PHOENIX -- The moment the Brewers depart Maryvale Baseball Park at the end of next month, the dirt will start to fly.
In unveiling renderings of the upcoming renovation of their Spring Training home, the Brewers added additional detail to their planned overhaul of the complex. Here is a rundown of the upgrades expected in place by this time next spring:
Brewers unveil Maryvale overhaul, set for '19
New clubhouse building: The centerpiece of the project is a new, two-story building to be constructed from home plate to the existing Major League clubhouse. It will contain locker rooms, a massive athletic training and strength training space, video facilities, plus a flagship retail store, ticket office and additional restrooms to serve the main stadium. In the process, the stadium's first-base concourse will be significantly widened, easing the bottleneck formed by fans entering the gates. The second floor will house offices for the baseball operations staff, with a balcony overlooking the field.

The addition will double the current clubhouse and office space on site, from about 41,000 square feet to 82,000 square feet.

"The mindset of everybody in the organization was if we're going to stay in Maryvale, we have to start over with the buildings," Brewers manager Craig Counsell said. "That was always going to be the mindset."
New entry plaza: The main entrance, currently in the right-field corner, will be moved to behind home plate. That area will be anchored by the retail store, which will be open on non-game days as well as game days.
Repurposed Major League clubhouse: The existing clubhouse will be renovated to include facilities for psychological services, sports science, maintenance, grounds, a new right-field gate, ticket office and vendor commissary. The upper level of the existing building will become business operations offices with new finishes.
Batting tunnels: A new eight-lane batting tunnel will be constructed immediately south of the renovated Major League clubhouse. Two of the tunnels will be fully enclosed and air conditioned. 
Practice mounds: Currently, the Brewers have four mounds behind the main clubhouse and four more near the Minor League complex, but the renovation will feature eight new shaded pitching and catching mounds next to the batting tunnels.
Agility field: Tucked into the middle of the new complex will be a high-performance "agility field" of primarily natural grass.
The batting tunnels, mounds and agility field will all be located between the stadium and existing parking lots. It is expected that fans will circulate through these areas as they walk into the stadium, allowing them to interact with and watch players as they prepare for games.
A mirror of Miller Park: A high-performance natural turf practice field will be constructed at the site of the existing half-field to the east of the current Major League clubhouse. It will have dimensions and layout matching Miller Park in Milwaukee.
Visitors clubhouse: A new clubhouse for the visiting team and umpires will be constructed on the third-base side of the stadium and will double as a commissary for cooking, refrigeration and dry storage.
Field improvements: The main stadium outfield surface and the existing Major League practice field will be completely resurfaced with new turf, clay and warning tracks.
New scoreboard: For the first time in two decades of Maryvale Baseball Park, the Brewers will be able to show more than the line score and the batter's name. A new scoreboard will replace the relative antique currently in left field.
