Eagle, Idaho · Gated · On the Boise River
Riverstone is Eagle's gated, resort-style community on the Boise River — a private beach club, lakes and greenbelt paths, roughly 267 homesites including more than 100 on the water, and a curated team of luxury builders still actively building. New homes here run from around $1M well into the $2M–$3M range, with waterfront custom lots for buyers who want to design from dirt. This page covers the community, the builders, and the representation that keeps a seven-figure builder contract honest.
Sent to your inbox in about a minute · Includes available lots, quick move-ins, and this month's builder incentivesTip: In a community this size, availability moves listing by listing — a waterfront lot or a builder's quick move-in can appear and go under contract inside a month. The list I send you is current; anything printed on a website (including this one) is a snapshot. Community details below verified July 2026.
The Lay of the Land
Riverstone sits on the west side of Eagle at Palmer Lane and Moon Valley Road, just off Highway 44 with Highway 16 a minute west — which puts downtown Eagle, Eagle Island State Park, and the Banbury and River Birch golf courses all within a short drive, and the rest of the Treasure Valley within easy reach. Developed by M3 Companies on land originally platted as Moon Valley Estates, the community spans about 145 acres with roughly 267 single-family homesites — including 103 waterfront lots along the Boise River and the community's lakes and ponds. It is a genuinely gated community, which remains rare in the valley, and the density is low: lots run from cottage-scale up to more than three-quarters of an acre.
The centerpiece is the water. Riverstone's private Beach Club fronts a swimmable lake with a sandy shore — residents paddleboard, fish, and float steps from their front doors — and the clubhouse adds a resort-style pool, fitness center, and event space, all connected by greenbelt and bike paths. New construction is still active: the builder team releases homes in phases, waterfront custom lots remain available, and in 2025 the median new-build sale here was around $1.4M. I represent builders in Eagle, Meridian, and Star — including one on Riverstone's own builder team — so I see how these deals are structured from the inside. When I represent you as a buyer, that knowledge works in your direction, and the builder pays your representation. It costs you nothing.
Why Riverstone
What's Behind the Gate
Riverstone isn't one product — it's a gated community with several ways in: builder homes released in phases, quick move-ins, and waterfront custom lots. Here's how it breaks down — details verified July 2026.
The community's signature amenity: a private beachfront park on Riverstone's lakes with a sandy shore for swimming, paddleboarding, boating, and fishing — plus Boise River access. The adjoining clubhouse carries a resort-style pool with cabana areas, a fitness center, and community event spaces, tied together by greenbelt and bike paths.
Of Riverstone's roughly 267 homesites, 103 sit on the water. The developer still offers waterfront lots for custom construction — including a bring-your-own-builder path — so buyers can design from the ground up on the river or a pond. Lot sizes across the community run from about 5,400 to nearly 35,000 sq ft.
The builder team releases semi-custom and spec homes in phases — Phase II alone added 74 lots on about 24 acres. Recent homes run roughly 1,600 to 4,400 sq ft, 2–5 bedrooms, with active new-construction listings from Tresidio, Berkeley, and Highland. As of July 2026 the community carried about 20 active listings at a median near $1.05M.
Riverstone's premium tier is where the 2025 numbers landed — the median new-build sale reached about $1.4M, and Highland Homes positions its current Riverstone plans (2,840–3,710 sq ft) in the $2M–$3M range. This is Eagle waterfront luxury without leaving a gated, amenitized community.
Eagle Island State Park, downtown Eagle's dining and shops, and the Banbury and River Birch golf courses are all a short drive. The Rivervine and Moon Lake Ranch subdivisions sit just east along the river corridor, and the Legacy community is about a mile north — useful comparables if you're weighing options in west Eagle.

Waterfront lots, quick move-in homes, and incentives — including releases that never hit the public sitesThe Builders I Represent
I represent these builders in Eagle, Meridian, and Star — including Highland Homes, a member of Riverstone's own builder team. That means I know their communities, incentives, and lot releases before they hit any public site. When you buy with me as your agent, that inside knowledge works for you, at no cost to you.
Eagle-based premier custom builder with roughly two decades of high-end Treasure Valley work — and an active member of Riverstone's builder team, with current plans from about 2,840 to 3,710 sq ft positioned in the $2M–$3M range. If Riverstone is your target, this is the builder relationship that matters most.
Design-driven custom builder headquartered in Meridian, building across the Treasure Valley from Boise to Eagle to Caldwell. Founded by Idaho native Jayce Maybon, known for airtight building systems and a hands-on client experience — a strong conversation to have if you're weighing Riverstone's custom-lot path.
Building fine Treasure Valley homes since 1995 from its Meridian base, across Boise, Meridian, Eagle, Nampa, Caldwell, Star, and Middleton. A small company by design: clients talk to the builders, not a call center — useful perspective when comparing Riverstone against other Eagle-area options.
Quality-and-luxury focused builder with active Eagle-area communities including Centerra and Valnova, plus Star River Ranch and The Acres in Star. If you love west Eagle but want to compare beyond the gate, Oakmont's communities are the natural cross-shop.
