The project consists of the interior renovation of a commercial premises Located on the ground floor and mezzanine of an existing residential building, at 9 Arrasate Street, in Donostia-San Sebastián. The work is carried out entirely within the premises, without affecting the load-bearing structure or the building envelope.

The intervention begins with a pre-existing condition that included interior partitions, suspended ceilings, finishes, and installations associated with a previous commercial use. The scope of the project includes the complete demolition of the existing interior layout, including lightweight partitions, false ceilings, cladding, joinery and installations, with the aim of leave the space completely clear, clean and prepared for future implementation and use.

The premises have a rectangular layout distributed over two levels, with an approximate usable area of 545 m² on the ground floor and 675 m² on the mezzanine, allowing for great flexibility of use and adaptation to different functional programs. The intervention facilitates a clear understanding of the existing structure and enables a precise survey of the building's current state for subsequent project phases.

The works are limited to controlled interior demolition, respecting the building's structural elements and ensuring the stability, safety, and protection of adjacent spaces. The project also incorporates a specific study of waste management, establishing criteria for separation, removal and final disposal of construction and demolition waste in accordance with current regulations.

The project justifies compliance with municipal urban planning regulations, as well as the applicable basic requirements of the Technical Building Code, particularly regarding structural safety and fire safety, consistent with the limited scope of the intervention.

The result is a open, versatile and technically prepared commercial space, which forms the basis for a future comprehensive reform and adaptation to a new use, fully integrated into the urban and building context of the surroundings.
