In collaboration with Saentys, I built an interactive Webflow website for Helsfyr Atrium, a commercial property development in Oslo. The brief was to translate Saentys's After Effects motion designs into a Webflow build that preserves the cinematic feel without sacrificing performance.
The Webflow site uses Lottie animations and precisely choreographed scroll-driven motion to walk visitors through the building's design, location, and amenities. Each transition is tuned to feel native to the browser rather than ported over from a video timeline, giving the experience a polished, premium quality appropriate to the development's positioning.

The Helsfyr Atrium development in Oslo had a strong architectural story and a polished brand identity created by Saentys, but the motion-heavy After Effects animations they had produced could not just be dropped onto a website.
Property developers in Oslo's commercial market are competing for premium tenants who expect a digital experience that matches the quality of the physical space. A slow-loading video background or a choppy animation timeline would undercut the premium positioning entirely.
The core tension was between cinematic ambition and browser performance. After Effects timelines look gorgeous in a meeting room, but translating them to the web usually means compromising on load speed, scroll responsiveness, or visual fidelity. The client did not want to choose which one to sacrifice.
They needed someone who could rebuild the motion design natively in the browser, preserving the feel of the original animations while delivering a site that actually performs.
Beyond the technical challenge, there was a timing pressure. The development was actively leasing, and the website was the primary tool for introducing premium commercial tenants to the building before they ever set foot in Oslo. Every week without a live site was a week of missed leasing conversations. The Saentys team had done the hard brand and motion work; they needed a Webflow build that honoured it without compromise.
