If you've been touring new construction in the southwest valley, you've probably run into Triad Springs — Lennar's community off Blue Diamond Road in the 89178 ZIP, near Mountain's Edge and a straight shot to the 215 Beltway. Its Carol floor plan is one of the most talked-about model homes in Southwest Las Vegas right now, and for a specific reason: it's a two-story that puts a full bedroom and bathroom on the main floor, which quietly solves the layout problem that a huge share of today's buyers are chasing — a place for aging parents, adult kids, long-term guests, or a real home office that isn't a converted upstairs bedroom.
This guide breaks down the Carol and the wider Triad Springs community using Lennar's published pricing plus live Multiple Listing Service data for the surrounding 89178 market, cross-checked against the roughly 9,600 closings our team has represented across the valley. You'll get the real specs and price, how the Carol's dollar-per-square-foot compares to what new homes in the area actually sold for, what the other Triad Springs collections offer, who the plan fits, and the one move that protects your money on any builder purchase.
The Carol is Lennar's 4-bedroom, 3-bath, 2,670-square-foot two-story plan at Triad Springs in Southwest Las Vegas (ZIP 89178), from $579,990. Its standout feature is a downstairs bedroom and full bath — ideal for guests, a home office, or multigenerational living. That base pencils to about $217 per square foot, below the $266 new homes in 89178 sold for over the last 180 days. Bring your own agent to the first visit.

What Is the Carol Model at Triad Springs?
The Carol is a two-story, single-family home of 2,670 square feet with 4 bedrooms and 3 bathrooms, built by Lennar at Triad Springs and priced from $579,990. What sets it apart from most two-story plans in its size and price class is the main-floor configuration: a bedroom and a full bathroom sit off the foyer, separate from the open-concept great room where the kitchen, dining, and living areas flow together. Upstairs, three more bedrooms wrap around a flexible loft, anchored by the owner's suite with a spa-style bathroom and a walk-in closet.
That downstairs bedroom-and-bath is the whole story. A lot of two-story homes in this bracket give you a powder room downstairs and stack every bedroom upstairs — which forces guests, live-in parents, or a home-office setup into the middle of the family's sleeping quarters. The Carol's ground-floor suite means a parent doesn't climb stairs, a guest gets privacy, and a remote worker gets a real door to close. In our experience, this exact layout is one of the most-requested features from Las Vegas buyers right now, and it's why the Carol draws the tour traffic it does.
Where Is Triad Springs in Southwest Las Vegas?
Triad Springs sits at 9686 Paradise Park Drive, Las Vegas, NV 89178 — in the southwest valley, off Blue Diamond Road, in the broader Enterprise/Mountain's Edge area. That location is a big part of the value. You're minutes from the 215 Beltway, which puts Harry Reid International Airport, the Strip, and Summerlin all roughly 20 minutes away, and you're close to the retail and dining along the Blue Diamond and Durango corridors — including the newer Town Square and UnCommons destinations to the east. Nearby Nathaniel Jones Park and the Mountain's Edge trail system give the area real outdoor recreation, not just rooftops.
According to Las Vegas REALTORS, the southwest and Enterprise submarkets consistently rank among the valley's highest-demand areas precisely because of this combination — new homes, Beltway access, and amenities in one place. For the wider picture of new construction in this quadrant, see our Southwest Las Vegas new-construction guide, and for the master plan next door, our Mountain's Edge community page breaks down the neighborhood in detail.
How Much Does the Carol Model Cost in 2026?
The Carol starts at $579,990, which for a 2,670-square-foot home works out to roughly $217 per square foot at the base price. That number matters because it's the fairest way to compare a new build against the market. According to the live MLS data for ZIP 89178, new homes (built 2023 or later) that actually closed over the last 180 days sold at an average of about $266 per square foot. So the Carol's base price pencils out below the area's realized new-construction rate — before you add design-center upgrades, which is where a builder makes its margin.
| Spec | Detail |
|---|---|
| Builder | Lennar (Everything's Included) |
| Community | Triad Springs, 89178 (Southwest Las Vegas) |
| Bedrooms / baths | 4 bed / 3 bath |
| Square footage | 2,670 sq ft, two stories |
| Starting price | $579,990 |
| Base price per sq ft | About $217 |
| Signature feature | Downstairs bedroom + full bath |
The practical read: at $579,990 the Carol lands right at the local new-construction median — 89178's active new builds carried a $569,000 median asking price in our July 2026 pull — so you're paying market for the size, and getting the flexible downstairs suite as the differentiator rather than a premium. Where you'll want an agent's eye is on the upgrade and lot-premium math, which can push the delivered price well past the base. Use our new construction hub and a filtered property search to benchmark it against everything else selling in the area.
