Grun Development is a Chicago area green developer and builder committed to bringing energy star certified housing to the urban market. We offer high quality construction, tax incentives, lower mortgage rates and 65% energy savings built into our structures. Along with outstanding energy efficiency savings, our dwellings feature the use of sustainable living products, including low VOC coatings and paints, non-formaldehyde insulations, and sustainable growth wood flooring products.



Grun currently has three energy star homes nearing completion at 2652 W Walton (see google map). Each single family home provides 4150 square feet of space. Included are 4 bedrooms, 3 baths and a detached two car garage. Our energy star certification is earned through tight construction practices and the use of products such as GE energy rated appliances, recycled cellulose insulation (dense packed for an R-40 rating) and open cell foam sprayed into the joists to halt thermal convection.

See construction photos for more details.
