We are a team of architects and interior designers operating under the combined brands KC InterioR Plan & Saku Designe. 

We specialize in both standard interior arrangements and premium design projects that combine functionality with exceptional aesthetics.  By working with us, the investor receives full support – from functional concept development, through 3D visualizations, to technical documentation and architectural supervision – ensuring that every interior is refined down to the smallest detail. 

We create interiors in Japanese, minimalist and loft styles, ensuring spatial harmony, consistency, and the highest quality of detail. Our projects combine well-considered ergonomics with the individual character of each design, while remaining faithful to the philosophy of simplicity and natural materials.

Together with ARTA PROJEKT ARCHITECT STUDIO, We also deliver bespoke single-family house designs and other building projects, comprehensively managing the process of obtaining a building permit. Our experience covers a wide range of fields – from architecture and interior design to steel structures, general construction, and timber frame solutions. 

Thanks to our ability to listen carefully to our clients’ needs, we create interiors with soul – full of light, harmony, and a welcoming atmosphere. 

We warmly invite you to collaborate with us.
