Common Remodeling Challenges for Homes in River West, Chicago, Illinois Include:

In River West, additions usually mean expanding the neighborhood’s townhomes and the rare single-family homes, or finishing and reconfiguring loft and condo space, rather than ground-up wings. We design River West additions and build-outs that work with the building’s structure, with Chicago Department of Buildings permits handled.

Townhome & Loft Build-Outs

River West additions often mean expanding townhomes or finishing and reconfiguring loft space. We design within the building's timber or concrete structure.

Rooftop & Penthouse Work

Some River West buildings allow rooftop or penthouse build-outs. We evaluate structure and association rules before designing.

Chicago Department of Buildings Permits

Additions and build-outs pull a Chicago Department of Buildings permit and zoning review, which we manage.

The Right Approach For Your River West, Chicago Home Addition

Whether you need to add extra room for a growing family or a second level to your home, our team will help you find the best way to expand your space.

Single Level Additions

If you find yourself needing more living space and want to expand your home rather than upsize, a single-level addition is the place to start.

The most cost-effective way to add living space, a single-level addition attaches to the side of the home. They typically require expanding the home’s foundation, and are most often used for expanding kitchens, living rooms, or home offices.

Single-level additions are typically limited by lot size and setback laws. For this reason, these additions are better fit for homes on larger lots.

Second Story Additions

Want to expand your home without expanding its footprint? Many homeowners don’t realize it’s possible to expand their living space by adding a second story.

Although often more expensive than single-level additions, second-story additions can be a great solution for homeowners who need additional living space but don’t have enough yard space to build out.

Second-story additions tend to be more technically challenging, as they require extensive engineering and planning to ensure that they don’t disrupt the design or aesthetic of the existing structure.

Basement Additions

For some homeowners, a basement addition is the best way to expand their living space. This often involves either raising the home or digging out the crawl space.

Homeowners who go this route often use their basement for additional bedrooms, a recreational space, or an Accessory Dwelling Unit (ADU).

Basement additions are among the most expensive methods of adding onto a home. Extensive manual labor, planning, and permitting all contribute to the high cost of basement additions.

Frequently Asked Questions

Can my River West home support a second-story addition?

For townhomes and the rare single-family homes, often yes with verification. In multi-unit loft and condo buildings, vertical additions are highly complex. We evaluate the structure and involve an engineer first.

Is a dormer or attic conversion more cost-effective than a full addition in River West?

For top-floor units, a rooftop or penthouse build-out can be the most practical way to add space. We compare options for your specific building.

How much does a home addition cost in River West?

In River West, additions typically run $325 to $525 per square foot depending on scope and finishes. We provide a fixed budget after design.

How long does the Chicago Department of Buildings take to approve an addition permit?

Approval for a River West addition through the Chicago Department of Buildings often takes a couple of months depending on scope and zoning. We prepare complete drawings and manage the process.

How do you match a new addition to my existing River West home?

We document the building’s masonry, timber, or new-construction detailing and source matching materials so the work integrates cleanly.

What zoning and setback rules apply to additions in River West?

The Chicago Department of Buildings enforces zoning and setbacks, and loft and condo additions also depend on association and building constraints. We confirm everything first.
