Pie in the Sky: A 300-Metre Hydrogen Airship That Moves the Farm to Wherever the Weather Is Good

Architecture almost always starts by accepting the ground beneath it. Pie in the Sky refuses that premise. Its subtitle, "I'll farm where the weather is good," carries the whole argument: if fertile land and reliable seasons vanish from the surface, the farm should follow the sun instead of waiting for it. The result is a habitat whose only fixed relationship is with the atmosphere it travels through.

Designed by Habiba Mukhtar and recognised as an Editor's Choice entry in Architecture of the Apocalypse 2020, the proposal imagines a future shaped by slow, compounding collapse: harsher weather, disrupted ecosystems, resource scarcity and atmospheric deoxygenation. Rather than fortifying a settlement on damaged ground, Mukhtar lifts a community of around 160 people into an approximately 300-metre-long rigid, hydrogen-powered airship. Its program includes family homes, productive landscapes, research laboratories, observation decks and workshops. The project sits somewhere between building, aircraft, greenhouse and miniature city, and it is most compelling where it refuses to choose.

A Section Drawn as a Metabolism

The cutaway section explains the project better than any exterior view could. Stacked, timber-clad volumes fill the interior, and numbered diagrams trace water, heating and exhaust air as they move through them, with white arrows mapping how air circulates between floors. This drawing shows the brief's central rule in practice: nothing arrives from outside the system. Water is captured, filtered and reused, waste becomes material, and food production is built into the habitat rather than added on.

What deserves credit here is the decision to draw infrastructure as part of the architecture instead of hiding it behind the occupied spaces. In a closed ecological cycle, the services are the building. Making those flows legible in section turns survival logistics into the primary spatial organiser, and it shows that Mukhtar sees the airship as an environmental machine first and a vessel second.

A Cellular Lattice Where Cargo Used to Be

Mukhtar borrows from contemporary airship engineering, especially variable buoyancy and heavy-load transport, and then reassigns the payload. Homes take the place of cargo containers, and greenhouses take the place of freight. The faceted, dome-like framework in the first rendering supports this shift. Its irregular cellular lattice of dark members and pale openings reads as a structure that is both lightweight and porous, a fitting language for an enclosure that has to manage light and air while staying aloft.

The accompanying plan presents an oval footprint with two lattice-roofed halls, stepped terraces and dimensioned lengths running along its edge. The terracing suggests a ground plane cut into levels, which matters for a habitat that must hold farmland, dwellings and shared space within one envelope. Laid next to the lattice study, the plan shows the internal urban structure that keeps the payload-as-architecture idea from staying a slogan.

Timber Rooms, Roosters and a Glowing Fourth-Floor Bridge

The interior renderings bring the speculation down to the scale of daily life. In one, angular windows cut through a timber wall while silhouetted figures sit and stand nearby; a rooster wanders the grated floor, and curved pipes run underneath. That small detail of livestock on a perforated deck, above exposed services, captures the project's ethos neatly. Agriculture, inhabitation and infrastructure share the same few centimetres of section.

The second view moves up to a fourth-floor bridge, where a lone figure stands between bamboo in the foreground and the lattice dome above, set against a glowing ceiling. The atmosphere is calm, almost pastoral, and that is intentional. A community that can travel slowly when conditions are good, hover when it needs to and relocate quickly ahead of a storm has turned climate into a navigational parameter. Sunlight becomes a destination and storms become things to steer around. These interiors show what that freedom feels like from the inside: unhurried, planted and quiet.

Why This Project Matters

Most apocalyptic proposals respond to catastrophe with walls, bunkers or sealed domes, all of them ways of staying put and enduring. Pie in the Sky offers a different survival strategy built on mobility. By treating the sky as a site and weather as a route, Mukhtar questions one of the discipline's deepest assumptions, that a building's identity depends on a fixed piece of land. The project argues that resilience could come from movement and responsiveness rather than mass.

It also holds its fantasy accountable. Grounding the concept in a section of water, heat and air flows, a structural lattice and a terraced plan keeps the closed-loop premise from turning decorative. Whether or not a 300-metre hydrogen village ever leaves the ground, the proposal leaves a clear lesson for designers working on the ground today: treat resources as cycles, make infrastructure visible, and let climate shape how a place behaves, not only where it stands.
