[1] Built between 1955 and 1958, it was designed as a mixed use building for apartments and offices for the headquarters of the National Medical Insurance Company by Antonio Quintana Simonetti.

At the national level, Quintana received the recognition of the main specialized publications that circulated in the country at that time: Architecture, Space, Cuba Album, etc .

Almost at the end of the 50s, he receives two distinctions: in 1959 the Gold Medal Award of the National College of Architects and the condition of best commercial work of this period.

[6] The only complete package of information about the building is the slides that were presented for the architectural contest, collected in the magazine 'Arquitectura', nº 269, of 1955 published by the College of Architects of Havana.

Because of the high cost of the site, the project was increased by the need to add rental income from apartments that would help to make the building profitable.

Quintana established a visual dialogue between the two geometries and generated new guidelines for the new emerging modernist, mixed-use typologies in Havana.

[b][4] The Seguro Medico was a private company, they were the landlord and owner of the residential tower and thus subject to the new property redistribution instituted by the Castro government.

Similar to the Lever House in Manhattan, Antonio Quintana Simonetti (1919–1943) sets up a relationship of two volumes of dissimilar proportion: a box at the lower level containing the Seguro Médico offices, and an eighteen-story residential block.

Similar to the FOCSA Building's podium used only for recreation, the residences are located over the roof of the Seguro Medico offices; a large plane made into a children's playground (garden) as shown in the Quintana sketch-drawing for that area.

They divide the apartments and rooms and are unpainted, set in common, gray mortar, the wall sits on top of a black 152 millimetres (6.0 in) terrazzo baseboard that matches the floors.

The wall enclosing the vestibule in front of the elevators is made of an aluminum frame for glass panel inserts with operable windows.

One, accommodates a horizontal operable window in the middle of the wall, (similar to the FOCSA Building), which is made up of two prefab concrete slabs.

The Edificio del Seguro Médico was awarded First Prize at the Architecture Competition in 1954 and a Gold Medal by the School of Architects in Havana in 1959.

[4] The parti [e][f] of the site's area distribution of the Edificio del Seguro Médico is similar to that of the FOCSA Building and the 1952 Lever House on Manhattan's Park Avenue.

The site distribution and parti is also similar to the proposed project that was to replace the Plaza del Vapor, designed in 1959 by the architect Carlos Alfonso for the National Institute of Savings and Housing under Pastorita Núñez.
