A ground-up construction & civil engineering firm with a <b>build-timelapse scrubber</b> — drag the timeline and an SVG tower assembles floor-by-floor from groundbreaking to topping out (crane, glass cladding, topping-out flag), a live <b>project cost estimator</b> (type + area + spec → budget / programme / peak workforce), a filterable projects grid, and a draggable <b>blueprint ↔ built</b> reveal slider that wipes the architect elevation across to the finished home. The build runs as a 7-section page with 342 words of real copy and 3 images, and it holds up from desktop down to a 390px phone screen.
