My father, the architect Alan Lamond, who has died from cancer aged 60, was a global leader in airport design. He shaped some of the world’s most ambitious and highly regarded airports, collaborating with other architects including Norman Foster, Zaha Hadid and Richard Rogers. His expertise in functional airport planning and layout was a major influence on projects including Heathrow terminal 5, Beijing’s new airport, King Abdulaziz international airport in Saudi Arabia and Dublin terminal 2. His award-winning work can be found in more than 30 countries.

Alan was born in Glasgow to Norman Lamond, who managed a number of manufacturing businesses, and Susan (nee Budge), a teacher. After attending Greenock academy, he studied at the University of Strathclyde for degrees in architectural studies (1977) and architecture (1979). These were followed by a master’s in architecture and urban design at the University of Washington, St Louis, Missouri, in 1984.

Between his studies, Alan spent two years in Zambia, designing public buildings, and worked at RH Partnership in London, where he met Brenda Brown. They were married in 1987.

In 1990, Alan moved to Pascall+Watson in London, where he remained for more than 25 years, helping to transform the practice into a leading aviation specialist. During that time, the firm grew from 25 people to more than 200.

As director of aviation at Pascall+Watson, Alan worked on 75 terminals at 65 airports. Recent projects include Al Maktoum airport in the UAE, Mactan Cebu airport in the Philippines and Jomo Kenyatta airport in Kenya. Closer to home, Alan helped design the Stansted airport master plan and Heathrow terminals 1, 2, 4 and 5.

He was twice made chair of the British Aviation Group, helping to establish the UK as a leader in airport architecture and engineering. Shortly after being diagnosed with cancer, Alan was presented with the organisation’s inaugural award for his outstanding contribution to British aviation.

Alan travelled the world, meeting and – in his gentle manner – charming thousands of people, including politicians, sheikhs and government officials. His work was his passion: he always said it was a privilege to do what he loved every day.

Generous with his time and knowledge, Alan was a mentor to many. He was modest, kindhearted and a calming influence.

He is survived by Brenda and their two daughters, Isobel and me, and by his father.
