Hôtel Max Hallet, Art Nouveau townhouse on Avenue Louise, Brussels, Belgium.

The Hôtel Max Hallet is a four-level townhouse at 346 Avenue Louise, built by Victor Horta in Euville stone. Its wide, symmetrical facade has three bays: a ground floor with a carved wooden door and segmental-arched windows, a first floor with three tall windows behind a continuous wrought-iron balcony, and three stone dormers under a slate mansard roof. The only asymmetry is the door bay.

Victor Horta built this town house between 1903 and 1906 for his friend Max Hallet, a lawyer and politician. The symmetrical Euville stone facade marked a turn toward a more restrained, classical manner in Horta's career. It has been a protected monument since 16 October 1975 and was restored around 2001 and 2007.

The house was built for Max Hallet, a lawyer and politician and a friend of Victor Horta, not an industrialist. Its wide, symmetrical Euville stone facade marks Horta's shift to a more restrained, classical manner after his earlier Art Nouveau designs. The carved dormer frames show floral Art Nouveau ornament.

Located at 346 Avenue Louise, the residence can be reached via multiple public transport lines and stands within walking distance of Hotel Solvay, another Horta design that offers further insight into his architectural style.

Inside, a marble staircase with bronze railings connects various levels through geometrically arranged spaces, demonstrating Horta's concept of continuous spatial flow that distinguished his residential work from conventional layouts.
