The project aims to transform Studio Two at the venue to create larger breakout conference rooms.
The changes are set to help the centre compete more effectively for major national conferences in Harrogate.
Members of North Yorkshire Council are set to receive an update on the plans when the council’s executive meets next week.
If approved, the council will move forward with awarding a construction contract, with building work potentially beginning as early as this summer.
The redevelopment of Studio Two would create breakout spaces for around 1,200 delegates and is expected to generate an additional £1.7 million a year for the local economy.
The project is currently estimated to cost about £9.4 million following design refinements.
According to the council, the investment could be repaid within around 10 years through increased income generated by the upgraded facilities.
Gareth Dadd said the convention centre plays a significant role in supporting the region’s economy.
“The Harrogate Convention Centre brings thousands of visitors to North Yorkshire every year and contributes more than £45 million for our economy through the retail and hospitality sectors.
“It is a key economic driver which promotes both the town and North Yorkshire on a national stage.”
He added that improving Studio Two could help the venue remain competitive in the conference market.
“Developing Studio Two by creating larger breakout conference rooms to complement the existing 2,000-seater auditorium can ensure the venue stands alongside the very best centres of its kind in the country,”.
The convention centre, which opened in 1982, is the only facility of its kind in North Yorkshire and includes one of the UK’s largest purpose-built auditoriums as well as more than 13,000 square metres of exhibition space.
However, the lack of large breakout rooms has limited the venue’s ability to host some larger conferences.
Paula Lorimer said the proposed improvements would strengthen the centre’s offer.
“We are really excited about the proposals for Studio Two and there’s no doubt that the investment would significantly enhance what we can offer as a high-quality venue and destination for clients.
“The creation of dedicated breakout conference rooms will open up new revenue opportunities that benefit the town’s hotels, restaurants, cafés and shops.”
