Balcony, terrace, window sill: what are the differences and uses?

Not all apartment outdoor spaces are equal, and they cannot be furnished in the same way. Here's how to distinguish between a balcony, a terrace, and a windowsill.

In everyday language, we often use "balcony" and "terrace" interchangeably, but these two spaces operate on very different principles. Adding the windowsill, a third type of apartment outdoor space, helps in choosing how to furnish each one better.

This vocabulary confusion isn't just a matter of semantics: it often leads to furnishing errors when solutions designed for a terrace are applied to a balcony, or vice versa.

The Balcony, an Elevated Extension

A balcony is a platform projecting from the facade, usually surrounded by a railing and accessible only from a single room. Its surface area is limited, often narrow, sometimes reduced to just a few tens of centimeters deep.

Its entire organization relies on intelligently utilizing this railing, which becomes the real furnishing resource rather than the floor, contrary to what one would instinctively do for a more generous outdoor space. It is this depth constraint that fundamentally distinguishes a balcony from other types of outdoor spaces.

The Terrace, a True Extension of the Ground

Unlike a balcony, a terrace rests at the same level as an interior room or on a roof, with a generally more generous surface area, sometimes large enough to accommodate several distinct zones.

It allows for furnishing closer to that of a garden, with furniture placed on the ground and more freedom of movement. This additional surface also allows for uses that a balcony could not accommodate, such as a real dining area or a separate relaxation space.

This is also the space where a brand like Bibelo makes perfect sense. Their powder-coated aluminum chairs, benches, and tables, with more refined lines and a sleek design, can complement any terrace with color and quality.

The Windowsill, the Smallest but Not the Least Useful

Often overlooked, the windowsill is nevertheless the only outdoor space available in many Parisian homes without a balcony or terrace, especially in small apartments or on high floors without direct outdoor access.


A few centimeters of depth are enough to install a compact planter and some herbs, a minimal but real solution to maintain a connection with the outdoors. This format, though modest, often allows enough aromatic plants to be grown for regular use in the kitchen.

What Furniture for Which Space

On a terrace, classic floor-standing furniture works well; the space largely allows for it, and stability is generally not an issue. On a balcony, however, furniture that utilizes the railing rather than the floor is preferable.

This is precisely the principle of Balconie and Balconnières from Extra Terrasse, designed to attach directly to the railing without anything on the ground, regardless of the balcony's narrowness. On a windowsill, only a compact planter truly fits, without it being possible to install larger furniture.

In Summary

Balconies, terraces, and windowsills are not alike and cannot be furnished in the same way. Precisely identifying your type of outdoor space is the first step to choosing truly suitable furniture.
