Two designers, one drawing.
Roarch was born in Porto Alegre and brings together two generations of design: twenty years of workbench, factory and site on one side, and a fresh, detail-minded eye on the other.
Rosana started out drawing refrigeration equipment and moved through fitted furniture before designing entire stores. At every stage she learned the same lesson: a beautiful project must first work for whoever works in it.
Ana Maria grew up among drawing boards and joinery catalogues and graduated in Interior Design. She brings the residential eye, 3D modelling and the eagerness to learn on site.
Together they founded Roarch so that one's experience and the other's curiosity meet in the same drawing, from the first sketch to the installation.
What we believe in.
- 01
Measure before form
Every drawing begins with a measurement and a real routine. Form comes later, as a consequence of what the space has to do.
- 02
Honest materials
Wood that looks like wood, glass you can see through, stainless steel that survives daily use. Finish is a design decision, not decoration.
- 03
Followed to the site
A drawing is only finished when the space is handed over. That is why we follow the factory and the installation, not just the drawing board.
