"I'm sure it will win," Nicholai Conradi, who often skateboards alongside the City Hall told newspaper Aftenposten. "Which other building in the country is better?"

Residents of Bergen and Trondheim, for example, are likely to come up with some candidates. But Oslo's City Hall was the clear favourite among those who voted in the competition sponsored by Norway's building industry.

It grabbed 30.4 percent of the vote. The next-closest candidate, the residential complex known as Ullevål Hageby, won 15 percent.

That was followed by the Ekeberg Restaurant, with 13.6 percent and the Holmenkollen Ski Jump, with 12.8 percent.

Competition leader Leo Nygænen said he was pleased with the participation. "We had more than 1,000 votes in Oslo, plus around 11 from Minnesota, which all went for Holmenkollen," he said.

The new Telenor building in suburban Bærum won the competition in Akershus County.
