7 x 4 m Grecian pool
pool plan
A full family pool: a shallow end where kids stand and games happen, a proper deep end for diving-free swimming, and enough length that two people can swim without negotiating. This is the most-built size class in private gardens for a reason.
The Grecian pool clips the rectangle's corners at 45°, giving an octagonal outline that reads formal and deliberate without a single curve. It keeps nearly all the rectangle's swim length, and the angled corners make elegant seats for steps, benches or planters at the pool's edge.

Figures are computed from the sampled pool outline and the plan's depths — the same geometry the 3D designer uses. Excavation includes shell and working allowance; your site conditions may differ.
What it costs to build
A rough installed-cost range per construction type, at this size — the pool itself, with basic coping. Not a quote.
| Construction | Installed cost | Note |
|---|---|---|
| Liner or membrane | €26,000–€45,000 | Over a block or concrete shell; the least expensive route to any shape. |
| Tiled concrete | €40,000–€66,000 | A poured shell finished in tile; built to any shape, the most durable finish. |
| One-piece fiberglass | €23,000–€40,000 | Fastest to install; limited to sizes and shapes a mould exists for. |

Questions about this plan
- How much water does the 7 × 4 m pool hold?
- About 9,362 gal (39.1 tons of water) at 3′ 11″–5′ 11″ depth — computed from the actual pool outline, not a rule of thumb.
- How long does it take to fill?
- Roughly 24 hours from a standard garden tap (~6.6 GPM). A water delivery service fills it in a few hours.
- Is this size right for my garden?
- The water surface is 282 sq ft; plan roughly 1.5–2× that footprint including the surrounding deck. Open the plan in the designer and set your own deck margins to see the full footprint.
- Can I change the depth or edge type?
- Yes — open the plan in the designer and adjust depths, edge system (skimmer, deck-level overflow or raised), finishes and accessories freely.
- How much does the 7 × 4 m Grecian pool cost to build?
- Roughly €23,000 to €66,000 installed at this size, depending on construction type — before deck, fence, landscaping, heating or permits. See the cost table above for the range per type.
