“They have just successfully completed the refurbishment of the Dining Room and conference area at the Royal College on time and within budget. We are delighted with the new room. We were particularly impressed by the careful management of the construction area which was within the main building. Their Project Manager made great efforts to work closely with our staff throughout the project to ensure no noise or other disruption to the College’s work. We would be happy to work with them again on a future project”

“On this design-led highly prestigious project, John O’Neill had in effect two very demanding clients, namely The Dorchester and Groupe Alain Ducasse.

John O’Neill’s Roundtable workshop driven culture bridged the gap between the clients, designers, sub-contractors and specialist suppliers. Despite working in close proximity to fully operational parts of the hotel, the well managed team, coupled with flexible and considerate working practices, had little detrimental effect.

I am pleased to say that the project was delivered on time and within budget, and met the high standards and quality always demanded the the Dorchester Collection.”

Ray Pask (Director of Technical Services (The Dorchester Collection) – Re. Alain Ducasse’s Restaurant
