Key Projects

Client testimonial

  • “Dealing with John and the team was a simple process from start to finish. Nothing was a problem throughout the build, even the changes on site that were made, were agreed upon and done straight away. The complete build process was project-managed extremely well and the schedule was followed - we were in and operating at the time we had agreed. I would have no hesitation in recommending Coresteel to anyone for their building project. ”

  • “If Coresteel keeps their level of product and service where we experienced it then we have no hesitation in recommending them to others. Not only their pricing for the project was competitive but their communication and overall service level ensured that the the whole building process was low on stress for us. This gave us peace of mind to concentrate on running our everyday business elsewhere while the building project was managed by Coresteel.”

  • “Our experience with Coresteel Buildings was outstanding. We felt right from the very first meeting that our dream of owning our own building was going to become a reality as Coresteel made it their priority. We look forward to coming here to work every day and it's thanks to Coresteel for making it happen.”
