After hanging up his boots, and his whistle, he designed the Sarrià Stadium in Barcelona for Espanyol in 1923.
[4] Born in Estella, Navarre, he moved to Barcelona to study architecture in 1902, at the age of 18, and he obtained his degree in 1910.
[3][4] He was a municipal architect in Haro (1912) and Estella (1913/23),[3] where he built Plaça de Braus (1917), the Bullring, the Peñaguda cross (he made the plans and the project of the cross while the realization was entrusted to a certain Mr. Cañete),[8] and designed a brilliant and necessary boulevard, still in the approval process a century later.
[4] This station was the only one of his kind in Navarra because Colmenares, an eclectic and worldly architect, designed it in a very unique modernist style with a strong influence of elegant Austrian secessionism, as if a little piece of Vienna had landed there.
[3] On 15 February 1937, in the middle of the Spanish Civil War, he was captured and arrested in Barcelona by a militia patrol during one of his construction visits and killed in the Cerdanyola del Vallès cemetery.
