Architechnics, Inc. is a company based out of Quincy IL that offers complete building design and planning services. This all includes architecture, cost estimating, structural design, mechanical and electrical design, facilities planning, and complete interior design.
This is a company that i am trying to get a job with and be their personal landscape architect, since currently there is a licensed architect doing the landscaping plans. They have some great projects and have a sketchup program that is alot better then sketchup called BIM or Building Information Modeling that creates a working digital representation of the physical and functional characteristics of the building.
