3A Interior Design

Services · Interior Design

From the starting point to the installed room

The studio holds the full lifecycle of a project under one roof — from the first conversation to the final piece of art on the wall. Below, the way we work.

The Process

  1. 01

    Starting Point

    A private conversation in the studio or on site. We listen, walk the rooms, and define the scope, programme and ambition of the project.

  2. 02

    Conceptualization

    A bound concept document — references, palettes, mood and a single clear creative direction agreed before any drawings are produced.

  3. 03

    Planning

    Full construction drawings, lighting plans, joinery sections and a coordinated set of details — issued to engineers, contractors and craftsmen.

  4. 04

    Custom Design

    Bespoke furniture, joinery and built-ins designed in-house and produced with a small circle of European workshops we have known for years.

  5. 05

    Installation

    The studio installs and styles every room. Handover is the day the residence is finished — not the day works conclude on site.

Furniture & Joinery

Storage, wardrobes and freestanding pieces conceived with the same rigor as the room itself

We aim for presence without noise: proportions tuned to the architecture, surfaces with depth, and details that feel deliberate even in silence.

Curated Makers

3A works with the finest furniture and interior makers in Europe

From Baxter, Minotti, Molteni&C and Poliform to small Italian and German ateliers, every piece is selected — or specified bespoke — to sit in quiet dialogue with the architecture of the room.
