Welcome to the world where creativity meets structure, where dreams are drafted into reality, and where every line on a blueprint is a promise of innovation and sustainability. At KOLM PLUSS ÜKS OÜ, we are not just architects; we are the visionaries behind the landmarks of tomorrow.

Our journey began with a simple yet profound mission: to specialize in architectural design, urban planning, and providing expert assessments for building projects. We believe that architecture is more than just constructing buildings; it's about creating environments that inspire, connect, and endure.

From the bustling streets of Tallinn to the serene landscapes of Tartu, our portfolio is a testament to our versatility and dedication. Projects like the SÜKU: Tartu Downtown Cultural Centre, the Siili 4 Apartment house, and the visionary Kiigele for the Tallinn Song Festival Grounds showcase our commitment to excellence and our ability to transform communities through thoughtful design.

Our team of skilled architects takes pride in every project, whether it's a residential district like Aruküla or an educational complex like Raadi. We approach each challenge with a fresh perspective, ensuring that our designs are not only aesthetically pleasing but also functional, sustainable, and integrated with their surroundings.

At KOLM PLUSS ÜKS OÜ, we are driven by our slogan, 'Designing Tomorrow's Landmarks!' It's not just a tagline; it's our commitment to you and to the future. We invite you to explore our works, join our vision, and together, let's build the landmarks that will define our cities for generations to come.
