Open Floor Plan Conversions in Chicago: Removing Walls in Vintage Homes
Chicago's vintage homes—bungalows, two-flats, greystones, and Victorians—were built with floor plans that made sense in 1920 but feel cramped today. Small, compartmentalized rooms connected by narrow doorways don't accommodate modern lifestyles where cooking, dining, and living flow together. The solution? Removing walls to create an open floor plan.
But here's what every Chicago homeowner needs to understand: most walls in vintage homes are load-bearing. Unlike newer construction where partition walls are common, homes built before 1950 typically used interior walls as structural support. Removing one without proper engineering can cause ceiling sag, cracked walls, or structural failure.
Removing a load-bearing wall in Chicago costs $8,000–$25,000 per opening including structural engineering, steel or LVL beam installation, permits, and finishing. Full open-concept conversions combining kitchen, dining, and living spaces run $75,000–$150,000 when combined with a kitchen renovation. Timeline: 3–8 weeks for wall removal alone, 3–5 months for complete open-concept renovation.

Why Chicago Vintage Homes Have So Many Load-Bearing Walls
Understanding why your walls exist helps explain why removing them requires structural work. Chicago's vintage homes were built using construction methods that relied heavily on interior walls for support.
Chicago Bungalow
Typically 1.5 stories with living spaces on main floor. Central hallway with rooms branching off creates the classic "shotgun" layout with multiple load-bearing partitions.
Two-Flat / Three-Flat
"Railroad apartment" layout with rooms arranged front-to-back. Each unit was designed as separate dwelling with walls dividing living, dining, and bedrooms in sequence.
Greystone
Balloon-frame construction with continuous studs from foundation to roof. Interior walls provide lateral bracing and load distribution across 2–3 stories.
Victorian / Queen Anne
Complex floor plans with parlors, sitting rooms, and formal dining rooms separated by pocket doors and structural walls. Often 2–3 stories with irregular layouts.
⚠️ Load-Bearing vs. Non-Load-Bearing: How to Tell
In Chicago vintage homes, assume every wall is load-bearing until proven otherwise. Signs a wall is structural: it runs perpendicular to floor joists, it's located in the center of the home, there's a beam or wall directly below it in the basement, or it supports a wall on the floor above. Always hire a structural engineer ($800–$2,000) to confirm before demolition.
What Does Open Floor Plan Conversion Cost in Chicago?
Costs vary dramatically based on how many walls you're removing, what's inside them, and how much finishing work is required. Here's what Assembly Squad typically sees across different project scopes:
Cost Breakdown: What You're Paying For
| Component | Cost Range | Notes |
|---|---|---|
| Structural Engineer | $800–$2,500 | Required for permit; designs beam size and placement |
| Chicago Building Permit | $500–$1,500 | Structural work requires full permit review (6–10 weeks) |
| Steel I-Beam (installed) | $100–$400/linear ft | Strongest option; best for long spans (15–20') |
| LVL Beam (installed) | $50–$200/linear ft | Engineered wood; good for spans up to 20' |
| Support Columns | $500–$2,000 each | May be required for long spans; can be wrapped/hidden |
| Electrical Relocation | $350–$1,500 | Outlets, switches, junction boxes in removed wall |
| HVAC Duct Rerouting | $500–$3,000 | Common in vintage homes with floor/wall registers |
| Plumbing Relocation | $400–$2,500 | If wall contains supply lines or drain stacks |
| Drywall & Finishing | $1,500–$4,000 | Patching ceiling/walls, texture matching, painting |
| Flooring Transition | $500–$3,000 | Matching/replacing flooring where wall was removed |
| Temporary Shoring | $500–$1,500 | Required to support structure during beam installation |
| Two-Story Wall Removal | $15,000–$30,000 | Significantly more complex; larger beams required |
Steel vs. LVL Beams: Which Is Right for Your Project?
The beam that replaces your load-bearing wall is the most critical component. Here's how the options compare:
Steel I-Beam
LVL Beam
Glulam Beam
Flush Beam (Recessed)
Assembly Squad Recommendation
For most Chicago bungalow and two-flat wall removals, we recommend steel I-beams. Yes, they cost more than LVL, but steel beams are slimmer for the same load capacity—meaning more headroom and a cleaner look. In homes with 8' ceilings (common in Chicago), every inch matters. Steel also won't warp, rot, or attract pests like wood alternatives.
The Wall Removal Process: Step by Step
Understanding the process helps you plan for disruption and timeline. Here's how Assembly Squad approaches every load-bearing wall removal:
Structural Assessment
Engineer visits to analyze wall location, floor joists, foundation, and load path. They'll confirm if the wall is load-bearing and design the replacement beam system. This determines everything else.
