Milton Pool Cost on a 1-Acre Equestrian Lot — The $225K Build, Line by Line

On a 1-acre AG-1 equestrian lot in Milton with a 9-foot grade drop across the pool envelope, the final delivered number was $225,000 — and every dollar landed exactly where we said it would eight months earlier.

Here is a statistic most Milton homeowners do not know: the 2024 Fulton County Realtor data puts resale recovery on equestrian-zoned Milton parcels between 62% and 78% at five-year resale when the backyard includes a properly engineered pool, integrated pavilion, and travertine deck system. That spread is not random. The low end of the range is the homeowner who bought on price alone and ended up with a vinyl-liner rectangle on a sloped lot with no pavilion, no outdoor kitchen, and a liner crease visible every time the water dropped below the skimmer. The high end is the homeowner who treated the backyard as a single integrated build — the way a Manor or Cogburn Estates buyer evaluates it when they walk the property three summers later.

This post is the line-by-line breakdown of one such integrated build: a 20×40 gunite pool with a raised spa, a 14×18 cedar pavilion, and 1,200 square feet of travertine decking, all delivered on a rolling 1-acre lot between Freemanville Rd and Hopewell Rd for exactly $225,000. No mystery line items. No “contingency absorbed the overage” language at closeout. The budget below is the budget we signed, and the budget we delivered.

If you are pricing a pool in Milton right now — Crooked Creek, Atlanta National, The Manor, White Columns, Cogburn Estates, Hopewell Plantation — this is the number behind the number. Every section below is one line on the final invoice, and every line has a reason it costs what it costs.

1. Shell, Plumbing & Steel — $78,000

The structural shell is the single largest line on any custom pool build, and in Milton it carries a premium that Alpharetta or Johns Creek shells do not. The reason is grade. Milton’s rolling topography — a product of the Etowah River tributary system cutting through weathered Cecil clay over granite — means most estate lots have 6-to-14-foot grade changes across the backyard. This particular lot dropped nine feet between the rear door of the house and the proposed pool coping elevation. That translates directly into one line: retaining structure inside the shell package.

The $78K covers: excavation of roughly 420 cubic yards (slightly elevated because we hit a saprolite shelf at 7 feet on the downslope side and had to extend the dig by 18 inches to found the shell below the weathered zone); 1,200 linear feet of #3 and #4 rebar tied on 6-inch centers in the floor and 8-inch centers up the walls; a 10-inch gunite shell thickened to 14 inches on the downslope wall where it doubles as the earth-retention element; full return and suction plumbing in Schedule 40 PVC with 2.5-inch mains pulled back to the equipment pad; and dual main drains with an anti-entrapment cover stack rated to VGB 2008.

One note on the saprolite. Milton pool excavations occasionally hit a shelf of partially weathered granite at depths between 5 and 9 feet. It is not true rock — a track hoe with the right bucket and teeth will still cut it — but it slows the dig by 30-50% and occasionally forces a jackhammer attachment. We priced that possibility into the $78K as a soft contingency. On this specific lot, we used the jackhammer for about four hours. On a different lot 800 yards east, we hit clean clay all the way down. The price did not change either way; that is what a fixed-price excavation clause is for.

2. Pebble Tec Sheen Interior Finish — $16,000

Interior finish is where the majority of homeowners get quietly upsold into the wrong product, and it is also where most resale value leaks out. On this build the owner specified Pebble Tec Sheen in a blue-grey aggregate blend — the polished variant of standard Pebble Tec, with a smoother hand-feel underfoot and a slightly more reflective water surface. The square footage came in at 1,080 surface-square-feet of interior across the pool and spa.

At a delivered rate of roughly $14.80 per interior square foot installed, the math lands at $15,984. We rounded to $16K for the proposal. The included scope: acid wash and prep of the cured gunite; bond coat; hand-applied Pebble Tec Sheen; acid exposure of the aggregate; 30-day start-up chemistry walk-through with the owner on a printed water-care log.

Why Pebble Tec Sheen and not a plaster finish that would have shaved $6,000 off this line? Two reasons. First, plaster in a Milton well-water environment (many estate lots on Freemanville and Hopewell pull from private wells with higher-than-municipal calcium hardness) will show mottling inside 24 months. Second, at five-year resale the interior finish is the first thing a buyer’s inspector photographs. A Pebble Tec Sheen surface at year five looks like a plaster surface at year two. That gap is what the $6K is buying.

