Ibler Building, Modernist residential building in Donji grad, Croatia.

The Ibler Building, known locally as the "Wooden Skyscraper", is a complex in Donji grad made up of a two-storey commercial block and an eight-storey residential tower, ten floors in all. Drago Ibler designed it and it was built from 1956 to 1958. Shops occupy the ground floor, offices fill the two levels at the tower's base, and flats rise above them.

Constructed between 1956 and 1958 under architect Drago Ibler's direction, this building responded to Zagreb's post-war housing shortage. It represented a shift toward modern construction methods during the city's recovery and urban development phase.

Locals call it the "Wooden Skyscraper", though the name comes from its light, wood-like cladding rather than timber structure. The complex pairs a two-storey commercial wing with an eight-storey residential tower, with shops at ground level and offices in the tower's two-storey base. It has been a protected cultural good (Z-1472) since 2004.

The building sits on Hrvatski narodni vladari street in a central location with convenient access to Zagreb's public transportation. Its position in the heart of the city makes it easy to reach nearby shops and services on foot.

The nickname 'Wooden Skyscraper' comes from the building's timber-clad upper tower, which rises eight storeys above a two-storey commercial base. The complex was built as the Autocentar building, with shops at street level and offices on the two floors at the tower's foot. It has been a protected cultural good since 2004.
