The cultural center was built by the owners of the Láng Machine Factory in 1932 for the education and entertainment of workers and their family members. The institution, which has been operating continuously since then, is a crucial element of the Angyalföld residents’ identity. In 1970, a 456-seat theater and a newspaper reading room were added to the building, designed by György Tokár. In 2018, the municipality decided to upgrade and modernize the energy supply of the facility. From the outside, the original washed gravel façade panels were insulated, while aluminum curtain wall elements and windows with thermal bridge were replaced with modern ones. The architects boldly re-considered the façade: they covered the insulation with small-block clinker brick with the knurled back facing outwards. Now the uniform new façade design enhances the space- and mass-forming effect of the building and its place in the urban context, so the widening space in front of the building can become a real urban place. It is even more typical for the interiors that architects have sought to preserve the original materials and structures. The artificial stone surface of the entrance ticket office, the beautifully laid Mezőtúr brick wall of the Great Hall and the lobby were all preserved, and the paneling of the Great Hall was reassembled to its former place after renovation. The contemporary use of materials and colors does not disturb the original overall design by György Tokár, because the designers reshaped one of the beautiful but hidden opuses of Hungary’s post-war modern architecture with exemplary compassion, respect, and elegance.
