A 141-unit apartment complex would rise in Watertown Square under preliminary plans submitted by a New York developer.

O’Connor Capital Partners is proposing the redevelopment of five parcels spanning 1.4 acres and bounded by Main, Cross and Pleasant streets. The project consists of the construction of a five-story complex including podium parking, ground-level retail and apartments on the upper floors.

A 10-unit residential building at 2-5 Cross St. would be converted into amenity space, while the Gardner building at 104-106 Main St. will be restored or replicated for ground-floor retail space, according to a preliminary filing submitted to the Watertown Planning Board.

Developers will take advantage of the site’s sloping grade to partially obscure the two-story parking garage, located between Main and Pleasant streets.

Designs by ICON Architecture of Boston reflect the variety of site conditions and would create the appearance of a collection of buildings, developers stated in a filing. The facade facing Main Street would include brick cladding on the western section and a deep setback on the fifth floor for outdoor residential decks.
