Before finalizing the design, I ran qualitative usability testing on the low-fidelity design — not the final visuals — with the goal of understanding respondents' perceptions of content positioning, look & feel, user flow, and UI concept, and identifying where confusion or cognitive load might occur. The analysis focused on the why behind what respondents did and said, rather than counting how many said what.

5 respondents were recruited matching Kopola's actual target client profile: income 20–40 million IDR/month, age 30–45, based in Greater Jakarta, Yogyakarta, or Bali, working as civil servants or private company employees, and either having used an architect before or actively looking for one — captured well in one respondent's own framing: "I need a trustworthy architect that can fulfill my dream house."

In-depth interviews were structured page by page — Homepage, Detail Page, About Page, Contact Page — each anchored by a main comprehension question (e.g. "Can you tell what Kopola does?") followed by specific probes on what drew attention, what they expected from certain actions, and what they'd prioritize.

Homepage findings: Respondents understood Kopola's specialty and "make dream come true" brand mantra, and liked being able to see the studio's work within one scroll. But the project list undercut that: black-and-white thumbnails took longer to read than the color hero image above them, the thumbnails felt too small, title/year text blocked the image itself, the red rectangle accent felt disturbing without adding value, and the number of projects shown by default risked cognitive overload and drop-off on a first visit.

Detail Project findings: Respondents appreciated seeing a bigger project preview, but repeating the title and cover image they'd already seen in the list felt redundant, the description text column was too wide to read comfortably, and respondents wanted to compare description against images without having to scroll up and down repeatedly.

About Page findings: The studio's selling point came across clearly and testimonials were reassuring, but respondents expected concrete service information (budgeting documents, interior sourcing, contractor coordination, 3D views, revision policy) — content the page didn't yet have. One respondent summed it up directly: if the page was only going to promise what Kopola could do, it would be more useful folded into the homepage than kept as a separate page.

Contact Page findings: No usability issues here — the one request was to surface contact info (email/phone) in the top navigation so it's reachable from anywhere on the site, not just the Contact page.

These findings — not personal design preference — directly shaped what changed between the low-fidelity design and the final site.
