Three- and four-season rooms designed for Chicago winters, not just summer weekends.
A three- or four-season room bridges indoor comfort and outdoor space, letting you use the room through spring, fall and, with the right insulation and glazing, winter too. We design each one around how the room ties into the existing house.
A mini-split is often the piece that makes the difference. It heats and cools the room on its own without touching the main furnace, which is why they have become so common on season rooms and small additions in the last few years.
Built to stay comfortable through a real Chicago winter.
Conditions the room independently of the main system.
Reads as part of the original home, not an add-on.
We manage municipal approvals across every town we work in.
