French balcony?
Problems during installation can have various causes.
Insufficient load-bearing capacity of the wall
In older homes or cavity walls, the load-bearing capacity is sometimes insufficient to support the weight of the railing and doors. This leads to dangerous situations where the construction can sag. A structural inspection in advance prevents these problems and determines if reinforcements are needed, which affects the costs.
Moisture problems in the facade
Existing moisture damage or cracks in the facade must be repaired first. Ignoring them leads to leakage after installation, allowing water to penetrate and causing mould growth. This causes health problems and damages the construction.
Poor insulation
Cheap frames with low insulation values cause heat loss and higher energy costs. Condensation on the inside leads to moisture damage to walls and frames, which requires extra repairs over time.

Costs vary because plastic railing is cheaper than wrought iron or stainless steel, and the choice of swinging doors or folding walls also influences the price.
Do I need a permit for a French balcony?
This varies by municipality. A French balcony is a facade change, which often requires an environmental permit or notification. For monumental buildings or protected cityscapes, additional rules apply. Always consult your municipality's environmental counter.
What are the requirements for a French balcony?
According to the Building Decree, the balustrade must be at least 100 to 110 centimetres high, and the bar spacing may be a maximum of 11 centimetres. Safety glass is often mandatory. These requirements prevent fall hazards and ensure the balcony meets safety standards.
What is the purpose of a French balcony?
A French balcony provides more natural light and a spatial effect in your home. It has no walking surface but does have a balustrade or glass pane, allowing you to safely enjoy the view with inward-opening doors open. It increases quality of life without a costly extension.
Is my wall strong enough for a French balcony?
This depends on the construction. Solid walls are usually suitable; for cavity walls, special anchors may be needed. A professional can assess the load-bearing capacity during an inspection. If capacity is insufficient, reinforcements are necessary, which increases costs.
How long does the installation of a French balcony take?
The actual installation takes 1 to 3 days, depending on the complexity. Add to that the production time for custom materials: 2 to 6 weeks for custom frames and doors.
Can I have a French balcony installed in a rental property?
You need permission from the landlord for this. For an apartment, approval from the VVE (owners' association) is also required. You may not make facade changes without permission.
What is the lifespan of a French balcony?
This depends on the material. Plastic lasts 20 to 30 years, aluminium and stainless steel 30 to 50 years, and well-maintained wrought iron even longer. Regular maintenance extends the lifespan.
Is a French balcony safe during a storm?
Yes, provided it is correctly installed according to building regulations. Safety glass and sturdy fixings are resistant to normal weather conditions. The professional anchors the railing securely into the facade.
Is a French balcony suitable for a child's room?
Yes, provided the balustrade meets safety standards: at least 100 to 110 centimetres high and bar spacing of maximum 11 centimetres. Glass balustrades prevent small hands or toys from passing through.
