George Nakashima’s Art Building and Cloister, New Hope, PA 2015

The Arts Building and Cloister occupies a privileged position as the most iconic and architecturally significant of Japanese-American woodworker and architect George Nakashima’s built work. Dedicated on May 7, 1967, the building was intended as space of artistic interchange and contemplation. Of paramount importance is its hyperbolic paraboloid roof expressed in plywood.
Mancos Free Press, Mancos, CO 2015
Jackson Lake Lodge, Jackson, WY 2014

Completed in 1955, Jackson Lake Lodge was designed by architect Gilbert Stanley Underwood. The lodge is an example of the National Park Service’s interpretation of the International Style which became a hallmark of the Mission 66 Program from 1956 to 1966. The lodge combines elements of rustic structures of the earlier decades of the 20th century with a modern design aesthetic that responded to automobile travel.
Tumacácori National Historical Park, Tumacácori, AZ 2014

The Mission San José de Tumacácori is a Spanish Colonial mission now part of the Tumacácori National Historical Park. Federally designated in 1908, Tumacácori was one of the earliest national site dedicated to America's colonial Hispano history. The site is equally important for its long history of preservation and especially its surviving decorative painting on the exterior and interior.

Bar B C Ranch, Grand Tetons, Jackson, WY 2011

Established in 1912 by Struthers Burt and Horace Carncross, the Bar BC Dude Ranch is the oldest extant dude ranch in Wyoming and possibly in the United States. It is nestled on the flood plain between the Snake River and Teton Park Road. Created by its owners to include cabins, recreational buildings, a pool, corral, and fencing, the site was set up to offer paying customers the opportunity to socialize as well as enjoy the great outdoors.

Western Clay Kiln 7, Helana MT 2010

Brick and tile manufacturing was once ubiquitous throughout much of the United States. Today, however, only a fraction of these industrial complexes survive. Of those standing, few preserve the buildings and machinery, kiln technology, and overall industrial landscape as the Western Clay Manufacturing Company site on the outskirts of Helena, Montana.
Pipespring, Kaibab, AZ 2010

Housing lush springs in the arid Arizona Strip, Pipe Spring has historically been a valuable resource for the Kaibab Paiute Indians and later Mormon pioneers due to its history and location within the evolving Southwest landscape. Since 1923 the site has also served an important role in the National Park Service’s early interpretation of the scenic attractions and historical development of the region.

Farview House, Mesa Verde, Cortez, CO 2009
Gordion, Yassihoyuk, Turkey 2009

As one of the principal archaeological sites in Central Anatolia, Gordion premieres Phrygian architecture that includes a nearly complete monumental 9th century BCE masonry gate, along with the remains of a once impressive citadel. Few sites in the world offer a glimpse of the Late Bronze and Iron Ages in Anatolia.
Wagner Institute, Philadelphia, PA 2009
Whitney Studio, New York, NY 2009

As one of the few surviving examples of the work of artist Robert Winthrop Chanler, the Whitney Studio stands today as a masterpiece of early 20th century decorative art. Located on historic MacDougal Alley in Greenwich Village, the site is positioned at what once was the center of the early modern art movement in America.

Discovered in 1888, Spruce Tree House is one of the largest and best preserved alcove sites in Mesa Verde National Park. Containing over eighty rooms and seven kivas as well as open areas with very complete surface finishes with geometric embellishments, Spruce Tree House provides a remarkable window onto the region’s Ancestral Puebloan communities of the 13th century AD.

El Morro, Ramah, NM 2007
Merchants Exchange, Philadelphia, PA 2007

William Strickland’s Philadelphia Merchants’ Exchange Building in Independence National Historical Park is notable for its innovative architectural design including colossal order colonnades with fluted shafts of Pennsylvania marble surmounted by Italian Carrara marble capitals of the Composite order. Ornately carved and signed by their Italian craftsmen, the capitals represent some of the most exceptionally sculpted architectural elements in Philadelphia and the country.
Mt. Edgcumbe, Cornwall, England 2007
New York State Pavilion, Queens, NY 2007

Buildings, like people, pass through time. That passage, regardless of its duration, describes the lives of buildings. This project examines the relatively short life of an extraordinary building that played host to over six million visitors, the New York State Pavilion. Conceived, built and in use as designed for only two years, the Pavilion was witness to one of the most popular events of the 1960s, the New York World’s Fair.

The easily accessible Pennsylvania marble quarried just north of Philadelphia was an important regional building stone for public and domestic structures in the nation’s largest colonial city. During the first half of the nineteenth century, William Strickland’s Second Bank of the United States and Merchant’s Exchange were among the first monumental stone structures to showcase the area’s famous marble.

Vizcaya Miami, FL 2003

Vizcaya, built for industrialist James Deering, has survived remarkably intact since its completion in 1922, but unlike the house the gardens have undergone significant changes since their completion the following year. The periodic impact of tropical storms and hurricanes has created ongoing conservation concerns that continue to impact the plantings and the architecture of the gardens.
