Elveden Centre, Office building complex in downtown Calgary, Canada

The Elveden Centre is an office building complex in downtown Calgary consisting of three towers rising from a shared atrium. The main tower reaches 80 meters across 20 floors, with approximately 447,814 square feet of rentable space throughout the structure.

Construction took place between 1959 and 1964 during Calgary's rapid expansion following the discovery of oil at Leduc No. 1 in 1947. This period marked a transformative time for the city as energy resources fueled its growth.

The tower names come from the titles of Benjamin Guinness: Elveden House from Viscount Elveden, Iveagh House from the Earl of Iveagh, and Guinness House from the family itself. Elveden is also the name of the Guinness estate in Suffolk. The complex was commissioned by British Pacific Building, a Guinness-owned company with stakes in Calgary firms Duke Drilling Investment Company and Seabridge Investments.

The complex houses restaurants, cafes, shops, and banking services within its spaces, making it convenient for visitors and workers alike. Its proximity to three LRT stations provides easy public transit access from different parts of the city.

The design follows the International Style and was created by the architectural firm Rule Wynn and Rule. The complex received Category A designation from the Calgary Heritage Authority in 2005, marking it as historically valuable.
