Providing superior architectural design and client care services.


Combining nearly seven decades of beautiful and responsible architectural design, construction documentation and personal client service experience, TDG Architecture is uniquely suited for special projects that require creative problem solving and excellence in project management. Our award winning designs are grounded in a practical and collaborative approach with our clients to establish a design solution that will bring the most beauty, sustainability and value to every building and space. This approvable design strategy has provided an opportunity to help public and private clients succeed in residential, commercial, industrial, and mixed-use projects throughout the area.

TDG Architecture was created in early 2008 by the former partner of Colorado Architecture Partnership, Mark Tremmel. TDG works to provide superior architectural design and client care services for Colorado Springs and the surrounding region. Trained to the most current digital drawing standards, TDG has the capacity to envision and detail every project to exacting professional standards while conforming to rigorous budgets and schedules.


We have extensive experience working with neighborhood and government agencies, such as the City of Colorado Springs Regional Building Department, City Development & Planning Services, and other regional planning organizations to provide our clients with approval-ready projects. Our public client experience includes working with the City of Colorado Springs Utilities; City Parks, Recreation & Cultural Services; and University of Colorado at Colorado Springs on projects that span two decades.

Our residential experience covers assisted living, multifamily and private residences with both new construction and renovation on a variety of local, regional, and international projects.

Our projects provide value to the owners and to our community. With all four of the professionals of the firm as Leadership in Energy and Environmental Design Accredited Professional (LEED AP’s), TDG is experienced in energy saving design and built-green award-winning residential creations. We have worked with the USGBC to achieve LEED Certified Silver Award for the Colorado Springs Utilities Water Laboratory (in association with RNL Design of Denver) and the Summit County Built-Green Award exemplify our commitment to sustainable design and healthy built environments.

TDG holds architectural licenses in Colorado, Arizona, California, Nebraska, and Texas.


Design Collaboration is the most critical service we provide. Working with clients and our many essential engineering and design consultants involves constant collaboration. It is how things get done, and done well.


Project Management is the logistics of how a project gets put together and built. A project manager is the project lead and responsible for coordinating all the moving parts that come with Architecture. It is a tough job, but a very important one to the success of our projects.


Sustainability is inherent in all of our designs. We believe in the importance of utilizing energy-efficient design strategies, and designing buildings that do not burden the existing landscape and environment. The majority of our employees are LEED accredited professionals.


Space Planning or programming means the strategic placing and development of design functions. How do these parts and pieces make up the entire project? It is big-idea thinking with lots of trace paper, colored markers, and bubble diagrams.


Over the years, we have been rewarded recognition for a myriad of our projects, commercial and residential architecture alike, from Colorado to Texas. We are proud of our expertise in each area of architecture and design and continue to push forward with the best design possible. Check out some of our award-winning designs below.



During every step of the process, we are paying attention to you: what you are saying, and what you are not saying and everything in between.


Actively listening is not just about hearing what our clients are saying. We are paying attention, taking notes, and engaging by being inquisitive. The questions we ask are not just to create total transparency between us and our clients. We ask the questions that will improve our clients vision and meet their spoken and unspoken needs and wants.


Once we fully understand your needs, we then dive head first into the creative design process. This is where our knowledge, our experience, and certifications take over to produce beautiful structures.


No project is complete until it has been thoroughly tested and evaluated. We double and triple check every aspect of our projects. Quality control is a core aspect of what we do, and we are not finished with a job until our clients are 100% happy with our work.


TDG Architecture is an award-winning, Colorado Springs-based architecture firm dedicated to sustainable and beautiful design. At TDG, every project, commercial, residential, or planning, deserves the highest quality of client care and design collaboration, benefitting the client’s project. Every step of the way, both behind the scenes and in client meetings, TDG Architects are finding opportunities and creative solutions that go beyond average architectural design.
