To celebrate the Green-tech team released 50 balloons with messages attached, in the hopes of finding out how far the balloons travel.
The company's purpose-built premises at Rabbit Hill Park were consulted on by Carter Jonas Planning Consultants, designed by Lawrence Hannah Architects and built by Sutcliffe's Construction. The move was two years in the planning, with the build costing more than £3m to complete.
Green-tech also worked with long-term industry partners and landscape architects Smeedon Foreman to create a landscape design that complemented the development and achieved Green-tech's ecological and biodiversity goals.
Rabbit Hill Park, owned by Green-tech's Richard and Rachel Kay, will house Green-tech's £10 million business, including head office, warehouse and distribution facility. A number of the park's offices have also been let out and meeting rooms are available for local small businesses and start-ups to hire.
Green-tech chairman Richard Kay commented: "It's a great personal achievement for Rachel and I and we're delighted with the finished result. It's a big site with a number of buildings but they have been completed sympathetically and fit in well with the local landscape.
"We've had fantastic support along the way from our key suppliers and I'm delighted with the work of Sutcliffe Construction. The new site has been well planned and built and will have a number of facilities and services to support local businesses and people.
"We have already had to increase our workforce and have further plans to recruit. I am confident that Rabbit Hill Park will support Green-tech's future growth as well as supporting the local economy."
Managing director Rachel Kay added: "I am thrilled with the results. 2015 has been a bumper year for Green-tech and moving our 50 strong team, two dogs and over 6000 product lines into Rabbit Hill Park without missing a beat is the perfect end to an amazing year.
"Leaving our current premises in Nun Monkton, York after 14 years was bitter sweet but we have ambitious plans to double our turnover to £20 million by 2020 so we really need bigger and better premises and facilities. I'm looking forward to the next chapter in Green-tech's story."
