Renovate a house It is usually an exhausting experience: budgets that skyrocket, structural unforeseen events, provisional solutions that end up being permanent. Now imagine that this home is not just any apartment, but one of the great icons of the 20th century, visited by millions of people and examined to the millimeter by historians, engineers and conservators. Then the reform stops being a domestic problem and becomes a continuous battle against time. Thus an icon was born. The assignment that changed a career The year was 1934 when Edgar J. Kaufmann commissioned Frank Lloyd Wright a weekend house next to a waterfall in Bear RunPennsylvania. The architect then took an unprecedented decision: He decided not to look at the water from afar, but to literally build on it. The work, built between 1936 and 1938, almost immediately became in a manifesto of organic architecture: concrete terraces that float over the waterfall, local stone walls that sprout from the rock, spaces that open to the forest as if the house were an extension of the landscape. By January 1938 he already occupied the same cover of time and critics proclaimed it one of the great masterpieces in the history of architecture, one capable of reconcile modernity and nature in an unforgettable image. It happens that there is always a “but” in a work, and one like this was no different. Yes. That perfect image had a disproportionate price from day one. The original cost exceeded the planned budget almost four times and reached approximately $155,000 of the time, a figure equivalent to about 3.3/3.5 million current dollars. Added to this were Wright’s own fees and the expenses derived from a complex execution in a unique but remote environment, so that the project was born already financially stressed. What should be a weekend country house became a total commitment, technical and economic, to materialize a radical vision. And we come to the material that has given the work its name, although it almost took everything away. The gesture that made Fallingwater world famous, its large columnless cantilevers over the waterfall, was also its Achilles heel. During the work, the engineer in charge of concrete warned that only eight reinforcing bars had been placed on a main beam and that, for a span of that length, it should have been duplicated steel. However, Wright rejection the objections, arguing that adding more reinforcement would damage the structure and demanding absolute confidence in their judgment. The contractor, without warning, decided to increase the steel anyway. Even so, when removing the formwork the first cantilever deformed more than four centimeters and was left with a permanent arrow that today translates into a visible slope close to two degrees. And the cracks came before inhabiting it The problems were neither theoretical nor late. Even before the Kaufmann family moved in in 1937, there were already documented leaks and cracks on the concrete parapets. As the decades passed, some balconies began to sink. more than 20 centimeters with respect to its original position, and in the nineties engineers found that the cantilevers they had failed technically and required urgent reinforcements to avoid greater risk. The house that seemed to defy gravity rested on a more fragile balance than the iconic photograph suggested. If the waterfall was the soul of the project, the rain and snow were its nightmare. Flat roofs, terraces that function as roofs for lower rooms and masonry walls holes filled with rubble They made it easier for water to find invisible paths into the interior. So much so that since the 1940s the house was nicknamed with irony by its owners for the number of buckets needed to collect leaks, and almost ninety years later an intervention of 7 million dollars intended to seal covers, inject more than a dozen tons of grout on the walls and improve waterproofing. It didn’t matter the crazy price that had been used previously, many leaks they returned with time. The overhang of the living room seen from the bridge leading to the house At the end of the 20th century and the beginning of the 21st, a structural restoration was undertaken that would be decisive: the beams were drilled and introduced steel cables post-tensioned to “pull” the concrete and recover part of its original position. That operation prevented the sinking will progressbut it did not eliminate the need for ongoing maintenance. To give us an idea, from 1937 to today, the preservation of Fallingwater has already exceeded 19 million dollars, a figure multiplied by about 120 times the initial cost of construction and which illustrates the extent to which keeping the icon standing has been more expensive than its own creation. In 1963 the Kaufmann family donated the house to the Western Pennsylvania Conservancy, which opened it to the public the following year. Since then, more than 6 million of people have visited it, and its status as a National Historical Monument and UNESCO World Heritage Site consolidated his status as one of the masterpieces of the 20th century. Paradoxically, the same audacity that generated the cracks, deformations and leaks is what gave it its symbolic force: Fallingwater, or The Falling House, embodies the rhetoric of the American dream of merging with nature and dominating it at the same time, even when that ambition required paying an enormous structural and economic price. The history of this icon shows that architectural genius is not exempt material risk. Wright’s possibly exaggerated authorship, his conviction towards engineers and contractors, and his willingness to take concrete further of prudent limitsproduced a work that was both sublime and problematic. If you will, it is also an imperfect building that has needed decades of disagreements, revisions and reinforcements to remain standing. And precisely for that reason, more than a frozen postcard over a waterfall, Fallingwater It is proof that great works are born from the tension between vision and reality, and that even masterpieces can always be, literally, at the edge of the … Read more
