Two Treanor Projects Recognized by Preservation Dallas

Two Treanor projects have received 2026 Preservation Dallas awards, recognizing work that helps significant places continue to tell their stories.

The Henry Etta Robinson Eidt House received the Spirit of Preservation Award in the special recognition and honor awards category, while the Terminal Annex Federal Building received a Preservation Achievement Award in the commercial category.

Preservation Dallas’ Preservation Achievement Awards recognize projects and people contributing to the preservation, rehabilitation, and continued stewardship of historic buildings and neighborhoods throughout the Dallas area.

For Treanor’s Historic Preservation team, the two projects represent very different places and scales of preservation. One is a 1906 Queen Anne cottage shaped by its owners’ personal connection to their neighborhood. The other is a monumental federal building at the edge of Dealey Plaza. Both called for a careful understanding of existing character, materials, and history.

Terminal Annex Federal Building

Originally known as the United States Parcel Post Building, the Terminal Annex was constructed in 1937 as a New Deal public works project. Its simplified Art Deco design is defined by stylized stone panels, strong vertical elements, granite, limestone, brick, and metal windows. Two additional floors were completed in 1940.

The building occupies a prominent site on the southern edge of Dealey Plaza and has longstanding connections to the history of Dallas.

Treanor’s work began with a 2019 Building Preservation Plan for the U.S. General Services Administration. That work informed an exterior restoration project focused on retaining and repairing historic materials wherever practical.

The project scope included cleaning the granite water table, fluted granite pilasters, carved granite spandrels, limestone, and historic brick. Areas of deteriorated limestone were repaired using patching material customized to match the surrounding stone. Mortar analysis guided repointing so that new mortar would be compatible with the historic masonry in appearance and strength.

The building’s original steel double-hung metal windows were repaired, resealed, and repainted. The team also addressed moisture-related deterioration at the rear entrance portico and reconstructed modern brick site walls with new flashing and matching brick.

Completed in February 2025, the work renewed the building envelope while retaining the materials and architectural features that give the Terminal Annex its distinctive presence.

Henry Etta Eidt House

Built in 1906, the Henry Etta Robinson Eidt House is a Queen Anne cottage Victorian in Peak’s Suburban neighborhood. Owners Mike Grable and Ben Garner approached the restoration with a personal connection to the neighborhood and a desire to maintain the historic home while modernizing it for the comforts of today.  Grable’s grandmother spent her early life in the neighborhood, and her father and grandfather were leading Dallas architects.

Treanor had a limited role, assisting with assessment of the original wood features, including the historic wood and window survey and Landmark Commission approval. The work included identification of finish carpentry repairs and original wood window restoration. A new compatible porch railing was added. The project received Preservation Dallas’ Spirit of Preservation Award.

Preservation at every scale

The Henry Etta Eidt House and Terminal Annex Federal Building could hardly be more different in size, use, and character. What connects them is Treanor’s passion of our Historic Preservation team, required to understand what should remain, what needs repair, and how thoughtful interventions can support the next chapter of a historic place.

We are grateful to Preservation Dallas for recognizing both projects.  Our clients for the Terminal Annex include the U.S. General Services Administration with HED Architects, Hammer Construction and Frontier Waterproofing.  We are thankful to Mike Grable and Ben Garner for adding us to their team for the Henry Etta Robinson Eidt House.
