Plenumair
A monochrome, terminal-styled MVHR site: animated house cutaway, scroll-driven heat-recovery story, a voice assistant and a Part F airflow calculator.
A live, clickable build you can explore.
Plenumair asks what a ventilation brand looks like when it borrows its visual language from engineering drawings and terminal interfaces instead of stock photography. Everything is drawn in code: the house cutaway with air moving through its ducts, the loft-mounted MVHR unit with four spigots on top, the halftone project boards. One monochrome system, light and dark chapters, no photographs anywhere.
It is also a working demo of the tooling we fit to trade sites: a keyboard-summoned assistant that answers in text or voice and walks visitors to the right section, an airflow calculator that estimates a home's continuous extract rate the way Approved Document F does, and an enquiry form wired to a real inbox with WhatsApp alongside.
- Animated house cutaway hero with live airflow through the duct runs
- Scroll-driven 'MVHR in action' story: five stages, each lighting up its part of the diagram
- Interactive unit cutaway: hover a feature, the matching component highlights
- Voice assistant in a Cmd+K terminal (browser speech, no API keys)
- Part F airflow calculator with a send-to-WhatsApp estimate
- Enquiry form with honeypot and rate limiting, stored to Supabase

SC Installs
A redesign for a ventilation contractor trading since 1982: living airflow graphics, an interactive MVHR cutaway and nine optional business modules.
SCI · plant deck
A cinematic single-page concept for a ventilation installer: a real-time 3D plant deck in the hero, the day turning to night as you scroll, and the firm's own kind of job standing in for stock photography.
