A Tudor mansion on Sheridan Road in Winnetka sold Friday, June 26, for $7.8 million, nearly six times the $1,314,000 median single-family sale price in New Trier Township last year.
The six-bedroom home was designed by Mayo & Mayo, according to the Chicago Tribune, which first reported the sale. Buyer and seller names have not been publicly disclosed. The Tribune's Bob Goldsborough covers North Shore luxury transactions.
Mayo & Mayo designed dozens of mansions, clubs and hotels across the North Shore and Chicago. British-born architect Ernest Mayo arrived in Chicago as an adviser for the 1893 World's Columbian Exposition and built a residential practice that shaped the lakefront corridor through the early 20th century.
The sale comes as Cook County's latest reassessment cycle shows a 39% jump in total assessed value for New Trier Township, certified by Assessor Fritz Kaegi in April 2025 and reflecting three years of market gains. Those values will affect second-installment tax bills issued in 2026. New Trier Township includes Winnetka, Wilmette, Glencoe, Kenilworth and portions of Glenview and Northfield.
At $7.8 million, the Sheridan Road transaction sits at the upper tier of a market where the assessor's median market value estimate for single-family homes is $1,186,000. It follows another high-end Winnetka deal: attorney Patrick A. Salvi II listed a six-bedroom home in the Hubbard Woods neighborhood for $2.4 million in May 2026, eight years after paying $1.88 million for it. Salvi's newer Winnetka home, purchased in late 2023 for $4 million, carried an $80,344 property tax bill in the 2024 tax year.
The specific street address, square footage and listing price for the Sheridan Road property were not available from published sources as of Friday, June 26.
