Individual Sunroom and Room Addition Design

Each Millennium construction project is unique; architecturally designed to accommodate the individual wishes of our customers. We are not restricted by the limits of modular systems and can consequently offer much greater flexibility in design. This allows us to take into account specific features of your existing property: window styles, brickwork, roof lines and other architectural details, in order that the finished room addition or a sunroom blends more completely with the character of the existing structure. With more than 15 years of experience in a construction business our team understands the conditions and a climate of Illinois and Northwest Indiana, as well as the challenges and the excitement of completing your home project.

Complete Sunroom Construction Service

We offer a complete service, carefully managing the project through each stage, from the initial survey and design through to the manufacture and installation of your home improvement project. In this way we believe we can best ensure total satisfaction while relieving you of the burden of co-coordinating various individual organizations. After an initial visit from one of our dedicated team member to discuss in detail your ideas and requirements and to survey your property, an individual proposal will be prepared showing suggested design options and a cost. We will provide you with unique and practical design ideas and insights from our knowledge and experience. Once the specific design has been agreed we will obtain architectural drawings and a building permit if required before proceeding.

Quality & Excellence with the Owner of the Business On-site at every Job

Quality is carefully monitored at every stage of manufacture and installation of your home improvement project, and as part of our personal service you will receive regular reports of ongoing progress until final completion and handover.

This process eliminates the high-pressure salesman and reduces costly overhead to the project. Your ideas will be heard, your needs evaluated and all your questions and concerns will be answered. Millennium Construction will give you all the time you need to decide.

A Pleasure to Work With

I met with David at Millennium to discuss our current situation. I thought he was very pleasant and knowledgeable. He and his crew worked very hard to build us what we wanted. He was a pleasure to work with. I thought the quality of the job was fantastic and our screen room looks great. I recommend Millennium construction to anyone looking for a job well done.

Composite deck

My husband and I hired Millennium Construction to build a custom deck. We chose Millennium over other estimates because the owner, Dave, was very professional, knowledgeable, and trustworthy. We told Dave what he had in mind and he designed our deck within minutes. Dave also introduced us to composite wood for the materials. His staff is also professional and excellent workers. The smallest concerns were handle immediately. I look forward to working with Millennium Construction for a future room addition.

Deck around the pool.

After meeting with David from Millennium Construction I knew they were the right company to construct a deck around my new pool. David is very knowledgeable and made sure I got exactly what I wanted. They worked fast, were very courteous and the deck turned out great. I am very happy with it and would definitely hire them again in the future. Thanks for everything, David!!

Fantastic Custom Deck Plano

The deck is perfect and has all the details of a truly great builder. Beautiful deck and the consultation David gave us was awesome.

Hard Working, Fair Pricing

David and his crew were prompt with the initial appointment, hard working and detail oriented. They were concerned about the little “particulars”. David’s pricing was fair and competitive. Clean up was as though they were never there! Each day our backyard was completely cleaned up. David is a great carpenter. I am looking forward to calling him in the future for our basement remodeling. Millennium construction was a great “blind” internet find.

Ipe deck

I have never met a contractor like David before. He spent countless hours working with us on our IPE Deck. David took the time to design a one of kind deck. The time he spent with us enabled him to build us a deck that perfectly matched what we envisioned but could not design. David is always available, no matter the day or time he will always make time for you. I would hire him for a future project and have recommended him to friends. Source:

Room Addition: Exceeds Expectations ...

When getting bids for my room addition project, one of the first things that stood out about Dave at Millennium was that he was just as excited about out room addition as we were. He spent plenty of time with us and using his laptop computer he produced a preliminary design our project, showing the dimensions, walls, fixtures and features that we asked for. His bid was extremely reasonable. Dave managed all aspects of the project, bringing in his crew of experts and at the end of the day, they took plenty of time to clean and sweep the construction debris before leaving the job site. Throughout the project, family, friends and neighbors, stopped by to look, and they couldn’t help but comment what a nice job Dave and his crew were doing, and were impressed at the high quality of workmanship, materials and attention to detail. The end product exceeded our expectations, and the suggestions that Dave made to our room addition turned out to be the showcase features of the project. We highly recommend the professionals at Millennium construction to everyone – you will not be disappointed.
