Adare Manor is reportedly set to lose its hosting of the US Open in 2018
Course architects Finglas architects Pogson, Anderson & Woodman with Moyse Ivo Michelazzi McDougall are behind the plans for Adare Manor.
The 2027 Ryder Cup tournament will be held at the course outside Limerick.
Promoter Paul Morris said he was “delighted” with the success of the sale of the course.
“The venue will now become a permanent asset to the Limerick economy with the Ryder Cup being the catalyst for sustainable tourism growth,” he said.
In July, Morris told BBC Sport Ireland that the Adare’s primary target was to host the Ryder Cup in 2027.
The land has been sold to the Adare Manor consortium, which will become the majority shareholder in the company.
Finglas Architects had already been appointed to revamp Adare Manor for the US Open in 2018.
The Finglas practice, which counts Michael Campbell among its former clients, also has a new contract to refurbish home city Limerick’s Half Moon bar.
