Eigelberger A+D understands that architecture needs to be rooted in the land and must respond to the natural and built environment.  The local materials, vernacular and urban or rural density must be taken into account to merge the building into the landscape and provide seamless living environment that embraces the outdoors and brings warmth to the interiors.  Taking into account the Client's needs and the environment, we artfully respond to each site's unique context and provide sustainable solutions to the architecture.
Our goal is to provide a personalized service from the project inception to the completion and long after.  We strongly believe that projects and clients grow and that our involvement beyond construction provides an enormous value to preserving the intent of the project, aiding in proper maintenance and the possible continued growth of the project.
