“It is such a small site, but SDA made it work and it looks great at night when the traffic on Sunset Boulevard is driving by.”

“SDA have worked with Audi for the last 15 years, both as Architects and Brand Guardians. They have been proactive in their approach to design and development of projects, coming up with innovative solutions where required and being key to value engineering projects to achieve design budgets. In addition to this, they have sourced materials and products from UK suppliers to improve quality of finish achieved and reducing overall cost of construction. Anthony Henson excels in terms of managing a very challenging relationship with the Audi AG corporate identity department.”

– Network Development Manager, Audi UK

“A representative of Audi AG spent around three hours on site today and at the end commended the building. This culminated in him saying in terms of location, construction and the team on site that he believes that we have one of the ten best sites in the world. Needless to say that I want to thank all of you and your teams for delivering this great result.”
