Work has started on developing the site of a former Fife paper mill that closed in 2015.
Kingdom Housing Association says 85 affordable new homes for social rent are being constructed where the former Tullis Russell paper mill used to be in Glenrothes.
Those affordable homes will cost £14.6 million to build.
The properties will be part of a larger residential led mixed use development.
850 homes are expected to be built, alongside business, industrial and retail units.
A range of housing will be constructed including bigger family homes and properties suitable for older people and tenants with particular housing needs.
The site will be developed in several phases by a range of different housebuilders.
Kingdom Housing Association is working with Advance Construction and Campion Homes, with the association securing the affordable housing part of the project.
Kingdom Group Chief Executive Bill Banks said: "This exciting new development of affordable properties for social rent in Glenrothes provides residents with homes which are not only safe and secure but also highly energy efficient.
"One of Kingdom’s strategic objectives is our commitment to sustainability and all of the new homes will benefit from low carbon heating and solar photovoltaic panels and public electric vehicle charging points will be provided."
He also said: "I’m delighted that the development at the former Tullis Russell paper mill site allows us to continue working collaboratively with Fife Council, Campion Homes, Advance Construction and Oliver & Robb Architects to help meet the current housing needs in the area."
