The goal of this renovation was to replace four external staircases of a 50 year old apartment building next to Cheltenham Beach in Devonport, Auckland. We went to have a look at the stairs and soon realised they were on the verge of collapsing due to advanced corrosion in both the steel stringers and the concrete tread reinforcements. 

​

As the stairs were the only access for some of the apartments, we decided to do the work in stages to lessen the impact for the residents. Initially, we removed the balustrade and erected temporary barriers, as well as provided temporary treads to replace the most dangerous and broken ones. 

​

We were asked to make the new stairs as close to the original ones as possible. In order to achieve this, we chose to renovate the existing balustrade, and took samples of the broken treads to a concrete paving specialist for the closest match. 

​

The frame of the stairs, all the concrete treads, and the landings needed to be replaced entirely, so we fabricated four new stairs in more robust material. We also made sure there were no areas for water to pool, which future proofed them for the next 50 years. 

​

Finally, when it came to the installation, we removed the old stairs and installed each new staircase with the refurbished balustrade in a single day to ensure the residents could access their homes when they got home from work.
