Hi Sylvana, this project was completed in 2010 and at the time this was the approximate pricing for the staircase: 1 flight of steel and solid timber treads, $15,000 plus galvanised steel poles $100 per pole. Labour and carpentry approximately $2,000. Hope you find this information useful.
This or That: Carpeted or timber stairs?
Need ideas for under stairs space
Stair safety (toddlers)
How do I use the area under the stairs?
