A house that you slice like bread and reassemble elsewhere instead of wrecking ball — that's the core of Michael Jantzen's Segmented Building System, a concept now trending again after Yanko Design feature Nov 9.
Jantzen, Santa Fe artist-designer whose work showed at MoMA and National Building Museum, treats building not as permanent shell but as series of discrete 4-foot-wide sections. Crucial: 4-foot is segment width, not room span. Each slice is a profile combining floor, wall and roof into full or half module. Build ten slices, you get 40-foot long house. Add half-profiles, you branch sideways into L or U.
Made from Structural Insulated Foam Panels (SIPs) — foam core bonded between two faces — pieces can arrive separately or pre-assembled. Jantzen proposed mustard-yellow prototype but cladding is open: metal or cement-composite boards applied before delivery or on site.
Most interesting trick is misalignment. Instead of flush joint, slide neighboring profiles out of alignment by few inches. Fill gap with glass. Suddenly joints become narrow vertical slots for daylight and ventilation — roofline follows and creates sculptural rhythm, not just box.

Segments attach to prefabricated concrete perimeter foundation shaped to chosen layout. Relocating still means preparing new base and reconnecting services — electricity, plumbing, HVAC. This is reusable sections, not drop-on-any-plot caravan.
Environmental claim is simple: construction waste is 36% of global landfill. Modular speeds build, but segmented attacks demolition. When family grows, add slices. Shrinks, remove. Moves city, truck slices. Usable parts stay intact.
Concept dates to 2016, no built project yet, but aligns with three growing trends:
Reconfigurable housing — like Evolution Cottages that expand via wings/knuckles, but Jantzen slices instead of adds.
Reusable modules — unlike container homes (HomeModule's 4 steel boxes) that lock size, 4-ft granularity offers more adaptation.
Off-grid ready — designer proposes solar panels, off-grid operation; SIPs provide high insulation for India's hot zones.

For India, where 11 million homes shortage meets migration and rental markets, 4-foot slice could mean affordable incremental housing in Chennai's Wallajah Road area — start with 2 slices (8x12 ft), add 2 later. Prefab foundation suits flood-prone sites.
It is still concept. No cost, no structural testing for cyclone/seismic. But idea reframes housing as furniture — not permanent, but reconfigurable life infrastructure.
