The Sanctuary at Camelback Mountain is in the final stages of development of its Spa House, a 3,500sq ft (312sq m), four-bedroom private mountain home dedicated to wellness and set to open in April 2016.

The Spa House, designed by Scottsdale, Arizona-based interior design firm Testani Design Troupe and Phoenix, Arizona-based architecture firm MoD A+P, features three king bedroom and one guestroom with two double beds; coupled with four new neighbouring casitas, the entire enclave will accommodate groups of up to 16, and can be used for retreats, special occasion getaways or executive corporate gatherings.

The Spa House includes a double treatment room for in-home massages as well as a movement studio for private classes or personal training with yoga mats, Pilates reformers, indoor cycling, free weights and other equipment.

Distinct spa-centric amenities will further enhance the wellness experience, including a Sanctuary Superpower minibar of specialty snacks such as raw nuts, organic dark chocolate and coconut water. Bathrooms will feature an assortment of aromatherapy bath salts.

In-room services will include a bedtime aromatherapy massage for hands and feet and delivery of a mindful colouring book. Bed-side tables will include custom journals to jot down reflections, and turndown service will include a card with a calming sentiment or balancing yoga pose suggestion. Room linens will be by Comfy.

Inspired by Sanctuary Spa’s Satori Wellness Retreats, a multi-day Spa House Satori programme can be customised for goals from mental and emotional wellbeing to physical development or restoration.

The Spa House will also include a Spa Concierge at the ready who can provide counsel and organise treatments both in-home and at the Sanctuary Spa, as well as a Sensei in Residence.

Guests will also have access to Sanctuary's 53-acre property, including the Sanctuary Spa, which features 12 indoor and outdoor treatment rooms as well as a Zen meditation garden and reflecting pond.

Specialised programming, such as sunrise yoga on the courtyard lawn, water aerobics in the private pool, professionally-led storytelling and astronomer-guided stargazing can also be arranged.
