When a Oak Brook kitchen needs more room, not just new cabinets
Sometimes no layout can fix a kitchen that is simply too small. A kitchen addition in Oak Brook — a bump-out of a few feet or a full rear addition — adds floor space for an island, a table or a pantry, and we handle it from the zoning check and permit drawings to the foundation, roof and finished cabinets.
A 1970s kitchen on a slab or crawlspace
We match the new foundation to the old one, whether a basement wall, crawlspace or slab, so floors line up and plumbing can reach.
A back door or deck in the way
The rear wall often has a door, steps or a deck. We plan the new entry, move or rebuild the steps and adjust the deck as part of the job.
Kitchen too small for an island or table
If you eat standing at the counter because there's no space for chairs, adding floor area is the honest fix, and a bump-out is often enough.
More appliances than the electrical panel can take
New space and new appliances can overload an older panel. We size the electrical work for the whole kitchen, not just the addition.
No spot for a mudroom or drop zone
Coats, shoes and backpacks pile up on kitchen chairs when the back door opens straight into the cooking area. A rear addition can put a bench, hooks and lockers between the yard and the kitchen.
Zoning and setback questions
Setbacks, lot coverage and sometimes floor-area limits decide how far you can build out. We confirm them early with the village's zoning rules.
Worried about living through construction
We build the shell first and break through the old wall late in the project, which keeps the time without a kitchen as short as possible.
What the project covers
- Feasibility and zoning checkA first look at what the property and the village's zoning allow, so the design starts within limits.
- Design and permit drawingsDrawings for the addition and the new kitchen, prepared for plan review and construction.
- Permits and plan reviewWe submit the permit application, answer the plan reviewer's comments and schedule inspections.
- Framing and roof tie-inNew framing connected to the house, a roof that ties into the existing one and a weather-tight shell.
- Windows, doors and exterior finishExterior cladding, windows and an entry door that blend with the original home.
- Insulation and drywallEnergy-code insulation, air sealing and finished drywall in the new space.
- The new kitchenCabinets, counters, backsplash, flooring and lighting installed across the old and new space.
Choices you'll make
Rear kitchen additionA full room added at the back, giving the kitchen space to grow and room for more.
Matching exterior materialsBrick, siding and trim sourced to match the house as closely as possible.
Cantilevered bump-outFor a small projection, framing that hangs off the existing floor can avoid digging, if the structure supports it.
Windows and patio doorsA row of windows, a sliding or hinged patio door, or a skylight brings daylight into the new space.
Banquettes and built-in seatingBuilt-in benches along the new windows make a compact eating nook with storage underneath.

AfterAn Oak Brook raised ranch: before and after
The site: a raised ranch in Oak Brook. Before: dark stained oak cabinets with wide face frames and a scalloped wood valance over the sink, harvest-gold laminate and a large fluorescent light box. What bothered the owners most: a cramped kitchen with one small window. Finished kitchen: the kitchen extended by a 10-ft bump-out with a row of new windows and a dining area, cabinets in pale mint green with matte black pulls, creamy quartzite-look quartz counters, large-format light stone-look porcelain tile flooring through the old and new space and a flush drum fixture and under-cabinet lights. Work included design and permit drawings, framing and roof tie-in, plus the new kitchen.

AfterKitchen Additions in a postwar bi-level, Villa Park
The site: a postwar bi-level in Villa Park. Before: original birch cabinets painted white decades ago, sagging doors, chrome pulls, laminate with an aluminum edge band and a round fluorescent ceiling ring. What bothered the owners most: a small, dark kitchen with no room for a table. Finished kitchen: the kitchen extended by a 10-ft bump-out with a row of new windows and a dining area, cabinets in deep olive with polished nickel pulls, warm walnut butcher block counters, light oak hardwood flooring through the old and new space and two glass pendants and recessed lights. On site this meant design and permit drawings, permits and plan review, plus the new kitchen.

Kitchen Additions questions from Oak Brook homeowners
Can I stay in the house during construction?
Usually. The time without a working kitchen is mostly at the end, when the old and new spaces are joined.
Will the addition match the rest of the house?
That's the goal. We match brick or siding, roof pitch, windows and trim, and plan the interior so floors and ceilings line up.
Does a bump-out need a foundation?
Most do. A small cantilevered bump-out can sometimes be supported by the floor framing, depending on joist direction, size and code. We'll tell you which applies.
Will the addition change my property taxes?
Usually some, since the house gets larger. The township assessor is the right place to ask how much.
Will my furnace and air conditioner handle the extra space?
Sometimes. We check the system's capacity; if it can't take the added area, we add a separate heating and cooling solution for the addition.
Do I need a Oak Brook-registered contractor for kitchen addition?
Oak Brook does not require contractor registration; no village-specific requirements for residential alterations. We take care of that before work starts.
Oak Brook plumbing code: who can do the plumbing for kitchen addition?
Current Illinois plumbing license (055 and 058) or current City of Chicago license; other municipalities' business licenses not acceptable. Our plumbing connections are made by licensed plumbers.
Oak Brook building permit for kitchen addition: where do I apply?
Permits go through Development Services (Building), phone (630) 368-5101. When your scope needs one, we prepare the application and schedule the inspections.
What does Oak Brook ask for on electrical work?
Current license from a testing jurisdiction, or current ICC electrician certification for the scope; other municipalities' business licenses not accepted. New circuits and wiring are done by licensed electricians.
Do I need a permit for kitchen addition in Oak Brook?
It depends on the scope. Oak Brook's rule in short: Village publishes a Residential Permit Requirement Listing; its Residential Alteration category requires contract/scope of work, architectural plans and plat of survey. We handle the permit when one is needed with Development Services (Building).
