The owner of a high-visibility property in North Bethesda is proposing a mixed-use development that would combine two senior housing complexes with a roughly 200-foot office tower.

An initial proposal submitted earlier this month to the Montgomery County Planning Department by Guardian Realty LLC indicates the three new buildings would be arranged around an existing office building at 6000 Executive Blvd. The company owns the roughly 7-acre property and has its corporate offices in the seven-story building that currently stands on the site, just southwest of Pike & Rose.

The first phase of the project would be to construct a six-level building with 131 residential units for people aged 62 and older. The housing would sit above four levels of underground parking and would be on the south side of the existing office building.

The second phase would involve building a larger active adult complex, which could be up to 150 feet tall and have 233 units, according to the plan. An urban plaza would be wedged between the building’s north side and Executive Boulevard, and above-ground and underground parking would serve the community.

The final building would be an office and retail tower of up to 200 feet, standing at the intersection of Old Georgetown Road and Executive Boulevard. The plan calls for a neighborhood green of about a half-acre near Old Georgetown Road, possibly including seating areas and public art or a pavilion. Sidewalks and paths would connect an urban plaza at the tower’s northeast side with the entrance and the neighborhood green.

Guardian explained in its proposal that it would design that office tower as a “heroic building,” of an architectural quality that lives up to its prominent location. The design could employ “glass and a dynamic interplay of shapes” and use façade setbacks and folds to create outdoor spaces.

The development plan would retain the 1970s-era office complex that stands at the center of Guardian’s site.

Planning staff will review Guardian’s sketch plan application before presenting it to the Montgomery County Planning Board.
