Echo (Hidden Valley / Echo Estates)

Echo — also referred to as Hidden Valley / Echo Estates — is a gated custom-home enclave in Brentwood, Tennessee. It is the kind of small, bespoke community where homes are built one at a time to individual designs rather than rolled out from a handful of repeating floor plans. Because new-construction availability and pricing move quickly, we don't post a price here that could be stale by the time you read it — let us pull the current pricing and availability for you before you make any decisions.

The builder and the homes

The build we have confirmed in Echo is Idlewild Custom Construction. The homes here are custom single-family residences, meaning each one is its own design rather than a set spec plan repeated across the street. That custom approach is the defining feature of the community: floor plans, finish levels, lot orientation, and square footage can vary meaningfully from one home to the next.

We don't publish bedroom counts, bathroom counts, square footage, or specific included features for individual homes here, because in a custom community those details are set per home and per contract — and they change as new builds come online. If you want to know exactly what a given home includes (and what is an upgrade versus standard), that is something we confirm with the listing side in real time so you are working from current, accurate specs rather than a generalized list.

Amenities and day-to-day living

The amenity we can confirm for Echo is a gated entry. Beyond that, the community's character comes from its custom, low-density feel rather than a long list of shared facilities. If shared amenities, common areas, or maintenance services matter to you, ask us to verify exactly what exists today and what is planned, since these details are sometimes still being finalized in newer enclaves.

Location and getting around

Echo sits in Brentwood, in Williamson County's stretch of Middle Tennessee. Rather than quote a drive time we can't stand behind, we'd encourage you to clock the routes that actually matter to your life — your office, the kids' activities, the airport, your go-to grocery — at your real departure times. Morning and evening traffic patterns can differ a lot from a midday test drive, so a couple of trips at the hours you'll genuinely be commuting will tell you far more than any estimate. We're happy to map the specific routes you care about and ride along if that helps.

Who it fits

Echo is built for buyers who want a custom home in a gated Brentwood setting and value a one-of-a-kind design over a production floor plan. Because the homes are bespoke, it tends to suit buyers who want input into their home's design and finishes and who prioritize privacy and a small, gated community feel. If a custom build with a higher level of personalization is what you're after, this is the type of enclave worth a closer look — call us and we'll walk you through current pricing and what's available right now.

What to verify before you buy here

• Live pricing and current availability — these move as homes sell and new builds list, so we'll pull today's numbers for you rather than quote a figure that may be out of date.
• HOA dues and exactly what they cover (gate maintenance, common areas, any services) — and whether there are additional assessments.
• Lot specifics for the home you're considering: size, boundaries, grading, drainage, and any easements or building restrictions.
• Builder warranty terms from Idlewild Custom Construction, plus a clear line between what's included as standard versus a paid upgrade.
• Construction timeline and milestones if you're buying a to-be-built or in-progress home.
• Your real commute — drive your actual routes at the times you'll travel before you commit.

A second builder in Echo: Hidden Valley Homes

Alongside Idlewild Custom Construction, Hidden Valley Homes is active in Echo and maintains listing pages for individual lots inside the community (as of 2026-07, per hiddenvalleyhomesnashville.com). Hidden Valley Homes is a Franklin, Tennessee-based custom builder that describes over 30 years of building experience in the greater Nashville area. Seeing two builders actively working the same small enclave is useful context: it means design and finish approach can differ meaningfully depending on which builder is behind a given lot, so ask us which builder built (or is building) the specific home you're considering before you assume anything about standard finishes.

One Hidden Valley Homes listing inside Echo — publicly marketed as "Echo – Lot 3" at 1706 Reflection Ln — was designed by Jack Herr and marketed at 8,411 square feet with 6 bedrooms, 6 full baths, and 3 half baths, on a private, tree-lined lot of just over one acre with pond views, a four-car garage, and a basement recreation room (per hiddenvalleyhomesnashville.com, as of 2026-07; that specific listing is marked sold on the builder's site). We're not presenting this as "the" Echo floor plan — it's one custom build among several — but it does illustrate the scale and finish level buyers should expect to see quoted in this community.