Permit Application
Chicago requires building permits for structural modifications. We submit engineered drawings to the Department of Buildings. Standard review takes 6–10 weeks; expedited review available for additional fee.
Utility Discovery & Relocation
Before demolition, we identify and relocate electrical wiring, HVAC ducts, plumbing lines, and any low-voltage cables inside the wall. This prevents surprises during demo.
Temporary Shoring
We install temporary support walls or adjustable posts to carry the load while the permanent beam is installed. This protects your home's structure during the transition.
Wall Demolition
With shoring in place, we carefully remove the wall—drywall, studs, and top/bottom plates. In vintage homes, this often reveals original plaster and lath, knob-and-tube wiring, or other surprises.
Beam Installation
The engineered beam is lifted into position and secured. For steel beams, this often requires multiple workers due to weight. Posts or columns are installed if required. Inspector verifies placement.
Finishing Work
Drywall wrapping around beam (if not exposed), ceiling and wall patching, texture matching, painting, and flooring transition. This phase often takes longer than the structural work.
Real Chicago Wall Removal Projects
Here are three recent Assembly Squad projects showing actual costs and timelines:
1920s Chicago bungalow with classic closed-off kitchen. Removed 12' load-bearing wall between kitchen and dining room to create open entertaining space. Steel beam installed flush with ceiling. Original hardwood flooring patched where wall removed.
Owner-occupied two-flat deconversion. Removed two load-bearing walls to combine front parlor, middle dining room, and rear kitchen into one 35' flowing space. New kitchen with large island, unified white oak flooring, and modern lighting throughout.
Load-bearing wall running through first and second floors of 1895 greystone. Removed to create open living/dining on main floor and connected bedrooms above. Required two steel beams stacked vertically with reinforced foundation footings.
Chicago Permit Requirements for Wall Removal
Any structural modification in Chicago requires a building permit. Here's what you need to know:
Chicago Wall Removal Permit Checklist
- Building permit required — All load-bearing wall removals need Department of Buildings approval
- Structural engineer drawings — Stamped plans showing beam design, load calculations, and connection details
- Contractor license verification — Must be performed by licensed general contractor
- Standard review timeline — 6–10 weeks for permit approval
- Expedited review available — Additional fee for faster processing
- Inspections required — Rough framing inspection before closing walls, final inspection
- Electrical permit — Separate permit if relocating outlets/switches ($200–$500)
- Plumbing permit — Separate permit if relocating drain lines ($300–$800)
⚠️ Don't Skip the Permit
Unpermitted structural work creates serious problems: failed home inspections when you sell, insurance claim denials, liability if something fails, and potential orders to restore the wall. The permit process exists to ensure your home remains safe. Assembly Squad handles all permit applications and inspections as part of our service.
Common Surprises in Chicago Vintage Homes
When we open up walls in homes built before 1950, we often find things that add cost and complexity:
Knob-and-Tube Wiring
Many Chicago vintage homes still have original knob-and-tube electrical wiring. When exposed during wall removal, code requires replacement—not just in the removed wall, but often in connected circuits. Budget an additional $3,000–$15,000 depending on extent.
Plaster and Lath
Original walls used wood lath covered with plaster, not drywall. Matching texture and patching plaster requires specialized skills. Some homeowners use wall removal as an opportunity to replace remaining plaster with drywall throughout the main floor.
Hidden Ductwork
Vintage homes with retrofitted HVAC often ran ducts inside walls. Rerouting ductwork around a new beam opening can add $500–$3,000 depending on complexity.
Structural Deterioration
Once walls are opened, we sometimes discover deteriorated joists, pest damage, or prior "improvements" that weren't done correctly. While concerning, finding these issues during a planned renovation is better than discovering them during an emergency.
Design Considerations for Open Floor Plans
Removing walls is the structural part. Creating a cohesive open floor plan involves design decisions that affect daily living:
Kitchen Visibility
Open floor plans mean your kitchen is always on display. If your cabinets are dated or countertops worn, opening the wall makes this more obvious. Many homeowners combine wall removal with a kitchen renovation for this reason.
Sound and Smell Travel
Without walls, cooking odors reach living areas and conversations carry throughout the space. Consider range hood upgrades (600+ CFM) and acoustic treatments if noise is a concern.
Heating and Cooling Balance
Open floor plans change how air flows through your home. Vintage homes with radiator heat often need rebalancing after wall removal. Forced-air systems may need duct modifications to heat/cool the larger combined space effectively.
Flooring Continuity
Where walls separate rooms, flooring often changes. Removing walls exposes mismatched flooring that looks jarring. Plan for flooring replacement or creative transitions where materials meet.
