Jon Haagh

Director, Engineer

Director, with 18 years’ experience in New Zealand and the UK. I have led design for a range of structures – from sculptural and educational projects to multi-storey commercial, residential, retirement and carpark buildings.

I provide innovative structural engineering input that stands the test of time to projects for developers, architects, building owners and contractors who:

  • are designing or developing a new building
  • are planning alterations to an existing building
  • have received advice from their local Council about the seismic grading of their building

My diverse experience on a range of different building types from aquatic centres and large-scale commercial through to multi-storey residential means I can work up solutions to complicated problems. This sometimes involves finding new and better ways of doing things.

If you choose to work with me you can expect me to communicate clearly and regularly with everyone in the design team to make sure that I firstly understand your desired outcomes, secondly, I meet these as well as agreed timeframes, and thirdly that my work is coordinated with that of the architect.

I have worked as a structural engineer since 1999, both in Auckland and in London, where I worked for a medium-sized structural engineering firm on a mix of building types, a highlight was a residential project that was filmed for the TV programme “Grand Designs”. I joined Structure Design in 2006 and became a director on 2013.

  • Hazeldean Office & Carpark buildings, Christchurch. These projects were the first in NZ to use buckling restrain braces for their primary stability systems.
  • The Diocesan School for Girls Aquatic and Fitness Centre, Auckland. The development of post-tensioned timber box beams helped SDL win a design excellence award at the 2009 Timber Design award.
  • Tall Tree and the Eye, Anish Kapoor. The challenges on this sculpture, SDL’s first of several similar sculptures, were numerous, requiring intensive collaboration between teams and tackling unique problems, such as designing a bespoke shipping container to carry the sculpture from Auckland, New Zealand to London, England and finally on to Bilbao, Spain.

I enjoy spending time with my family, helping coach my son’s rugby team through the winter months and cycling in the summer.
