Valueguard has published a quality-adjusted price index (HOX®) for Swedish properties since 2005, and real estate professionals use their valuation service, Värderingstjänst, for data-driven decisions. The platform was running on outdated technology, and the project scope was a full redesign.


Valueguard's valuation service holds detailed data on every property sold or listed in Sweden, with search, filtering, and market trend tools for agents.
I worked alongside Stefan Walet, Valueguard's Chief Production Officer, and Caroline Gard, a senior developer at Mpya Digital, on the UX and product design.
The existing platform was powerful but hard to use, built up over years by engineers without dedicated UX support. Talking to Valueguard's top clients surfaced four issues:
Users also ranged from power users relying on every feature to occasional users sticking to the basics, so the redesign had to work for both.
We focused on three things: personalization for individual users, customization so people could adjust the layout themselves, and efficiency features like keyboard shortcuts and touch gestures for power users.
Stefan Walet, Caroline Gard, and I mapped every part of the platform across a series of workshops, from screen layouts to map filters, refining the core flows:
Those flows shaped a set of layout principles:
We built a working React prototype to test the design in real scenarios, then added Hotjar to track how Valueguard's team actually used it once it reached their hands.

Some assumptions didn't hold: the top-right filter button placement worked fine despite initial concerns, and the expand/collapse slider for the side menu was intuitive without instruction.
After several rounds of adjustment based on that data, the design moved into full development.

Redesigning a mature product with real, demanding users taught me more about prioritization than building something new would have. Every change had to be justified against how agents actually work day to day.
