We are a structural engineering practice with considerable experience in the design of both building structures and facades. The practice was founded by Tim Macfarlane in 1985 as Dewhurst Macfarlane and Partners and the current name was adopted in 2012.

The main office is in central London with an associated office in Shanghai employing an overall compliment of 15 staff. The practice has worked on projects ranging from small bespoke sculptural assignments to major public buildings and has practiced in the UK, Europe, Asia, Middle East and North America.

The projects we have completed and enjoy working on range from bespoke private commissions to medium size building projects and large-scale façade projects in the commercial, private and public domain.

At GL&SS we work hard to ensure both the design and client teams that we support are provided with engineering proposals that exceed their expectations. We typically enjoy challenging design projects which required solving complex structural problems that explore the limits of construction. We also often seek to employ materials that achieve the most cost effective and environmentally conscious solution.

Tim Macfarlane has been a leader in the innovative use of glass as a structural material for over 30 years and has been involved in complex projects that span from small bespoke glass installations to large scale frameless glass assemblies.

Tim pioneered the use of structural glass on the original Apple Flagship stores in New York, Chicago and San Francisco. This sophistication of engineering has set a standard for all further stores that Apple continue to develop worldwide.

The University of Chicago School of Business and the Mori Art Museum Pavilion are also projects that have attracted international acclaim. 

Our collective team has a diverse array of skills from various interconnected disciplines including, façade engineers, architects, structural engineers, sustainability and façade maintenance consultants.
