The head of the British Council for Offices' (BCO) Midlands and Anglia chapter has hailed a wave of interest in Birmingham following the recent annual conference in the city.
But Lee Jones warned the body needed to attract more office occupiers to its committees to give the BCO a broader and more representative spread of people to reflect changing trends in the market.
The BCO has held an annual conference since its inaugural event in Bristol in 1992 and the return to Birmingham ended a 14-year hiatus following its first in the city in 2000.
Reflecting on the conference's impact, Mr Jones, a director with consultancy Aecom, said: "Those delegates who don't work far outside of London were very surprised with Birmingham and impressed with what it has to offer, in both office stock and developments, which is ultimately the reason we applied to have the conference here.
"Birmingham City Council has been pretty forward thinking in terms of the city's enterprise zone which was another thing that impressed and struck a chord.
"I guess many of the delegates hear a lot about Manchester so the BCO is helping to promote Birmingham and keep pushing the city.
"The economic value to the city is a tough one to estimate but I know agents were very busy during the conference and I know of one developer who used the event to engage with funders.
"He has now secured a buyer for a building as a direct result of the conference."
The event, held mainly at the ICC, attracted just under 550 delegates and 700 to the conference dinner.
The main plenary sessions heard from guest speakers such as Sunday Times political editor Isabel Oakeshott, adviser to the London Mayor Gerard Lyons and Derwent London chief executive John Burns while fringe events covered a broad range of topics including the technology and media market and future cities.
There were also tours of key buildings in the city such as Brindleyplace, Fort Dunlop, Snowhill, the new library and the Custard Factory.
Mr Jones is due to stay in the chairman's seat for another 15 months.
Looking ahead to the rest of his tenure, he said: "For us, the main focus is going to be on the occupier rather than investor or developer.
"It's about making investors and developers connect with occupiers and getting occupier representation on the BCO's committee.
"The building process has got to be reversed whereby we start with the occupier instead of seeing them just as the end user.
"This will only help with new-build developments and it's about understanding what occupiers want and need.
"The vast majority of UK occupiers, about 25,000 companies, have under 10,000 sq ft so it's that voice we're trying to get out there. Many committee members come from a real estate background but we would rather have that diversity."
