Those who attended the event watched on as the egg, which divided the existing and new spaces, was removed to reveal the new area.
The extension sees the agency’s head office in Hartlebury almost double in size, and it will include larger creative and production spaces.
The extension will encompass two areas. The first will house a construction workshop area complete with its own loading bay, which can be used to build custom sets and exhibition stands.
The other area will include a set, scenery storage area, set covering area, technical preparation space and two loading bays.
Dale Parmenter, CEO, Drp said: "The new expansion has happened a lot faster than we anticipated, it will allow us to increase our capacity, service levels, and quality for our clients.
"The site is undoubtedly the largest and most comprehensive corporate communication complex in the UK, if not Europe. This investment is part of an on-going programme to realise our vision of being the company of choice for presentation and communication solutions globally."
Drp recently appointed Andrew Grierson as its new project manager.
