Riga chief architect Gvido Princis previously gave a ''thumbs down'' to the project.
The head of the Riga Municipal Construction board Inguss Vircavs claimed to members of the press today that the construction board have not received the necessary documentation for adjustments and corrections made in the project's technical details, and thus denied the project altogether.
The Museum of the Occupation of Latvia, built in 1971 to mark the 100th birthday of Lenin, is one of the most memorable historical buildings in Riga.
The museum has seen 25 years of independent Latvia, but renovation efforts have been limited.
Some prefer the museum to remain as it is, while plans have been in motion to add a white 'Future home' section to the building. Clashes between supporters of the two options have escalated during the last year.
