01 / The studio

An elegant resonance between art and space.

4Y is a high-end interior design studio spanning the East and West Coasts. Under the Maison & Aura signature, we create spaces with a sense of place, a clear point of view and a deeply personal connection to the people who inhabit them.

In Los Angeles, our focus is on creative offices and immersive brand environments. In Miami, we compose high-end apartments and private villas where French romanticism meets the ease of contemporary coastal living.

Our approach begins with listening. We balance symmetry, proportion and exquisite craftsmanship with open layouts, purposeful functionality and a carefully edited collection of materials, furnishings and art.

Classical spirit. Contemporary life.

Before we begin

A few useful details.

What should I bring to the first consultation?

A few inspiration images, your location, approximate floor plans if available, and a sense of your budget and timeline. We can help clarify the brief even if you are at an early stage.

Can you combine classic and contemporary styles?

Yes. This dialogue is central to our approach: classical proportions and handcrafted details provide the foundation, while contemporary furniture, lighting and layouts keep the space comfortable and relevant.

Do you offer furniture and art consultancy?

Our bespoke service can include furniture, fixtures and equipment, decorative finishes, styling and art consultancy. The scope is shaped around your project during the consultation.

How is a project scope established?

We start with your goals and the existing space, then discuss the level of design development, selections and execution support required. Deliverables and coordination responsibilities are agreed before work begins.
