Plans are in for a major investment at an Anglesey mansion hotel that was built by a baronet.
The owners of Grade II Listed Chateau Rhianfa want to add a guest wing to the site.
The house was purchased in March 2011 and was transformed into a luxury hotel on the banks of the Menai Strait.
It currently has 27 rooms and last year submitted plans to add extra units.

But the application was withdrawn for some revisions and an updated plan has now been submitted - with CGI images from Gary Johns Architects revealing how the proposal could look.
The proposed location for the development is the currently disused tennis court located to the South/East of the main property and at a substantially lower elevation.
The new wing would include eight new bedrooms.
A planning statement said: "Construction of this bedroom wing will greatly increase the economic viability of the hotel and, in doing so, will maintain employment locally, increase tourism and safeguard the long-term security of the property and its associated historic significance."
It added: "The proposals have been demonstrated to be of high quality, yet with massing and scale that will be predominantly hidden from public view and subservient to the existing structures on the site.
"Revisions to the scheme have been guided by dialogue with the Conservation Officer and CADW to reach a satisfactory conclusion."
The plans have been submitted to Anglesey council.
The property dates back to 1849 and was built by Sir John Hay-Williams, Baronet of Bodelwyddan, as a gift for his wife Lady Sarah.
It was influenced by the couple’s travels in the Loire region of France.
