Our approach to design and building, much like the ancient Japanese art of Bonsai, is a holistic one

BONSAI is an architecture firm focusing on high performance, sustainable residential and commercial design. We are also a general contractor who specializes in residential construction. We currently hold architectural registration in the state of Colorado, and a residential contractor’s license in the City and County of Denver, Wheat Ridge, Lakewood, Arvada, Greenwood  Village and Jefferson County. We are fully insured with professional Errors and Omissions and General Liability coverage for both of our design and build practices.

Our passion and mantra is high performance design and construction. We believe that one of the most effective ways to create sustainable architecture is to breathe new life into an existing structure. As such, we have vast experience in remodels, retrofits, restorations and renovations of historic and existing structures. Our knowledge doesn’t stop there, as we also have a large portfolio of new design and construction in additions, single family, duplexes, town homes and multi-family.

We look at each project as an opportunity to solve problems. This could be by creating something beautiful out of what may otherwise have been discarded, or cultivating a new vision. We look at the overall process, a complicated yet subtle journey. Only then, a building arises based on the aesthetic of its function and performance. Like the ancient art of Bonsai, architecture is the product of painstaking hard work, patience, and ingenuity

Whether it is a simple remodel or a large scale multi-family development, harmony with our environment is always on the forefront with every project we take on. Our staff is well educated and trained in both the Biotecture systems and Passive House building science principles. These fundamentals are implemented into each design within a budget and vision threshold

reduce or eliminate thermal bridging

airtight building envelope

high performance fenestrations

moisture recovery whole building ventilation

exploit sun for heating or solar gain management

If these basic principles are followed through in the design and construction effectively, minimal conditioning systems are required. The result is unmatched user comfort, superb indoor air quality, and unparalleled energy efficiency. We design and build with our environment, not against it.

The Architect-Led Design + Build business model makes sense in this increasingly contentious industry. ALDB blurs the lines traditionally seen between an architect and contractor relationship. We offer a holistic approach to the process of creating architecture. The evidence lies in the success of our designs and high caliber construction projects.
