The entry-level suite is a one-bedroom-plus-den at 646 square feet and $3.87 per square foot, while the peak listing is a two-bedroom at 848 square feet and $3.42 per square foot, meaning the higher rent buys substantially more living area at a lower unit rate.

Uptown Markham – Riverside Building B does not currently have a quantified den premium or square-footage delta isolable from active listings, as the paired sample is insufficient to calculate a reliable marginal cost per square foot for den space. Parking stall premiums likewise cannot be reliably isolated from current active listings, and no verified historical parking benchmark exists in the lease data to anchor a quoted figure.

Uptown Markham – Riverside Building B differentiates itself with a resort-style amenity suite that includes a hot tub and jacuzzi, sauna and steam room, outdoor pool, dedicated meeting room, and rooftop BBQ terrace—features that collectively outpace or distinguish it from each nearby competitor. Where Riverview B and Riverwalk East Building B both offer indoor pools, the subject provides an outdoor pool paired with a hot tub and jacuzzi, a combination none of the four comparables replicates. The sauna and steam room at Riverside Building B is matched only by Riverview B; Riverwalk East Building B and Ellington Park lack any spa facility. A dedicated meeting room is available at the subject but absent from both Riverside Building A and Riverview B, giving tenants a professional workspace without leaving the building.
