Windsor Homes began in 1993 as a custom home building and commercial construction company.

As we saw an opportunity to expand our construction services, Windsor Development Group was founded in 2000 to facilitate affordable housing developments—transforming communities brick by brick.  Our team lives and works in Central Illinois where our residential and commercial projects develop, which makes us very accessible to our clients.  Our portfolio contains everything from a 14,000 square foot forensics lab to a custom campground bathhouse, as well as attractive affordable housing.  No matter the size of the job, we commit one hundred percent to our clients.

We invite you to learn more about the Windsor team and the breadth of experience and talent they provide.
