A well-built porch or deck adds living space, value, and a place to enjoy Chicago’s beautiful summers and crisp falls. At Pegasus Construction, we design and build custom decks and the rear porch systems Chicago is known for — engineered for our freeze-thaw climate and built strictly to Chicago code. From low-maintenance composite decks to classic wood and code-compliant multi-story porches, we deliver outdoor spaces that are as durable as they are beautiful.

Outdoor Living, Designed & Built Right
Your Porch & Deck Project, Handled End to End
We design and build your porch or deck end to end — from footings set below the frost line to framing, decking, railings, and stairs. Every build is engineered for Chicago’s freeze-thaw ground movement and finished with craftsmanship that lasts.
As a full design-build contractor, we navigate Chicago’s strict porch ordinance and permitting for you, and can integrate your new outdoor space with siding, concrete, and exterior work for a cohesive result.
Built for How Chicago Lives Outdoors
We design and build the porch and deck options that perform best in Chicago’s climate.
Composite Decking
Low-maintenance composite (like Trex) that resists rot, fading, and splinters — ideal for Chicago’s wet springs and snowy winters, with decades of easy enjoyment.
Natural Wood Decks
Classic cedar and pressure-treated wood decks with warm, timeless character, built and sealed to handle the Midwest seasons.
Chicago Porch Systems
Code-compliant multi-story rear porches — the Chicago classic — engineered and permitted to the city’s strict porch standards.
Porches & Decks Built for Chicago's Homes & Neighborhoods
The Chicago Rear Porch, Done Right
The multi-story rear porch is a Chicago icon — on two-flats and greystones across Logan Square, Avondale, and Humboldt Park, and on bungalows throughout the Northwest Side. After the city’s strengthened porch ordinance, these structures must meet strict engineering and code standards. We design and build them to last, safely and to spec.
Built for Freeze-Thaw & Four Seasons
Chicago’s freeze-thaw cycles heave improperly set footings and punish unsealed wood. We set footings below the frost line and select materials — composite, sealed cedar, treated lumber — that hold up through deep winters, wet springs, and humid summers.
Permits & Chicago Porch Code
Chicago has some of the most demanding porch and deck codes in the country. We handle permitting and inspections with the Chicago Department of Buildings and build to the city’s load and construction requirements — so your structure is safe, legal, and built to endure.
Neighborhoods We Serve
From Lincoln Park, Lakeview, and Roscoe Village to Bucktown, Wicker Park, and Irving Park — plus suburbs like Oak Park, Evanston, Skokie, Park Ridge, and Niles — Pegasus Construction is the porch and deck builder Chicago homeowners trust.

Porch & Deck FAQs
Should I choose composite or wood decking?
Composite (like Trex) is low-maintenance and resists rot, fading, and splinters — great for Chicago’s wet, snowy climate. Natural wood offers classic warmth at a lower upfront cost but needs regular sealing. We’ll help you choose.
Do you build code-compliant Chicago rear porches?
Yes — multi-story rear porch systems are a specialty. We engineer and build them to Chicago’s strict porch ordinance, with permits and inspections handled.
Do you handle permits?
Always. Chicago’s porch and deck codes are strict, so we manage permitting and inspections with the Chicago Department of Buildings as part of every build.
How long does a porch or deck build take?
Most projects take one to a few weeks depending on size, design, and permitting. We give you a clear schedule before starting.
How do you keep decks from rotting or heaving in Chicago winters?
We set footings below the frost line to resist freeze-thaw heave and select rot-resistant materials and finishes built for the Midwest.
Can I get a custom design?
Absolutely — we design porches and decks around how you want to live outdoors, your home’s style, and your budget.
What affects the cost?
Size, materials, height and stairs, railings, and code requirements all factor in. We provide a clear, itemized estimate.
