Delfín Tower, Residential skyscraper in Poniente Beach, Benidorm, Spain

Delfín Tower is a residential building at Poniente Beach in Benidorm with 23 floors and about 44 apartments designed for comfortable living. The structure features floor-to-ceiling windows that flood each space with natural daylight throughout the day.

The plot was carved out of the land of the Gran Hotel Delfín, with the segregation licence granted by Benidorm's town hall in mid-July 2017. Site preparation and earthworks began in January 2018, and work was paused in July and August to respect municipal rules during the tourist high season. Construction finished in July 2022.

The tower stands on part of the plot of the Gran Hotel Delfín, and its name keeps that of the earlier hotel. Its sail-shaped silhouette is the feature residents and passers-by single out. The 16th floor, a single 350 m² apartment, sold on 6 January 2018 for 2.08 million euros, the highest price paid for a flat in Benidorm's history.

The tower stands on the beachfront plot once occupied by the Gran Hotel Delfín, so the seafront is reached on foot from the building. The two upper floors are joined to house a social club, gym and indoor pool, while the grounds hold a paddle court and a salt-chlorinated infinity pool. The gardens use native plants with very low water needs.

The rear facade has two layers: an outer micro-perforated bioclimatic textile membrane coated with Teflon, set 10 cm from the terraces, which reflects heat and releases it through upper openings and can be moved electronically. The southwest-facing glazing carries photovoltaic panels.
