Blue City is a 21st century community for 200,000 people in the Sawadi Al Batha peninsula of Oman. The master plan, originally designed by Foster + Partners, was a concentrated 23 km2 development in which Brown Sardina provided conceptual and design development services for a 5-Star hotel, two apartment and condominium communities, two retail developments, and the community town hall and plaza. Additional services included alternate feasibility studies, circulation and parking strategies, native planting palettes, and site grading alternatives.

While individual site plans were unique each respected the Omani culture and traditions through the material and pattern selections, natural and manufactured shade options, and water as a focal element. Amenities such as pools, fountains, plazas, and playgrounds were designed to be independent, but supported the network each of the development areas.
