New Construction Update: Builders Sharpen Their Pencils & the Southwest's Final Lots

The Big Picture: The Buyer's Market Arrives

Let me start with the number that changes the conversation: Home Builders Research reported August 2026 net new-home sales of 502 across Southern Nevada, down 31% from a year earlier, with builders also pulling back on permits. That follows a year-long slide, 755 net sales in February, down 22% year over year, and 694 in April, and it pushed the builders into their sharpest price and incentive response of the cycle.

The response is real and it is measurable. Builders are offering rate buydowns of $20,000 to $50,000 and average concessions of $30,000 to $60,000, and they are shrinking floor plans to hit lower price points rather than walking away from the market. Lennar's June through August net earnings fell about 50% year over year, from roughly $1.2 billion to $591 million, which tells you how much the volume players are willing to trade margin for sales. For a buyer, that is leverage, and it is exactly the kind of leverage that has not existed in this corridor for years.

Toll Brothers' Ivyleaf Square: Fresh Product in the Southwest

The freshest builder news in the corridor is Toll Brothers' Ivyleaf Square, sold through its StoryBook Homes division, with 15 home sites offering five-bedroom, two-story plans and starting prices captured around $545,000 as of late September. It is a small, focused release, which is exactly the pattern in the Southwest right now: the big master plans are closing out, and the new product is arriving in tight, high-value pockets instead of thousand-home phases.

Ivyleaf Square matters for two reasons. First, it is proof that premium builders still see the Southwest as a place to put new product, even in a slower market. Second, a five-bedroom, two-story plan in the mid-$500,000s is a genuine move-up option for families who thought they had aged out of new construction. Every active builder and community in the corridor is tracked on my new construction page.

KB Home: Landings & Reserves at Aven

KB Home remains the most active mid-market builder in the corridor, with 28 communities priced from about $317,000 to $883,000 per June data. Its big early-2026 news was the grand openings at Landings and Reserves at Aven in the Southwest, both starting from the mid-$400,000s, and those communities are still the ones I point entry-level and first-time buyers toward when they ask where the attainable new product went.

KB Home also keeps running its newer Aspire section in the Mountain's Edge area, one of the few genuinely active pockets left in that master plan. If you are comparing a KB Home plan against a resale in the same ZIP, the incentives are the story right now: rate buydowns and closing-cost credits are doing more work on a new build than they have in years.

Lennar & D.R. Horton: The Volume Players

Lennar closed 1,796 homes in 2025, the valley's No. 1 builder, and in the Southwest it operates Windsor Place, a 34-lot single-family community, plus Triad Springs with quick move-in two-story homes, all part of roughly 50 Lennar communities across the Enterprise and Southwest corridor priced from about $277,000 to $1.28 million.

D.R. Horton overtook Lennar as the valley's No. 1 builder in the third quarter of 2025, helped in part by two townhome projects in the Southwest, and it runs 17 communities in the Enterprise and Southwest area priced from about $308,000 to $822,000. When the two biggest volume builders in the valley are both leaning into this corridor, that is the market telling you where the demand has settled. Pulte rounds out the top tier with 22 communities in the Enterprise and Southwest area priced from about $307,000 to $2.40 million.

Mountain's Edge: The Last 75 to 250 Homes

Mountain's Edge, the roughly 3,500-acre master plan that grew past 12,000 single-family homes, is substantially built out and closing its final chapters. The remaining inventory runs roughly 75 to 250 new homes depending on how you count the villages, with KB Home's Aspire among the few active pockets and new-build pricing from the low $400,000s at the Cornerstone entry tier, $350,000 to $425,000, up past $1 million at Toll Brothers' larger offerings.

The honest framing for buyers is this: the master plan's parks, trails, and schools are done, which means you are buying a finished community with a closing-out price sheet, and closing-out is where the incentives live. For the full trade-off picture, my Mountain's Edge spotlight walks through the villages and what resale looks like after the last lot sells.

