Living space and kitchen expansions
Create room to gather, cook or spend time together. We consider the connection to existing rooms, circulation, windows and storage as part of the scope.
Sehnco Builders · Pennsylvania
Home additions in Montgomery County.
More room, built to feel like it has always belonged. Sehnco Builders plans and builds home additions throughout Montgomery County and surrounding areas, with reliable communication and precision craftsmanship.
Reliability and precision
Make room for the way you live.
If you love your location but need more space, an addition can help your home fit your next chapter. A larger kitchen, a family room or additional living space should work naturally with the rooms you already have. We consider how people will move between the new and existing spaces, how daylight enters the home, and how the exterior comes together.
Our family owned team serves homeowners in Lafayette Hill, Blue Bell, Ambler, Plymouth Meeting and Villanova, as well as the surrounding communities listed in our service area guide. Michael and Colin Sehn bring decades of hands on experience and a focus on reliable craftsmanship to the work.

Project scope
The work, down to the details.
Structure and exterior
Foundations, framing, roofing, siding, windows and doors all contribute to an addition that feels integrated with the original home.
Systems and interior finishes
Electrical and plumbing work, flooring, trim and finish carpentry bring the new space into everyday use. We coordinate these details with the overall build.
Before you build
A clear scope before construction.
The right addition depends on your property, the existing structure and the space you want to create. At the outset, discuss the footprint, access to the work area, budget priorities and how construction could affect daily routines. Zoning, setbacks, structural design and any required approvals need to be reviewed for the specific property before work begins.
Budget and timing
An estimate built around your home.
Size is only one part of an addition estimate. Foundation conditions, structural connections, roofing, utility changes and finish selections also affect cost and timing. Share any drawings you have and your preferred start window so we can discuss the next steps for your project.
Start with your town, the changes you have in mind and your preferred timing. We typically respond to inquiries within two business days.
