Controversial plans for 53 homes and more than 2,650sqm of commercial space in Lewes will be considered on Thursday next week.
The application by River Oaks Homes Ltd is for a site in Southdowns Road.
The dwellings would be a mixture of four- and three-bedroom houses, plus partments, together with offices.
People objecting to the proposal say the design is inappropiate and not in keeping with the character of Lewes.
A decision will be made by the South Downs National Park’s Planning Committee at Cowdray Hall, Easebourne.
