Fundació Miró Mallorca brings back Son Boter and its graffiti

Thirty per cent done, the delicate part behind it

The works began in October 2025 under a contract of fourteen months. Eight months later, by the Fundació's account, around 30 per cent had been completed. The most delicate stages were already finished: the protection, study and recovery of the historic graffiti that make Son Boter unique in the cultural heritage of Mallorca, carried out under the permanent supervision of a specialist conservation team after a long phase of analysis and documentation. Traces and graffiti by the artist that had been lost are being recovered.

Alongside the building work, the house is monitored scientifically. Regular salinity tests and environmental measurements in the rooms show how the materials behave, so that the historic surfaces stay safe while the builders are at work.

From the roof downwards

With the drawings protected, the focus moved to the structure. The roof has been consolidated, waterproofed and insulated, while its characteristic elements are restored and given their final finish. Inside, the work runs from top to bottom: the attic floors are being reinforced, beams on the first floor are selectively replaced and strengthened, and on the ground floor carbon fibre reinforcement secures the structure while keeping the original elements in place. In June the Fundació expected the building to be fully consolidated within weeks.

The restoration has also reached the former printmaking workshop, where the wall surfaces are being repaired, obsolete installations removed and the remaining infrastructure checked. Outside, the traditional paving of river stones has been lifted for the works and will be laid again at the end, and studies of the perimeter walls prepare the cleaning and restoration of the façades, which should give the house back its historic appearance.

Why Son Boter matters

For the Fundació, Son Boter is one of the places most closely linked to the creative world of Joan Miró, and its restoration is part of a wider strategy for conserving the architectural heritage in its care. For visitors it is the more intimate counterpart to the galleries: walls on which the artist drew directly, now being stabilised line by line. The Fundació is in Palma, at Carrer de Saridakis 29, and our guide to artists and writers on Mallorca places Miró among the other names who made the island their workplace.

The figures behind the scaffolding

The construction budget is 833,000 euros plus VAT, and by June 2026 certified spending stood at 234,830.68 euros. The building works are carried out by VESTA, project management lies with Anna Ibarz, Joan Fortuny and Joan Muñoz, and the conservator-restorers are Marina Granero and Zaira Bordoy. Whether Son Boter reopens in December depends on the remaining phases; current dates and opening times are published by the Fundació Miró Mallorca.
