US-based design studio SALT + BONES have completed a wellness renovation of The Casa Madrona Hotel and Spa in Sausalito, California.

The overhaul, which – the architects said – was inspired both by the sea and by "the materials of luxury yachts" – saw the creation of a lobby, courtyard, and nine wellness guest rooms, as well as a three-treatment-room spa.

A fitness suite will also be added to the Casa Madrona's facilities in spring 2019.

The hotel's other newly introduced wellbeing offerings include nine "sleep smart beds" with temperature regulation and biometric tracking features; Muse 2, a brain-sensing headband that guides meditation and monitors brain activity; and Vi Sense, a virtual personal trainer that dictates customised coaching advice through heart-rate sensing earphones.

The redesign is the second for Casa Madrona in the last seven years following its acquisition by MetWest Terra Hospitality in 2010.

In 2014, Safdie Rabines Architects completed work on the property's initial refurbishment, transforming the resort's three-storey William G. Barrett House – a nationally registered historic Victorian mansion – into 11 luxury guest rooms.
