Cornwall may become home to a new ecologically sustainable five-star hotel complex if the developer, Roseland Peninsula Homes, is successful in its planning application.

The 130-bedroom hotel, to be called The Coast, will feature a public cinema, a restaurant and cafe, retail units, a conference centre and a Sky Bar. It will also include a health spa and a gym.

The complex is designed by architect Richard Hywel Evans in collaboration with environmental engineering firm Atelier ten.

Paul Bateman, planning partner for Laurence Associates, the project's consultants, said: "Right from the outset the developer instructed us along with the architect to produce a proposal that was low energy and sustainable."

Sustainable features will include passive ventilation, controlled solar gain and ground source heated exchange to maintain the hotel's internal temperature without the need for heating or air conditioning.

The complex will also use grey water recycling, roof-mounted solar heating, a combined heat and power unit, irrigation for the hotel's garden courtyard and internally mounted wind turbines. It will be built using entirely renewable materials including natural stone, slate and timber.

The Coast is set to replace the existing Kilbirnie and the Edgcumbe Hotels, which currently operate on the site. A contractual agreement between the developer and the owners of the hotels outline the plans to demolish and redevelop the site.

Roseland has already secured the funding necessary for the redevelopment through a consortium of private investors.

Following a "very supportive" public consultation the designs are now being finalised in order for a planning application to be submitted in the next four weeks.
