About

OABYH is the artistic moniker and sculptural practice of Portuguese visual artist Helder Fernandes. Exploring the balance between digital processes and manual experimentation, the artist works at the discipline‑blurring intersection of geometric abstraction, architectural form, and industrial material experimentation. 

Helder’s artistic practice centers around the transformation of medium-density wood fiberboard (MDF). By developing specialized, proprietary studio techniques to patinate, dye, and texture this engineered wood composite, the artist elevates an industrial material into an expressive medium for high-end art. His work — ranging from deep-relief wall structures to free-standing dimensional objects — challenges the traditional perception of material, transforming rigid geometry into tactile, timeless art pieces.

Every single object is independently developed through an uncompromising "Studio Practice" — conceived, prototyped, and individually handcrafted to order by the artist himself. Embracing a deep commitment to environmental consciousness, OABYH focuses on sustainability by utilizing high-quality wood composites made from industrial wood processing by-products and sawdust, turning reclaimed resources into refined, quiet luxury.

Characterized by clean mathematical lines, a meticulous study of depth, and specialized ultra-matte finishes that dramatically capture shifting ambient shadows, OABYH's work is sought after globally by contemporary architects, interior designers, and private collectors.

FAQ

Are your pieces produced in limited editions?

My work is created in open series. I produce new units only while I take genuine pleasure in making it. There is no fixed edition size, and production may continue or end according to my creative rhythm.

Often, I create unique pieces — singularities born from layers of experimentation or made from reclaimed wood that’s decades old. Sometimes I come across a fragment with forty years of history, just enough to create a single unit. Once it’s gone, it’s gone. 

What kind of materials do you use?

I mostly work with wood composite (MDF) and reclaimed wood — pieces salvaged from broken furniture or discarded materials. These fragments carry stories and character that new wood simply can’t replicate. Collecting and repurposing them is part of my creative process, and often, it’s enough to keep me going.

Occasionally, I do need to purchase wood to meet specific design or production needs. When I do, I choose responsibly sourced materials that align with my commitment to sustainability and quality.

Why do you use MDF as one of your main materials?

When treated with care and finished using my own techniques, MDF becomes an expressive and versatile material — capable of capturing the precision, texture, and emotion I seek in each piece. MDF consistency make it ideal for the kind of thoughtful design I pursue. It enables me to replicate each piece with high quality while still allowing space for individuality in the finishing process.

Using MDF is also part of my commitment to sustainability - Medium Density Fibreboard (MDF) is a wood by‑product — solid panels made from sawdust of the wood‑processing industry. By choosing MDF, I’m able to transform what might be discarded, into something meaningful and enduring.

Do you accept commissions and/or collaborate with art stores, galleries, or design studios? 

Yes. I accept commissions and collaborate with selected art stores, galleries, and design studios whose curatorial vision aligns with the sculptural identity of OABYH. Partnerships may include exclusive pieces, curated open‑series selections, or custom‑developed works tailored to a specific space or collection.

I prioritize collaborations that value craftsmanship, material experimentation, and long‑term artistic integrity. If you represent a store, gallery, or studio and wish to explore a partnership, please share information about your curatorial approach and the type of work you are looking for.

How should I care for my object?

To preserve its beauty, simply dust gently with a soft cloth and avoid prolonged exposure to moisture or direct sunlight.
That said, each object is unique and may require specific care depending on its materials and finish. If you’re unsure, feel free to contact me — I’ll be happy to advise you on how to best care for your piece.
