Local developer Claridge is asking the city for permission to build three 28-storey mixed-use towers at 245 Rideau Street, according to documents issued by the city.
The proposed development would have approximately 43,932 square metres of floor space, a note recently circulated to members of the local community said.
The site, which is currently home to a grocery store, is bordered by Cumberland Street to the west and George Street to the north.
The three towers would share a single podium, which would range from three to seven storeys.
The plan calls for 578 residential units, along with commercial space at ground level. The development would have 658 parking spaces, located on six levels of underground parking.
The company paid $22.15 million for the property, according to data published earlier this year. Claridge is one of Ottawa’s largest downtown condo developers.
