New two-story brick home addition under construction in Lincoln Park
Home Additions
We pour frost-protected foundations, frame with LVL beams and ZIP sheathing, then match new brick and siding to your existing façade. Every addition ties seamlessly into your plumbing, HVAC and electrical systems so it feels like it was always part of the house. Typical 400 sq ft family-room addition is dried-in within 10 days.

We deliver durable renovations on schedule and within budget, backed by 30 years of Chicago-area expertise.

Durable Quality

We use ZIP System, LVL beams, and copper plumbing-materials that stand up to Chicago freeze-thaw cycles. Every job is third-party inspected before drywall goes up.

Personalized Design

Our in-house design team creates 3D renderings so you can see finishes and flow before we break ground. Changes happen on screen, not on your dime.

On-Time Budget

Fixed-price contracts and weekly Gantt charts keep projects on track. Average kitchen or bath finishes within 2 days of schedule and 1% of budget.

What our clients say.

"MB added a 500 sq ft family room off our kitchen in Old Irving Park. Crew showed up at 7am daily and we hosted Thanksgiving in the new space right on schedule."

"They converted our dusty Lincoln Square attic into a bright guest suite with dormers and skylights. City inspections passed the first try and the punch-list was only five items."
