It was designed by Giorgio Massari, and the building was completed between 1748 and 1772. The latecomer among the palaces on the Grand Canal of Venice, Palazzo Grassi has an academic classical style that is in contrast to the surrounding Byzantine Romanesque and Baroque Venetian palazzi. It has a formal palace façade, constructed in white marble, and lacking the lower mercantile openings typical of many Venetian patrician palaces. The Grassi family sold the palazzo in 1840, with ownership that followed passing through many different individuals.
