Around 250 employees have already made the short move from Knutsford with the remaining 20 set to switch offices by mid October.
"We are really looking forward to moving to the new premises," said the firm's personnel manager Tricia Walker.
"It is an opportunity for us to be together under one roof and we're looking forward to working with the Northwich community."
Eurocamp, which won the prestigious award for Investment in People three years ago, announced the £1 million move in February.
Since then, staff have been working behind the scenes to make sure things went as smoothly as possible.
"It was planned so that it was a seamless move," said finance director Bob Baddeley.
"There was some disruption, but we were still able to take calls."
Customer sales and marketing staff were the first to move, two weeks ago.
They finished early on Friday and during the night, the main computer was moved to the company's new home.
And Eurocamp arrived for work last Monday to find out their favourite plants had survived the move.
"A lot of the staff didn't want to leave the plants behind that they had nurtured for so long in Princess Street," added Mrs Walker.
