Our Services

From Lincoln Park to Logan Square, we craft every square foot to match your vision and Chicago’s exacting building codes.

Home Additions

We pour frost-protected footings, frame with engineered LVL beams, and tie new rooflines into existing trusses for seamless curb appeal. Every addition is insulated to Chicago energy code and finished with Hardie siding for zero-maintenance longevity. Expect permits pulled, inspections passed, and zero surprise change orders.

ADU Builders

Navigate Chicago’s ADU ordinance with us: we handle zoning analysis, utility lateral sizing, and separate-meter installs. Our garage conversions include radiant slab heating and egress-compliant windows to turn unused space into rentable studios. End result: legal rental income from day one.

Kitchen Remodeling

We re-route gas lines for pro-grade ranges, install soft-close plywood cabinetry, and under-cabinet LED strips that disappear until you flip a switch. Quartz waterfall islands anchored to new L-braced framing handle 500 lb loads without flex. Every backsplash tile is laser-leveled for grout lines you can’t slide a card into.

What Sets Us Apart

We treat every job like it’s our own South Side bungalow-no shortcuts, no excuses, just rock-solid work that stands up to Chicago winters.

Built to Last

We use pressure-treated plates, stainless fasteners, and ZIP System barriers so your addition outlives the mortgage. Every structure is backed by a 5-year workmanship warranty.

Design-Build Control

Our in-house designers draft in Chief Architect and hand specs straight to crews. One team, one call-no finger-pointing between architect and builder.

On Budget, On Time

Fixed-price contracts with line-item allowances. We hit milestones weekly; if we’re late, we pay the per-diem. That’s the MB guarantee.
