MB Home Additions & Room Additions has been Chicago’s trusted general contractor since 1995. We design and build custom room additions, ADUs, kitchens, bathrooms, and full-scale remodels that fit your lifestyle and your lot.
From Lincoln Park to Logan Square, we craft every square foot to match your vision and Chicago’s exacting building codes.
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.

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.

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.
Get a QuoteWe 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.
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.
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.
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.
We let the work speak - but here's what a few clients have said after moving back in.
"MB added a 400 sq ft master suite over our garage in Lakeview. They matched the brick perfectly and finished two weeks early. The inspector shook their hand."
"Our basement went from damp storage to a rentable studio with a full bath. They handled city permits and even coordinated Comcast pull-through. Zero hassle."
