Home Addition Construction in Iowa City & Cedar Rapids

Adding onto an existing home is more involved than starting from scratch. The new space has to work with your current structure, match the existing aesthetic, and meet all local permitting requirements. We handle every part of that process.

Before any work begins, we assess the existing structure, walk through your goals, and outline a realistic plan. We pull the permits, manage the subcontractors, and make sure the addition blends into your home rather than sticking out as an obvious add-on. The result is additional square footage that adds long-term value and actually feels like part of your home.

Garage Builder

We build both attached and detached garages throughout eastern Iowa. Whether you need a basic two-car garage, additional storage, a dedicated workshop space, or a combination of all three, we’ll design something that works for your property and matches the existing style of your home.

We also handle the site prep, concrete work, and electrical rough-in, so the whole project is coordinated from the start.

Deck Builder

A well-built deck extends your usable living space and adds real value to your property. We design and build custom decks using materials suited to your budget and maintenance preferences, including pressure-treated lumber, composite decking, and hardwoods.

We’ll help you think through the layout, including stairs, railing options, built-in seating, and how the deck connects to your home’s interior flow.

Patio Builder

Patios give you a durable, low-maintenance outdoor space for entertaining, relaxing, or simply spending time outside. We work with concrete, pavers, natural stone, and other materials depending on the look you want and how you plan to use the space.

Every patio we build is graded properly for drainage and built to last through Iowa’s freeze-thaw cycles.

Accessory Building Construction

Not every structure on your property is a garage or a deck. Casper Builders also constructs accessory buildings, including guest houses, accessory dwelling units (ADUs), storage sheds, barns, and multi-use outbuildings.

These projects come with their own planning considerations. Zoning rules vary by city and county, and setback requirements, lot coverage limits, and utility connections all need to be factored in early. We help you work through those details before breaking ground so there are no surprises mid-project.

Whether you need a separate space for extended family, a rental unit, or a large storage structure, we’ll build it to the same standard as everything else we do.

Home Renovations and Remodeling

Sometimes the best home isn’t a new one, it’s the one you’re already in, updated to fit how you live now. Whether you’re looking for a custom home renovation in Iowa or a targeted room update, Casper Builders handles remodeling projects of all sizes, from single-room updates to whole-home renovations.

As an experienced custom home remodeler, we focus on structural integrity, functional layout improvements, and finishes that will hold up over time. Our team is experienced in working around occupied homes, managing project phases to keep disruption manageable, and delivering results that feel like a natural extension of your home rather than a hasty fix.

Kitchen Remodeling

The kitchen is the most-used room in most homes, and it shows when the layout doesn’t work. We redesign kitchens with an eye toward how you actually cook and move through the space, not just how it photographs.

That means thinking through cabinet placement, counter space, appliance positioning, lighting, and traffic flow together rather than treating each one as a separate decision. We work with a range of cabinet styles, countertop materials, and fixture options to find the right balance between aesthetics and everyday function.

Bathroom Remodeling

A bathroom remodel can range from a simple fixture update to a full gut-and-rebuild. We handle both. Common projects include converting tub-only bathrooms to walk-in showers, updating vanities and plumbing fixtures, retiling floors and shower surrounds, and improving ventilation and lighting.

We keep practicality at the center of every bathroom project. Good design here means a space that’s easy to clean, comfortable to use daily, and built with materials that won’t deteriorate quickly in a high-moisture environment.

Why Choose Casper Builders as Your Custom Home Builders

We’re a local company, and our reputation depends on the quality of what we leave behind. Here’s what that means in practice:

• Experienced in project management. We coordinate every trade and keep your project moving on schedule. You won’t be the one chasing down subcontractors.
• Honest communication. If something changes, we will tell you immediately. No surprises on your final invoice.
• Craftsmanship that holds up. We build to last, not to look good at the final walkthrough and fall apart two winters later.
• Full-service capability. From permits to punch lists, we handle it. You don’t need to manage multiple contractors or figure out what comes next.
• Local knowledge. We know Iowa’s building codes, climate requirements, and what local inspectors expect. That experience saves time and avoids costly do-overs.
