Sluneční věž, Modern residential tower in Karlín, Prague, Czech Republic.

Sluneční věž is a modern residential tower in Karlín featuring 21 floors that rise to about 70 meters. A glass exterior wrapped with aluminum sunshade systems protects the interior from sun exposure while allowing natural light inside.

Sluneční věž was built between 2008 and 2011 by the contractor UNISTAV, rising in Karlín near the Olympik hotel. Its 21 floors were planned to hold 30 apartments, but unsold units led some floors to be used as offices. Interior architect Bořek Šípek described the design as avant-garde postmodernism.

The building design follows avant-garde postmodern principles, creating a distinctive silhouette in Prague's architectural landscape alongside structures like the Dancing House.

The tower stands near the Olympik hotel in Karlín; its glass facade with aluminium sunshades is best seen from the surrounding streets. Some floors hold offices rather than flats, so the interior is not open to visitors. The building is a short walk from the Invalidovna metro station.

The interior was designed by Bořek Šípek, who called the style avant-garde postmodernism. The all-glass facade is screened by aluminium sunshades, a detail that links the tower visually to the Dancing House nearby.
