GVFC Apartment is a refurbishment project carried out by Balzar Arquitectos contemplating the complete renovation of the apartment located in a building designed by the architect Antonio Escario, situated in one of the main avenues of the city of Valencia. The apartment occupies a corner position, characteristic for its chamfer that follows the configuration of the surrounding blocks. The organization of the interior has been a challenge for the architects as the geometry of the floor consists of different walls that are not perpendicular to each other.
As the name alludes, Sierra House adopted its nickname from its distinct roof profile. ‘Sierra’ meaning both ‘saw’ and ‘mountain range’ in Spanish. A fortunate coincidence as the house is located between Madrid’s north-westerly neighbourhoods of Mirasierra (look at mountain) and Montecarmelo (Mount Carmel).
