Quick answers about this design

Worked out from this design's own model, so they differ from page to page.

How much water does this pool hold?
About 29,000 gallons. It is 40 by 20 ft with about 800 sq ft of water, 3.5 ft deep at the steps and 6 ft at the deep end. The gallons come from adding up the depth over the real floor, steps and shelf included.
How big a yard does it need?
Plan on a clear area of about 58 by 47 ft for the pool, the tub, 4 ft of deck around the water and 5 ft to the fence line. The deck as drawn here is about 60 by 49 ft.
What does this design cost?
A planning range for CT is $140,000 to $390,000 all in: the pool, deck, coping, fence and features listed on this page. Permits and engineering are not in it. It is a range built from published prices, not a quote, and real jobs usually land inside it rather than on its edges.
How long does it take to build?
Plan on about 3 to 6 months from a signed contract to the first swim. Permits take from a few days to several months, depending on the town, before work starts.

Design notes

Written with AI tools from this design's own measurements and sources, not by a pool builder. How we write

Why it works here

Rolling grounds suit a long rectangle: 40 x 20 feet and about 29,000 gallons sit comfortably beside a Georgian stone manor. The raised round tub on the far side spills over, and scuppers on the stone wall carry that sound along. Travertine pavers and flagstone coping stay pale in the sun, and the black fence fits the slate and iron.

What to watch

Raised tubs that spill over add plumbing and equipment above the main pool, and an all-tile finish is slow to repair if a tile lets go. Cold winters call for a careful, complete close.

How it reads

All tile in blue gives the water a deep, even color from wall to wall, and flagstone coping and travertine pavers keep a pale, quiet frame. The raised tub and the stone wall add a second level of texture. In midday light the pool reads rich and formal beside the Georgian manor. At golden hour the stone glows and the scuppers add soft sound. Underfoot, travertine feels smooth and cool, and the flagstone gives a firmer grip at the edge.

Through the year

Greenwich estate pools run from late spring until the oaks start to turn. Fall means leaves in the water and a long, careful close for the raised tub and the scuppers. Drain the spillway and the scupper lines fully before freezing weather, because water left in them splits tile and pipe.

Every choice, row by row (14)
ShapeRectangle

A rectangle with square corners. It is the simplest to build, covers neatly and fits a modern or formal house.

Size40 × 20 ft

A pool about 20 ft wide and 40 ft long. A big pool for swimming and entertaining, which needs a generous lot and a strong filtration plan. That is about 800 sq ft of water and about 29,000 gallons.

StepsCurved steps

Curved, wedding-cake steps. A formal, graceful way into a Roman or larger pool. The steps lead into water 3.5 ft deep.

Hot tubRaised, spills over, 7 ft round

A hot tub raised on a wall and spilling over into the pool. The raised wall gives a seat-height edge and a small waterfall, at the price of extra masonry. The tub holds about 850 gallons.

Pool finishAll tile

A fully tiled interior in small mosaic tile. The most durable and the most striking, and it asks the most from the budget. A freeze season stresses plaster, so ask how the pool is winterized to protect the finish.

Finish colorBlue finish, classic deep blue water

A blue interior. Gives a classic, deeper blue water.

CopingFlagstone

Natural flagstone with irregular edges. Gives a natural, informal look that blends with planting and rock. It runs about 120 linear ft around this pool. Coping takes the worst of freeze and thaw, so it should be rated for it and set in a flexible joint.

DeckTravertine pavers

Ivory travertine pavers. Light and cool underfoot, and a natural fit with Mediterranean and French styles. The deck is about 1,960 sq ft here. Where it freezes, the base and the joints matter more than the surface.

PlantingLawn and hedges

A green lawn with clipped hedges. Gives kids a soft place to play and a formal frame to the deck.

Pool fenceBlack aluminum

A black aluminum picket fence. A standard, durable barrier that disappears in the planting and meets most barrier codes.

