174 Stanley Avenue - Archive Square
From city archives to riverfront lofts
174 Stanley Avenue — known as Archive Square — is one of Ottawa's most intimate and coveted loft addresses, situated directly on the banks of the Rideau River in the heritage enclave of New Edinburgh. Built in 1936 as a school and later repurposed as the City of Ottawa Archives, the red-brick building with its iconic stone entrance was masterfully converted by Warlyn Construction in 1999 into just 11 high-end loft suites across three storeys. Soaring 11–12 foot ceilings, full walls of east-facing heritage windows, gleaming maple hardwood floors, gas fireplaces, open-concept layouts, spacious west-facing balconies with natural gas connections, and in-unit laundry make Archive Square one of the finest boutique loft buildings in the city — all steps from Stanley Park, the Minto Bridges, and the Rideau River.
From classrooms to archives to riverfront living
A building that has held the city's memories — first educating its children, then storing its history, and now housing the people who continue to write it.
