The Kaufmanns and Wright were enjoying refreshments at La Tourelle when Wright, who never missed an opportunity to charm a potential client, said to Edgar Jr. in tones that the elder Kaufmanns were intended to overhear, “Edgar, this house is not worthy of your parents...” The remark spurred the Kaufmanns' interest in something worthier. Fallingwater would become the end result.

The Kaufmanns owned property outside Pittsburgh with a waterfall and cabins they used as a rural retreat. When the cabins deteriorated, Mr. Kaufmann contacted Wright.

Design and construction


The structural design for Fallingwater was undertaken by Wright in association with staff engineers Mendel Glickman and William Wesley Peters, who had been responsible for the columns featured in Wright’s revolutionary design for the Johnson Wax Headquarters

.

Preliminary plans were issued to Kaufmann for approval on October 15, 1935, after which Wright made a further visit to the site and provided a cost estimate for the job. In December 1935 an old rock quarry was reopened to the west of the site to provide the stones needed for the house’s walls. Wright only made periodic visits during construction, instead assigning his apprentice Robert Mosher

 as his permanent on-site representative. The final working drawings were issued by Wright in March 1936 with work beginning on the bridge and main house in April 1936.


The construction was plagued by conflicts between Wright, Kaufmann, and the construction contractor. Uncomfortable with what he perceived as Wright's insufficient experience using reinforced concrete

 design reviewed by a firm of consulting engineers. Upon receiving their report, Wright took offense and immediately requested Kaufmann to return his drawings and indicated he was withdrawing from the project. Kaufmann relented to Wright's gambit and the engineer’s report was subsequently buried within a stone wall of the house.

After a visit to the site in June 1936, Wright rejected the stone masonry for the bridge, which had to be rebuilt.

For the cantilevered floors, Wright and his team used upside down T-shaped beams integrated into a monolithic concrete slab which both formed the ceiling of the space below and provided resistance against compression. The contractor, Walter Hall, also an engineer, produced independent computations and argued for increasing the reinforcing steel

 in the first floor’s slab. Wright refused the suggestion. While some sources state that it was the contractor who quietly doubled the amount of reinforcement, according to others, it was at Kaufmann’s request that his consulting engineers redrew Wright’s reinforcing drawings and doubled the amount of steel specified by Wright. In addition, the contractor did not build in a slight upward incline in the formwork

 of the cantilever. Once the concrete formwork was removed, the cantilever developed a noticeable sag. Upon learning of the steel addition without his approval, Wright recalled Mosher.

With Kaufmann’s approval, the consulting engineers arranged for the contractor to install a supporting wall under the main supporting beam for the west terrace. When Wright discovered it on a site visit he had Mosher discreetly remove the top course of stones. When Kaufmann later confessed to what had been done, Wright showed him what Mosher had done and pointed out that the cantilever had held up for the past month under test loads without the wall’s support.

In October 1937, the main house was completed.

Cost


The home and guest house cost US$155,000, broken down as follows: house $75,000; finishing and furnishing $22,000; guest house, garage and servants' quarters $50,000; architect's fee $8,000.

The total project price of $155,000, adjusted for inflation, is the equivalent of approximately $2.4 million in 2009. A more accurate reflection of the relative cost of the project in its time is that the cost of restoration alone in 2002 was reported at $11.4 million.

Use of the house


Fallingwater was the family's weekend home from 1937 to 1963. In 1963, Kaufmann, Jr. donated the property to the Western Pennsylvania Conservancy

. In 1964, it was opened to the public as a museum. Nearly six million people have visited the house as of January 2008. Despite its location in a remote corner of Pennsylvania (two hours' drive from Pittsburgh), the house (according to the informational pamphlet distributed on the grounds) currently hosts more than 150,000 visitors each year.

Style



Fallingwater stands as one of Wright's greatest masterpieces both for its dynamism and for its integration with the striking natural surroundings. Wright's passion for Japanese architecture

 in the living room integrates boulders found on the site and upon which the house was built — ledge rock which protrudes up to a foot through the living room floor was left in place to demonstrably link the outside with the inside. Wright had initially intended that the ledge be cut flush with the floor, but this had been one of the Kaufmann family's favorite sunning spots, so Mr. Kaufmann suggested that it be left as it was. The stone floors are waxed, while the hearth is left plain, giving the impression of dry rocks protruding from a stream.

Integration with the setting extends even to small details. For example, where glass meets stone walls there is no metal frame; rather, the glass and its horizontal dividers were run into a caulked recess in the stonework so that the stone walls appear uninterrupted by glazing. From the cantilevered living room, a stairway leads directly down to the stream below, and in a connecting space which connects the main house with the guest and servant level, a natural spring

 drips water inside, which is then channeled back out. Bedrooms are small, some with low ceilings to encourage people outward toward the open social areas, decks, and outdoors.


Bear Run and the sound of its water permeate the house, especially during the spring when the snow is melting, and locally quarried stone walls and cantilevered terraces resembling the nearby rock formations are meant to be in harmony. The design incorporates broad expanses of windows and balconies which reach out into their surroundings. The staircase leading down from the living room to the stream (mentioned above) is accessed via movable horizontal glass panes. In conformance with Wright's views, the main entry door is away from the falls.

On the hillside above the main house stands a three-bay carport, servants' quarters, and a guest house. These attached outbuildings were built two years later using the same quality of materials and attention to detail as the main house. The guest quarters feature a spring-fed swimming pool which overflows to the river below. After Fallingwater was deeded to the public, the carport was enclosed at the direction of Kaufmann, Jr., to be used by museum visitors to view a presentation at the end of their guided tours on the Western Pennsylvania Conservancy (to which the home was entrusted). Kaufmann, Jr. designed its interior himself, to specifications found in other Fallingwater interiors by Wright.

Repair work



The Western Pennsylvania Conservancy conducted an intensive program to preserve and restore Fallingwater. From 1988, a New York City-based architecture and engineering firm was responsible for the materials conservation of Fallingwater. During this time the firm reviewed original construction documents and subsequent repair reports; evaluated conditions and probes; analyzed select materials; designed the re-roofing and re-waterproofing of roofs and terraces; specified the restoration for original steel casement windows and doors; reconstructed failed concrete reconstructions; restored the masonry; analyzed interior paint finishes; specified interior paint removal methods and re-painting; designed repair methods for concrete and stucco; and developed a new coating system for the concrete.

 of the concrete cantilevers was noticed as soon as formwork was removed at the construction stage. This deflection continued to increase over time, and eventually reached 7 inches (over a 15-foot span).

In 1995, the Western Pennsylvania Conservancy commissioned a study of Fallingwater’s structural integrity. Structural engineers analyzed the movement of the cantilevers over time and conducted radar studies of the cantilevers to locate and quantify the reinforcement. These showed that the contractor had indeed added reinforcement over Wright's plan; nevertheless, the cantilevers were still insufficiently reinforced. In fact, both the concrete and its steel reinforcement were shockingly close to their failure limits. As a result, in 1997, temporary girders were installed beneath the cantilevers to carry their weight.

In 2002, the structure was repaired permanently using post-tensioning. Blocks were joined to the concrete cantilever beams and floor joists, high-strength steel cables were fed through the blocks and exterior concrete walls, and then the cables were tightened using jacks. The floors and walls were then restored, leaving Fallingwater’s interior and exterior appearance unchanged. The cantilevers now had sufficient support, and the deflection stopped.