What's Inside the Carol Floor Plan?
Walk through the Carol and the logic of the layout becomes obvious. The main floor opens from the foyer, with the guest bedroom and full bath tucked to one side for privacy, then broadens into the open-concept great room — kitchen, dining, and living in one connected space designed for how families actually gather. The kitchen anchors that space, which keeps whoever's cooking part of the conversation rather than walled off.
Upstairs, a central loft gives you a second living zone — a kids' play area, a media room, a study nook, or a teen retreat — surrounded by three bedrooms. The owner's suite is the payoff: a spa-inspired bathroom and a walk-in closet sized for two. For a growing family, that means the kids and the primary bedroom share a floor while the downstairs suite stays free for guests or grandparents. For a remote-work household, the downstairs bedroom becomes an office with a door and its own bathroom, and the upstairs loft absorbs the family's daily life. It's a genuinely versatile 2,670 square feet.
What Other Floor Plans Does Triad Springs Offer?
The Carol is one plan in a larger community. Triad Springs is organized into three collections, each a different size-and-price tier, so buyers can move up or down without leaving the neighborhood. Community pricing starts at $529,990.
| Collection | Bedrooms | Bathrooms | Square footage |
|---|---|---|---|
| Paradise Park | 3–5 | 2–4 | 1,690–2,770 |
| Grand Canyon | 3–5 | 2–4 | 1,690–2,770 |
| Durham | 3–4 | 2–4 | 1,690–2,407 |
The Carol lives in the Paradise Park collection, near the top of that size range at 2,670 square feet. The takeaway for buyers: if the Carol's price or size isn't quite right, the same community offers smaller, lower-priced plans starting under 1,700 square feet, all served by the same location, schools, and amenities. That flexibility is worth touring the whole community rather than fixating on one model — and it's why we walk buyers through every collection before they commit.
What Does the Carol Look Like on Camera?
A spec sheet can't show you ceiling height, natural light, how the downstairs suite actually feels, or the real flow of the great room — which is exactly why our team films these model homes. The tour embedded at the top of this guide walks the Carol room by room, so you can judge the layout, finish level, and scale before you spend a Saturday at the sales office or, if you're relocating, a plane ticket.
That video-first approach is deliberate. According to the U.S. Census Bureau, the Las Vegas metro keeps drawing new residents from higher-cost states, and a large share of southwest new-construction buyers are relocating sight-unseen — so seeing the home on camera first saves the two most expensive mistakes remote buyers make. If you're planning a move, our relocating to Las Vegas guide covers the logistics, and you can subscribe to the Nevada Real Estate Group channel for a new model or community tour every week.
How Does the Carol Compare to Other New Homes in 89178?
Context makes the Carol's pricing legible. Here's what the surrounding 89178 market looked like in our July 2026 MLS pull, covering both what's for sale and what recently sold.
| Metric | ZIP 89178 | The Carol |
|---|---|---|
| Active listings (all) | 191 · $499,000 median | — |
| Active new builds (2024+) | 22 · $569,000 median | $579,990 base |
| New builds sold (180 days) | 75 · $565,000 median · 43 DOM | — |
| New-build price / sq ft (sold) | About $266 | About $217 base |
| 4-bedroom active median | $532,211 | 2,670 sq ft, 4 bed |
Three things stand out. First, the Carol's $579,990 base is essentially at market — a hair above the $569,000 median for active new builds and the $565,000 median for recently sold new builds in the ZIP. Second, its base price-per-foot is meaningfully under the area's realized new-construction rate, which means the value case rests on keeping upgrade spending disciplined. Third, new homes in 89178 sold in a median of 43 days, so this is not a frantic market — you generally have time to compare, negotiate, and finance properly rather than race. According to Nevada REALTORS, builder closings have taken a growing share of valley sales as resale inventory stays tight, and the southwest is the center of that shift.
