Developer Land & Lakes, backed by Kingmoor Park Properties Group in Carlisle, has been granted planning permission for more than 1,000 holiday lodges and affordable houses along with a hotel in Penrhos, Holyhead.
The application consisted of three separate elements known as Penrhos, Cae Glas and Kingsland.
The Penrhos proposals were for up to 500 lodges and cottages and all-weather facilities including an indoor sub-tropical pool and spa as well as water sports centre, beach cafes and restaurants.
There will be a new visitor's centre, 72 acres of publicly accessible open land and a coastal path.
At Cae Glas, 315 lodges and a 75-bed hotel will be surrounded by 96 acres of coastal nature reserve, visitor centre and outdoor sports facilities.
At Kingsland, there will be 320 houses built to Code for Sustainable Homes level 4; 50% as an affordable provision to enhance the planning gain for the island.
The Cae Glas lodges and Kingsland dwellings would only be delivered if they are initially used as temporary accommodation for construction workers involved in the Wylfa new nuclear power station project. The development could well play a key role in accommodating a proportion of the anticipated 6,000 nuclear construction workers and subsequently deliver a long term legacy by way of employment in the growing tourist industry and a substantial affordable housing provision.
Land & Lakes have been working with landowner Anglesey Aluminium Metals and the Isle of Anglesey County Council for three years to develop the holiday blueprint which could create over 600 jobs for the area and leave a lasting viable economic legacy for the town and the island.
Richard Sidi, chief executive of Land & Lakes, said: "It has been an intense three years of assessment and planning but we are confident we have a project that ultimately will be deliverable, make the most of the outstanding natural beauty of the area whilst being sensitive to the wishes and aspirations of the local community."
Manchester-based HOW Planning acted as lead consultant on the project, preparing and coordinating the planning application and the environmental impact assessment. The rest of the team was made up of lead masterplanner and landscape architect Planit-IE, traffic advice by Curtins Consulting, heritage architect Purcell, ecology consultant TEP, together with Regeneris Consulting, Capita Symonds, WSP Environmental, Gwynedd Archaeological Trust, Edmond Shipway and Colliers International Destination Consulting.
