225 W. Madison County Attorney’s Office – Maricopa County, AZ

225 W. Madison, formerly known as the Madison Street Jail constructed in 1985, is a unique design opportunity to resurrect a decommissioned jail facility that has been vacant for 10 years and re-purpose through adaptive re-use as a Class A office building. The design of the 278,775 SF building transforms a secure, closed and fortified structure designed to separate individuals from society and completely reinvents it as an open, welcoming work space with daylight and views. Re-purposing 225 W. Madison provides for an enhanced civic fabric of Phoenix with an active and vibrant office facility for county employees thereby refreshing a lifeless and vacant segment of the Phoenix urban core. The economic driver was the benefit of consolidating leased office space into this county owned facility adjacent to the Maricopa County Courts Complex. 

The CMAR construction contract was awarded to Layton Construction, with the architectural design delivered by DLR Group Architect of Record.

Inspired Networks was contracted by Maricopa County’s Facilities Management Division (FMD) for the design of the infrastructure and communication systems.
