Mosaic already has planning consent for converting the existing office building at the address, and its latest submission relates to consent for additional bedrooms for the proposed four-star Adina 110-bedroom aparthotel.

Neil Haining, director of Mosaic, said: "The proposed extension to the existing top floor level will create high level suites with exemplary view across Blythswood Square. The overall increase in scale of the existing building has been carefully balanced with the scale of the adjacent B-listed properties surrounding Blythswood Square."

The existing facades will undergo a full 'like-for-like' replacement, with the existing sandstone cladding being removed and replaced. An external courtyard area will provide a private external space for guests. A new feature entrance on West George Street will provide access to ground floor bar and restaurant facilities while a new extension accommodating additional bedroom suites, external terrace area and plant space is proposed within the existing rear parking courtyard.