It's also worth noting how thin the new-construction pool actually is. Those 22 active new builds in 89178 span every builder and collection in the ZIP — so at any given moment, a buyer set on a brand-new home in this specific corner of the southwest is choosing from a couple dozen homes, not hundreds. That scarcity is exactly why touring a community like Triad Springs with its three collections gives you more real options than chasing one-off listings across the ZIP, and why locking in the right floor plan and homesite early matters more here than it does in the deeper resale market.
Who Is the Carol Model Best For?
The Carol fits three buyer profiles especially well, and it's worth being honest about who it doesn't fit. It's ideal for multigenerational households — the downstairs suite lets aging parents or adult children live with real independence and no stairs. It's ideal for families who host — guests get a private bedroom and bath instead of a pull-out couch. And it's ideal for remote-work households — that ground-floor room with its own bathroom becomes a professional office while the upstairs loft carries daily family life.
Who should look elsewhere? A single buyer or couple who won't use four bedrooms and doesn't need the downstairs flexibility may get more value from a smaller Triad Springs plan in the Durham collection, or from a single-story home if stairs are a dealbreaker. And a buyer set on a large private yard should study the specific lot, since new-construction lots in this price band run efficient. According to GreatSchools, the area's Clark County School District assignments are a factor for families — verify the exact zoned schools for the specific homesite, since assignments vary within a single ZIP.
What Does Lennar's "Everything's Included" Actually Include?
Lennar builds under an Everything's Included model, which is worth understanding because it changes how you shop. Rather than a low base price plus an à-la-carte design center where every upgrade is extra, Lennar bundles a defined package of features — appliances, certain finishes, smart-home components, and energy features — into the price as standard. The upside is transparency and fewer surprise line items; the price you see is closer to the price you pay, and two buyers of the same plan get largely the same home.
The trade-off is less customization. If you want to hand-select every finish, a build-to-order builder with an open design center gives you more control (and more chances to overspend). With Lennar, the negotiation shifts away from picking options and toward financing incentives and lot selection — which is where your leverage actually lives on an Everything's Included home. That's a different playbook than a design-center builder, and it's one an experienced buyer's agent runs for you.
What Are the Hidden Costs at Triad Springs?
The base price is rarely the delivered price on any new home, and Southwest Las Vegas communities carry a few specific add-ons. Budget for these before you fall for the model.
SID/LID special assessments. Many newer southwest communities carry Special Improvement District or Local Improvement District assessments that fund infrastructure — roads, utilities, landscaping — and appear as a separate line on your property-tax bill for years. Always ask for the SID/LID balance on the specific homesite before you write.
Lot premiums. A larger, corner, or better-positioned lot can add anywhere from $10,000 to $50,000 or more over the base. According to the Clark County Assessor, your assessed value — and Nevada's low, capped property tax — reflects the fully built price including premiums, though the state's 3% owner-occupied assessment cap keeps annual increases predictable.
HOA dues and mortgage math. Triad Springs carries a homeowners association; get the current dues and what they cover before you finalize your budget. And with rates elevated, run the real payment. According to Freddie Mac's Primary Mortgage Market Survey, 30-year fixed rates have held in the high-6% range through 2026, which is exactly why Lennar's financing incentives — discussed below — can be worth more than any price cut.
How Does Buying at Triad Springs Compare to Resale in the Area?
Many southwest buyers weigh a new Lennar home against an existing resale nearby. Neither is universally better; here's the head-to-head on the dimensions that decide it.
| Dimension | Triad Springs (new) | Area resale |
|---|---|---|
| Price per sq ft | About $217 base | About $243 (89178 sold) |
| Condition | Brand new, warranty | Varies, possible deferred maintenance |
| Finishes | Everything's Included package | Previous owner's choices |
| Landscaping / yard | Often bare — you build it | Established |
| Move-in timeline | Move-in ready or built-to-order | ~30–45 days |
| Incentives | Builder rate buydowns, credits | Seller credits, price cuts |
| Added costs | SID/LID, lot premium | Immediate repairs / updates |
Interestingly, the sold data shows the 89178 resale market averaged about $243 per square foot over 180 days while area new builds sold nearer $266 — yet the Carol's base pencils to about $217. That gap is the value story and the caution at once: the base is competitive, but design and lot choices are what move the delivered price. For a full framework, see our new construction vs. resale comparison, and weigh it against nearby resale on our Las Vegas homes-for-sale search or the Spring Valley homes page.
What Should You Negotiate on a Lennar Home in 2026?
