award winners Beautiful buildings built with natural stone N atural stone has lost none of its fascination over the years. On the contrary, the consumption of natural stone is growing throughout the world and its use in commercial buildings in particular, has skyrocketed. The project was complex and consisted of two distinct sub-projects. The first was the complete renovation of the actual villa; the second was the new construction of additional buildings directly adjacent to and surrounding the museum. Technological advances in all areas of stone production from quarrying, fabricating, and installing, have dramatically reduced the cost of using stone and architects the world over are embracing these increased advantages to create dynamic, award-winning buildings that will stand the test of time. Added features include a parking complex, a new entrance, new galleries, a research library, café, bookstore, conservation facility and 450-seat auditorium and an amphitheatre. New windows, lighting and earthquake-proofing were also part of the scheme. Once such project is the newly renovated Getty Villa in Malibu, California, which took out the Marble Institute of America’s 2006 Pinnacle Award for the best commercial exterior presented at Coverings 2007 in Chicago in April. Conrad Ello, a senior associate with Machado and Silvetti, said that the stones used on the project were sourced from Italy, Spain, Turkey, China, Greece and the US and were specifically selected by the architects for their colour and ability to support the design intent of the villa itself. One look at the images of the villa – and a brief history of its construction and intensive reinvention – and it is easy to see why the project was the hands-down favourite among the judging panel. “The architects made several trips overseas to the quarries to select the exact blocks and oversee production of finished materials. All up, 35 containers of stone were brought in to complete the renovation,” he said. The Getty Villa was built by philanthropist John Paul Getty in 1974 to house his art collection. Included in the containers were nine 2 x 2 x 4 metre blocks of Amarillo Triana, a buttery-yellow marble from Macael, Spain. Constructed as a reproduction of the Villa dei Papiri, one of the most lavish houses in Herculaneum, destroyed in AD 79 by the eruption of Mt Vesuvius, the villa boasts some 44,000 different works dedicated to the study of the arts and cultures of ancient Greece, Rome, and Etruria. “The blocks were hand-selected in two separate trips to Spain and the honed stone used on stairs in the museum and the café. Three similar sized blocks of Turkish onyx, quarried south east of Istanbul and supplied by Teodor Marble, were also purchased and cut into thick, plank-like pieces then vein cut and honed for use as cornice for the entry pavilion and as column capitals on the café,” explained Conrad. After most of the collection was moved to the new Getty Center in 1997, the villa was closed for renovation. It reopened in January 2006. The US$275 million renovation was designed and coordinated by Bostonbased architecture and urban design firm Machado and Silvetti Associates, a 40-person team known for distinctive spaces and unique works of architecture in the US and abroad. Building was carried out by the Morely Construction Company, with stone installed by Carnevale & Lohr. 20 issue 12 www.discoveringstone.com.au Around 465 square metres of honed and acid-etched China Black Marble quarried in China, was used for the central plaza floor and wall cladding. Honed and cleaved blocks of noce travertine, quarried and supplied from Italy, were also used as wall cladding and on select flooring and stair applications (stair treads/risers are cubic stones).

The aggregates were finished similar to terrazzo. The walls were sandblasted for a rough finish, while the floors were ground, honed and acid-etched to provide dramatic contrast,” said Conrad. “Italian porphyry was also used on select floor, stair and wall applications. Honed Carrara Marble, quarried and supplied by Massa Industries in Carrara, Italy, was used in the detailed applications within the museum, as well as for the front porch entrance stairs and ramps,” he added. German engineering According to Germany’s Federal Statistics Office (FSO), the German production of natural stone increased distinctly in 2006 with a 10.9 per cent rise on 2005 figures. For the same time, local consumption of natural stone increased by 5.1 per cent over the previous year. Despite the strong competition from cheaper imports, mainly from Asia, these rising demands show a great appreciation of local stones among consumers – and just like other commodities, the stones are subject to fashion trends. FSO surveys indicate that while the production quantities of granites and sandstones have remained constant, the production of limestones has risen by 23.7 per cent. Single-coloured stones from beige to grey and black are especially in demand. The long-term trend is that the appreciation of natural stone among developers and architects will also continue to grow, particularly in special applications such as airports and railway stations, and building facades. In June, Berlin architects Kleihues and Kleihues became the recipients of the German Natural Stone Award 2007 presented during Stone+tec at the Exhibition Centre Nuremberg. The firm received the prestigious accolade for the refurbishment of the iconic Galeria Kaufhof department store located at Alexanderplatz (square) in Berlin. In the past 100 years Alexanderplatz has witnessed profound changes and the Kaufhof department store is no exception. Its origins trace back to the beginning of the 20th century. After sustaining partial damage during the Second World War and its demolition in the 1960s, the building was reconstructed in a 1970s style with a façade of moulded aluminium panels that saw it become a dominant feature of the square. In 2004, the building was once again flagged for refurbishment. The project called for the modification and extension of the existing building with a strong emphasis on making it represent the successful reconstruction of Berlin’s city centre. The new facade is a modern interpretation of the classic department store architecture, including grand entrances, a two-storey base and moulded, structured natural stone surfaces. Architect Josef Kleihues achieved an elegant overall design using an exterior base of Nero Impala granite and approximately 9000 square metres of light-coloured Bavarian Gauinger travertine to clad the classically-proportioned facades, which were mechanically fixed to an aluminium frame. Another 270 square metres of the travertine was used to clad the interior of the main entrance, with approximately 310 square metres of Jura limestone used on the escalator handrails and elevator portals. The careful, sculptured stonework is continued in the exactly designed details of the entrances and base of the building. There are also many smaller detailed points throughout the building that add to the casual elegance of the project and help to round off the theme of the building. A lavish atrium crowned with a glittering glass dome that bathes the interior with light, completes the makeover, which cost more than $160 million and was completed in May 2006. www.discoveringstone.com.au issue 12 21
