Thinking about a foothills new build? Start with our relocation and neighborhood guide, then let us walk you through builders, phases, and pricing.

What Is Avimor and Where Is It?

Avimor is a master-planned community in the foothills north of Eagle along Highway 55, building out across thousands of acres. It remains one of the larger new-construction stories in the Treasure Valley, and one of the few places in the valley where new homes come with genuine foothills surroundings rather than a flat subdivision lot.

The community pairs new homes with trails, open space, and its own amenities, aimed at buyers who want current construction and room to breathe within a short drive of Eagle. Because it is still early in a long build-out, the mix of phases, builders, and home styles shifts year to year.

That constant evolution is exactly why a current update is useful. What was available when you last looked is probably sold, and the phase you can actually buy into today determines both your lot and your timeline.

What New Phases Are Opening at Avimor?

Avimor releases phases as earlier ones fill in, and each release carries its own lot sizes, floor plans, and price points. Avimor identifies Phase 11 as its next phase opening, describing lots that start at approximately a quarter acre and rise from there, with homes backing to open space, per Avimor. The community also lists sections extending into Boise County alongside its Eagle-addressed neighborhoods.

For buyers, an opening phase means two things worth weighing against each other. You get fresh inventory and the chance to choose a lot rather than settle for what is left, which in a foothills community is a bigger deal than it sounds; the difference between a lot backing to open space and one backing to a future street is permanent.

You also get an active construction environment for a while, with the noise, traffic, and changing views that go with it. That is the honest cost of buying early, and whether it registers as exciting or exhausting depends entirely on the buyer. Phase availability changes as homes sell, so confirm current releases directly with the community before you plan around any specific lot.

Which Builders Are Active at Avimor?

Tresidio Homes builds at Avimor, with homes roughly 15 minutes from downtown Eagle, per Tresidio. Builder rosters at a community this size shift by phase, so the right move is confirming who is building in the specific phase you are considering rather than relying on a general list.

Buying new construction means choosing a builder as much as choosing a house. Each brings its own floor plans, finish levels, warranty terms, and incentive programs, and those differences outlast the model home that sold you on the community. Comparing builders inside the same development is one of the most useful hours a buyer can spend, and it is easy to skip when a model home is doing its job well.

The incentive question deserves particular attention right now. Ada County new construction pending sales rose 20.7% year over year in July while new-build inventory fell 8.3%, per BRR, which means builders across the county are seeing genuine demand. That backdrop shapes how much room you have to negotiate, and it varies by builder and by how much standing inventory each is carrying.

What Does the Approved Growth Plan Mean?

The long-range plan is the part buyers most often miss. The Eagle City Council approved a sub-area plan covering 2,464 additional residential units as part of Avimor's growth, per the Idaho Press.

That plan could eventually add roughly 5,000 residents along with about 660,000 square feet of commercial development, per the same reporting. None of it arrives at once; this is a multi-year vision rather than a construction schedule, and approvals, infrastructure, and market conditions all shape the actual pace.

For a buyer, the takeaway cuts both ways honestly. Growth on that scale can bring services and amenities closer to home over time, which is a real benefit in an area that has historically had few. It also means the community around you will keep changing for years, and the open view from your lot today is only permanent if something specific protects it. Asking what is planned adjacent to a lot, before you commit to it, is the single most useful question in a community like this one.

Is Buying New Construction at Avimor Right for You?

It depends on what you want from both a home and a neighborhood, and the answer splits people cleanly.

Avimor suits buyers who value current construction, foothills surroundings, and being early in a community still taking shape, and who genuinely do not mind living near ongoing development. New construction also carries its own process: builder contracts, upgrade selections, construction timelines, and lender choices all work differently than a resale purchase, and the contract terms favor the builder unless someone is reading them on your behalf.

Every buyer's situation is different, and weighing Avimor against an established Eagle neighborhood comes down to your priorities and your timeline. That is the comparison we walk clients through so the foothills decision gets made with clear eyes rather than on the strength of a well-staged model home.

Common Scenarios We See in the Treasure Valley

Three recent client situations show how the foothills decision actually resolves.

The first were buyers who fell hard for a model home and were ready to write that afternoon. We slowed them down for one week to compare two builders in the same phase on warranty terms and standard finishes rather than on the decorated model. They chose the other builder, got a better warranty, and spent less on upgrades to reach the same finish level.

The second was a couple weighing Avimor against an established Eagle neighborhood at a similar price. They toured both in one day, which is the fastest way to feel the difference between new and settled. The mature trees won. There is no wrong answer in that comparison, only the one that matches how much change you want around you.

The third was a buyer who asked the question most people forget: what is planned for the parcel behind this lot. The answer changed which lot he chose within the same phase, at the same price. That single question is worth more than any upgrade on the selection sheet.

Three foothills decisions, and in each one the useful work happened before anybody signed anything.

Is Avimor a good place to buy new construction?

It can be, for buyers who want newer homes, foothills surroundings, and the chance to choose a lot early. The trade-offs are living near ongoing construction and navigating the new-construction contract process. Weighing it against an established Eagle neighborhood depends on your timeline and how much change you want nearby.

Ada County new construction posted a $609,900 median sales price in July, up 9.4% year over year, with new-build homes averaging 48 days on market, per Boise Regional REALTORS.
