Hamilton founded Halo in his mother-in-law’s spare room and currently employs about 200 people in two Stowmarket offices.
It was initially Ipswich Town’s shirt sleeve sponsor from 2023, but now has its logo on front and centre on the home kit.
“Ipswich is the natural choice. Half our team live in Ipswich, within a 10-minute walk of our new location,” he said, explaining the move, which will begin this spring.
It will continue to have an office in Stowmarket – keeping the one with a slide, bar and pool table.
“Why the Willis Building? It’s iconic – we had a look around many buildings, and there was just something different and we thought we could see ourselves here for the rest of our years.
The Willis Building celebrated its half century in 2025, and Hamilton said he could “see that this will be Halo’s home for the next 50 years”.
The all-glass exterior building in Ipswich was opened with a roof garden and an indoor swimming pool, which is still there but is not in use.
It was described by another world-renowned architect Zaha Hadid as “a timeless classic – a vision of what is possible”.
