A NEW LANGUAGE OF FORM FOR MODERN PETS
ELEVATED PET DESIGN, CRAFTED IN FRANCE.
The One Off® is a Paris-based design brand and studio specialising in sculptural objects for cats and dogs.
Founded by designer Diane B. de La Serve, the brand merges minimalist aesthetics, behavioural insight, and French artisanal craftsmanship.
Each piece is designed to meet essential animal needs — verticality, comfort, security — while integrating seamlessly into refined interiors.
Blending noble materials such as wood, metal, leather, and wool with instinctive function, The One Off® imagines a shared interior language: durable, intentional, and deeply caring.
“The One Off redefines the relationship between form and function, crafting objects that transcend their purpose”
Diane B. de La Serve
OBJET SCULPTURE: FUNCTIONAL OBJECTS, SCULPTURAL PRESENCE.
Designed to coexist with art, architecture and instinct, The One Off® pieces respond to the natural needs of cats and dogs while standing as visual statements in their own right.
The iconic 4 Steps to Heaven — a modular, wall-mounted cat ladder — and the Lust cushion — a layered rest system inspired by high-end upholstery — are made for climbing, perching, scratching or resting.
Crafted in metal, leather, wood and textile, each object is handmade in France and built to last.
All creations are tested by the founder’s own companions, who help shape both the form and the spirit of the collection.
The One Off® redefines how animals inhabit space.
This is more than pet furniture — it’s a philosophy of coexistence, and an art of living with our animals, with grace and intention.
A NEW PHILOSOPHY OF LUXURY PET DESIGN.
Rooted in Paris and driven by a bold, anti-conformist spirit, The One Off® reimagines pet objects through the lens of art, design and behavioural insight. Each piece is the result of a carefully orchestrated artistic process — inspired by minimalist sculptors and American visual artists like Carl André, Cy Twombly or Jackson Pollock.
Guided by a trained eye and a deep affection for animals, Diane B. de La Serve imagines objects that are both sculptural and functional — designed not only to blend into elegant interiors, but to satisfy the physical and emotional instincts of our companions.
Tested at home, refined through use, and made to last, each creation seeks to become an object of desire — for aesthetes who value care, craft and conceptual clarity.
4 STEPS TO HEAVEN: A STATEMENT PIECE.
4 Steps to Heaven redefines the cat tree: an architectural form that respects your cat’s instincts — and your aesthetic standards.
Climb, perch, scratch, or rest — without compromising your interior.
This modular wall-mounted piece is handcrafted in brass or aluminium, and finished with leather — customisable, timeless, feline-approved.
HEIGHT IS NOT A LUXURY. IT’S A NEED.
In the wild, cats climb to feel safe, to watch, to rest above the world. Indoors, this behaviour remains — but their environment rarely follows.
The One Off® offers sculptural alternatives that respect your cat’s nature while elevating your space.
Verticality is not a luxury. It’s a form of care.
