Additions
Make more room for the way your family lives without leaving the home you already know. We plan custom additions around your property, manage required permits, and work to connect the new space naturally with your existing home.
A home can be a great fit when you first move in, then gradually start feeling smaller as life changes. A growing family may need another room. Working from home can create a need for dedicated space, or you may simply want more room to live comfortably without rearranging the same limited square footage again and again. When the location and character of your current home still work for you, moving may feel like an unnecessary answer to a space problem.
Living with too little room can affect more than storage. Crowded layouts can make daily routines frustrating, limit how rooms are used, and leave family members competing for the same areas. Relocating comes with its own major decisions and expenses, especially when you would rather stay where you are. A thoughtfully planned addition offers another path: change the house to better support the life happening inside it.
Monhec Construction provides residential home addition services for homeowners in Des Moines, IA, and surrounding areas. As a home addition contractor, we focus on creating new space that works with the existing structure rather than feeling disconnected from it. Our team brings over 40 years of construction experience to the work, and we are fully licensed and insured and EPA Lead-Certified.
The process starts with a free in-home consultation. We visit your property, listen to what you want from the additional space, and look at the existing home so the conversation is grounded in your actual needs. When building or construction permits are required, we handle them on your behalf. Our approach is centered on careful planning, respect for your property, and the goal of giving you additional room that feels like a natural part of your home.
If your current square footage is holding your household back, tell us how you would like your home to change. We can start with a conversation about the space you need and the possibilities for adding it.

Good home additions begin with a clear reason for adding space. Maybe your household has grown since you purchased the property, or the way you use your home has changed. Instead of starting with a one-size-fits-all idea, we want to understand what is missing from your current layout and how additional square footage could make daily life easier.
That homeowner-first planning is especially important with room additions because the new construction needs to relate to an existing structure. An addition should not feel like an afterthought. We consider the current property as we discuss the new space, with the goal of integrating the extension into the home and creating an area that serves a clear purpose.
As a home addition builder, Monhec Construction also understands that the physical construction is only one part of the project. Permit requirements can create another task for homeowners to navigate, so we handle required building and construction permits on their behalf. That allows you to focus more of your attention on how you want the finished space to function.
Our approach to custom home additions also reflects how seriously we take working on someone else’s property. We know construction happens where you live, so we approach the job site with the consideration we would expect in our own homes. Customer satisfaction stays at the center of the work, from the initial discussion through the finished addition.
Homeowners comparing contractors for home additions should also look beyond the size of the proposed extension. Experience, communication, permit support, workmanship, and how the contractor approaches the existing home all matter. Monhec Construction brings more than four decades of construction experience to those considerations.
Key benefits of our addition work include:
A well-planned addition can also help homeowners get more from a property they already enjoy. Rather than changing addresses because the existing floor plan has become restrictive, you can explore ways to expand the footprint and create room for new priorities.
The exact purpose of that space will differ from household to household, which is why we do not assume every addition should look or function the same way. Our job is to listen first, understand what you want to accomplish, and use that information to guide the construction conversation.
Craftsmanship warranties are available, with coverage ranging from 20 years to a lifetime depending on the project. We can explain what applies to your specific work rather than making a blanket warranty promise that may not fit every project.
For homeowners looking at home addition companies, that combination of practical support and respect for the property can make a meaningful difference. The goal is not simply to build more square footage. It is to give your household useful space that makes staying in your current home a more practical option.
You do not necessarily need a different address when the real problem is that your current home needs more space. A carefully planned addition can provide room for changing family needs while allowing you to remain in a property you already enjoy. We start by listening to what is missing from your current layout and discussing how new square footage could address it. From there, we consider how the added area can connect with the existing structure and support everyday use. Required building and construction permits are handled on your behalf when they apply to the project.
Monhec Construction brings over 40 years of experience to residential construction while treating your property with the care we would expect at our own homes. Your free in-home consultation gives us a chance to see the property firsthand and gives you room to explain what you want to accomplish. Depending on the size of the project, same-day estimates may be available, and craftsmanship warranties ranging from 20 years to a lifetime are available depending on the work. We serve residential homeowners throughout Des Moines and surrounding areas, helping families explore practical alternatives to moving when their homes no longer provide enough room. Start by telling us how your space needs to change and choose Monhec Construction when you need a trustworthy home addition contractor in Des Moines, IA.
Start by thinking about why your existing home no longer provides enough space and what you want the new area to accomplish. We offer a free in-home consultation so we can see the property, hear your ideas, and discuss your goals in the context of your current layout. This gives both you and our team a clearer starting point before moving further into the home addition project.
Integrating the newly built space with the existing structure is an important part of our approach to home additions. We look at the current property and discuss how the new area will be used rather than treating it as an isolated project. The goal is to create additional square footage that feels purposeful and connected to the home you already have.
No. When building or construction permits are required for your addition, Monhec Construction handles those permits on your behalf. Permit requirements can add another administrative task to a significant home project, so taking care of that part of the process allows you to spend more time focusing on the space itself and how you want it to serve your household.
Yes. Craftsmanship warranties are available for our work, with coverage ranging from 20 years to a lifetime depending on the project. Because the applicable coverage can vary, we do not assume that every addition receives the same warranty. We can discuss the craftsmanship warranty relevant to your project as part of the planning conversation so you know what applies.
For homeowners who like their current property but need additional square footage, an addition can provide another option to consider instead of relocating. Growing families, changing routines, and new space requirements can all make a once-comfortable floor plan feel restrictive. Custom home additions allow you to explore expanding the property around those needs while remaining in the home you already know.