On an Everything's Included home, you don't negotiate the finish package — you negotiate financing and lot. With rates elevated, Lennar and its in-house lender compete primarily on rate buydowns (temporary or permanent below-market rates), closing-cost credits, and occasionally lot-premium concessions on standing inventory the builder wants to close before quarter-end. These incentives are usually tied to using Lennar's lender, so the smart move is to compare the all-in cost — rate, points, and credit combined — against an outside lender's quote rather than assuming the builder's offer is automatically best.
The biggest incentives land on quick-move-in homes, not fresh build-to-order, because those are the ones sitting on the builder's books. An agent who tracks which southwest communities are behind on their sales targets knows where the real leverage is on any given week. That kind of timing intelligence is exactly what a buyer touring a single model alone never has access to.
Why Tour Triad Springs With Nevada Real Estate Group?
Here's the move that protects your money on any builder purchase, Triad Springs included: register your own buyer's agent on your very first visit, before you sign in at the sales office. The Lennar sales agent represents the builder, not you. Your buyer's agent costs you nothing — the builder pays the buyer-agent commission from its marketing budget — and gives you someone to compare incentives, scrutinize the contract, order an independent pre-drywall and final inspection, and hold the builder to the timeline. Tour and register alone, and some builders will later refuse to recognize an agent, leaving you to negotiate the biggest purchase of your life against professionals who do it daily.
Nevada Real Estate Group is the #1 real estate team in Nevada (and #44 in the nation), with 9,600+ closed transactions and over $4.85 billion in career sales volume, a 150+ agent team, and 9,061+ verified five-star reviews.

Frequently Asked Questions
How much does the Carol model at Triad Springs cost?
The Carol starts at $579,990. It's a 4-bedroom, 3-bathroom, 2,670-square-foot two-story home by Lennar, which works out to roughly $217 per square foot at the base price — below the approximately $266 per square foot that new homes in ZIP 89178 actually sold for over the last 180 days. Design-center upgrades and lot premiums add to the delivered price.
Where is Triad Springs located in Las Vegas?
Triad Springs is at 9686 Paradise Park Drive, Las Vegas, NV 89178, in the southwest valley off Blue Diamond Road, near Mountain's Edge and the 215 Beltway. It's roughly 20 minutes from the airport, the Strip, and Summerlin, and close to the retail and dining along the Blue Diamond and Durango corridors, plus Nathaniel Jones Park.
Who builds Triad Springs and what's the price range?
Triad Springs is built by Lennar under its Everything's Included model, with community pricing starting at $529,990. It offers three collections — Paradise Park, Grand Canyon, and Durham — ranging from about 1,690 to 2,770 square feet and 3 to 5 bedrooms, so buyers can choose different sizes and price points within the same community.
What makes the Carol floor plan special?
The Carol puts a full bedroom and bathroom on the main floor, separate from the open-concept great room, with three more bedrooms and a loft upstairs around the owner's suite. That downstairs suite is ideal for multigenerational living, long-term guests, or a private home office — a layout many two-story homes in this price class don't offer.
Is the Carol model good for multigenerational living?
Yes. The main-floor bedroom and full bath let aging parents or adult children live with real privacy and no stairs, while the family occupies the upstairs bedrooms and loft. It's one of the most-requested layouts among Las Vegas buyers for exactly this reason, which is a big part of the Carol's appeal.
Do I need my own agent to buy at Triad Springs?
Yes, and you should register your agent on your first visit, before signing in. The builder's sales agent works for Lennar, not you. Your buyer's agent costs you nothing — the builder pays their commission — and protects your leverage on incentives, contract terms, inspections, and timeline. Some builders won't recognize an agent brought in after you've registered alone.
What are SID and LID taxes at Triad Springs?
Special Improvement District (SID) and Local Improvement District (LID) assessments fund infrastructure like roads, utilities, and landscaping in many newer southwest communities, appearing as a separate line on your property-tax bill for years. They can add meaningfully to your monthly cost, so request the SID/LID balance on the specific homesite before writing an offer.
How does the Carol compare to resale homes in 89178?
The Carol's base price pencils to about $217 per square foot, while 89178 resale homes averaged around $243 and new builds around $266 per square foot over the last 180 days. New construction gives you a warranty and current finishes; resale often gives you a mature yard and faster close. The base is competitive — design and lot choices determine the final delivered price.