Boise-based builder with one of the deeper local track records — hundreds of permitted builds across the valley. A grounded option if Riverstone pricing stretches the budget and you want a proven local builder nearby. Ask me which communities they're active in right now.
Pre-release lot knowledge. Real incentive math (what a buydown actually costs the builder tells you how far it bends). Contract and deadline protection. Design-center guidance on which upgrades return value and which just cost money.
Quick Comparison
Riverstone's developer curates a team of local builders rather than opening the community to national production names. Here's who builds behind the gate — and I can represent you with any of them.
| Builder | Style at Riverstone | Known For | Good Fit If You Want |
|---|---|---|---|
| Highland Homes ★ | Signature luxury · plans 2,840–3,710 sq ft | ~20 years of high-end Treasure Valley work; architect and designer collaboration | Top-tier finish level with a builder I represent directly |
| Berkeley Building Co. | Sophisticated semi-custom | "More thought per square foot" design-forward homes; releases here have sold quickly | Timeless architecture — and patience for the next release |
| Tresidio Homes | Custom / semi-custom | Quality-and-value custom builds; active Riverstone new-construction listings | A lifestyle-driven custom process with current availability |
| Core Building Co. | Custom, 1,300–7,000 sq ft range | Building since 2000 with sustainable-construction focus | Energy-forward custom building at flexible scale |
| Biltmore Co. | Quality single-family | Craftsmanship-and-community positioning across valley subdivisions | A relationship-driven local build |
| Northern Construction | Quality at accessible luxury pricing | In-house design resources for lighting and furnishings | Riverstone's amenities nearer the community's entry price point |
| Shadow Mountain Homes | Spacious single-family | Detail-focused builds since 1994 | Established local experience on a larger floor plan |
| Your Own Builder | Full custom on waterfront lots | The developer offers a bring-your-own-builder path on available waterfront lots | Total design control — ask me about pairing a lot with a builder I represent |

Fair Questions
Plan on roughly $1M as the practical starting point for new construction, with the 2025 median new-build sale around $1.4M and Highland Homes' current signature plans positioned in the $2M–$3M range. Resale and earlier-phase homes have traded lower — historical sales in the community span from the $500Ks up past $1.6M — but today's new-build and waterfront product lives firmly in the luxury tier. As of July 2026, active listings carried a median near $1.05M at about $446 per square foot. Pricing moves with each release, so ask me for current numbers before you anchor on anything printed.
Yes — Riverstone is a true gated community, which is still uncommon in the Treasure Valley. Behind the gate: the private Beach Club with a sandy-shore waterfront park (swimming, paddleboarding, boating, fishing), a clubhouse with resort-style pool and fitness center, community event spaces, lakes, and greenbelt bike paths, plus Boise River access. HOA dues have been quoted around $525 per quarter with a setup/transfer fee at purchase — confirm the current figures during due diligence, as associations adjust dues over time.
Both paths exist. The community was built by a curated team of local builders — Highland Homes, Berkeley, Tresidio, Core, Biltmore, Northern Construction, and Shadow Mountain — releasing homes in phases. But the developer also offers waterfront custom lots with a bring-your-own-builder option, out of 103 waterfront homesites along the river and community ponds. That's where representation pays twice: I can help you secure the right lot, then pair it with a builder whose contract and pricing I know from the inside.
The on-site sales team represents the builder and developer — competently and professionally, but not for you. Your agent compares releases across Riverstone's builders, explains contract deadlines and deposit risk on semi-custom builds, guides lot selection (waterfront premiums here are significant), and negotiates on your behalf. The builder pays the buyer-agent commission, but most builders require you to register your agent on your first visit. Show up alone first, and you may lose the right to representation in this community entirely.
Riverstone sits in west Eagle at N Palmer Lane and W Moon Valley Road, off Highway 44 with Highway 16 just west — minutes from downtown Eagle, Eagle Island State Park, and the Banbury and River Birch golf courses. The community is in the West Ada School District and feeds the Eagle High School area; published sources differ on the exact elementary and middle assignments (Star vs. Eagle schools), and boundaries do shift, so verify the current assignment for a specific address directly with West Ada before you write an offer. I do that check for every buyer I represent.
Get Oriented
The One Rule That Protects You
Here's the tricky part: the on-site sales team is friendly and helpful — and they represent the builder. If you tour or register without your own agent, many builders will not allow you buyer representation afterward, which means you negotiate the biggest purchase of your life against professionals, alone. In a community like Riverstone, where a lot premium alone can move six figures, that's an expensive way to save nothing.
Builder Rep vs. Your Representation
| Decision Point | Builder Sales Rep | Your Real Estate Agent |
|---|---|---|
| Contract terms | Uses the builder's contract, written to protect the builder | Explains clauses, deadlines, deposits, and risk points before you sign |
| Incentives & pricing | Promotes the preferred-lender package | Compares incentives across builders and runs the true loan cost |
| Lot selection | Shows what's released | Evaluates sun, traffic, noise, future phases, and resale factors |
| Upgrades | Sells the design-center packages | Prioritizes upgrades that return value over "pretty but pricey" |
| Inspections | May discourage extra inspections | Schedules phased inspections and holds the punch list accountable |