Southern Highlands: Westridge Enclave from $700K

Southern Highlands remains the Southwest's luxury anchor, and Lennar is pre-selling its newest release there: Westridge Enclave, from around $700,000, with NextGen single-family plans running 2,126 to 3,438 square feet, targeted for early 2027. Across the southwest core ZIPs, roughly 185 new-build listings sit on the market at a median near $570,000, with ZIP 89141, the Southern Highlands and Enterprise side, leading at about 48 listings around $559,950.

Toll Brothers remains active in the guard-gated, golf-course enclave, and the advice for luxury buyers is unchanged: the interest lists are the product now. Westridge Enclave's door price is set, the list is open, and first pick in 2027 goes to the people who got on it first. The school feeders for the community's newer west side are all on my schools page, and the full community picture is in the Southern Highlands spotlight.

Rhodes Ranch, Spanish Trail & Nevada Trails: Resale Stories

My own community, Rhodes Ranch, is now largely a resale story, with the newest nearby construction being Silver Bow, a new southwest-valley community near the Rhodes Ranch Country Club. Inside the guard gates, the remaining new product is concentrated in the last rows, and once those close, the neighborhood trades on resale. If you want the block-by-block picture, the Rhodes Ranch deep dive goes through it.

Spanish Trail and Nevada Trails are both fully built out and resale only, with no active new-home releases reported this year. Spanish Trail, the guard-gated country club dating to 1979 with its 27-hole course, still carries listings from around $505,000 up past $3.4 million, and the new-construction route there is the custom teardown-and-rebuild behind the established gates. Nevada Trails is the same story: finished, quiet, and carried by its parks and trails.

Durango's North Expansion: Halfway & the Food Hall Shuffle

The anchor of the corridor, Durango Casino & Resort's $385 million North Expansion, hit its halfway mark in September when crews installed the project's massive steel truss, roughly 180,000 pounds, and completion is targeted for late 2027. The roughly 275,000-square-foot podium expansion will add about 400 slot machines, a 36-lane bowling alley, luxury movie theaters, new restaurant and food-hall concepts, and Moonshine Flats, the two-story country-music venue from San Diego announced in partnership with Good Time Design.

The freshest development news is the food hall shuffle: in early October, Station Casinos closed three Durango food-hall outlets as part of the north-side development, making room for a larger food hall in the expansion. That is a normal part of a build like this, but it is worth knowing so nobody shows up expecting their usual counter. The whole corridor picture, including The Bend and UnCommons, is in my Durango corridor guide.

The Bend & UnCommons: Investment Keeps Compounding

The Bend, the Dapper Companies' dining and entertainment complex at Sunset and Durango, is now largely built out and operating, with 17 tenants across the property. In July, five of its retail buildings were listed for sale at $40.6 million, which is not a sign of weakness, it is a sign of institutional confidence: investors buy income-producing retail exactly when they believe the surrounding rooftops will keep growing.

UnCommons, the 40-acre, roughly $850 million mixed-use campus by Matter Real Estate Group, refinanced in March with a $310 million loan from TPG, then announced its final building in May, a fifth three-story mixed-use structure on the campus's west side. At full buildout the campus will hold about 500,000 square feet of office space, 91,000 square feet of retail, and more than 830 residential units, including Vestra at UnCommons, the rental residences whose first building opened in 2023 with studios from around $1,760 a month. All of that residential and office density is the future demand pool for the neighborhoods around it.

New Roads: Ramps, Rainbow & the Beltway

The roads keep pace with the rooftops. The new CC-215 on-ramps at Sunset Road and Durango Drive are under construction, one from Sunset onto the Beltway and one from Durango northbound, with the Durango off-ramp widening and a pavement overlay on the Beltway from Durango to Tropicana, and traffic restrictions have been active through the summer. Rainbow Boulevard's roughly five-mile pavement, signal, and ADA improvement project from Tropicana to Silverstream began overnight lane closures in late July and runs through summer 2027, while Clark County continues widening Rainbow between Wigwam and Blue Diamond.

For anyone watching the Southwest grow, this is the part that feels personal. The neighborhoods were built fast, and now the roads, the ramps, the retail, and the office space are all catching up at once. The drive-time picture, including what the new ramps mean for your commute, is on my commuting guide.
