11 x 5 m Grecian pool
pool plan
An estate-class pool: resort presence at home, with room for swimming, play and lounging at the same time. At this size the supporting decisions matter as much as the basin — plan generous decks, a solid heat source and an automatic cover from day one, because every square metre of water is heated, treated and covered.
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.

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 | €41,000–€70,000 | Over a block or concrete shell; the least expensive route to any shape. |
| Tiled concrete | €62,000–€104,000 | A poured shell finished in tile; built to any shape, the most durable finish. |
| One-piece fiberglass | Not made at this size | Fastest to install; limited to sizes and shapes a mould exists for. |

Questions about this plan
- How much water does the 11 × 5 m pool hold?
- About 19,847 gal (82.8 tons of water) at 3′ 11″–6′ 7″ depth — computed from the actual pool outline, not a rule of thumb.
- How long does it take to fill?
- Roughly 2 days 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 561 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 11 × 5 m Grecian pool cost to build?
- Roughly €41,000 to €104,000 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.
