The project, overseen by interior design studio Alex Kravetz Designs, saw the revamping of the hotel's Park Lane entrance, Crush Hall, Silver Room and Gold Room. The Dorchester said that it is experiencing strong demand from events organisers to use the suite into 2012.
Alex Kravetz Designs fulfilled its brief to restore the rooms in their original palette of cream, white, blue and gold, with the addition of contemporary elements in the forms of technology and lighting.
Changes to the ballroom's main entrance include the replacement of carpet with marble. The Crush Hall features pineapple motifs, while the Silver and Gold rooms have been made into a single space. The ballroom can cater for up to 500 guests.
James Partridge, Dorchester Collection's director of group and event sales, said: "In current times clients look for outstanding venues with excellent service and stunning design.
"We are delighted to offer back to London a space which exudes the glamour of the hotel’s founding era and is yet understated enough to offer guests a blank canvas for any type of event."
