We were commissioned to do historical research and use the results to plan the reconstruction of the original roof structure and ornamentation. As requested, we prepared the plans for the partial reconstruction, with original materials, of the roof of the ornate corner house designed by Géza Kármán and Gyula Ullmann in 1900. The works were completed in 2024. The roof of the building standing in one of Budapest's most luxurious downtown squares is now more beautiful than a few years ago, but it is still far from its original splendor. Perhaps we can continue the work.
