Pleasanton's newest luxury community — 43 Toll Brothers estates from 2023 off Lund Ranch Road in five plan variants, 4,035–4,598+ sq ft, now entering resale.
Every so often, a genuinely new neighborhood arrives in Pleasanton — and Diamond Canyon is the newest of them all. Built by Toll Brothers beginning in 2023 off Lund Ranch Road in south Pleasanton, this is an exclusive community of just 43 estate-sized homes, and it sold out almost as fast as it opened. I followed this community closely from its launch and walked the Dresden model home during the sales phase, so this guide comes from firsthand familiarity — and that matters here, because Diamond Canyon is now entering its resale era.
First, the name housekeeping, because Pleasanton loves to reuse a good word: Diamond Canyon is not the Diamond Collection, the 1989 pocket beside Mission Park (that one has its own guide on this site). Diamond Canyon is the brand-new Toll Brothers community in the Lund Ranch corridor. Different decade, different builder, very different price point.
Diamond Canyon was built around three core designs offered in five variants, all two-story with three-car garages and five-and-a-half baths:
The Fortuna (4,035+ sq ft) blends sophistication and functionality, offered in a base four-bedroom configuration and a five-bedroom Fortuna European Ranch variant. The Regent (4,327+ sq ft) brings five bedrooms in both its standard form and the Regent Tuscan variant. And the Dresden (4,598+ sq ft) is the flagship — five bedrooms and the most expansive living space in the community. Having toured the Dresden model myself, I can tell you the photos undersell it: the scale of the great room and the indoor-outdoor flow are what buyers remember.
Standard features across the community were anything but standard: first-floor ceilings soaring to 20 feet, great rooms with included fireplaces, grand kitchens with extensive islands and cabinetry, impressive entryways, and expansive luxury outdoor living spaces. Exterior elevations alternate among Tuscan, Farmhouse, and European Ranch styles with stone and metal accents, giving the streetscape genuine architectural variety.
Then there's the personalization layer. Buyers customized through the Toll Brothers Northern California Design Studio, selecting from over 1,000 options and combinations — multigenerational suites, dedicated offices, cabanas, bonus rooms, primary-suite decks, floating staircases, and multi-panel stacking doors that open entire walls to the backyard. Original pricing ran from about $3.5 million into the mid-$4 millions depending on plan, lot, and options.
With only 43 homes and construction completed so recently, Diamond Canyon resales will be scarce — and each one is effectively a near-new home without the design-studio wait. The critical work is understanding what each specific home includes: because of that 1,000-option program, two homes on the same floor plan can differ by hundreds of thousands of dollars in options, finishes, and site improvements. Comparing a Diamond Canyon resale to its neighbor's price without reading the option story is how buyers misread value here. For owners, the flip side: documenting your upgrades and homesite advantages will matter more in this community than almost anywhere else in Pleasanton when it's time to sell.
The homesites themselves range from about 10,300 square feet to over 50,000 — more than an acre at the top end — with large backyards and valley views from many positions along Lund Ranch Road and Vista Oaks Court.
The Lund Ranch corridor sits in established south Pleasanton, surrounded by mature, tree-lined neighborhoods rather than raw edge-of-town development — which is why this community felt settled from day one. Downtown Pleasanton's Main Street, with its boutiques, restaurants, and arts scene, is minutes away. Commuters get quick access to I-680 and I-580, with the Pleasanton/Dublin BART station a short drive for trips to San Francisco, Oakland, and beyond. Golf, parks, and the trail systems of the surrounding ridgelands round out the recreation picture.
Homes here fall within the Pleasanton Unified School District; school assignments are parcel-specific and can change, so verify the current assignment for any specific address directly with the district.
Diamond Canyon connects to some of south Pleasanton's most established communities — Ventana Hills and the Mission Park pocket (including the Diamond Collection) to the west, Bonde Ranch in the nearby hills, and the broader Sunol Boulevard corridor — all covered in their own guides on this site. The contrast is the point: this corridor spans everything from late-'80s contemporaries to brand-new Toll Brothers estates.
Diamond Canyon is the rarest thing in Pleasanton real estate: truly new luxury construction inside an established part of town. It sold out quickly for exactly that reason, and its first resales will draw buyers who missed the original window. Whether you're hoping to catch one of those listings or you own here and want to understand what your specific plan, options, and homesite are worth, this is a neighborhood where the details drive enormous value differences. That kind of street-level detail is where I can genuinely help.
