Every space tells a story. We help you find it.

We are inspired by challenges and by the possibilities within every space. We can turn something large into something warm and inviting, and make the small feel practical and open. It’s about understanding space, materials and time — and about seamless collaboration and genuine empathy for our clients.

Protest Design is an award-winning interior architecture studio where creative thinking meets long-standing experience. We design workplaces, customer environments and homes in both new and existing buildings — always beginning with the needs of the people who use them.

We design the small and the large.

Sometimes a short, intensive design sprint is all that’s needed; other times the work continues through several phases and over many years. We adapt our approach to the rhythm and goals of each project and take care of the practical side of the design process. Get in touch — and we’ll find the right way forward together.

Interior design

We help our clients create spaces where work flows smoothly and people feel well – workplaces, customer environments and homes that feel personal, function effortlessly in everyday life and offer meaningful, memorable experiences. Our design combines artistic vision with architectural understanding and strong technical expertise.

Workplace design & Spatial Brand Identity

We design workplaces that support wellbeing, help work flow smoothly and express your company’s identity with clarity and purpose. Our solutions evolve with changing needs, combining insight into how people use space with a strong understanding of functionality, flexibility and sustainable materials.

Human-Centered Design

We approach design from the users’ perspective, creating spaces that are clear, functional and pleasant to experience. Through workshops, service design methods and virtual models, we help clients explore options early on and make confident decisions throughout the design process.

Product design

We design furniture and products when ready-made solutions are not enough. Our work is driven by functional needs and durable, space-appropriate solutions. We create one-off pieces, small series and products for industrial production, with a design language that is clear, timeless and tailored to each project.

We.

Protest Design is an interior architecture studio built on long-term collaboration. Our interior architects, Taina Lehtinen and Marko Nenonen, have worked side by side for over 20 years, combining their perspectives into thoughtful and well-balanced design.

Taina has a natural ability to see the bigger picture. She approaches each project by considering the architecture, history and character of the building, and she enjoys finding solutions that respect its essence while serving contemporary needs. Her interests range widely across architecture and design, and she brings thoughtful use of space and colour into her work. Taina also has experience in teaching and lecturing, which adds clarity and structure to the way she guides projects forward.

Marko Nenonen

Marko brings a curious and reflective approach to design. He likes to question, explore and understand the essence of each assignment, which often leads to solutions that feel both natural and subtly inventive. His strengths lie in details – furniture and lighting design, and he guides our clients into the world of virtual modelling and immersive presentations. Marko is also highly skilled in organising and managing projects, ensuring that the process remains clear and well-structured from start to finish.

We create environments that are functional, beautiful and made to endure. Each project begins with an open mind and a curious eye.
