A Richard Meier–designed residence conceived as a livable art gallery has quietly entered the Dallas market for $23 million. Set within the Park Cities enclave, it was built to house an 800-work collection now pledged to the Dallas Museum of Art.

A 409 m² (4,402 sq ft) Art Deco apartment once home to Brigitte Bardot during her marriage to Gunter Sachs has been listed for sale. With ten reception rooms and a 52 m² (560 sq ft) winter garden, it offers the kind of scale and formality long associated with Paris’s 16th arrondissement.

At its center stands the Mill House, built around the 1775 grist mill “Defiance,” constructed by the Livingston family during the Revolutionary era. The water that once powered its machinery remains visible from within the residence, now forming a waterfall backdrop.

Commissioned in the late 1930s for Milan’s Necchi Campiglio family, this architect-designed villa sits within 11 hectares (27 acres) of private parkland above Lake Varese, with custom interiors by the architect, and a pool shaped in the lake’s outline.

Set in the foothills of the Serra de Tramuntana, this Mallorcan estate is configured as a compound and has been reported by Spanish media to have hosted Cristiano Ronaldo.
