A 4-square-metre balcony isn't a compromise — it's a creative constraint. The wrong awnings turn it into a dark tunnel. The right ones double the usable space, making it feel like a true outdoor room. Here are the five models that work under 6 m², with real 2026 prices and the dimensions that actually matter.
The 5 models to consider
Drop (vertical) awning
Rolls down from above and hangs vertically. Folded depth: 12–15 cm below the railing. Ideal against low afternoon sun and for privacy. Price range: €80–300. The downside: only effective when sun comes from the side, not directly overhead.
Cassette awning with extending arms
The Italian classic. Opens horizontally with spring-loaded arms. Widths from 1.5 to 4 m, projection 1.5–3 m. Folded depth: 18–25 cm. Price range: €200–1,500. Best coverage against high sun. Requires a load-bearing wall for mounting.
Vertical roller shade (privacy screen)
Micro-perforated fabric on a side-mounted roller — pulls across like a blind. Folded size: 7–10 cm cassette on one side. Price range: €150–500. Works as a visual divider between adjacent balconies.
Custom sail shade
Fabric stretched between 3–4 anchor points. Triangular, rhomboid, or trapezoidal shapes. Folded size: rolls down to 5×40 cm for storage. Price range: €60–250 for standard sizes. The most stylish option, but wind above 40 km/h and it acts like a sail.
Wall-mounted cantilever parasol
A middle-ground solution. Fixed to the wall with an adjustable arm, covers a circular area. Folded footprint: 10×100 cm against the wall. Price range: €80–300. Great for small balconies under 3 m² where structural installation isn't an option.
Which model for which orientation
East-facing balcony
Low morning sun. Use a drop awning or vertical roller shade. Minimal footprint needed since coverage is only required for 3–4 hours.
South-facing balcony
Overhead sun all day. Choose a cassette awning with at least 2 metres of projection. Below that, you'll still be in full sun at noon even with the awning open.
West-facing balcony
Intense low afternoon sun. A drop awning is the best solution here — better than a parasol. If building rules prevent wall fixings, use a side-mounted roller shade instead.
North-facing balcony
Sun only in June–July at peak hours. A cantilever parasol or removable sail shade is enough. Save your money.
Building regulations to check BEFORE you buy
Mandatory colour
Many buildings have resolutions specifying a single awning colour. Historic centres almost always require cream or dark brown. Ask your building manager before purchasing.
Maximum projection from the façade
Often limited to 1.2 m by building rules. A cassette awning with 2.5 m projection would be non-compliant — even if it physically fits.
Wall drilling
On protected façades (historic centres, listed buildings) you may need a SCIA permit or municipal approval.
Distance from neighbours
Civil code: 75 cm from the boundary if the awning is extendable. A sail stretched to an adjacent balcony is almost always illegal.
Frequently asked questions
Can I install a cassette awning on my own?
For models under 2 m wide, yes — provided you have a hammer drill and the right wall anchors (look for 30 kg rated chemical anchors). Over 2 m, always use a professional installer: a wall pull-out is catastrophic.
How much fabric do I need to cover 4 m²?
A 2.5×2 m cassette awning covers about 5 m² with a good pitch. For narrower balconies (1.5 m wide), two drop awnings on different sides will serve you better than one large cassette awning.
Are motorised awnings worth the extra cost?
Only if you'd use them more than 100 times a year (i.e. every day for 3–4 months). Below that frequency, manual crank models are more reliable and last twice as long.
What happens if it rains while the awning is open?
Modern fabrics resist light rain but collect water: the weight can distort the arms. Above 5 mm/h rainfall: close it. Automatic wind+rain sensors cost €80–150 extra but prevent damage when you're not home.
Drop awning or sail shade: which makes the balcony feel smaller first?
The sail shade. It creates a visual 'ceiling' that makes the space feel lower. A drop awning, being lateral, leaves the sky open above and makes the balcony feel larger.
