Signature Stairs was created in late 2009 with the coming together of two diverse backgrounds and experience in brothers Ian and Mark Crosher, sharing a belief in forming a joinery company that is not only proficient in what it does, but one that makes a difference.


  • Makes a difference for our employees by providing a place where they can challenge themselves and a play key role working on rewarding projects, while at the same time continuing to learn and grow in all areas of their craft.
  • Makes a difference for our clients by enhancing their staircase design and building experience on their project, getting the basics right while helping them achieve their aspirations through a focus on design.
  • Where possible, in consideration of the environment and sustainability, makes a difference in minimizing environmental impacts and promoting a more sustainable staircase joinery industry.

In staircase design and building there are many complexities and technical issues in the path towards a perfectly executed staircase project, and since our inception we have assembled a team of aspiring, enthusiastic and skilled staircase professionals to be able to meet these challenges. As a result we have excelled in a wide range of projects to date, whereby as a case in point, all of the staircase photography you see on our web-site are projects we have done.

Essentially, we offer a fresh approach in stairs. But the best part about us is that through our teamwork, innovation and our eye towards future trends in staircase design and building there’s is much more to come.

A bit about Ian and Mark;

Ian has an eye for detail and the mindset of craftsman. He understands intimately the intricate art in how even the most complex and challenging staircases are made, and has been building and supervising the production of fine wood products for 20 years. Not only is Ian a qualified carpenter and joiner but is also a registered building practitioner. Ian prides himself on his strong work ethic, personal integrity, and thoughtful management of a project during the building process. As a past CEO of a large staircase manufacturer operating in Victoria, Queensland and New South Wales, and now as Managing Director and Projects Chief of Signature Stairs, you can be rest assured you are in safe hands when engaging with us on your staircase project.

Mark has an astute sense of place in design and understanding of décor and eco-environments. He appreciates how these elements interface and bind together to create, whether intended or not, a design outcome. He is tertiary qualified in social sciences and economics, open space planning and natural resource management. Mark prides himself on his honesty, and the professional customer service clients can expect when engaging with Signature Stairs. As the Sales Manager for Signature Stairs, he enjoys seeing clients get the most out of their projects and the satisfaction that comes from seeing a project well delivered.
