Black-box renovation in Barcelona

Reliable rough base that supports the whole project without hidden defects

Why black-box quality defines final outcome

Black-box stage is the technical foundation of the entire renovation. Mistakes here inevitably surface later as cracks, geometry conflicts, engineering issues and expensive rework.

In Barcelona, with older building stock and uneven structures, careful diagnostics and staged control are essential before finish works begin.

What is included

  • Site preparation, protection and debris handling.
  • Demolition of obsolete layers and structures.
  • Rough geometry alignment of walls, floors and ceilings.
  • Engineering routing: electrical, plumbing, sewage and embedded elements.
  • Technical zone preparation for built-ins.
  • Intermediate quality checks before next phase.

Project stages

Stage 1. Diagnostics and technical preparation.

Stage 2. Demolition and contour clearing.

Stage 3. Engineering and structural rough works.

Stage 4. Control checks and handover to finish stage.
