High efficiency HVAC and DHW production for the refurbishment of the Hotel Las Casas de El Arenal in Seville

The four-star hotel Las Casas de El Arenal, situated in a refurbished 19th century building, is less than 10 minutes from the doors of Seville Cathedral and the Giralda tower. Decorated with close attention to detail, it has preserved the building’s high original ceilings. This hotel has recently been refurbished with the participation of CM4 Arquitectos as project managers, with Otaisa appointed as works supervisor. For the temperature control and domestic hot water production, units from Japanese brand Mitsubishi Heavy Industries were selected.

This project set out to give a new use to two 18th century Seville courtyard houses by refurbishing their structure and installations while respecting their inherent characteristics: the façades, patios and galleries as well as the relationship between floors and the original facing. The result is a hotel that has been effortlessly housed within a historic building, with no need to introduce elements that alter the original architecture.


The hotel Las Casas de El Arenal has 27 bedrooms distributed over three floors, fitted into the original spaces provided the dimensions and stability of the building so permitted. The bedrooms have coffered wood ceilings made using traditional timber framing methods. Restoration work was also carried out on the stairs, which feature Italian marble steps and elegant wrought iron and wood banisters. Read more…
