03 — Process

The need for time in making by hand.

Some things can't be rushed. Working with wood takes time to observe, experiment, test a solution, cut a joint, adjust and, when needed, change course. It's in this direct contact with the material that many decisions emerge: much of what gives a piece its quality happens precisely in this time of making.

01

Conversation

Understanding the use, the space and the intention of the piece, and assessing feasibility.

02

Wood

Choosing the species, grain pattern and finish.

03

Drawing

Technical drawings, joinery studies and a prototype when the project calls for one.

04

Making

Planning, defining and carrying out the construction processes.

05

Delivery

Management of shipping and hoisting (if needed), provided as a separate service by a subcontracted company.

04 — The studio

Rafael Silva,
designer and woodworker.

My story with design and woodworking began in 2009, in my grandfather's handcrafted furniture shop, where I worked while studying Design. That's where I learned to listen carefully to clients and turn their ideas into unique pieces.

Today I divide my time between creating original designs, developing prototypes, small-batch production and technical consulting for private clients, companies, architects and designers.
