Turrets at the Dunedin Railway Station may soon match what was intended by architect George Troup.

The original design featured copper tiling and this was being implemented as part of the restoration of the station, Naylor Love construction manager Paul Stevenson said.

Copper fish-scale tiles, made by hand at Allan's Sheetmetal and Engineering Services, were deployed to replace zinc tiles, and they would turn green in time as they oxidised.

The Dunedin Railway Station opened in 1906 and it is a category 1 historic place.

Naylor Love has been leading the restoration project, which includes repairs to the roof, windows, walls and Oamaru stone masonry.

Some of the work is intricate.

Mr Stevenson said many roof tiles were taken off site, cleaned and restored to use.

Others were replaced by new tiles with an aged appearance.

The Dunedin City Council had budgeted $6.4 million for the three-stage project.

The council this year allowed for an increase of $1.6 million to complete the work.

Mr Stevenson said the second stage was due to be completed in September and the final stage in August next year.

City council property services group manager Anna Nilsen said the building was a landmark for the city and the work being achieved was well worth the investment.
