Deck Cost Calculator
Get an instant ballpark price for your deck — in under a minute.
Timber or composite, ground-level or raised. No phone calls, no waiting.
Thinking about a deck but not sure what it'll cost? This calculator gives you a quick, honest ballpark based on your deck's size and the material you choose — enough to know if your dream deck fits your budget before you talk to anyone.
This is a provisional estimate based on average South African rates, meant as a ballpark. Your final price depends on your site, access, finishes and design — which we confirm with a proper quote after a site visit.
How it works
1. Enter your deck. Size, and pick your material — pine, hardwood or composite.
2. See your estimate. An instant ballpark price range, right on screen.
3. Want a real quote? Leave your details and a deck specialist comes back to you with a proper, site-specific quote.
Why OFFplan
We're an NHBRC-registered team building timber and composite decks across the Garden Route, from Plettenberg Bay to George. We build every deck the way the manufacturers intend, so it lasts in our coastal conditions.
How accurate is the estimate? It's a ballpark to help you plan. The real figure comes from a site-specific quote — but this gets you in the right range.
What does a deck cost per square metre in South Africa? It depends mostly on the material: pine is the most affordable, hardwood and composite cost more. The calculator works it out for your size and choice.
What's included? The estimate covers the deck build for the size and material you pick. Extras like railings, stairs, roofing or removing an old deck are quoted separately.
