You’ve probably already come across these windows lined with bars that beautifully curve outward. A charming detail, certainly… but which actually hides a clever trick, at once practical, reassuring and very decorative. What if these metal « bellies » completely changed the game in your layout? You’ll see, they’re not just there for show…
Grilles like no other: the detail that changes everything

At first glance, these rounded grilles simply add relief to the facades, like a vintage touch that we love in old neighborhoods. But their curvature is not an aesthetic coincidence. Historically, these curved shapes were designed to protect homes while leaving a little space… And this space, it seems , has more than one trick up its sleeve!
A perfect support for your floral desires
Who hasn’t dreamed of a little patch of greenery, even in the city center? Thanks to this famous curve, the rounded grids easily accommodate well-stocked planters. Geraniums, aromatic herbs, or even small urban vegetable gardens : everything has its place, hanging from the window, without eating into the interior space. A real plus when you live in an apartment and want to breathe a little nature into your daily life!
Imagine: a street lined with flower-filled windows , a sweet scent wafting from the plants, and the warm feeling of a living facade… All made possible by this small, well-thought-out architectural detail.
And in terms of comfort, they also deliver!

But that’s not all. In many older homes, especially in hot areas, air conditioners are installed directly on window sills . And guess what? Curved grilles allow them to be securely mounted without sacrificing protection. The unit is kept secure while benefiting from better ventilation, thanks to the free space. A truly practical and effective trick, one that we don’t always think about.