Water featuresScuppers
  • Scuppers: Spouts on a wall that pour water into the pool. A classic, tactile feature that suits stone and masonry walls.
  • Features and their lines are drained or turned off for the winter.
Add to the yardPergola, Cabana
  • Pergola: A pergola over part of the deck. Gives shade and a room feeling. It may need a permit and engineering where it is windy or snowy.
  • Cabana: A small, open-sided cabana beside the pool. A shady place to change, nap or stash towels. It needs a footing and often a permit.
FurnitureLoungers, Umbrella, Dining table
  • Loungers: A pair of chaise loungers. The first thing people want on a pool deck.
  • Umbrella: A market umbrella. Cheap shade that you can move with the sun.
  • Dining table: An outdoor dining table and chairs. Turns the pool into the place where meals happen.
LightGolden hour

Shown in golden-hour light. Low sun is when the finish, the tile and the planting look their best.

Why it fits the large estate

The yard: rolling grounds with mature oaks, a stone wall, a manicured lawn, boxwood and a gravel drive. An estate lot can hold a large pool, so the design is about scale, views and a place to gather. Space lets the pool, the pergola, the outdoor kitchen and the lawn each have room. The risk is a pool that looks lost, so scale the deck and the planting with the house.

Why it fits the Colonial house

The house is a large Georgian stone and brick manor with a slate roof, symmetrical chimneys and white-trimmed windows. A colonial house wants symmetry, brick or flagstone and a formal edge. A tidy rectangle, stone coping and a calm palette respect the house's proportions. Clipped hedges and simple furniture keep the formality.

Will it work for you

Your yard, your climate, and what the pool asks of you after the build.

Will this fit your yard?

A planning estimate, built from the model's own dimensions. Your town's setbacks decide the real answer.

Clear area to plan on

58 × 47 ft

About 2,726 sq ft. The pool and tub alone is 40 × 28.5 ft.

Plan on a clear area of about 58 by 47 ft for the pool, the tub, 4 ft of deck around the water and 5 ft to the fence line. The deck as drawn here is about 60 by 49 ft.

The 4 ft walkway and 5 ft setback are our planning allowances, not code. Towns set their own distances from the water to the lot line and the house, so ask yours before you commit to a layout.

Will it fit your yard?

Enter the clear area, from the house to the back fence and side to side.

Northeast and New England: what the climate asks of this pool

A Northeast pool is built for a short season and a long winter, in yards that are often small and tight.

  • Winterizing is a yearly job. A safety cover, drained and blown lines and frost protected equipment are part of the plan.
  • Freeze and thaw is hard on stone and concrete. Pick paving that is rated for it and ask how the base is drained.
  • Space is tight and access can be hard. A crane, a narrow side yard or a rooftop changes what can be built and how it is brought in.
  • Historic districts and homeowner associations can review fences and structures. Check before you commit to a look.

Keeping it up

What this pool asks of its owner, by finish, climate, deck and feature.

  • All tile in this climate

    Tile and grout can crack in a freeze if the pool is not closed properly. Ask the builder how the tile is set and warrantied for freezing weather.

  • When it is resurfaced

    An all-tile interior is not replastered. The upkeep is in the grout and the waterline, which should be checked every year.

  • Travertine pavers deck

    Seal the travertine as the maker says and rinse it after salt or chlorine splashes. Use a stone-safe cleaner, never an acid wash.

  • Scuppers

    Copper scuppers develop a patina. It is harmless, and a clear sealer slows it if you want the shine kept.

  • The hot tub

    A hot tub is a second body of water with its own chemistry. Keep it covered between uses and drain and clean it on the maker's schedule.

  • Black aluminum fence

    A black aluminum fence needs a wash and a check of its gate latch. Near salt air, rinse it and touch up any chipped finish.

  • Winter

    Close the pool before the first hard freeze: lower the water, blow out the lines, drain or turn off the features and fit a cover. A heater or heat pump is an option for the shoulder seasons.

  • Yearly running cost

    Owners commonly budget $3,000 to $5,000 a year for chemicals, power, service and repairs (HomeAdvisor, in-ground pool cost, 2026).

Cost and timeline

A sourced range to plan with, and how long it takes.

What this design costs: a planning range

Built line by line from this design's own measurements and published prices. It is a range to plan with, not a quote.

Planning range, CT

$140,000 to $390,000

Everything on this page, built: the pool, the deck, the coping, the fence and the features. It is a range, not a quote. Every line is at its lowest published price for the low end and its highest for the high end, so a real job lands inside it rather than on an edge.