Where Echo sits and the address pattern

Echo's homes address off Reflection Ln (also written Reflection Lane), Brentwood, TN 37027, inside the gated portion of the Hidden Valley area. Public listing aggregators (Compass, Redfin, LandWatch, Homes.com) show multiple addresses on this street — 1705, 1706, 1709, 1712, 1713, and 1715 Reflection Ln among them — consistent with a small, single-street enclave rather than a sprawling subdivision with multiple phases. We'd rather tell you that plainly than make up a lot count or acreage total we can't stand behind — ask us to confirm the exact number of remaining buildable lots and the plat details for the specific address you're evaluating.

Zoned schools (verify for your specific address)

Public listing data for addresses inside Echo shows Jordan Elementary School, Sunset Middle School, and Ravenwood High School as the assigned schools for at least one Reflection Ln property (per Redfin/Compass listing data, as of 2026-07). We don't characterize school quality, rankings, or fit here — schools are assigned by specific address and zone lines can shift, so pull the current GreatSchools.org profile and the Tennessee Department of Education report card for the exact address you're considering, and confirm zoning directly with Williamson County Schools before you rely on it.

Utilities and site infrastructure

Listing data for the Reflection Ln properties in Echo describes underground electric, water, gas, and sewer service to the community (per public listing aggregator data, as of 2026-07). That's worth confirming address-by-address if underground utilities matter to you, along with which specific utility providers serve the lot (water/sewer authority, electric co-op or utility, and gas provider), since Brentwood has more than one provider operating across different parts of the city.

Recent sales and current pricing context (dated — not a forecast)

Per a Brentwood gated-communities market roundup (nashvillehome.guru, as of 2026), two Echo homes sold in the trailing 12 months at $2,167,395 and $4,936,606, both identified as 2025 new construction, with active listings continuing above $5 million as of that writing. A separate builder-guide summary for Brentwood new construction lists Echo's low end at roughly $2.2M and cites an active new-construction listing on Reflection Ln (1706 Reflection Ln) at $5,450,000 for 8,816 square feet with 6 bedrooms and 9 total bathrooms (nashvillehome.guru, as of 2026-06). These are historical transaction and listing figures only — we can't predict where prices in Echo will go from here, and by the time you're reading this some of these homes may already be under contract or sold. Ask us to pull live MLS data for whatever's currently active before you anchor on any number above.

Amenities beyond the gate

Beyond the gated entry already noted, aggregator descriptions of Echo reference mature trees throughout the enclave and a community pond as part of the setting (per public real-estate aggregator summaries, as of 2026-07) — several of the individually marketed lots specifically advertise pond views. We haven't been able to independently confirm HOA-maintained amenity details (whether the pond is a shared/maintained feature versus a natural feature on private land, for example), so this is exactly the kind of thing worth verifying in the HOA documents before you buy rather than assuming from marketing copy.

Frequently asked questions

Is Echo the same as "Echo Estates" in Franklin? No — there is a separate, similarly named community called Echo Estates (and a related Preserve at Echo Estates) in Franklin, TN 37069. This page is about Echo / Hidden Valley / Echo Estates in Brentwood, on Reflection Ln. Don't let the similar names cause you to compare the wrong pricing or specs — ask us which one you actually mean and we'll pull the right data.

How many lots are in Echo? Public real-estate aggregator descriptions put the enclave at around 13 lots on a single street (Reflection Ln), which fits the small, private character of the community, but we'd rather confirm the current, exact number with the builder or a current plat before quoting it as fact — ask us and we'll verify.

Can I buy land in Echo and choose my own builder? Based on what's publicly marketed, both Idlewild Custom Construction and Hidden Valley Homes are actively building here, and the custom nature of the community suggests some flexibility — but lot ownership, builder tie-ins, and any restrictions are the kind of thing that varies by developer agreement and needs to be confirmed lot-by-lot. Call us and we'll find out what's actually available for the lot you're interested in.

What does a home in Echo typically include? Because these are fully custom builds, standard inclusions vary by builder and by contract rather than following one repeated spec sheet. Publicly marketed examples we've seen include four-car garages, finished basements with recreation rooms, and high-end finish packages — but treat those as illustrations of the caliber of home being built here, not a guarantee of what any specific lot includes.
