Earlier penthouse sales offer a price benchmark
The asking price is below two earlier Book-Cadillac penthouse sales cited in other Detroit coverage. In December 2020, Cindy Pasky and Paul Huxley bought a 5,100-square-foot, three-story residence spanning floors 29 through 31 for an estimated $3.537 million, which Deadline Detroit described as the city’s priciest single-family home sale in more than a quarter-century. In 2017, a 2,500-square-foot bi-level penthouse on the 29th floor sold for $1.8 million, then a city condo record, according to DBusiness Magazine.
Penthouse 2902 is listed for $2,795,000. According to MLive, the residence at 1114 Washington Boulevard covers about 3,079 square feet on two levels and has two bedrooms, an office, one assigned parking space and a storage unit. The listing is represented by associate broker Nicholas Asplund of @properties Christie's International Real Estate and Lux Partners Global.
A major renovation shaped the residence
According to MLive, the owner spent about $800,000 on renovations and home systems, with much of the work completed over six months in 2017 and a guest-bathroom renovation following in 2018. The owner also finished an upper-level area that had been unfinished when the unit was purchased.
MLive reports that the kitchen and primary bathroom were rebuilt. The kitchen includes a waterfall island and appliances by Dacor and Sub-Zero; the primary bathroom has a freestanding tub and marble finishes. These are selected examples of the reported work, not a complete renovation inventory.
Market figures provide a broader comparison
The listing comes amid reported weakness in Detroit’s condo market. A 2025 analysis by Logical Property Management, citing Real Estate One data through June, put the city’s average condo sale price at $259,883, down 11% year over year, and the average price per square foot at $216, down 10%. The analysis also reported a 15% decline in sales of units priced above $400,000.
Downtown housing and the building’s history
Downtown Detroit had more than 6,500 residents in April 2026, and the Downtown Detroit Partnership set a target of 10,000 residents within five years. Separately, a City of Detroit housing-market study by HR&A Advisors found that citywide owner-occupied home values recovered more slowly than values in the Detroit MSA and continued to lag them in its 2010–2021 analysis. That citywide measure is not a direct comparison for a downtown condo. The Book-Cadillac reopened in October 2008 after a restoration that brought hotel rooms and condominiums into the historic building, according to project architect Kaczmar Architects.
