Mark Boler, who owns the Cheshire complex with business partner Gary Corbett, has boosted staff from 100 to 200 after creating an 81-bedroom hotel and two new restaurants, among other improvements.
Backed by the Royal Bank of Scotland, the investment and refurbishment programme is aimed at attracting short-break tourists from further afield and giving the independent resort a competitive edge against rivals.
Mr Boler, whose late father Stephen was a well-known north west entrepreneur and Manchester City shareholder, said he would spend between 12 and 18 months ensuring Mere is a success before considering further expansion.
“I’d be looking for other opportunities to do similar somewhere else – hospitality, bedrooms spa and golf, “ he said.
“My ambition is to grow this brand.
“I have made mistakes trying to do three or four businesses at the same time.
“What my dad said to me was, ‘if you are good at something, stick to it’ and that’s what I intend to do.”
The Boler family acquired Mere in 1984.
Mark Boler acquired the business in the late 1990s and said that the redevelopment of Mere over the last 12 months has seen the realisation of plans formulated over more than a decade.
Among new appointments at Mere is resort general manager Graeme Nesbitt, who previously worked at the Cameron resort on Loch Lomond.