3. 1,200 sqft French-Pattern Travertine Deck — $38,000

Deck square footage on this build is 1,200 — generous for the pool footprint, and deliberately so. Milton homeowners entertain outdoors in a way that Alpharetta subdivision homeowners often do not. Ten-person dinners, polo-season brunches, Atlanta Polo Club fundraiser afterparties. The deck has to carry furniture, a dining table for eight, and circulation around the pavilion and spa without feeling like a narrow band of stone.

The spec: Turkish Ivory travertine, honed and filled, 16×16 / 16×24 / 24×24 / 24×36 French-pattern layout, 1¼-inch thickness, set on a concrete sub-slab with polymeric sand joints. The coping matched — bullnose travertine, 12×24, mitered at the skimmer throat and radius-cut around the raised-spa fascia.

Delivered cost: $38,000, or roughly $31.66 per square foot installed. That number is honest. It includes: sub-slab pour, travertine material delivered from our Suwanee distributor, cutting and setting labor, polymeric sand, joint brushing, a sealer coat, and tear-out haul-off. It does not include a travertine-grade sub-drain system, which we recommend and priced separately at $2,200 — and which this owner opted into but we rolled into the landscape line below.

Why travertine and not concrete or pavers? On a Milton equestrian lot, the deck is read by the buyer as part of the estate-property character. Concrete reads as subdivision. Pavers read as neutral. Travertine reads as estate-grade. At resale, inside the $1.2M-to-$6M Milton range, that read is worth more than the $12,000 premium over a mid-grade paver deck.

4. 8-Linear-Foot Raised Spa with Three Scuppers — $28,000

The spa on this build is not an afterthought. It is an 8-linear-foot raised structure — 8 feet wide, 7 feet deep, bench seating for six adults, elevation 18 inches above pool coping — with three bronze sheer-descent scuppers spilling back into the pool. The scupper wall is a 32-inch-tall raised feature clad in the same travertine as the deck, with a mitered cap.

Pricing breakdown of the $28K: spa shell gunite and steel ($6,800), dedicated 400,000 BTU Pentair MasterTemp heater ($3,900 for the unit plus $1,400 gas line and tie-in), spa-only plumbing loop with 2-inch suction and returns ($2,400), six therapy jets and one flow-control valve ($1,800), scupper housings and bronze spout hardware ($3,200), scupper wall travertine cladding with mitered cap ($4,100), automation integration so the spa can be run from the owner’s phone via Pentair IntelliCenter ($2,400), and spa-specific electrical and bonding ($2,000).

The three-scupper specification is not decorative. On a sloped Milton lot where the pool sits 9 feet below the house, the visual from the rear deck of the house is the scupper wall — not the pool surface. Three scuppers means three points of moving water in the sightline, at eye level, at night, uplit from behind. It is the single biggest perceived-value line in this entire build. At five-year resale, the listing photo the agent will lead with is the scupper wall at dusk.

5. Integrated 14×18 Pavilion with Cedar Ceiling — $42,000

Milton’s rural-preservation character means buyers expect structure — real structure — in the backyard. Not a pergola, not a shade sail. A pavilion with a solid roof, a finished ceiling, and a power plan that supports a kitchen. The 14×18 pavilion on this build was designed in coordination with the pool deck so the roofline reads as part of the pool envelope, not an afterthought bolted on.

The $42K breakdown: engineered footings and concrete piers (the pavilion sits on clay subgrade and required six piers to frost depth, tied into the deck sub-slab) at $4,800; pressure-treated structural frame with 8×8 posts and LVL ridge at $6,200; standing-seam metal roof with ice-and-water shield at $9,400; tongue-and-groove Western Red Cedar ceiling, 1×6 boards, clear-coated, at $7,800; three 52-inch outdoor-rated ceiling fans on switches at $2,400; recessed deck-level LED lighting at $2,100; electrical sub-panel with dedicated circuits for kitchen, fans, and lighting at $3,900; permit plus engineering drawings at $2,200; post-wrap carpentry and stain at $3,200.

The cedar ceiling is the detail that pulls the whole build together visually. It takes the roofline from “covered outdoor area” to “extension of the house.” In the Manor Golf Club’s architectural review process, a cedar ceiling on a pool pavilion passes on first submission. A bare-framed ceiling or a painted-plywood soffit typically triggers a revision request and a 10-day delay.

6. The Remaining Six Lines — $61,000

The last $61K of the $225K budget splits across four items, plus contingency. None of them are glamorous, and all of them are the lines where an under-priced competitor’s budget starts to leak at week sixteen.

