Casa Gubern, known as the Condeminas Building, is one of the most notable buildings on Barcelona’s Passeig Colom. Listed as a BCIL heritage site, it is a Modernist building designed in the early 20th century. Over the years, its residences were converted into offices, resulting in the alteration and deterioration of the original decorative features. The project restored the building’s original residential use through high-end apartments.
The comprehensive refurbishment project involved highly complex structural reinforcement; the conservation and restoration of original elements of great artisanal value; the implementation of energy-efficiency strategies; and the functional adaptation of the building to its new uses.

- Integration of different reinforcement systems to improve the capacity of the original structure: encasing, shoring, propping, infilling…
- Implementation of advanced moisture-control systems and protection against xylophagous agents
The energy efficiency and sustainability of the building
- Energy refurbishment of the building envelope and replacement of HVAC and DHW systems to achieve an A-grade energy rating
- Maximum recovery of original heritage elements, minimising the need for new materials and reducing the building’s associated energy footprint
Restoration of high-value Modernist heritage elements
- Conservation and restoration of stained-glass windows, wrought-iron structures, Nolla hydraulic patterned tiles, handcrafted wooden ornamentation and decorative wrought-iron work
