European country style achieved with Texas limestone veneer
May 19, 2009
The homeowners of a private residence in Austin, TX, sought a space that exhibited French/English country influences. And to achieve this desired style, they incorporated regional Texas limestone into the home’s design.
“The house picks up on a very rural sensibility found in French/English farmhouses,” said Project Architect David Webber of Webber + Studio, Inc. in Austin, TX. “The front door is almost incidentally located, and the largest most entry-like fronts are large archways that indicate the use being more important than the incidental entry a few steps down the facade.”
The architect went on to explain that in old farmhouses, large doors were used to move livestock in and out of the structures. “They were the most prominent aspect [of a farmhouse],” he said. “Whereas, the farmer’s living quarters were often smaller and more modest - almost incidental to the work of running the farm. The same is true with this home. The main windows and doors reflect the largest and most important rooms, such as the living room and the master [bedroom], but the circulation routes along the back of the house are treated less importantly.”
While the home itself measures approximately 7,500 square feet, an additional 3,500 square feet consists of one attached garage and a three-car garage that is connected to the house by a covered porte-cochere breezeway. According to Webber, his clients required that the residence also contain a living room, a dining room, a kitchen with a breakfast area, a master bedroom with a master bath that included “his” and “hers” water closets and closets, a study/library, two children’s bedrooms - each with a suite bath and closet, a children’s television/play area, two full guest suites and associated sitting area, a laundry/dog kennel room, a pool bath and a powder room.
“Stone is prominent throughout the design,” said the architect. “The house is large, but we did not want it to feel that way. It also sits on a ridge along the top of a small bluff - offering great views into a valley and natural area. In order to spread the size of the house out, we broke it into two zones - the main house and the kids/guest part of the house.”
Webber explained that by dividing the residence into two zones, it presented the opportunity to differentiate between the two main volumes by utilizing two different stone applications on the exterior. “For the main house, a fairly soft, local, white, chalky, fossilized limestone with cut shellstone quoins was used, while the other [part of the home features] a more slurried application using multi-colored limestones at various levels of weathered appearance, which were locally available,” he said. “Locally, we can get from very white chalky limestone to rusty, brown, tan and even blackish limestones, depending on how much aging they have been exposed to in their creation.”
The mason on the project, Richard Llewellyn, located the stone for the home in a range of stoneyards and supply shops in the Austin region. The homeowners were also very involved in the selection process.
“They had a great awareness for how they wanted it to feel, and the mason was able to do mock-ups to test out their reaction to the possibilities,” said Webber. “But, before we even got to that point, the clients would drive around for weeks before they finally located a stone that they liked and felt comfortable was the right selection.”
In the end, the chosen limestone varieties proved ideal for creating the French/English-style farmhouse. “The chalky limestone and its softness seemed informal enough for the overall look,” said the architect. “By using it with some ledges inserted into [the stone], and with a cut stone version for the quoins, we achieved both informality with a hint to formality that informal architecture often tries to achieve in spite of itself.”
Webber added that the slurried stone part of the house needed to have an even more informal quality than the main house. “The stone we picked there - with its multi-colors and its very informal application - would do the trick. Slurried walls were often done as a substrate for stucco. The stone was not intended to be finished.”
While the extensive stonework used for the exterior appears thick, it actually is all veneer stone that has a thickness of only 4 inches. The pieces ranged from 6 inches in dimension to some pieces that measured 24 x 20 inches and some even larger.
According to the architect, not much direct supervision was needed during the stone installation. “We certainly were involved with selecting the stone, but the mason was so talented that, in fact, the stone we did select was generated in the form of a mock-up by him matching a few stone walls that we had seen while driving around,” said Webber. “Because the mason was the one that generated those samples, we really did not need to direct him at all.”
