Adding Space That Feels Like Home

Home Additions in Decorah, Iowa

When your family outgrows the bedrooms you have or you need a main-floor office that does not sit in the corner of the dining room, an addition gives you the space without the cost and upheaval of moving. Homes in Decorah often sit on lots with room to expand, and adding square footage can mean staying in the neighborhood and school district you already know. Farley Construction LLC designs and builds home additions that connect seamlessly to your existing structure and feel like they were always part of the house.

Home additions involve more than framing new walls. We match siding, roofline, and interior finishes so the transition between old and new is nearly invisible. Foundation work, structural ties, and weatherproofing are handled with the same care as a full new build, and we coordinate inspections and utilities to keep the project moving without leaving your home torn open longer than necessary.

Blending New Space With Existing Structure

Home addition work in Decorah starts with evaluating how the new space will tie into your foundation, roof, and mechanical systems. We pull permits, excavate for footings, pour concrete, and frame walls that match the height and span of the original structure. Siding, trim, and roofing materials are sourced to match or complement what is already there, and we take care to protect your landscaping and existing exterior finishes during construction.

When the addition is finished, you walk through rooms with level floors, square corners, and trim that aligns with the rest of the house. Doors swing freely, windows operate smoothly, and heating or cooling reaches the new space without overworking your system. The roofline sheds water correctly, and flashing prevents leaks where old and new sections meet.

We manage subcontractors for electrical, plumbing, and HVAC so the work stays on schedule and meets code. Interior finishes are installed with the same attention to detail as structural components, and we clean up daily so your home stays livable during construction. The project timeline reflects realistic expectations, and we communicate any adjustments as soon as they come up.

You Probably Have a Few Questions

Homeowners considering an addition often wonder how the process affects daily life, whether permits are required, and how we handle matching existing materials.

How long does a typical home addition take?
Most additions take two to four months depending on size and complexity. We provide a timeline before starting and keep you updated if weather or inspections cause delays.
Will you be able to match my siding and trim?
We source materials to match or closely complement your existing siding, trim, and roofing. If exact matches are unavailable, we recommend alternatives that blend visually and perform well.
What permits are required for a home addition in Decorah?
You need a building permit and inspections for foundation, framing, electrical, plumbing, and final occupancy. We pull permits and schedule inspections as part of the project.
Can you extend my existing HVAC system into the addition?
In most cases, yes, but it depends on your system's capacity and the size of the addition. We work with HVAC contractors to evaluate load and recommend ductwork or upgrades if needed.
How do you protect the rest of my home during construction?
We use plastic sheeting, temporary doors, and protective coverings to contain dust and debris. Work areas are cleaned daily, and access points are secured at the end of each day.
