What Section23 Developments does

Section23 Developments Ltd. is a privately held, Calgary-based residential land developer and home builder founded by Robert Ollerenshaw, building on a family agricultural legacy dating to 1923. The company operates through four core divisions: Baywest Homes (a Calgary home builder established in 1985 specializing in move-up, estate, and custom homes across more than twenty communities including Rangeview, Mahogany, Harmony, Rockland Park, and CreekView); land development (current and future master-planned communities such as Rangeview, Mahogany District, Section24, Springwell, and Sinton Lands); property management (The Ezra luxury condominiums in Hillhurst and The Rutherford Building in historic Inglewood); and formerly, seniors' living via The Edward, a 90-suite luxury independent living residence operated from November 2020 until its November 2025 sale to Chartwell Retirement Residences. The portfolio spans over 4,000 homes and seniors' residences delivered cumulatively and has earned 125+ BILD Calgary Region Awards.

The company's core differentiator is its long-term, vertically integrated developer-operator model combining land acquisition, master-planned community design, and in-house home construction through Baywest Homes. Rangeview is positioned as Calgary's first Garden-to-Table Community, pioneering "Agricultural Urbanism" — the integration of community gardens, food production, and food celebration into neighbourhood design. Heritage plays a central role: the Ollerenshaw Historic Ranch Site, a 7-acre parcel in Mahogany, is preserved for agricultural history, education, and community gardens, and the family legacy is embedded in community storytelling across the portfolio. Subsidiaries and sub-brands include Baywest Homes, Nest (executive townhomes), The Ezra, The Rutherford, and Rangeview.

Section23 generates revenue primarily through one-time residential home sales (Baywest Homes), land development fees and parcel sales to homebuilder partners, and recurring property management and leasing income from owned residential (13 Ezra condominiums) and commercial (The Rutherford) assets. Go-to-market is direct-to-consumer via Baywest Homes show homes across Calgary, the Baywest website with online registration and a VIP promotion offering $1,000 savings, community sales centres, social media, and event-based engagement. Land development is pursued through direct municipal engagement with the City of Calgary, Rocky View County, and Airdrie planning authorities. Pricing for homes is not publicly disclosed. The company is privately held by the Ollerenshaw family with no external institutional investment and reports no publicly disclosed revenue figures.
