Projects

A considered selection of works presented in context.

These pieces reflect Ache’s evolving material language and spiritual inquiry,  shown as they exist in space — framed, installed, and lived with. Each work is approached as an object of presence rather than image, emphasizing scale, texture, and atmosphere.

The onartium approach

Private access to contemporary work, guided by discretion, context, and care.

Viewings, acquisitions, and commissions are approached deliberately—with respect for the work, the artist, and its long-term placement in space.

Private Inquiry

good afternoon.

I'd like to view the work in person.

Is it currently available, and what is the asking range?

Confirmed.

A private viewing window and acquisition details will be shared.

Pricing, availability, and terms are shared following private inquiry.

"My work seeks to capture the invisible force that resides in matter. I paint as if color, gesture, and relief were ancestral languages that speak of what cannot be said."

About Onartium

ONARTIUM IS A PRIVATE STUDIO
DEDICATED TO THE CAREFUL
PRESENTATION OF CONTEMPORARY WORK.

We work between artist and collector, prioritizing
context, placement, and long-term stewardship
over visibility or scale.

Modes of Expression

A multidisciplinary body of work expressed across form, surface, and performance.

1

Painting

Ache’s primary practice, rooted in material exploration, relief, and spiritual symbolism. Works exist as objects of presence, scale, and texture.

2

Murals

Architectural works developed in dialogue with space, permanence, and public encounter.

3

Sculptural
Installations

DIMENSIONAL, SITE-SPECIFIC WORK—DESIGNED, BUILT, AND INSTALLED AS PART OF THE ARCHITECTURE.

4

Acting

Performance as narrative embodiment — exploring identity, tension, and transformation through film and character.
