We are a Danish architectural firm working in Scandinavia, Europe, and North America. Christensen & Co Architects (CCO Architects) was founded in 2006 with the ambition to create high-quality architecture, where innovative solutions contribute to sustainability and ensure long-lasting quality.

In 2024, RITA arch, an interior design and interior architecture firm, became part of CCO Architects. RITA arch was founded in 2018 with a mission to create spaces that are inspiring to use and inhabit. The mission and values ​​are still intact and continue as part of CCO Architects. The work of being design-strategic with a focus on corporate culture, values, and brand, and the work of creating interiors that are based on the customer’s identity and needs, contribute to greater employee well-being and can therefore be seen on the bottom line continues at CCO Architects.

What we do

CCO Architects assists public clients and private companies in translating visions and desires into new physical spaces of high architectural quality. We work with all phases of construction from initial sketches and clarification to the final delivery of the building, including interior design, special furnishings, and wayfinding.

We work based on research and analysis, in an interdisciplinary process where our skills are combined with valuable input from our clients and users. Our approach is analytical and ensures a unique integrated solution in each project.

Our strong focus on architectural quality and our effective collaboration with our clients has resulted in more than 500,000 m2 of constructed buildings of high architectural quality for:

Additionally, we are experts in process management, user involvement, and universal design.

We offer a full range of planning and design services, from small renovations and transformation projects to new constructions and state-of-the-art facilities. Regardless of scale, size, or budget, we work diligently to develop and deliver solutions that strive to be socially, economically, and environmentally sustainable, meeting the needs and ambitions of our clients and supporting the ethos and strategic goals of their organizations.

We thrive on close collaboration with our clients, their users, and other collaborators—from engineers, contractors, and other architects to change management consultants, logistics experts, and specialists in various fields. We believe that collaboration is the key to creating the best, most flexible, and future-proof buildings of high architectural quality.

This has resulted in numerous recognitions, including awards for our projects and positions of trust held by our talented colleagues.

In our work to develop innovative solutions and buildings, we draw on experiences from a range of pioneering, innovative projects, including timber construction (CLT). We integrate Life Cycle Assessment (LCA) and Life Cycle Costing (LCC) in our projects, a practice we have followed for several years.

We have groundbreaking projects in timber construction (CLT), such as DTU Climate Challenge Laboratory, Heerup School, and Kistefossdammen Kindergarten. We also work on Design for Disassembly in projects like NOL and DTU R3 Platform B112.

Who are we?

We are a creative professional community of around 50 dedicated and talented architects, engineers, and humanists. Our office is in the creative part of Nørrebro. Every day, we challenge conventional thinking through innovative architecture that creates value for people and the environment.
