From 1911 to 1918, Wiechers was commissioned with various important buildings in Ponce, such as the Logia Aurora, Club Deportivo de Damas, the Teatro Habana, Banco of Ponce building, and Santo Asilo de Damas Hospital among others, where he fully expressed the European Neo-Classical style which he had learned from European training.

[2] In 1919, feeling political persecution from the American invaders, Mr. Wiechers sold the house to Mr. Gabriel Villaronga and moved to his native France.

In the early 1990s, and in order to establish the Museo de la Arquitectura Ponceña, the house was acquired and restored by the Institute of Puerto Rican Culture (ICP).

The museum possesses elaborate neoclassical details, a majestic roof-top gazebo, and a full set of original and custom-made Catalan modernist furniture.

Each bay contains a wooden movable louvreed window with glass inlets at its top, and a floral relief motif over the fenestration.

Another interesting feature of the house are the balconies which are divided into three sections with Ionic columns and framed with Baroque moldings and sculptured faces on the central top part of the openings.

[2] Some of the outstanding architectural features present in this museum are highly decorative and detailed pilasters, rusticated podium, cornices, "candelabra", relief and motifs, Ionic capitols, etc.

Other interesting details on the house are: the bathroom fixtures, such as the shower stall and the ceramic wall tiles which were imported from Barcelona, Spain, the light fixtures—such as the ones at the dining-room, the master bedroom and living room—which were also imported from Spain, and a "medio punto" at the dining area, typical of the architecture of this Southern area of Puerto Rico.

[2] The museum has an extensive collection of displays and photos of master works from the most prominent architects of early 20th century Ponce: Blas Silva Boucher, Francisco Porrata Doria, Alfredo Wiechers Pieretti.

[11] The city of Ponce, considered by some as the "irrefutable guardian of Puerto Rican criollismo",[12] was selected as a member of the prestigious Art Nouveau Route of the European Union for its "world preservation of modernist heritage".
