Scroll-Driven 3D Real Estate Experience

The Client

A Dutch real estate developer with a portfolio of major urban transformation projects across the Randstad — converting underutilized commercial buildings into high-end residential living spaces.

They had an existing website that served its purpose but did not match the premium positioning of their brand. They needed a digital presence that could stand alongside the top-tier real estate developers in the Netherlands.

The Challenge

The client came with a clear visual benchmark: a site on the level of award-winning real estate developer websites — cinematic scroll-triggered animations, smooth parallax effects, and a bold dark aesthetic. The centerpiece: a 3D flyover animation of one of their flagship projects that would play as users scrolled through the homepage.

This is fundamentally different from embedding a video. It demands frame-perfect synchronization with scroll behavior in both directions — scroll down to fly forward, scroll up to fly back.

What We Built

The 3D Building Flyover

The flagship feature: 298 individually rendered 3D frames drawn to an HTML5 Canvas element, scrubbed precisely based on scroll position. As users scroll, they fly over the city and zoom into the building.

Getting this to feel smooth required solving several hard problems. Early iterations had visible frame tearing, stuttering on fast scrolls, and memory issues. We implemented a preload-all strategy with a loading progress indicator, aligned canvas rendering with the animation timeline, and added frame index clamping to prevent rendering artifacts.

Scroll-Driven Animation System

The entire homepage is designed as a single continuous narrative. Every section has scroll-triggered animations — fade-ins, parallax shifts, sticky elements that progress as you scroll. We synchronized the smooth scroll engine with the animation library to ensure both agree on scroll position at all times, eliminating desync issues.

The Full Site

Beyond the flyover, we built:

Animated text sequences — cycling words that reinforce the company's scope
Featured projects grid — portfolio showcase with hover effects revealing project details across 10+ projects spanning 8 years
Sticky approach section — numbered methodology steps that progress as you scroll
Animated statistics — counters that tick up as they enter the viewport
CMS integration — headless CMS for content management, ready for the client to update projects and news independently
Custom design system — near-black backgrounds, off-white text, and a gold accent reflecting the luxury real estate positioning

Developer Experience

The client works across multiple devices synced via cloud storage. We created custom scripts so the client can run the dev server and deploy without touching the command line — just double-click a file and the site builds and deploys automatically.

The Result

90+ Lighthouse performance score across all categories
Smooth 60fps scroll animations across modern browsers
298-frame 3D flyover running flawlessly on scroll
Auto-deploy pipeline — changes go live within minutes of a commit
Fully responsive — optimized layouts for desktop, tablet, and mobile
SEO-ready — server-rendered pages with proper meta tags and structured data

The site transformed the developer's digital presence from functional to premium — matching the quality of their real-world developments.
