More house, same neighborhood.
Moving costs more than building. NXT Build adds master suites, sunrooms, second stories, and garage additions to existing Dubuque homes with the same level of finish we bring to new builds from the ground up.
Owner Collin walks your property first. You get a scope of work and a fixed-price written quote before any permits are pulled. No open-ended time-and-materials contracts on your primary residence.
NXT Build is licensed and insured in Iowa. We handle the full scope: design-assist, permitting, foundation work if needed, framing, roofing tie-ins, drywall, and finish work. See examples in our gallery or send us a note about your Dubuque project.
The part of an addition that separates a clean job from a sloppy one is the connection point where the new structure meets the old house. That is where the roof ties in, where the foundation has to match the existing footing, and where the new framing has to line up with walls that may have settled over the years. Older Dubuque homes are rarely perfectly square, so we measure the existing structure carefully before framing and plan the tie-in so the finished addition reads as part of the original house instead of an obvious bolt-on.
Because you are living in the house while we build, we also plan the work to keep your home usable. We seal off the construction zone, protect the flooring on the routes we use, and keep the site clean at the end of each day. One of the reviews on our page mentions that our crew cleans up the work area and works without complaining or making excuses. On an addition attached to your primary residence, that discipline is not a nice-to-have. It is the difference between a hard few weeks and a genuinely stressful few months.
Addition types we build in Dubuque.
Every scope is different. This is what the calls from Dubuque County homeowners tend to look like.
Master suite additions.
A first-floor or second-floor primary bedroom and bathroom addition. Typically 300 to 600 square feet added to the rear or side of the home. We handle the foundation bump-out, framing, roofline integration, rough plumbing and electrical, insulation, drywall, and finish work including tile, cabinetry, and trim.
Second-story additions.
Adding a full or partial second story to a ranch-style home in Dubuque. We evaluate the existing foundation and load-bearing walls before quoting. The existing roof comes off, the first-floor structure is reinforced where needed, and the new floor system, framing, and roof are built from scratch. One of the most disruptive projects in scope, but also one of the highest value-per-dollar additions available.
Sunrooms and three-season rooms.
A permanent structural addition with large windows or a glass-and-frame system, built on a proper foundation with conditioned or three-season intent. We do not install prefab sunroom kits. The framing and foundation work are done the same way as any other addition. If you want it to last in a Dubuque County freeze-thaw climate, it needs to be built to that standard.
Garage additions and attached garages.
Attaching a new garage to an existing Dubuque home or expanding an undersized attached garage. We handle the site work, slab or frost-wall foundation, framing, overhead door rough opening, roofline tie-in, and interior finish. Includes coordinating the new access door from the house with your existing layout so the connection point reads clean from the inside.
How it works when you call NXT Build.
Home additions involve more coordination with the existing structure than new construction. Here is the order of operations from your first call to finished space.
Site walk and scope conversation
Collin visits your Dubuque property. You walk the existing house together and talk through what you want the addition to accomplish. He measures, checks the existing foundation and structure at the connection point, and asks the questions that affect cost: is there a basement below the addition footprint? Where does the roof tie in? What is the existing electrical and plumbing situation? This visit is free.
Fixed-price written quote
After the site walk you receive a written fixed-price quote with a full scope of work. The price is firm barring genuine unknown conditions discovered once walls are opened. We do not start projects with a ballpark and bill the rest as “unforeseen.” If the scope is complex enough to benefit from a designer or engineer on the front end, we say so and help you find the right person before quoting.
Permitting and scheduling
Additions in Dubuque County require building permits. We pull the permits. We give you a realistic start date and a build schedule when you sign the contract so you know how long your household will have a construction zone attached to it. Contact us to get the process started.
Build and final walkthrough
The addition goes up on schedule. Inspections happen at the required phases. When we are done, we walk through the finished space with you, address any punch-list items, and you get the certificate of occupancy. View our past work to see what the finished product looks like across different addition types.
