The three story main campus building, made of brick, uses the Neo-Gothic architectural style.
The school library is on the third floor.
Gene Lyons of Texas Monthly wrote that the design features "all reflect the college-prep institution the school was intended to be" when it was first built, citing the library's bay windows and the large lawn.
This building is across from Randall Park.

In 1979 the school was developing its permanent shop facilities in an addition that had a cost of several million dollars.
Previously the school had few industrial education course offerings, and no permanent shop facility was available.

A ground-breaking ceremony for the new science/performing arts wing at Woodrow was held on May 23, 2011.
 The $14 million, 40,000-square-foot (3,700 m²) structure was authorized in a 2008 DISD bond election.
 It is only the third expansion of the school's facilities in its 83-year history.
 (A boys' gym was added in 1953 and another addition was opened in 1979 in time for the school's 50th Anniversary Celebration.)
 The addition is three stories tall and located at the rear of the 7-acre (28,000 m²) campus near "Downtown Lakewood".
 It houses the new Performing Arts Academy and three laboratories for the Science, Technology, Engineering and Math (STEM) Academy.
 These academies are part of the school's redesign into four college prep academies which began implementation in the fall of 2010 as a four-year roll-out (the other two academies are the IB Academy and the Business & Entrepreneurship Academy).

The building addition was designed by Brown Reynolds Watford Architects with offices in Dallas, Houston, College Station and San Francisco.
 Principal Architect Craig Reynolds is a current Woodrow parent.
 It features two-story separate choir and drama rooms.
 The choir room has practice rooms and the drama room features a black-box theater, costume shop and prop facilities.
 A large dance rehearsal hall is also on the first floor.
 Three large science labs are on the third floor, along with new restroom facilities.
 The new addition replaces part of the 1979 wing, which cost $1 million.
 The areas replaced are former wood and metal shops - no longer needed with the school's new college-prep curriculum.
 The rest of the 1979 addition is being remodeled into a larger band hall and athletic facilities.
 There is room left for a future competition-size gymnasium to connect to this area.

As part of this same project, Woodrow's main 1928 building had its original windows restored and HVAC replaced, including new air exchangers in the auditorium courtyards.
 The first-floor restrooms were restored to the historic marble and wood and the second and third level facilities were gutted and replaced with modern fixtures.
 Electrical fixtures and computer lines throughout the campus were brought up to current standards.
 Drainage and landscaping improvements were also included in the construction, along with resurfacing of the parking lots and the Tim Brown-Davey O'Brien Track.

As of January 2013, the wing has been occupied by students; the official ribbon-cutting ceremony was held on March 23, 2013.

An addition, also with three stories, and a new gymnasium for athletic games are scheduled to be finished on June 27, 2019.
