Expand Your Home Without Leaving the Neighborhood You Love
When you need more space but love where you live, a thoughtfully designed home addition is the smart solution. Whether you’re adding a private master suite, expanding your kitchen, building a home office, or creating a second story, A.W. Viohl Contracting designs additions that feel original to your home while giving you the room your life requires. Homeowners throughout Wilmington, Greenville, Hockessin, West Chester, Haverford, and surrounding communities trust us to create seamless expansions that enhance comfort, functionality, and long-term value.
Designed to Look Like It Was Always There
The best additions don’t look like add-ons — they look like they’ve always belonged. Every project begins with careful planning to ensure the new space integrates naturally with your home’s architecture, materials, and flow. From structural engineering and foundation work to matching finishes and coordinating rooflines, we manage every detail so your addition blends beautifully inside and out.
Since 2008, Andrew Viohl has helped homeowners throughout northern Delaware and southeastern Pennsylvania expand their homes with craftsmanship and attention to detail that stand the test of time. As a Wilmington native, he understands local building styles, permitting requirements, and the level of quality homeowners expect.
Add Space That Fits Your Life
Every family’s needs are different, which is why we design additions around how you actually live. Some homeowners want to expand their first floor to create open kitchens, larger family rooms, or new living areas that make everyday life easier. Others choose to build upward with second story additions that add bedrooms, bathrooms, or private retreats without sacrificing yard space. Smaller bump-outs can transform a kitchen, bathroom, or bedroom by adding just the right amount of square footage where it matters most. We also build garage additions, convert underused spaces into comfortable living areas, and create in-law suites or guest quarters that provide privacy and flexibility.
No matter the scope, we focus on creating spaces that feel cohesive, functional, and thoughtfully designed.
Seamless Integration Inside and Out
What sets our additions apart is the attention given to transitions between old and new. We carefully match exterior materials, rooflines, window styles, and architectural details so the addition complements your home’s character. Inside, we coordinate trim, finishes, and layout flow to create a natural connection that feels intentional and refined.