Landscape, Irrigation & Sod Restoration — $14,000

A 1-acre equestrian lot has a lawn — and the construction process tears up a 60-foot-wide corridor of it. The $14K restores what the excavator and the concrete truck killed: 8,400 square feet of Zoysia sod, a six-zone irrigation addition tied into the existing controller, 14 mature shrubs around the pool envelope (inkberry holly, dwarf nandina, a pair of ‘Little Gem’ magnolias flanking the pavilion), and a pine-straw bed refresh. The irrigation work was coordinated so the pool pad does not catch spray from an existing head that would drift chlorinated overspray into the beds.

Electrical & Georgia Power Service Drop — $8,000

This house was on Georgia Power (not Sawnee EMC — Sawnee serves the northern Forsyth-border parcels off Freemanville). The existing main panel was 200-amp and had two slots left. The pool equipment, pavilion sub-panel, spa heater, and scupper pumps together pulled more load than those two slots could carry. The $8K covers: a 100-amp sub-panel dedicated to the pool yard, all wire pulls from main panel to sub, bonding and grounding per NEC Article 680, equipotential bonding of the pool shell, and coordination with Georgia Power on a meter-base swap that was scheduled and completed in a single morning.

Permit, Engineering & Soft Costs — $11,000

City of Milton pool permit, pavilion permit, structural engineering stamp on the downslope wall and the pavilion, survey pin verification, creek-buffer setback confirmation (this parcel sits 140 feet from a named tributary of Cooper Sandy Creek, well outside the 25-75 ft creek-buffer setback), soil bearing report, and final as-built survey. On a Manor lot you would add $3,500-$5,000 to this line for ARC review and submittal fees.

Contingency — $10,000

We price a 4.5% contingency into every Milton build. On this project we spent $3,200 of it (the saprolite jackhammer hours plus one change order for an upgraded spa heater). The remaining $6,800 returned to the owner at closeout as a credit. That is the difference between a budget and a bid. A bid is a number someone hopes hits. A budget is a number with a contingency line and a refund clause attached.

Why $225K Is the Right Number on a Milton Equestrian Lot

The question we get every week from buyers in Cogburn Estates, King Estates, Bethany Creek, and Hopewell Plantation is some version of: “Could I do this for $160K?” The honest answer is: you could do a pool for $160K. You could not do this build for $160K. Strip the pavilion and you lose $42K. Strip the raised spa and you lose $28K. Strip the travertine and substitute concrete and you save $18K. Now you are at $137K — and you have a standalone pool on a sloped lot with a concrete deck and no covered outdoor room. That is a subdivision pool transplanted onto an estate lot, and the five-year resale data punishes it.

The $225K number is the right number when three conditions are true: the lot is 1+ acres in AG-1 zoning; the buyer profile at resale is the $1.2M-to-$6M Milton buyer who expects estate-grade outdoor living; and the owner plans to stay at least five years. Outside those conditions, a smaller number is the right number. Inside them, $225K is the floor for a build that will read as a design-integrated estate feature instead of a retrofit.

One more piece of resale math. The 62-78% recovery range in the 2024 Fulton County Realtor data is calculated against the full delivered cost. On this build, a 70% midpoint recovery means the backyard added approximately $157,500 in appraised value to the home. The net out-of-pocket at resale, in other words, is roughly $67,500 — for eight months of backyard use per year for five or more years, on an AG-1 lot that would otherwise have a 1-acre lawn and a view of the tree line. That is the real cost of ownership, and it is the number Milton homeowners should be comparing against.

What This Build Tells You About Your Own Milton Project

Three takeaways worth carrying into your own estimate conversation.

First, price the whole envelope, not the pool. The pool by itself was $122K out of the $225K total. The other $103K was deck, pavilion, landscape, electrical, permit, and contingency. If a builder quotes you a pool-only number and lets you “add the pavilion later,” you will not add the pavilion later. You will live with a pool and a grass patch. Price it together or you will live with the gap.

Second, the grade is the budget. A flat lot in Alpharetta costs $15K-$25K less on the shell line than a sloped Milton lot does. That is not a markup — it is an engineering reality. If your lot drops more than 6 feet across the pool envelope, build the retaining-wall cost into the shell number from day one. A builder who does not raise it in the first site walk is a builder who will raise it as a change order in month three.

Third, Milton is not Alpharetta. The permit office is different, the soil profile is different, the creek-buffer map is different, the HOA review cycles (especially at Atlanta National, White Columns, and The Manor) are different, and the buyer expectation at resale is different. Every number in this post is Milton-specific. Pull it across the Alpharetta line and some lines move up, some lines move down, and the resale recovery ratio moves down. If your builder quotes you the same number for a Milton lot and an Alpharetta lot, ask them to show you the last three Milton permits they pulled.
