CRYSTAL BALL REPORT January 2024

581 to 595 Langs Drive

One of the oldest affordable housing properties in Waterloo region will be rebuilt from the ground up starting this spring now that Cambridge city council has granted final approval to official plan and zoning bylaw amendments for 581 to 595 Langs Dr.

The new housing project, seven storeys of mixed housing units with a youth community centre on the ground floor, will replace 38 units with 136 apartments of various sizes at an estimated 2021 cost of $46 million.

Another one third of the units will be low end of the market rent and the final one third of the units will be below average market rent.

The proposed multi-storey development will provide unit types that range from one to five bedrooms “to offer a diverse range of housing choices to future residents.”

The project will include a large outdoor amenity space behind the building that will feature a playground area, coloured asphalt play areas, a gazebo-like structure, as well as barbecue pits and picnic benches for larger gatherings with additional landscaping around the site.

Indoor amenity areas are also proposed including a multi-purpose room, meeting room and community gathering space.

It will include 135 parking spaces and three drop-off spaces within a surface parking lot. Of those, 96 spaces are allocated to residential units at a calculated rate of 0.70 spaces per unit.

A total of 34 spaces are provided as visitor parking spaces and are calculated at a rate of 0.25 spaces per unit in accordance with the city’s zoning bylaw.

Five additional parking spaces will be dedicated to the Youth Community Centre and six will be barrier-free parking spaces for the entire site.

The site will also provide for a total of 60 bicycle parking spaces, where 48 will be located within the building and 12 will be outside.

Demolition of the existing, 52-year-old townhomes is expected to begin in spring 2023 with the new units ready for occupancy around December 2025.
