Two brothers, one design language.
Delfin Design is an Istanbul-based architecture, interior architecture and implementation studio. The foundation of the studio is shaped by the shared production culture of two brothers who grew up in the same home and studied architecture in the same schools.
What We Value
At Delfin Design, we see simplicity not as emptiness, but as the result of deliberate decisions. Every material, every light source, every furniture detail and every line in a space should have a reason.
For us, good design is not about creating showy but weak solutions. It is about making applicable, long-lasting decisions that fit the user's life.
That is why we value spaces that are simple, clear, characterful and sustainable. We approach sustainability not only through material choices, but also through spaces that retain their value over time, reduce unnecessary consumption and function properly.
Our Story
Delfin Design was founded through the shared production culture of two brothers who followed the same educational path. Our interest in architecture has evolved over the years into a design approach that brings together interior architecture, lighting, material, detail and implementation processes.
In residential, villa, office, café and restaurant projects, we evaluate each space according to its own scale, user and context. From the design process and 3D visualization to material decisions and implementation follow-up, we aim to manage different stages within a consistent design language.
We do not begin projects with ready-made formulas. We begin by understanding the real needs of the space. This approach forms the foundation of Delfin Design's aim to create simple, functional, timeless and characterful spaces.
Our design principles
At Delfin Design, responsibility begins with making the right decisions. For us, good design is not only about creating a visually strong space; it is about shaping interiors and architectural environments that are long-lasting, functional, applicable and free from unnecessary excess.
We approach every project through proportion, material, light, detail and real use. Our aim is to design spaces that feel clear, balanced and characterful today, while preserving their value over time.
- 01
Long-Lasting Decisions
We make design decisions through materials, proportions, details and user scenarios that can stand the test of time. Instead of short-lived visual effects, we focus on spaces that remain meaningful, useful and refined as they are lived in.
- 02
Material and Detail Discipline
We do not select materials only for their appearance. We evaluate texture, durability, maintenance needs, usage intensity and implementation conditions together. This approach helps the design remain consistent from concept to site.

Light and Spatial Quality
Natural light, artificial lighting and atmosphere are central parts of our design process. We consider lighting not as a final decorative layer, but as a tool that shapes the experience, comfort and identity of a space.

Implementation Reality
A design decision is only valuable when it can be applied correctly. For this reason, we consider production, installation, material choices, technical details and site coordination as part of the design process. Our goal is to protect the integrity of the design from idea to implementation.

A Realistic Commitment
We avoid claims that cannot be measured or proven. Instead, we focus on making fewer but better decisions in every project. For Delfin Design, responsibility means creating spaces that are simple, functional, durable and meaningful — without unnecessary noise.
Yunus Güler
My journey in architecture began in the Building Architecture department at İSOV Anatolian High School. In 2016, I graduated from the Department of Interior Architecture at Işık University. I then completed my master's degree in Industrial Design and Innovation Management at Bahçeşehir University in 2019.
Through a patented material I developed, I continue to explore the relationship between light and space, both in its functional role and in the layers of meaning it can create.
My office and field experience, which began during my high school years, has expanded through projects of different scales.
Since 2019, I have continued to design, produce and transform spaces within the studio I founded, focusing on interior architecture and lighting design. In my design approach, I particularly embrace a minimalist, timeless and balanced language. I prioritize creating spaces that are simple yet full of character. I see design not only as an aesthetic practice, but also as a search for meaning and balance.

My journey in architecture began in the Building Architecture department at İSOV Anatolian High School. In 2019, I graduated from the Department of Interior Architecture at Işık University. Throughout my university years, my interest in details and my aptitude for digital production became the foundations of my design approach.
I value the balance between aesthetics and function in design, and I focus on creating spaces that are simple yet impactful. By using my strengths in digital design and production processes, I aim to develop solutions that reflect the unique character of each project.
As a co-founder of the studio, I take an active role at the center of the design and visual communication processes. With a digital-focused, detail-oriented and innovative perspective, I contribute to bringing projects to life. I see design not only as shaping spaces, but also as creating livable, meaningful experiences that make people feel good.

While studying Media and Communication Systems at Istanbul Bilgi University, I also took various professional courses on social media and digital strategies at the University of California, Los Angeles (UCLA). This process gave me a deeper perspective on how brands are positioned in the digital world.
For six years, I worked as a digital marketing specialist at a global company. The experience I gained in brand management, campaign strategy, performance analysis and user experience strengthened my ability to think strategically.
At Delfin Design, I position not only our own brand, but also the brands we work with, through a consistent, strong identity aligned with their digital presence.
I see design not only as an aesthetic expression, but also as a strategic form of storytelling. I care about building a communication language that reflects the spirit of each brand in every detail.
