We know what you are really worried about
After doing this out here for 20 years, we can almost guess what is on your mind before you say it. The people in Grantsville who call us are nervous about the same handful of things. Here is what we hear, and exactly how we handle each one.
That fear is earned. Most of the horror stories out here start with a low bid and a pile of change orders. We put one honest, itemized price in writing before we start, and it does not move unless you change the plan.
A bad addition screams addition. We match the roofline, the siding, and the trim so the new space looks like it was always part of the house, inside and out.
We pull the permit, handle the inspections, and build it to code, so it is done right and it will not come back to bite you when you sell.
We seal the work off from the rest of the house, keep the dust down, give you a real schedule, and keep the job moving so you get your home back.
You have seen the half-finished jobs where the crew left to chase the next check. We are local, we finish what we start, and Danny and Trayson are on your job, not off starting three others.
What a home addition includes
You get one team for the whole addition, so nothing falls through the cracks between trades.
We lay out the new space, pull the Grantsville City building permit, and schedule every inspection so it is legal and done right.
We pour the footing and foundation, then frame the new walls and roof so the addition is solid and built to last.
We tie the new roof into the old one and match the siding, trim, and windows so the addition looks like it was always there.
Outlets, lighting, heat, and rough-in for a new bathroom, laundry, or wet bar, all tied cleanly into your home.
Insulated and sealed for our cold Tooele winters, then drywall, texture, and paint that matches the rest of the house.
Luxury vinyl plank, carpet, tile, trim, and doors, finished to feel like it was part of the home from day one.
Our specialty
Your family has outgrown the house, but you love your street and your low mortgage rate. An addition gives you the extra bedroom, bathroom, or office you need, without the cost and upheaval of buying a bigger home.
Why an addition
Most Tooele County families who want more space are weighing these three. Here is the honest comparison.
| Build an addition | Finish the basement | Move to a bigger home | |
|---|---|---|---|
| Cost per square foot | High | Lowest | Highest |
| Timeline | Several months | A few weeks | Months, plus a move |
| Adds bedrooms and a bath | Yes, on your main floor | Yes | Maybe |
| Keeps your home and rate | Yes | Yes | No |
| Disruption to your life | Some, mostly outside | Low, it stays downstairs | Very high |

Local addition experts
We have added onto homes all over Grantsville, so we know the houses here. Grantsville has been a farm town since it was settled back in 1850, and the horse property and larger lots at the edge of town leave plenty of room to spread out and add on the ground floor. In the older homes around the Main Street grid and the newer subdivisions on the west side of town, growing families often need one more bedroom or a real home office before they will make the long commute to the Salt Lake valley worth it. An addition lets them stay put and get the space they need.
We know what the Grantsville City building department looks for, and we pull the permit and schedule the inspections ourselves. We match the new roofline, siding, and trim to the existing house so it does not look tacked on. And when the budget is the question, we can point you to financing so you can spread the cost out. You are not handed off to a salesman here. You get Danny and Trayson, the two owners who are actually on your job.
Grantsville was laid out as a farm town, and the horse property and larger agricultural lots at the edge of town usually have the room to add on at ground level instead of building up. That is the easiest kind of addition to live with. We add a primary suite, a great room, or a mother-in-law wing off the existing house and tie it in so it reads like it was always there.
The older homes around the wide, tree-lined Main Street grid were not built for how families live now. Many have small bedrooms, one bathroom, and no real gathering space. We add on carefully here, matching the roofline, siding, and trim, and on the historic homes, some built from the local adobe brick this town is known for, we take care to protect the character that makes that part of Grantsville what it is.
The newer subdivisions on the west side of town, where most of Grantsville's recent growth has landed, sit on smaller lots. When there is not much room to spread out, we build up or bump out: a bonus room over the garage, an extra bedroom, or a home office, so a growing family can stay in the house they already like.
Grantsville is its own incorporated city and issues its own building permits, so an addition here goes through the Grantsville City building department, not the county. We have been through that process many times. We handle the plans, pull the permit, and schedule the footing, framing, and final inspections ourselves, so you are not the one chasing paperwork.
Nearby, we also finish basements in Grantsville. See everything we do on our main home additions page.
Why Upterra
Upterra Builders is not a big company with a sales office. Danny and Trayson run the jobs themselves, so the people who quote your project are the same people who finish it.
Danny and Trayson quote the work and stay on the job. No handoff to a project manager you have never met.
You get a real written estimate before the work starts. If the budget and the plan do not match, we tell you up front.
We work in Tooele, Stansbury Park, Grantsville, Erda, Stockton, and nearby. We know the local permit process.
Clean framing, straight tile, and a crew that treats your home like it is theirs. Homeowners tell us so.
Where we work
Upterra Builders is based in Tooele County and finishes basements and remodels homes across the whole valley.
