The Grudge (Al Ba’sa): Beirut’s razor-thin house built out of spite

Some buildings are designed to inspire. Others are built to solve practical problems. And then there is Al Ba’sa, better known as The Grudge—a remarkably narrow building in Beirut that exists largely because two brothers simply could not get along.

Completed in 1954, this peculiar structure has become one of Lebanon’s most unusual architectural landmarks. At its widest point, the building measures just over 4 metres, while its narrowest section shrinks to barely 60 centimetres. Seen from certain angles, it appears less like a house than a freestanding wall squeezed between neighboring properties.
Yet despite its astonishingly slim proportions, Al Ba’sa was designed as a fully functional residential building. Each floor originally contained two apartments, making it one of the most extraordinary examples of how architecture can be shaped not by necessity or beauty, but by human conflict!

Its origins lie in an inheritance dispute.
After their father’s death, two brothers inherited a parcel of land in Beirut.
Dividing the property, however, proved anything but simple.
Over the years, municipal infrastructure projects had carved away sections of the original estate, leaving behind an awkward, wedge-shaped plot that seemed almost impossible to develop.
Rather than abandoning the oddly shaped parcel, one brother saw an opportunity—not to maximize its value, but to settle a personal score: as a result, he built a house that followed the exact contours of the narrow plot.
The unusual design had an unintended architectural distinction but a very deliberate purpose: it blocked his brother’s panoramic view of the Mediterranean Sea. The obstruction not only deprived him of the scenery but also diminished the appeal—and potentially the value—of the neighboring property.
It was an extraordinary act of revenge, immortalized in reinforced concrete.

Although it looks impossibly thin from the street, Al Ba’sa was never intended to be merely symbolic, as people actually lived there.
Each level was divided into two apartments, proving that even the most unconventional footprint could be adapted into usable living space. Over the decades, the building witnessed very different chapters of Beirut’s history. One apartment reportedly operated as a brothel for several years, while others later provided shelter for a family displaced by war, giving the structure a role far removed from the bitterness that had inspired its construction.
Either way, like much of Beirut itself, the building gradually accumulated layers of history that extended well beyond its unusual origin.

More than seventy years after its construction, The Grudge remains standing in one of Beirut’s most valuable neighborhoods.
Ironically, modern zoning regulations have become the building’s greatest protection, as the plot beneath it is now considered too small for new development.
Should the structure ever be demolished, current planning laws would prevent another building from replacing it, making the land less valuable without the house than with it.
Its survival is therefore due not only to history but also to legislation.

Architect Sandra Rishani aptly captured this paradox when she observed that Al Ba’sa “continues to exist grudgingly and also defiantly in one of Beirut’s most prime locations; only time will tell what will become of it.”
And today, The Grudge stands as more than an architectural curiosity, but It is a rare physical reminder that cities are shaped not only by planners and engineers, but also by deeply personal stories. Behind its paper-thin façade lies a tale of inheritance, rivalry, revenge, survival, and the unexpected ways in which human emotions can leave a permanent mark on the urban landscape.
