Statement of Significance

Description of Historic Place
Magrath Mansion is a two and one half-storey building situated on a large city lot overlooking the North Saskatchewan River in Edmonton's Highlands neighbourhood. Built between 1912 and 1913, the red-brick mansion is an eclectic construction with a stately design strongly influenced by the Georgian Revival and Neoclassical architectural styles. Prominent features of the Magrath Mansion include the symmetrical front facade, two-storey colonnade supported by robust classical columns, hipped roof with gable dormers, and wraparound porch and balcony.

Heritage Value
The heritage value of the Magrath Mansion lies in its association with Edmonton's pre-World War One building boom and its excellent representation of the Georgian Revival architectural style.

In the years between the creation of the Province of Alberta in 1905 and the outbreak of World War One in 1914, Edmonton experienced dramatic growth. The development of the city's transportation infrastructure and the growth of the regional economy swelled Edmonton's population and stimulated the foundation of over 270 new subdivisions. Among the most significant figures in the city's pre-World War One building boom were Bidwell Holgate and William J. Magrath, two eastern Canadians lured west by the tantalizing prospects of the Prairies. This entrepreneurial pair established a real estate company in 1909 and was involved in numerous projects to create residential areas for Edmonton's growing population. Their most ambitious undertaking was the creation, development, and promotion of the Highlands, a subdivision located on the north side of the North Saskatchewan River. Envisioned as an exclusive preserve of Edmonton's burgeoning entrepreneurial and professional class, the Highlands was graced with such genteel luxuries as minimum building standards, street cars, concrete sidewalks, street lighting, and sewer and water mains. To impart the Highlands with an air of elegant grandeur and thereby entice well-heeled Edmontonians to take up residence in the neighbourhood, both Magrath and Holgate built stately mansions in the area. Built between 1912 and 1913, the residence expresses in its lavishness and scale the ebullient optimism of the pre-war period in Edmonton. But it is also emblematic of the vagaries of Alberta's cyclical economy: by the early 1930s, the Magrath family had fallen behind in the payment of property taxes and the home was seized by the local sheriff.

Occupying a huge tract of land overlooking the North Saskatchewan River, Magrath Mansion boasts an imposing exterior and 14 ornately appointed rooms. Designed by Ernest W. Morehouse - the architect also responsible for the Holgate Mansion - Magrath's residence is an eclectic construction evincing the strong influences of the Georgian Revival and Neoclassical architectural styles. The Georgian Revival style is evident in the hipped roof with gable dormers, full-facade porch, sidelights and transoms surrounding doors and windows, and use of quoins, modillions, and dentillated eaves. The impressive two-storey colonnade with robust classical columns crowned by Ionic capitals is a bold expression of the Neoclassical architectural vision. The spacious grounds, panoramic vision of the North Saskatchewan River, and sophisticated design of the Magrath Mansion visually projected the economic clout and social prominence of its owner. The interior was equally ostentatious, graced by a variety of exotic materials - including mahogany, Italian marble, hand-painted silk and linen wallpaper, and Bohemian crystal - as well as ornate furnishings and details like the French chandelier in the reception area, the winding oak staircase to the second floor, the fireplace faced with hammered brass in the library, and the intricately painted, sculptured plaster ceiling in the dining room. At the time of its construction, the Magrath Mansion was also fitted with a range of luxurious modern conveniences, including an indoor pool in the basement, an electrical switch in the den that controlled all the lights in the home, an elaborate intercom system, a telephone connection in every room, an in-wall vacuum system and a burglar alarm. The extravagant interior of the Magrath Mansion is an excellent example of the lavish design aesthetic of upper class Edmontonians during this period.

Real estate dealer W.J. Magrath built this mansion in 1912 to reflect his success in Edmonton's pre-World War One building boom. It is one of the finest architectural achievements in Alberta, with fine materials and craftsmanship used in the interior and exterior of the home. Oak paneling, a grand winding staircase, linen wall coverings, sculptured ceilings and built-in leaded-glass cabinets on the main floor are among the many interesting architectural features.

W.J. Magrath resided here until his death in 1920. Magrath, a successful businessman actively involved in real estate, was involved in the development of the Highland subdivision in Edmonton. The house remained in the Magrath family until the early thirties. Few homes built during Edmonton's development excel the Magrath Mansion in architectural design, craftsmanship and materials.
