He moved to Wellington in 1999, and his work in the latter part of his career concentrated on projects for the dairy industry, firstly for Anchor and then Fonterra. These large projects offered him the opportunity to exercise his skills in large-scale planning, negotiation, bargaining and strategising situations to the best advantage of his clients.
All four of the Lonergan boys were fliers. Barry particularly flew in the early years of his career as many of the sites he worked on were difficult or time-consuming to get to. He was known as "Biggles" in those days.
The death of his younger brother, Patrick, in a helicopter accident was a great loss. After Patrick's death, Barry's interest in flying waned and he took to motorbikes.
Everything he did was done with great enthusiasm, but perhaps not the caution a situation might have deserved.
A serious accident was the final straw for his back, which had endured plenty of punishment already from the trampolining, long distance running, and a series of car accidents all of which complicated issues with his spine and led to long-term pain management issues that dogged him for the rest of his life.
All of these events were met with a strong will to be productive and create solutions to enable him to control his life.
He was enormously proud of his children and their achievements. Daniel, now in New York; Morgan, based in Adelaide (but mostly working in Europe); and Kate in Melbourne. The three grandchildren were also a great joy to him.
Barry met his partner Robyn Steele nine years ago. They had much in common and enjoyed catching up with their collective five children, scattered all around the world.
Barry will be greatly missed by Robyn and Daniel, Morgan, Kate and his grandchildren. As well as by his brothers Michael and William, sister Josie and many friends. He will be missed as a talented architect and a thoroughly likeable character.
