The Vision

A district designed to turn proximity into energy: bringing dining, entertainment, residences and public life into one connected place.

The Master Plan

Everything connects here

Explore the master plan
Toyota Arena, photographed on site

The audience is already here. 11,000+ seats, 300+ event nights a year, at the center of the district.

Toyota Arena opens into the Plaza. Water, patios, screens and public space turn movement into time spent here.

The front row. Destination dining on the Plaza, facing the arena. From seat to table without leaving the district.

Extends the day. Coffee, wellness, casual dining and service retail, built for repeat visits rather than one-time arrivals.

Phase One begins with Edge and Echo. The master plan extends across additional residences, hospitality, entertainment and public space.

Toyota Arena brings the audience. Capital City extends the experience.

Daily rhythm

Capital City is not dependent on the peak.

Arena nights are the peak, not the model. Residents, offices, the airport, the mall and the convention center keep the district busy across the day and the week.
