Ariane Mostert, architect and founder
As an architect, I have spent many years working across architecture, interior architecture, and interior design. Through roomseventeen, I create considered spaces shaped by context, material, and the people who inhabit them.
01
Ariane remains personally involved from the first conversation through final handover.
02
Residential and commercial work across Europe, the Middle East and beyond.
03
Architecture, interiors, FF&E, project delivery and construction supervision under one direction.
Rooted in context,
open to the world
Every project starts with its particular setting: the architecture already present, the quality of light, the surrounding landscape and the way people will use the space.
Working from Frankfurt across Europe and the Middle East, roomseventeen brings an international perspective without losing sight of local materials, makers and building culture.
A close network of consultants, specialists and craftspeople is assembled around each commission, with Ariane providing one consistent design direction from concept to completion.
