The Huartes also asked Antonio Bonet Castellana to design the initial urban development project in La Manga del Mar Menor and also commissioned Coderch to design the Hotel del Mar in Palma de Mallorca, or Juan Daniel Fullaondo to design the Restaurant Ciudad Blanca in Alcudia.
Jesús Huarte initially lived in an apartment in the Huarte building in La Castellana, owned by Felipe Heredero, renovated by Vázquez Molezún and decorated by Francisco Capuleto, and in 1966 commissioned his house to the architects Corrales and Molezún, a brilliant example of a modern home, built in Puerta de Hierro. Examples that he constantly applied to himself, such as the commission in Mallorca of his garden to the Uruguayan Leandro Silva.
Commissions that his brothers also carried out: María Josefa Huarte called on Fernando Higueras for her house in Somosaguas (although it was not built), Fernando Redón was commissioned for Felipe Huarte's houses in Pamplona and in La Manga del Mar Menor and Sáenz de Oíza for Juan Huarte's house in Pollensa.
He implemented innovative construction methods, such as prestressed concrete, which was used to build works such as the Alloz aqueduct by the engineer Eduardo Torroja, or he was responsible for the construction of the Recoletos Frontón in Madrid, a project by Secundino Zuazo and Eduardo Torroja. He experimented with the development of patents for some prefabricated concrete houses or load-bearing plaster partitions, among others.
He had musical studies thanks to his father's passion for music, which led him to preside over the Orfeón de Pamplona, create the Chair of Gregorian Chant at the Pamplona conservatory or found the Alea group, a musical research centre, in 1963.
Author of the meetings in Pamplona, to which in 2009 the Reina Sofia Museum decided to host a monographic exhibition where the famous pneumatic domes of José Manuel de Prada Poole were presented.
He was a passionate collector of contemporary art and, together with his brother Juan (he did not like to be considered a patron), he sponsored musicians and artists such as Oteiza, Chillida, Palazuelo, Basterrechea or Ferreira and painters such as Tapies, Antonio López, Millares, Rivera, Lucio Muñoz, Cossío or Vaquero Turcios. And in different ways, such as supporting Camilo José Cela for the magazine Papeles de Son Armadans (where dialogue with Spanish exiles was promoted), and with whom they would found the publishing house Alfaguara.
The Huartes also promoted industrial design with the company H Muebles, focused on interior design, industrialisation and modern furniture design, with two shops in Madrid, the first in 1961 at Calle Alberto Aguilera 61, with the project by Molezún and José Luis Aranguren and the second designed by Fullaondo in 1965. Through competitions they produced furniture for Jesús de la Sota, Rafael Moneo, Vicente Gregorio and Miguel Milá.
Finally, an immense legacy without which the second half of the 20th century in Spain would not be understood.
