Highlights of Stone Abbey

Stone Abbey is a boutique luxury residential development by Windmill Development Group situated in Ottawa’s highly coveted Old Ottawa South neighbourhood. The project beautifully blends heritage preservation with contemporary design by integrating the historic Southminster United Church into the fabric of the development, creating a unique architectural presence that stands out along the iconic Rideau Canal. This fusion of traditional stone and modern elements creates residences that feel timeless yet current, appealing to discerning buyers who value thoughtful design and a sense of place.

Comprising a limited collection of approximately 19 luxury condominium residences and a small number of executive townhomes, Stone Abbey emphasizes exclusivity and quality over scale. Units vary in size and layout, designed with high-end finishes, large windows for abundant natural light, and elevated outdoor spaces that maximize views and connection to the surrounding environment.

Beyond its architectural merits, Stone Abbey stands out for its location and lifestyle appeal. Just steps from Lansdowne Park, boutique shopping on Bank Street, waterfront pathways, parks and a host of cultural and dining options, the project offers an urban experience rooted in walkability and local character. Its close proximity to central Ottawa’s amenities makes it a compelling choice for both homeowners seeking a refined urban lifestyle and investors targeting high-end residential real estate.

Location and Neighbourhood

Stone Abbey is located at 15 Aylmer Avenue in Old Ottawa South, one of Ottawa’s most established and desirable neighbourhoods characterized by mature tree-lined streets, historic homes, and a strong community feel. This prestigious address overlooks the scenic Rideau Canal, a UNESCO World Heritage Site, and sits just south of Lansdowne Park, known for its vibrant public events, markets, sports teams, and cultural programming.

The neighbourhood’s appeal lies in its seamless blend of urban convenience and natural beauty. Residents can stroll along waterfront paths, enjoy cafes and independent shops along Bank Street, access top-rated restaurants, and attend seasonal festivals and farmers markets without needing a car. The area’s proximity to parks such as Brewer Park and Dow’s Lake further enhances outdoor lifestyle options, from cycling and kayaking in summer to skating on the canal in winter.

Old Ottawa South also benefits from excellent connectivity to the rest of the city, with frequent transit routes and easy access to downtown Ottawa. This accessibility, combined with the neighbourhood’s established infrastructure — including schools, recreational facilities, and cultural venues — makes it a genuinely walkable and vibrant community that attracts families, professionals, and empty-nesters alike.

Reason to Invest In Stone Abbey 

Investing in Stone Abbey is compelling for several reasons, beginning with its prime Old Ottawa South location. Properties in this area consistently command strong demand due to the neighbourhood’s mix of heritage charm, proximity to urban amenities, and lifestyle attributes that appeal to a wide range of buyers. The scenic Rideau Canal and access to pedestrian pathways and parks further enhance long-term appeal and resale value.

The development’s boutique scale and limited inventory are also attractive to investors. With only a small number of luxury units available, scarcity supports strong market dynamics, especially in a segment where exclusivity adds value. Coupled with high-end finishes and design curated by respected architects and interior designers, Stone Abbey positions itself above average condo developments, appealing to premium buyers and affluent renters alike.

Finally, the integration of heritage architecture and modern construction sets Stone Abbey apart. This thoughtful design and community integration — including the partnership with Southminster United Church — demonstrates a depth of planning and attention to detail that tends to appeal to end-users rather than purely speculative investors. Properties that attract lifestyle buyers often experience steadier demand and more resilient pricing over time, making Stone Abbey a solid consideration for long-term residential investment.

A Closer Look at the Ottawa Real Estate Market

The Ottawa real estate market has historically been more stable than many other Canadian urban centres, supported by a strong public sector, steady population growth, and diversified economic drivers in technology, government, education and health care. Demand for centrally located condominium residences has remained robust, particularly in established neighbourhoods with walkable access to amenities and transit.

While market conditions can fluctuate with broader interest rate and economic trends, areas like Old Ottawa South continue to outperform due to limited supply and high buyer interest in boutique, high-quality developments. Such neighbourhoods often retain value even in softer markets because they offer lifestyle attributes that are difficult to replicate in newer suburban developments — including heritage context, mature streetscapes, and immediate access to cultural and recreational assets.

Urban infill developments that respect existing community character and enhance neighbourhood vibrancy also attract interest from a range of buyers, from local downsizers and young professionals to international investors seeking exposure to Canada’s residential real estate. As Ottawa’s city core continues to evolve with thoughtful infill projects like Stone Abbey, opportunities for distinctive, value-oriented investments in premium locations remain strong.
