Add the space you need with a room built for comfort, function, and long-term value.
At Nenneman-Haus Construction, we build home additions that give you more space without the stress of moving. If your family needs an extra bedroom, a larger kitchen, a home office, a sunroom, or a full in-law suite, we can design and build an addition that fits your home and your goals. A well-built room addition should feel like it has always been part of the house. That is what we focus on from the start.
Home additions are one of the best ways to improve comfort, function, and long-term property value. Instead of dealing with the cost and hassle of buying a new home, many homeowners choose to expand the space they already love. We help you make that space work better for daily life while keeping the new construction practical, durable, and attractive.
We handle many types of custom home additions based on your layout, budget, and needs. Common projects include:
Every home addition project is different. Some homeowners need more square footage for a growing family. Others want better flow, more natural light, or a dedicated space for work, guests, or hobbies. We take the time to understand how you use your home so the finished addition solves a real problem and adds daily value.
We believe a successful room addition starts with good planning. We begin by learning what you want from the space, where the addition will connect to the existing structure, and what makes the most sense for your lot and budget. From there, we look at layout, structural needs, roofing lines, foundation requirements, window placement, insulation, and finish details.
As an experienced, veteran-owned construction company, we know that the details matter. We work to make sure the new space blends with the rest of your home as closely as possible. That includes matching exterior materials, tying in the roof correctly, aligning floor heights, and creating a smooth transition between old and new spaces.
During construction, we focus on workmanship, jobsite organization, and clear communication. Home additions involve many moving parts, including framing, roofing, siding, windows, electrical, plumbing, HVAC, insulation, drywall, flooring, trim, and paint. We manage the work in a logical order so your project keeps moving and the quality stays consistent.
The scope of a home addition depends on the type of space being built, but projects commonly include:
When needed, we can also help plan practical features like storage, closet space, bathroom layouts, traffic flow, and accessibility improvements. The goal is not just to add space, but to make the new square footage useful and comfortable every day.
A custom home addition can solve several problems at once. It can give your family room to grow, improve privacy, create better function, and increase resale appeal. Many homeowners also use additions to avoid the disruption of moving, especially when they already like their neighborhood, school district, or property.
Other key benefits include:
When an addition is designed well, it can make the entire house feel more balanced. A cramped layout can become open and functional. An underused backyard area can become a bright new living space. A small home can become a long-term home.
We approach every home expansion with a focus on durability and everyday comfort. That means paying attention to things like insulation, airflow, moisture control, structural integrity, and finish quality. These are the details that affect how the room feels years after the project is done.
We also understand that budget matters. Our payment terms are simple: 50% up front and 50% at completion. That straightforward approach helps homeowners plan ahead and understand what to expect. We believe in being clear about the work and the process from the beginning.

If you need more space and want a solution that adds comfort and value, contact Nenneman-Haus Construction today. Call us at (712) 621-7304 or reach out through our website form to discuss your home addition project. We are here to help you build the extra space your home needs.
We start with a phone call or website form, then meet at your home to review your space, goals, budget, and structural needs. Within about 1 to 2 weeks, we outline a clear addition plan, project scope, and pricing so you know exactly what to expect before we build.
Once approved, we handle pre-construction planning, including measurements, framing details, material selections, and permit coordination. Before work starts, we lock in a realistic schedule, protect existing areas of your home, and keep you updated so the project moves smoothly.
Our team completes the addition with close attention to structure, weather protection, insulation, and finish quality, while keeping the jobsite clean and communication consistent. After construction, we walk the space with you, review every detail, and finish only when the new room is ready for daily use.

“I was very happy with Kyle and Joe at Nenneman-Haus Construction. They came up right away after the storm and fixed my roof. Thank You.”
“Joe Nenneman-Haus Construction did an excellent job with the remodel of my home. His communication and quality of work is excellent. Once The walls were exposed, There was major issues that needed to be addressed and he was able to handle it with ease. I was very pleased with Joe and his team.”
“After having a very poor experience with another local construction company, I was honestly nervous moving forward with our building plans. I recently spoke with Kyle at Nenneman-Haus Construction out of Stanton, Iowa, and immediately felt more comfortable. He answered all of my questions in detail, explained their process clearly, and was very transparent about timelines, labor, materials, estimates, and the fact that there were no hidden costs, which was so important to me. What stood out most was that their estimates and timelines are written out and completely transparent, which gave me a lot more confidence moving forward. They complete the majority of their projects with their own local crew and prioritize communication throughout the process. Kyle was patient, easy to talk to, kind, and never made me feel rushed or brushed off. They also offer free estimates and were willing to come out and look at the project, which I really appreciated. Good communication and transparency matter so much when making a large investment, and Kyle definitely gave me confidence moving forward. Although I haven’t officially committed to building yet, Nenneman-Haus Construction will definitely be considered when the time comes. I truly appreciate the time he took to walk me through everything.”
