The framework masterplan by the multi-disciplinary practice was for Bowness Bay and The Glebe on Lake Windermere, and includes public-realm work for an area suffering urban decline, said the firm.
The £10m masterplan offers guidance and advice on how to revitalise the area and includes a proposal for a waterfront park to help attract public and private funding.
Lake District National Park Authority and the Northwest Development Agency commissioned the masterplan, which includes leisure, retail and offices spaces, restaurants ad cafes, a hotel and cultural centre.
"If implemented the plan will enable the area to retain its popularity against other strong competing destinations," said BDP. "It will cater for needs of residents and give a massive boost to the local and wider north west economy."
