"We were very conscious of how we illuminated each of the different surfaces and how light could help emphasise the natural characteristics of materials", the studio told Dezeen.
Overall the studio aimed to meet spa lighting guidelines while maintaining a calm and peaceful atmosphere in the space.
As the Sensasia Stories Spa is located in a busy mall, the lighting designers wanted the entrance space and reception area to act as a calm area of transition from retail to spa environment.
The 270-square-metre spa contains eight treatment rooms, along with an ice fountain, herb saunas, steam rooms, and pool, that are arranged around a central courtyard.
In this central space interiors studio Roar and Studio N created a large arched structure that contains illuminated arches. "We used linear grazers to pick out the texture of stone walls," said Studio N.
Strip lights were integrated into the pool's stairs and, in other areas, smaller lights and decorative light fixtures were used to create illuminated accent walls.
A recessed gobo projector was used to replicate the movement of water, which the studio said was "a subtle reference to the natural world".
The studio used recessed wide-beam pinhole downlights to provide general lighting to the space in a minimal style.
The lighting of each area of the spa can be controlled via a DALI lighting control system which allows lighting to be changed between lighting scenes. Treatment rooms can be changed between 'mood lighting', 'treatment' and 'cleaning scenes'.
Studio N is shortlisted in the architectural lighting design category at the Dezeen awards 2022 alongside Liftshutz Davidson Sandiland and Leo Villareal's Illuminated River installation and a theatre venue clad in luminous tiles in China, by Brandston Partnership.
