Historical Research & Preservation Planning in Arizona

Most historic preservation projects start with a study of one type or another.  We have broad experience in the study of existing buildings and historic districts,  the application of the Secretary of the Interior's Standards, and the exacting identification and documentation requirements of the National Park Service.

Our ability to manage all aspects of the historic preservation world sets us apart from other architects. Project types include:

  • Historic Resource Surveys 

  • National Register Nominations

  • Preservation Master Plans

  • Building Analysis Reports

  • HABS/HAER Documentation

David & Gladys Wright House Building Assessment 

Phoenix, AZ​


This home, designed by Frank Lloyd Wright for his son and daughter-in-law, was threatened with demolition. Motley Design Group conducted a building assessment report with cost estimates in order to help to market the property to someone who would save it.  As a result the building was saved and is being restored.

Fort Defiance Indian Hospital HABS Documentation 

Navajo Nation​


The Navajo Area office of the Indian Health Service commissioned this documentation to satisfy NHPA Section 106 requirements for mitigation prior to demolition. The documentation included over 100 archival 4x5 format photographs and written narratives covering four related buildings. 

Route 66 in Arizona Historic Survey 



The Arizona State Historic Preservation Office (SHPO) received a grant from the National Park Service’s Route 66 Corridor Preservation Program in 2010 to fund a comprehensive survey of potential Route 66 resources in Arizona, from the California state line to the New Mexico state line. A total of 889 properties were inventoried. Documentation of each property included a determination of eligibility to the National Register and a prioritization for preservation. 

Stout's Hotel Building Assessment

Gila Bend, AZ​


Stout’s Hotel, also known as the “Jewel of the Desert,” was acquired by the Town of Gila Bend in an effort to preserve it. It had remained in the hands of the Stout family since it was constructed in 1929. The hotel was designed by noted Southwestern architects Trost & Trost and served as the main stopping place between Phoenix and southern California from 1929 until Gila Bend was bypassed by Interstate Highway 8 in the late 1970s. Motley Design Group was hired to provide a feasibility study including building assessment, rehabilitation plan, and cost estimates.

Lowell Observatory CAP Assessment

Flagstaff, AZ​


This project encompassed an architectural Conservation Assessment of all of the historic buildings atop Mars Hill in Flagstaff, comprising the campus of the world renowned Lowell Observatory.  Lowell has recognized their facility as a historic resource in addition to being a working astronomical observatory.  The assessment will guide future work on the campus to help preserve its historic qualities.
