Every project we take on is backed by craftsmanship, transparency, and respect for your home and budget.
If your family is growing, you need more functional space, or you’d simply like to boost your home’s value, home additions are a smarter alternative to moving. At TJ Builders & Developers, we specialize in designing and building custom additions for homes in Lakewood, Crystal Lake, Schaumburg, and nearby areas. Whether you want a larger kitchen, a new family room, garage expansion, or second-story addition, we’re here to help you expand your square footage without losing character or style.
A home addition means physically expanding your house’s footprint or adding vertical space to create new rooms or extend existing ones. This could be a bump-out, full second-story addition, sunroom, master suite, or extending the living room or kitchen. Our services include everything from planning and permits to construction, finishing, and seamless integration with the existing structure. We ensure your addition looks and feels like it’s always been part of your home.
We deliver thoughtful, high-quality additions that iron out space issues and elevate your home. Here are key services we offer:
Each project is handled by experienced professionals familiar with zoning, permits, architecture, and local building codes to make the process smooth and compliant.
Wondering whether you should expand or renovate internally? Here are five common indicators your home could benefit from an addition:
If any of these ring true, it’s a good time to explore addition options with an experienced contractor.
Choosing the right path depends on your goals, budget, and property. Here’s how to evaluate your options:
Remodel only — Best if you aren’t increasing footprint; working within existing walls.
Addition (horizontal or vertical) — Ideal when you need notable extra square footage, new rooms, or improved flow.
New build elsewhere — More expensive and may involve moving; addition is often more economical and customized.
We believe in a clear, step-by-step approach to make sure your addition goes smoothly:
Discuss your space needs, style, budget, and timeline.
Create architectural drawings, surveys, elevation plans, and submit for all local approvals. (Lakewood, Crystal Lake, and Schaumburg require stamped plans and inspections.)
Plumbing, HVAC, electrical, windows, doors, drywall, siding, flooring, paint, and trim to match the rest of the home.
Complete quality check, ensure compliance with all codes, and provide a final handoff.
To help you imagine what’s possible, here are two example addition options we offer and how they benefit homeowners, based on common local needs and competitor services:
