Zwolle, The Netherlands
Interior design firm Concrete has created a massage boutique in Zwolle, that invites everyone to leave the outer world behind, and recharge in a natural and harmonious environment.

Concrete is responsible for the whole project, interiors, identity, and the name of the massage boutique “Oikoa”.
The brand name is derived from the Finnish word for ‘smooth correction,’ providing an introverted realm of calm after a treatment which untangles the body making feel almost ‘liquid’.
This massage venture is designed as a serene space where guests can focus on their inner self and wellbeing.

This was achieved by turning the existing extroverted glass cube inside out and placing the organic-shaped central space at the heart of the building, with the treatment rooms situated on the perimeter.
Guests enter directly into the core of the boutique; a warm introspective space lined with multiple curved walls, finished in warm oak laths.

The curved walls create intimate seating areas, with softly curved benches upholstered in moss green velvet. These are the perfect spots to wait in full comfort and prepare for treatment.


This feeling is reflected in the logo: a liquid oil drop combined with a minimalistic but elegant font.

Bright white backdrops and pine green emphasize the natural and harmonious environment of the massage salon, which is further enhanced by a secondary color family of oil drops.
Both the oils and colors are derived from Finnish natural elements such as ferns, aspen trees, cloudberries, and bellflowers.