Prices are scaled for CT by a damped regional factor of 1.02 (the state's cost of living is 103.6 against 100 for the US, and we use half the gap). Land clearing, landscaping beyond what is listed, a pool house's interior and financing are not in it.

Where the range comes from

The pool
$73,000 to $204,000
800 sq ft of water at $90 to $250 a square foot (shell, excavation, plumbing, equipment, plaster). Steps and the sun shelf are part of the shell.
All-tile interior
$11,000 to $42,000
1,381 sq ft of shell at $8 to $30 a square foot above plaster. Tile is priced $4 to $30 a square foot as a finish, plus the extra labor over plaster.
Coping
$5,000 to $6,500
120 linear ft at $40 to $55 a foot.
Deck
$30,000 to $54,000
1,960 sq ft at $15 to $27 a square foot installed.
Hot tub
$6,000 to $18,000
A spa added to a new pool.
Raised tub wall
$2,000 to $8,000
The raised wall, where there is none.
Scuppers
$1,000 to $2,000
Each set. No source prices a scupper alone, so the sheer descent price stands in.
Wall for the water
$2,000 to $8,000
The wall that sheer descents and scuppers pour from, where none exists.
Pergola
$2,000 to $6,500
A 10 by 12 ft pergola. The one source is dated 2022.
Cabana
$7,500 to $31,000
Priced at $150 to $600 a square foot for a custom pool house, over this cabana's footprint.
Pool fence
$3,500 to $7,500
217 linear ft around the deck as drawn, at $15 to $35 a foot installed.
How we built this range, and the sources

We measure this design in the 3D model (water area, shell area, coping, deck, tub, what stands on the deck), multiply each quantity by a published price range per unit, add the lines and scale them for the state. The prices are from the pages below, collected in October 2026. Where two sources disagree the range spans both, and the line says so.

The method is written out, with every rate, at docs/POOL-IDEAS-COST-MODEL.md in our repository, and one file holds the rates, so a change of price changes every page at once.

How to get a number you can trust

Ask two or three local builders to quote the same scope in writing: the pool, the deck, the fence, the electrical, the permits and the landscaping, each on its own line. Then compare the lines, not the totals. Share this page with them: the size, the choices and the 3D model give a builder a starting point. To see how the published prices are built up and where they disagree, read inground pool cost, line by line.

How long it takes to build

From a signed contract to the first swim, before the yard additions.

Contract to first swim

3 to 6 months

Permits take from a few days to several months, depending on the town, before work starts. Weather, inspections and the builder's schedule move every date.

  • The yard additions are usually built after the pool is finished, so they add weeks that are not in this range.
  • The hot tub is built with the pool, so it adds days of plumbing and tile rather than weeks.

What it is made of

The materials list for this design, with its own quantities from the model.

The materials list (9 lines)
InteriorAll tile, blueabout 1,380 sq ft of shell
Small glass or porcelain tile over the whole shell. It is the most durable and cleanest looking interior, and the one with the most grout joints to keep tight.
CopingFlagstoneabout 120 linear ft
Natural, irregular stone. It looks like it was always there and needs its joints watched for movement.
DeckTravertine paversabout 1,960 sq ft
Natural stone pavers. Cooler than most paving in the sun, but porous: it needs sealing and a quick rinse after salt or chlorine splashes.
Pool fenceBlack aluminumabout 215 linear ft around the deck as drawn
Black aluminum pickets are light, strong and the usual choice for a barrier. Near salt air, ask for a marine-rated finish.
PlantingLawn and hedges
A lawn and clipped hedges. It softens the yard and brings grass clippings and fertilizer, so it should be kept away from the water.
Water featureScuppers
Copper or steel spouts that pour into the pool from a wall. They give the sound of water and need the wall they stand on built for them.
Yard additionCabana
A small open-sided shelter beside the pool: shade, a changing spot and somewhere to keep towels.
Yard additionPergola
A shade structure over part of the deck. It has to be anchored for local wind and snow loads.
Hot tubRaised, spills over, roundabout 850 gal
Built with the pool, with its own jets, heater share and cover. Tile and coping match the pool.
