# Boulder on the Park (Tulsa, Oklahoma)

Boulder-on-the Park is the name of a three-story building at 1850 South Boulder Avenue in Tulsa, Oklahoma. Originally built in 1923, it represents Commercial Style Art Deco architecture, It was designed by the Atkinson & Olston architectural firm and built by C. A. Sanderson & Son. The building overlooks Veterans Park, south of Downtown Tulsa.

The building has served several different functions. Upon completion, it housed the Holland Hall School, and bore the name of the school until 1932, when the school moved to new and larger premises, the Boulder building housed corporate offices, particularly the Aero Exploration Company, an aerial mapping company, which occupied it from 1938 to 1946. The building was extensively remodeled in 1947, then occupied by radio station KTUL. The station coined the name "Boulder on the Park" for its new premises. It remained in the building until 1956, when it moved to new facilities on Lookout Mountain and converted to a television station, KTUL-TV. Holway Engineering Corporation bought the building in 1957 and remained there until 1974. The building was used as office space by several other companies until 2000, when Pan Western Energy Company sold it to Lanny McIntosh, owner of The McIntosh Group, an architectural firm.

## Addition to NRHP

Boulder on the Park was added to the National Register of Historic Places in September 2003, under Criteria A. Its NRIS number is 03000872.

Although the building has been extensively remodeled since its original construction, its nomination was accepted because of its historical significance as a radio broadcasting station. The Period of Significance is stated as 1947, when KTUL moved into the building, to 1953 (50 years prior to listing on the NRHP).

## Original construction

This building faces east, toward Veterans Park. It is three stories high, with a flat roof, brick walls and concrete foundation. Since the property has a significant uphill grade from front to rear, the first floor was excavated into the hillside and is mostly below grade. None of the first floor is visible from the rear. The only entry was a single metal paneled door with a single light. The windows are wood with brick rowlock sills.

According to one news report, the school building had an interior area of 8,200 square feet (760 $m^2)$ which contained at least nine classrooms, a shop, gymnasium and a laboratory.

## 1947 modifications

Before radio station KTUL moved its studio from the National Bank of Tulsa building (now known as the 320 South Boston Building), its management decided to modernize the appearance. A rear entry was added to the west wall. The brick walls were painted, which emphasized the difference between the more decorative facing brick used on the front (east) and the first quarter of the north and south sides, and the common brick that covered the remainder of the building. Some additional architectural details were added to the facade, which gave the building a more Streamline Moderne appearance.
