The Knowlton Group Architect
The Knowlton Group believes that architects should carefully take cues from a project’s site, listen intently to clients, and conduct thorough research before putting pencil to paper. As a design develops, The Knowlton Group emphasizes the need for contractor involvement to provide expertise in how to bridge the gap between ideas and reality. During the construction phase, The Knowlton Group believes that the architect’s eye is critical and necessary to ensure the accurate execution of the design. Moreover, sustainability is an ever-growing field and will undoubtedly become increasingly pervasive. The Knowlton Group believes that a design and building process that does not consider sustainable practices lacks responsibility and vision.
