Tim Macfarlane founded Dewhurst Macfarlane and Partners with Laurence Dewhurst in 1985 a partnership which developed over a period of 27 years into an international practice with offices in London, New York and Trinidad. In April 2012 the practice was renamed Glass Light and Special Structures Limited
The practice has been responsible for a wide range of challenging structures, where the structural and façade engineering are essential to the aesthetic, providing engineering design for arts, education, residential and public buildings in the UK and internationally. As well as working in conventional structural materials he has pioneered the use of structural glass in works ranging from small interventions to large cable-hung glass walls. He led the Dewhurst Macfarlane and Partners’ teams for projects that brought the firm success with the UK’s Institution of Structural Engineers including the Supreme Award for Structural Engineering Excellence for the Pittsburgh Convention Centre.
The Yurakucho Glass canopy in Tokyo, The Kimmel Centre in Philadelphia and the TKTS pavilion in Times Square New York have all attracted international acclaim and the glass engineering work on the Apple Flagship stores in New York, Chicago and San Francisco has set a standard for their stores worldwide.
