The offices "herald a new era for the company, which will better connect offices globally with video conferencing calling available in every room and every member of staff now working from a laptop".
Chief executive officer Jim Hagedorn will officially open the new offices on May 23 2016.
Miracle-Gro UK chief executive Sheila Hill said: "2016 marks a significant new chapter in the history of Miracle-Gro’s presence in the UK. Our office move to Frimley demonstrates two things: firstly, we want technology and innovation to lead the way in everything we do. Secondly, supporting grassroots charities is, and always has been, at the heart of everything we do.
"We will always beat the drum for horticultural therapy, which has a valid and important contribution to make to society. We have already started working with local charity Frimley Health to provide greener and brighter spaces at Frimley Park Hospital, giving patients and staff the benefits of relaxing gardens can create a healing atmosphere.
"This isn’t just an office move for us – this is the start of something very exciting."
International planning head Steve Fuller said: "We wanted an office with the ‘wow’ factor, and the open plan space we started with was the perfect blank canvas. Technology was central to our approach, and now every member of staff has a laptop, we have state of the art video conferencing facilities in every meeting room and we have opted for the highest spec possible to future proof the office."
The building conversion was designed and installed by CBS Office Interiors.
Vicky Page, Consumer Relations Manager said:
"Godalming is a beautiful place to be and we made many connections with some of the fantastic local community groups and charities. We will continue to support our existing connections but look forward to meeting with some new groups in and around Frimley, we already have plans to help Frimley Hospital improve their 10 ward gardens through our newly formed relationship with Frimley Health Charity."
