It would be easier for things like crutches to be picked up and returned with its new location.
The new building will also be home to a workshop where equipment will be repaired and maintained.
"We're designing a whole work flow," said Mr Freeman.
He said it had taken a couple of years to get to an agreement and finalise the design. The 330 square metre building is expected to be completed in four to five months.
The building's construction was funded by the Wairarapa Community Health Trust, which is separate to the DHB.
Derek Milne, chairman of the Wairarapa District Health Board, said it was great that work was starting on the construction. "This is for the people who keep the place running."
Dr Milne and new members of the DHB were also welcomed at a powhiri yesterday morning. He and board members Ron Mark, Ronald Karaitiana and Alan Shirley were welcomed at a traditional powhiri before the first board meeting for 2014.
The traditional Maori welcome was coordinated by Director Maori Health Stephanie Turner and included representatives from local iwi and senior DHB staff.
Dr Milne acknowledged it was a great honour for he and his fellow board members to be entrusted with ensuring DHB funds were spent in ways that best benefit the Wairarapa community.
