Learn moreOld Ottawa South sits between the Rideau Canal and the Rideau River, south of the Glebe, with Carleton University nearby. Its streets are mostly detached and semi-detached homes from the 1910s to 1940s, with a short commercial stretch of Bank Street and Sunnyside Avenue.
Many families renovate rather than move here, so projects often focus on making older homes larger, brighter and more efficient.

Commercial units along Bank Street south of the canal are typically small storefronts, cafés and services in older buildings. Fit-ups often include washroom upgrades, layout changes, lighting and finishes, coordinated with apartments above.
Scope, schedule and budget conversations start with a short call.
Typical projects include rear additions, second-storey additions, kitchen and bathroom renovations, and basement work. Homes near the river can have higher water tables, so waterproofing and drainage are part of basement planning.
As a residential general contractor in Old Ottawa South, GCO reviews existing conditions and structure before agreeing a scope.
Old Ottawa South is within the City of Ottawa, which handles permits and zoning. Properties near the Rideau River may have conservation-authority considerations, and additions must meet mature-neighbourhood rules.
