From bungalow bump-outs to coach-house ADUs, we add livable space across Chicago neighborhoods.

Two-story rear addition under construction with matching brick and windows
Home Additions

We integrate new foundations, rooflines, and HVAC into existing structures so the addition feels original. Our crews handle structural steel, brick matching, and seamless siding blends. All plans are engineered for Chicago snow loads and wind codes. You get a full room count increase without a full move.

Sun-filled family room addition with vaulted ceiling and skylights
Room Additions

Need a main-floor office or a bigger primary suite? We frame, insulate, and finish new rooms in as little as six weeks. Electrical and plumbing tie-ins are routed through existing chases to cut drywall damage. Each addition is spray-foam insulated to meet current energy code. Enjoy the extra square footage without losing yard space.

ADU Construction

Turn your garage or side yard into a rentable coach house or in-law unit. We pull the zoning permits, run separate utilities, and install fire-rated egress windows. Every ADU meets Chicago’s 2023 ordinance for ceiling height and off-street parking. Start collecting rental income the day we hand over the keys.

Modern white kitchen with island, pendant lights, and subway tile
Kitchen Remodeling

We gut to the studs, relocate plumbing, and install custom cabinetry built for your cooking style. Quartz counters, tile backsplashes, and under-cabinet LED lighting come standard. Our crews work in phases so you can still make coffee every morning. Walk into a magazine-worthy kitchen without leaving your house.

Basement Renovations

Lower-level living space adds square footage without changing the roofline. We install egress windows, sump pump upgrades, and in-floor radiant heat for year-round comfort. Framing, drywall, and built-in storage turn dark storage into bright rec rooms. All work is permitted and inspected to Chicago code.

Whole-Home Remodeling

When one room is not enough, we redesign the entire layout for open-concept living. Load-bearing walls are replaced with engineered beams to create sight-lines from kitchen to family room. Flooring, paint, and fixtures are selected to flow seamlessly. Live in a brand-new house inside your existing address.
