The Short Answer
For a Calgary firm, a realistic AI-optimized build lands somewhere between two and six weeks, measured from kickoff to launch. A lean site for a solo practitioner sits at the fast end of that range; a full rebuild across forty-plus pages with real content migration behind it sits at the slow end. What actually decides where a given project falls is page count, how much of the existing content survives versus gets rewritten from scratch, and how quickly the firm itself turns feedback around.
Set that against a conventional WordPress agency build and the gap is stark — those routinely run 8 to 16 weeks once you factor in design mockup rounds, a developer implementing everything by hand, and the back-and-forth that comes with hand-coding every page individually.
The Real Reason the AI Build Is Faster
This isn't quality getting sacrificed for speed — the time savings come specifically from where a traditional build burns its hours. A hand-coded WordPress project spends most of its timeline on a developer laying out each page manually, hand-writing schema entry by entry, and running fresh development passes for every revision cycle.
What AI-assisted development actually compresses is that mechanical layer — the page, schema, and structure production detailed on AI website design for Calgary law firms — while leaving untouched everything that genuinely needs a person: strategy, legal accuracy review, and compliance sign-off.
What Actually Moves Your Own Timeline
How fast the firm reviews and responds is the single biggest variable, ahead of raw scope — see how cost and timeline scale together. Turn feedback around in a day or two and a project stays near the fast end; let drafts sit untouched for two weeks and that delay lands directly on the launch date.
Migration complexity is the other lever worth watching — how a WordPress migration actually gets handled without losing rankings covers that side in full.
