Custom home builder in Long Grove, Iowa.

Long Grove is in the rural northeast corner of Scott County. Custom homes on acreage, barndominiums, and post-frame ag buildings for the surrounding farms.

Whether you need a new roof on the house or a whole new house, the call goes to the same place. In Long Grove, NXT Build takes on custom homes, additions, barndominiums, post-frame buildings, roofing, and framing for homeowners and light commercial owners, with one crew doing the work.

Collin spent eleven years running post-frame builds for a contractor in eastern Iowa before starting NXT Build LLC in 2024. He knew the work could be done better. Cleaner job sites. Tighter schedules. Honest answers about cost and timeline. One person who answers the phone and stays on the project from beginning to end.

Why Long Grove customers choose NXT Build.

The customers we work with in Long Grove tell us the same thing again and again. They have called other contractors. They got sold by a salesperson, handed off to a project manager, and then handed off to a crew that did not entirely know what was being built. They paid for the privilege.

At NXT Build, all three of those jobs are Collin. He sells the project because he is going to build it. He runs the schedule because he is on the site every day. He hands you the keys because he framed the roof. One phone number. One email address. One point of accountability.

The way the build runs.

On a Long Grove build, the order of work stays the same. Collin walks the site with you first, at no cost, and asks what you need the building to do. The plan and a fixed-price written quote come next, and nothing gets signed until you have read both. After you sign, we handle the permits and inspections, set the foundation, and frame. The last step is a walk-through together before you take the keys.

A barndominium fits Long Grove acreage well. It puts the living space and a working shop under one post-frame roof and on one slab. The shell is the kind of building Collin put up for eleven years before starting NXT Build. The inside finishes like any custom home, with drywall, cabinets, and trim.

The slab is where a barndominium gets decided. Plumbing for the kitchen, the bathrooms, and the laundry has to be roughed in before the concrete goes down, so the floor plan is final before we pour. Moving a bathroom later means a saw and a jackhammer. We go over the layout on paper with you until you are sure of it.

Living space inside a steel-sided building needs real attention to moisture. In an Iowa winter, warm air from the house side meets cold steel, and without the right insulation and vapor control you get condensation dripping off the ceiling. We detail the walls and ceiling on the living side the way we would on a stick-built home. The shop side stays separated, so the smell of a truck or a welder stays out of the bedrooms.

Getting to Long Grove from Zwingle means crossing the Wapsipinicon into Scott County, toward the south end of the area we cover. Because the drive is longer, we time material deliveries so the crew is already on site when the lumber truck and the steel package pull in. Nothing sits in the yard waiting on us, and every bundle gets set down where it will be used.

Plenty of owners out here still want a traditional house with a separate post-frame building out back. That works too. The two buildings can share one driveway and one electric service, which keeps the site work in a single quote, and the ag building can be sized for equipment without changing anything about the house.
