4-D Construction of Illinois, Inc. is a construction and renovating business that has a mission with a vision. Their mission is to plan, prepare, and complete any project in a way that makes a difference beyond just the physical aspects of the job – the finished product is targeted to be inspirational for their customers by going beyond normal and creating spaces that change your business, church, or home environments in ways that enhance lives. Their vision comes from their architectural sciences expertise and they create a 3-D digital model that can be used to visualize any project, new construction or renovation, and it’s spaces before it’s built.

The Company was formed in 1985 by president Dennis Rassi and 4-D has gained a sterling reputation that has been built on dependability, understanding customer requirements, quality workmanship, quality construction products, and customer confidence and peace of mind. In 2009 Dennis’ son Denver joined the organization with a degree in Architectural Sciences from the University of Illinois and brought with him a unique talent for making projects a visual reality before construction begins which gives everyone a chance to make any changes necessary to turn the finished product into one that reflects the charisma and essence of personalization that makes owners satisfied and proud of the visual results.
