Home Additions & Accessory Dwelling Units
Need more space? FK Builders designs and builds room additions and accessory dwelling units (ADUs) that fit your property and your home.
We take care of design, permitting, foundations, framing and finishes, and tie new construction into your existing structure.
An ADU can house family, guests or a rental; an addition can give you the room you need without moving.

“Excellent results for sunroom addition! Very meticulous with work, reliable, and honest! You couldn’t select a better contractor!”
“We called F.K. Builders and talked with Fred about a house in Maryville we wanted him to inspect and advise us on before making the purchase. We spoke about putting a addition on one end of the house and a few other upgrades. Fred was very knowledgeable and professional. If we purchase the home F.K. Builder's will be who will call. Highly recommend.”
“Fred proved dependable and honest during the installation of hardware for my home's construction. His craftsmanship exceeded expectations, showcasing his capabilities that reach far beyond his specific tasks.”
We Understand What You're Up Against
Too many owners hand over a deposit and end up with a half-finished project, a contractor who stopped returning calls, or a red tag from the inspector.
That's not how we work. FK Builders manages every trade and every inspection ourselves, so your project gets done right, and gets done.
