The Casa Oller is a Modernist building cataloged, designed by Pau Salvat i Espasa, and its the result of an intervention on a pre-existing building that changed its access from front to side to be able to access a carriage, maintaining the core of stairs, opened a central patio, with the private access stairs to the main floor, as were common in the large Gothic and Modernist estates of Paseo de Gracia (it is worth remembering that in the “rental houses”, the Land Lord who built normally lived in the main floor – hence its name -, the rest of the plants are dedicated to rent. In order not to lose square meters, he built a new cradle, behind, which means that we have two walls of 40 cm in parallel (because the interior wall, in its day, was the rear facade), and later the gallery was added. Casa Oller does not exhaust the square meters that is granted by the regulations and could build a sixth floor, under the conditions established by the Ordinance.
After a failed attempt to rehabilitate the building as corporate offices and business center, the project now seeks to rehabilitate the ancient homes that were in its day and turn them into luxury apartments, allocating the basement into equipment of the inhabitants (social club, spa, gym, etc.) and roof terrace as a solarium and community pool.
