Burlington-based Nordblom Co. will test the market for class A office space in Boston’s South End as it pursues construction of a 230,000-square-foot office development at 321 Harrison Ave.

An 8-story office building would be built atop an existing 3-story garage, according to a notification form filed with the Boston Redevelopment Authority. The project, a joint venture with Philadelphia-based Rubenstein Partners, would be built on a 2-acre site across the street from the Ink Block mixed-use development.

“Along with the Ink Block development and the soon to be constructed (560-unit) 345 Harrison, the project has great potential to change and revitalize this area, serving as a vital physical and economic link between Downtown, Chinatown and South End neighborhoods,” the developers wrote in their BRA submission.

Designed by SMMA of Cambridge, the office building would be built of insulated glass in a metal panel system with some curtain walls with floor-to-ceiling glazing. The building will have sweeping views of the Financial District and Back Bay and be designed with totally open floor plates with “exceptional” ceiling heights, said Og Hunnewell, a partner with Nordblom Co.

The ground floor would include cultural or gallery space at the corner of Herald Street and Harrison Avenue. Copley Wolff Design Group is the landscape architect. Open space is planned next to 1000 Washington St., an 11-story, 234,900-square-foot office building that shares the site and will be retained.

Nordblom estimates the project would create 1,500 permanent jobs.

Nordblom and Rubenstein acquired the property for $75 million in January. Deke Schultz, New England director for Rubenstein Partners, said at the time that office rents are expected to rise as the neighborhood fills up with residential projects such as Ink Block and the 378-unit Troy Boston at 275 Albany St.

With large blocks of office and lab space increasingly scarce in the Seaport and Cambridge, the South End is attracting interest as a new frontier for commercial development.

Boston-based Abbey Group is planning a large development at the Boston Flower Exchange property on Albany Street. On Thursday, executives said they hope to build offices for tech companies and housing on the 5.6-acre site.
