25-Year Award

Recognizing buildings in Texas that exemplify the enduring value of good design.

Award Overview

Each year, the Texas Society of Architects 25-Year Award recognizes one building completed 25 to 50 years earlier that has stood the test of time by retaining its central form, character, and overall architectural integrity. This award is an important public outreach program that focuses much-deserved attention on distinguished Texas architecture of enduring significance and exemplifies the Society’s intrinsic message that “Good Design Matters.”

2020 Honoree

The 25-Year Award is awarded through TxA’s Honor Awards program. The 2020 recipients were announced on July 30. See the list of honorees.

2019 Recipient: Lucile Halsell Conservatory

The Lucile Halsell Conservatory at the San Antonio Botanical Garden was designed by Argentine architect Emilio Ambasz in partnership with Jones & Kell, now Muñoz & Company. It opened with great fanfare in 1988, its futuristic glass structures garnering several prestigious awards. With five separate conservatories linked with a central courtyard and buildings integrated into the landscape, the project revolutionized greenhouse design and continues to celebrate human connection to the plant world. The 25-Year Award was presented at TxA’s 2019 Conference in Galveston.
