More Space, Seamlessly Done

At Wrona Construction, our home additions service is designed to seamlessly expand your living space while maintaining the integrity and style of your existing home. We specialize in creating custom additions that enhance functionality and add significant value to your property. From initial concept through final inspection, our team works closely with you to ensure every detail aligns with your vision and needs. Home additions in Montgomery County and on the Main Line require more than just skilled construction — they require local knowledge of zoning requirements, municipal permit processes, and the architectural character that defines neighborhoods like Ardmore, Bryn Mawr, and Haverford. Our team has navigated these requirements for years, so your project moves forward without delays or missteps. With a commitment to high-quality craftsmanship, transparent communication, and timely execution, we transform your home to better suit your lifestyle. Whether you're adding a new bedroom, building a sunroom, finishing a second story, or creating an in-law suite, Wrona Construction delivers exceptional results tailored to your unique requirements.

Our Process

How We Build Your Remodel

01

Planning & Design

We meet at your home, assess your property, and develop a detailed design plan. For additions, this phase includes architectural planning, zoning review, and a full permit strategy specific to Montgomery County municipalities. We coordinate with engineers as needed before any ground is broken.

02

Site Prep & Demo

All permits are pulled and approved before work begins. We prepare the site — whether that means foundation excavation, wall opening, or roof modification — with careful attention to protecting your existing home and minimizing disruption to your daily life.

03

Construction & Installation

Our crew builds the addition from the ground up — foundation, framing, roofing, windows, electrical, plumbing, HVAC, insulation, drywall, and finishes — all managed by one team under daily project oversight. Exterior materials are matched to your existing home for a seamless look.

04

Final Walkthrough

We schedule the final inspection with the municipality and walk every room with you before closeout. Any punch list items are resolved before we consider the project complete. Your certificate of occupancy is in hand before we leave.

FAQ

Common Questions

Do I need permits for a home addition in Montgomery County, PA?
Yes — virtually all home additions in Montgomery County require permits, including building, electrical, plumbing, and in some cases zoning approvals. The process varies by municipality, but typically involves submitting architectural drawings, a site plan, and an application to your local building department. Wrona Construction handles the full permit process for every addition project, so you don't have to navigate the paperwork yourself.
How long does a home addition take to complete?
Most home additions take 12 to 24 weeks from permit approval to final walkthrough, depending on the size and complexity of the project. Simple room additions or sunrooms may be on the shorter end of that range, while second-story additions or projects requiring foundation work typically run longer. We provide a detailed project schedule during the planning phase so you know what to expect.
How much does a home addition cost in Ardmore, PA?
Home addition costs on the Main Line typically range from $80,000 to $300,000+, depending on the size, type, and complexity of the project. A sunroom or basic room addition sits at the lower end; a full second-story addition or in-law suite with custom finishes trends toward the higher end. We provide a detailed estimate after an in-home consultation and site assessment.
What zoning approvals might be required for a home addition?
Zoning requirements vary by municipality, but common considerations include setback rules (how close the addition can be to property lines), lot coverage limits (what percentage of your lot can be covered by structures), and height restrictions. In some cases, a zoning variance or conditional use approval may be required. We review zoning requirements as part of the planning phase and advise you on what approvals are needed before any work begins.
Will a home addition match the look of my existing home?
Yes — matching the existing home is a core part of our design and construction process. We select exterior materials, window profiles, roofline details, and siding to integrate seamlessly with your home's existing character. Main Line homes have strong architectural identities, and we take that seriously. The goal is for the addition to look like it was always part of the original design.
