indekscen.pl editorial team · published 30 September 2026 · prices according to the 5 October 2026 index

According to price lists, a framed balcony enclosure in a block of flats usually costs 750 PLN/m² (typically 750 ‑ 970 PLN/m²) including installation, while a frameless glass enclosure costs around 1,500 PLN/m². A balcony with a front requiring around 8 m² of glass can be enclosed with a framed system for approximately PLN 6,000. Permission from the owners' association or housing cooperative is usually required before ordering.

Enclosing a balcony in a block of flats is one of the most common ways to create an extra summer “room” and provide protection from dust, rain and noise. Prices in quotes look similar because nearly every contractor gives a starting rate per square metre. Below, we compare framed and frameless systems using medians from price lists, calculate the cost of several typical balconies and explain which permissions are required in a block of flats.

How much does a balcony enclosure cost in a block of flats?

A framed balcony enclosure in a block of flats usually costs 750 ‑ 970 PLN/m² including installation, while the median from 4 price lists collected by indekscen.pl is 750 PLN/m². The price is per square metre of glazing, not balcony floor area. This matters because a balcony with a floor area of 4 m² may require 8 or 12 m² of glass, depending on whether you enclose only the front or the sides as well.

According to contractors, materials account for most of the enclosure cost, with labour making up a smaller share. This is why an installation discount makes little difference to the price, while the choice of system and glass makes a significant difference. The full list of quotations from price lists is available at balcony enclosure.

Framed or frameless balcony enclosure: which should you choose?

A frameless glass balcony enclosure costs around 1,500 PLN/m², while a framed enclosure costs 750 PLN/m², so the difference per square metre is substantial. The right choice depends on what you expect from your balcony:

Feature	Framed enclosure	Frameless enclosure
Cost per m² (median)	750 PLN/m²	1,500 PLN/m²
Appearance	visible aluminium or PVC profiles	glass panels only, an “invisible” enclosure
Opening	sliding panels	panels slide and fold to the side
Weather sealing	better, with seals on the frames	gaps between the panels
View	interrupted by frames	nearly unobstructed

A framed sliding enclosure is the cost-effective choice: it provides better weather sealing and costs less. A frameless system creates the effect of an “open” balcony, and all the panels can be folded to the side in summer, but it costs considerably more. Polycarbonate or PVC panels are sometimes the cheapest option, but the building manager is less likely to approve such a solution.

Wooden balcony enclosures in blocks of flats are found mainly in older buildings and houses. We do not have prices for wooden enclosures in the index, so we do not compare them with aluminium systems.

How much does a balcony enclosure cost: examples

At the median rate, a framed balcony enclosure requiring 8 m² of glazing costs around PLN 6,000, typically PLN 6,000 ‑ 7,800. Below are three typical balconies in blocks of flats, calculated using the framed-system rate:

Example	Glazing required	Cost at the median	Typical cost
Small balcony, front only	approx. 6 m²	PLN 4,500	PLN 4,500 ‑ 5,800
Typical balcony, floor-to-ceiling front	approx. 8 m²	PLN 6,000	PLN 6,000 ‑ 7,800
Corner balcony, front and side	approx. 12 m²	PLN 9,000	PLN 9,000 ‑ 12,000
Large loggia or balcony with two sides	approx. 15 m²	PLN 11,000	PLN 11,000 ‑ 15,000

For a frameless enclosure, these amounts increase roughly in line with the ratio between 1,500 PLN/m² and 750 PLN/m². To calculate the area, measure the width of the front and sides, then multiply it by the height from the floor (or balustrade) to the ceiling slab.

What is usually not included in the price:

1. Sheet-metal flashing at the ceiling slab and floor, unless explicitly included in the quote.
2. Repairs to the balcony slab. An enclosure cannot be installed on crumbling concrete; according to price lists, balcony renovation costs around 1,250 PLN/m².
3. Fly screens for sliding panels; installing a balcony fly screen costs around PLN 600.
4. Roller blinds or Venetian blinds providing protection from the sun.

Can a balcony in a block of flats be enclosed?

A balcony in a block of flats can be enclosed, but before paying a contractor you will usually need permission from the building manager, either the owners’ association or the housing cooperative. The balcony forms part of the facade, and the facade is a common part of the building, so the building manager decides how it may look. Many owners’ associations already have a resolution setting out an approved enclosure design, including the profile colour, system and type of glass. In that case, choosing a contractor is simply a matter of finding a quote that conforms to the design.

Ask the building administration:

• whether there is a resolution on balcony enclosures and which design it permits,
• whether the building is in a heritage conservation area,
• whether the building manager requires a design or structural engineer’s opinion,
• who is liable for damage if the installation damages the facade or insulation.

Is planning permission required for a balcony enclosure?

A balcony enclosure in a block of flats does not usually require planning permission, but depending on the scope of the work and the authority’s interpretation, it may require notification to the county office. A listed building may also require permission from the conservation officer. Rules on changes to facades are applied differently in different cities, so ask the architecture department of your county or city office before ordering an enclosure costing PLN 6,000 or more.

Can you enclose a balcony without permission from the owners’ association?

Enclosing a balcony without permission from the owners’ association or housing cooperative exposes the owner to a demand to remove it at their own expense and, in some cases, to a court dispute. In practice, this means risking the entire amount spent on the enclosure, typically around PLN 6,000 ‑ 7,800 for a standard balcony. Obtaining permission from the building manager usually costs only time, so it is worth getting it in writing before signing a contract with a contractor. If there is a dispute, consult a lawyer.

Can you install a balcony enclosure yourself?

Simple systems from DIY stores can be installed yourself, but on the upper floors of a block of flats, installing heavy glass panels on the outside of the building requires experience and fall protection. Contractors measure the balcony, order a made-to-measure system and take responsibility for weather sealing. Labour accounts for a smaller share of the price, so the saving from self-installation is less than it might seem, while you bear the risk of damaging the glass or facade.

What should you ask a balcony enclosure contractor?

• Does the price per m² include installation, finishing work and waste removal, or only the system itself?
• What type of glass is included in the quote: toughened or laminated, and how thick is it?
• Which system are the profiles from, and will I receive the documentation required by the owners’ association?
• How is water drained from the bottom track?
• What warranty is provided for the system, glass and installation?
