Onn Hair Salon | Spicy Architects + swarm Inc.
Onn Hair Salon is nestled within a tenant building in Daikanyama―an area renowned as a creative hub for salons. It occupies a unit where the owner of the building previously resided. Upon entry, guests are greeted by a calm, welcoming waiting area. The cutting space beyond feels both playful and sophisticated, much like the atmosphere of a photo studio.
Our design philosophy stemmed from the belief that furniture and object arrangements are a powerful form of personal expression. We aimed to create a space where these elements are not just present, but a space that elevates and integrates them seamlessly into its story.
To accommodate the client’s request for hand-selecting decorative details, we conceived the interior as a blank canvas, all while retaining some key features of traditional Japanese housing. The subtle textures of the stucco-finished walls and ceiling, alongside the delicate pattern of the linoleum floor, form a nuanced backdrop, allowing the client’s diverse collection of objects to harmonize effortlessly with the surrounding architecture.
The alcove, originally a tokonoma―a traditional Japanese display space―was preserved; now, any piece placed within it becomes both unassuming and distinctly noticeable. Finally, the garden view, reflected through the salon’s mirror, creates an unexpected depth, culminating in a truly unique and dynamic backdrop tailored to the client’s aesthetic.
