BURØ SIMPELT is an architecture and interior design practice working between Istanbul and Lisbon.

Büro Simpelt is an architecture and interior design practice founded in 2020 by architects Yiğitcan Ülkücü and Nazlı Ünsal. Working between Istanbul and Lisbon, the studio approaches architecture and interiors as one continuous spatial discipline, from the organisation of a building to the material encounter of a joint, handle or piece of furniture.

Its work begins with the site, the client and the conditions already present. Rather than applying a fixed visual language, the studio develops each project through observation, dialogue and construction. Simplicity is understood not as emptiness or a commercial image of minimalism, but as clarity: a calm and legible framework in which life can accumulate over time.

Across residential, healthcare and emerging hospitality projects, Büro Simpelt seeks to create spaces that are carefully reasoned, materially honest and capable of remaining meaningful beyond the first impression.

Design was a shared language between Yiğitcan Ülkücü and Nazlı Ünsal long before it became a shared practice. Friends since their first year at architecture school, they travelled to see buildings and exhibitions, spoke constantly about design, and developed their experience in other offices before establishing Büro Simpelt in Istanbul in February 2020. Their first commission was the interior of a triplex house in Bodrum, begun just before the global lockdowns.

The name grew from a series of visits to Copenhagen that began in 2014. What stayed with them was not a visual style, but a culture in which simplicity, craftsmanship and everyday use appeared closely connected. The work of designers and makers remained visible and valued. “Simpelt” became a reminder that simplicity is not emptiness; it is the result of understanding what is necessary.

From the beginning, the studio also took responsibility for construction. Contracting early projects, a house in Ankara and a clinic in Istanbul, made the distance between drawing and building impossible to ignore. It established an approach in which constructability, material knowledge and dialogue with craftspeople are part of design itself. Today, the practice moves between Istanbul and Lisbon. Istanbul has taught speed, adaptation and improvisation; Lisbon has introduced patience and a slower form of observation. The studio works between these complementary energies rather than adopting a single geographic identity.
