As an important urban infill project in Southwest Florida and a catalyst for future development in the government center, this design responds to the need to be a sustainable, survivable, yet open and inviting public building that maintains all critical functions 24 hours a day, 365 days a year, during any event. The project is sited on approximately 69,184 square feet of property and consists of 6 stories that house approximately 102,000 square feet of program, with the first 3 levels parking 200 vehicles. It is also LEED Certified.

Developing a Site Strategy
In order to create a visual icon for the public, a vertical entry plaza anchors the project’s Southeast corner to the edge of historic Payne Park. This public plaza further acts as an overflow space for both public meetings and media events.
The South-facing façade is a simultaneous response to the harsh Florida sun as well as adjacent Payne Park. A secondary screen wall serves to functionally shade the building, while concurrently framing view vistas out and towards the park-creating a unique, urban backdrop for the on-looking park goer.
Ultimately, through balancing sustainability and survivability issues, the project is intended to respect the tradition of the Sarasota School of Design Syntax and integrate seamlessly into the City’s existing downtown urban fabric.
Programming Complexity – A House for Many Functions
A Police Department Headquarters is innately a complex program. Multiple critical civic programs must be housed under one roof to create a unified point of service for the city at large.
The program includes:
Police Headquarters, Police Administration, Records, Booking and Intake, Bulk Evidence Storage and Processing, Training Space, Swat Team Planning, Physical Agility, Special Vehicle Storage, 200 space Parking Garage, Community Meeting Rooms, and various other elements. The facility is designed with approximately 13% shell space and for future, vertical expansion.
High Performance Construction Techniques
Due to the critical nature of the program, the building must meet stringent survivability criteria. Designed to meet the challenge of a Category Five storm and still maintain operations, the primary structure is a post tension concrete building clad with architectural precast and high performance, impact resistant glazing systems to mitigate catastrophic events. The South-facing screen wall shades the building, but also provides an added layer of impact and blast protection.
Open and Inviting Public Safety Architecture – Creating Positive Work Environments
In order to promote sustainability, the envelope is equipped with high insulation values and all glazing is shaded by various solar protection systems. Light shelves are employed to bounce indirect light further into the work spaces, while large overhangs shade the upper floors from the Florida Sun. To further the energy savings, day light sensors and occupancy sensors are utilized on interior lighting fixtures.
Sustainable, Survivable Design Objectives:
Day Light and Views

• Solar Shading and Fixed Louvers
• Reduce Long Term Operational Cost with Water Cooled Chillers
• Design High Performance Exterior Facade
• Use High Efficiency Light Fixtures, Occupancy, and Light Sensors
• Capture Site Water Prior to Discharge and Reuse
• Reuse of Existing Downtown Urban Site
• Connect into Local Public Transportation Infrastructure
• Efficient Water Use Fixtures
• Grey Water Reuse
• Reflective Roofing
• Use of Low VOC Materials
• Use of High Recycled Content Materials
• Use of Slag and Fly Ash in Post-tension Concrete
