Ombú is an Office Building project, located in the Andres Bello Avenue, at the Providencia District of Santiago, Chile.

Its name comes from a type of tree that grows in the surrounding parks, and expresses the privileged location, right by the riverside, the Sculpture Park, and the San Cristobal Hill.

Although surrounded by parks, this does not interfere with its commercial appeal. The building is only two block from the commercial axis represented by Alameda-Providencia-Apoquindo-Las Condes, one of the main streets of Santiago, and one of the most important commercial corridor in the country, and perhaps South America.

Characteristics of the Building

The building is thought as an small format office building, more efficient than his big scale neighbours. It is somehow a Boutique building, because of its accent on the quality and design of its spaces, rather than the scale.

It comprises 10 stories, with a ground floor of 625 sq.m a first floor of 380 sq.m, 456 sq.m in the second floor, 410 sq.m from the third to eighth floor, and 382 sq.m on the ninth floor.

It has a total of 4.306 sq.m over ground; of which only 10,7 % (462 sq.m) represent common space, leaving a total of 3.843 sq.m of office area.

The building is organized in rectangular plans, with its longer side on the east-west orientation, facing the park, the river and the San Cristobal Hill. This delivers a great visual amplitude, and a great predominant north orientation. The structure is composed by post tensed slabs, which allows a higher interior height and fewer columns, which gives an important interior flexibility.

To solve the sunlight exposure, the building considers a series of screen printed glass fins that protect the offices from the sunset light, but allowing panoramic views.

The façade as a chandelier gives the building a light, contemporary and original look.

At night, the lights of the façade, along with the glass fins, will transform the building in a sort of lighthouse  that will stand out of the river skyline.

Underground the building contemplates five levels for parking, with a total of 2.655 sq.m and 108 parking spaces.

In the Providencia neighbourhood, right on Andres Bello Avenue, between Andres de Fuenzalida and Las Urbinas streets, the building faces north, delivering wide views over the Mapocho river, the park that runs along it, and the San Cristobal  hill.

The building was designed be used as office space, and it comprises a vanguard expression, with an attractive play of volumes which comes as a result of an accurate study of the regulations regarding the site.

The tectonic expression seeks to create a contrast between the noble expression of the concrete and the technological look of the black aluminium ventilated façade.

The north and east facades are conformed by a series of screen printed glass sunshades, which are placed transversally to the curtain wall, as a way of reducing the effects of the sun. On the other side, the south façade is regularly perforated, and the west side of the building is completely closed, to avoid the high temperatures of this orientation.

Comprising 10 stories and 5 underground parking floors, the building offers space for three offices per floor, between 90 and 130 square meters. Its name (Ombú) comes from the type of tree that grows right in front of the site, by the riverside.
