Home Additions Experts
Expert Home Additions Services
GS Construction & Remodeling specializes in professional Home Additions. As a father-son team, we bring decades of combined experience to every project.
From the first walkthrough to the last punch-list item, Greg or Patryk runs your Home Additions project themselves. That means a scope written out line by line instead of one number, permits pulled and handled with your village, and the same faces on site rather than a crew you've never met.

- On-site supervision for every project
- Transparent pricing with no surprises
- Quality craftsmanship guaranteed
"Your Home Additions project deserves the best—we deliver it."

Deer Park permits & building codes for home additions
The Village of Deer Park issues building permits through its Building Department at Village Hall on Cuba Road: a completed application is dropped off or mailed in with a permit deposit, and the building inspector determines the required plans and submittals for each project. It is a small village where permitting runs on direct coordination with village staff rather than a big-city portal. GS Construction manages the full permit process for Deer Park homeowners, from application through final inspection.
How your Deer Park project runs
ProcessThe same six stages on every job — free in-home estimate through warranty.
Free in-home estimate
Greg or Patryk — the owners, not a salesperson — walk your space, take real measurements, and give you honest feedback on what your budget buys.
Itemized scope & contract
Labor, materials, demolition and disposal priced line by line, not one mystery number. Payment terms and warranty are in the written contract.
Design & selections
Bring your own designer, use our architects and designers, or choose everything yourself. Selections are scheduled ahead so lead times never stall the site.
Permits & scheduling
We pull and manage building, plumbing and electrical permits with your village — typically 1–2 weeks — and hand you a written schedule before demo day.
The build, owner-supervised
Long-standing trade partners working in sequence under daily owner supervision. Your client portal shows the schedule, change orders and current balance.
Walkthrough & warranty
We walk the finished job together, close out every punch-list item, hand over manufacturer paperwork, and your written workmanship warranty starts. Our commitment never expires.
Testimonials
Your Neighbours in Deer Park Love Us
Real reviews from homeowners. Ask us for live phone references.
We learned of GS Construction through acquaintances who had hired them for two kitchen remodels, and subsequently hired them for our new hardwood oak floors, kitchen remodel, and conversion of a half bath to a full bath. Greg and Patryk were fantastic and so was everyone on their team. Incredible workmanship, respect, and attention to detail. Every project will have a few unexpected curveballs, but not every project will have a contractor who deals with them so seamlessly. We were proactively told of any timeline adjustments or accelerations and always kept in the loop. The level of communication was fantastic. We are extremely happy with our remodeled home and would definitely hire GS Construction again!
