9, 33 & 47 Erb Street West Condos

About 9, 33 & 47 Erb Street West Condos Development

9, 33 & 47 Erb Street West Condos is a new condo pre-construction phase by Momentum Developments, located at 9 Erb Street West, Waterloo, ON. 9, 33 & 47 Erb Street West Condos offers a more vibrant urban neighbourhood while respecting the existing fabric. This project’s estimated completion date is unknown.

Quick Overview of 9, 33 & 47 Erb Street West

The project at 9, 33, and 47 Erb Street West is a proposed 39-storey condominium tower located in the heart of Uptown Waterloo, just steps from the ION LRT and the city’s main commercial corridor. The development is spearheaded by Atrium Waterloo Limited Partnership, operating under Momentum Developments, a developer with a track record of transformative urban projects across the Kitchener-Waterloo region.

This isn’t your typical mid-rise condo. The proposal calls for a slender tower atop a 7-8 storey podium, consolidating three municipal addresses into a single high-density residential building with ground floor commercial space. The application was submitted in the mid-2020s and is currently under municipal review.

The site spans 9, 33, and 47 Erb St W, currently occupied by an existing parking lot and low-rise commercial buildings—including a convenience store noted for strong sales. The proposal consolidates these parcels into a single tower footprint.

Before construction can begin, the developer requires changes to the City of Waterloo’s Official Plan and Zoning By-law. The project is actively moving through the municipal approvals process, with public consultation ongoing via EngageWR.

Location & Neighbourhood: Uptown Waterloo Context

The 9 33 47 Erb Street West site sits on the south side of Erb Street, positioned between Caroline Street South and King Street South. This puts it squarely in Uptown Waterloo’s urban core, within walking distance of Waterloo Public Square and the neighbourhood’s bustling restaurant and retail scene.

What’s Nearby

• Waterloo Public Square – Less than 5 minutes on foot
• ION LRT Stations – Waterloo Public Square and Willis Way stations within 200-400 metres
• Universities – University of Waterloo and Wilfrid Laurier University are a short transit ride away (combined enrollment exceeds 60,000 students)
• Employers – Sun Life Financial headquarters and other office towers in the immediate area
• Shops & Dining – Uptown’s King Street corridor offers cafés, restaurants, and boutique retail

The existing building footprint and surface lots currently on site represent an underutilization of prime urban land. This proposal intensifies the property in line with the city’s vision for Uptown as a transit-oriented, walkable urban centre.

Transportation Access

The location specifically appeals to residents who want to reduce car dependence. With 248 bicycle parking stalls proposed and LRT access steps away, this is a project designed for urban mobility.

Development Proposal: Height, Uses & Density

The application proposes a single, slender 39-storey tower rising from a 7-8 storey podium—creating one of the tallest high rises in Waterloo’s Uptown character area. This mixed-use development combines residential living with street-level commercial activation.

Current planning documents cap building height in this area at around 30 storeys. The proposed 39-storey tower—reaching 122.2 metres—exceeds this limit, requiring both an Official Plan Amendment and Zoning By-law Amendment before the city can issue building permits.

Building Design & Architecture

Edge Architects and Studio Canoo are the design team behind this project, working alongside Momentum Developments and Atrium Waterloo Limited Partnership. These firms bring experience from other high-rise projects across the Kitchener-Waterloo region.

Podium-and-Tower Form

The design follows a classic podium-tower typology. The 7-8 storey podium aligns with the existing streetscape context, creating a pedestrian-friendly experience at ground level.

Above this base, a slender 39-storey tower rises, designed to minimize shadow impacts on surrounding properties and maintain view corridors through Uptown.

Design highlights include:

• Stepped terraces on the podium roof for outdoor amenity space
• Glazing and modern materials create a contemporary aesthetic
• Active ground floor with commercial uses animating the Erb Street frontage
• Reduced tower floorplate to create a slender profile and minimize massing impacts

Design Summary

The building aims to support Uptown’s transformation into a denser, more vibrant urban neighbourhood while respecting the existing fabric.

Site Layout, Parking & Access

The development reconfigures the existing parking lot footprint, with the tower occupying part of the current surface area. The proposal maintains a small number of surface visitors and commercial spaces while concentrating most parking within a structured podium.

Parking Structure Details:

• 1 fully underground level
• 1 partially below-grade level
• 6 parking levels embedded within the podium
• Total: approximately 216 vehicle parking stalls
• Parking ratio: ~0.52 spaces per unit (reflecting progressive urban transit-oriented policies

Bicycle Corral:

• 248 Type A bicycle corral spaces
• Supports active transportation and reduces vehicle dependency

Access & Loading:

• Primary vehicle access anticipated from a driveway off Erb Street West or an adjacent lot connection
• Loading areas positioned to minimize conflicts with pedestrians and the nearby LRT corridor
• Driveway easement on adjacent lot included in zoning variance requests

The reduced parking ratio aligns with the site’s exceptional transit access and the city’s goals for sustainable mobility in Uptown. Interior finishes and exact floor plans remain subject to detailed design approvals, but buyers can expect contemporary condo standards typical for 2020s high-rise projects: open-concept layouts, large windows, in-suite laundry, and efficient kitchens.

Amenities & Resident Experience

The proposal includes approximately 933 m² of combined amenity space, split between indoor and outdoor areas atop the podium structure.

Indoor Amenity Space

Based on the application and typical Momentum Developments projects, likely indoor amenities include:

• Fitness room with cardio and weight equipment
• Occupant lounge and social spaces
• Co-working area with WiFi
• Party room for private events
• Possible guest suites for visiting friends and family

Note: Specific amenities are subject to final design approvals.

Outdoor Amenity Space

The podium rooftop is designed as an elevated outdoor oasis for occupants:

• Landscaped terraces with seating areas
• BBQ stations and dining zones
• Children’s play areas
• Green features and planting
• Basement Commercial

The commercial space at street level will contribute to an active streetscape and enhance daily convenience for occupants. Depending on future tenants, occupants might enjoy a café, small shops, or professional services steps from their lobby.

These amenities support the urban living experience that Uptown Waterloo occupants increasingly expect—spaces that encourage community, health, and convenience without leaving the building.
