PROJECT

THE SALINE DOMES

Project details

Saline Dome investigates how architecture can emerge through the collaboration of salt crystallisation, microbial mineralisation, and computational form-finding. Located in a degraded inland salt-lake landscape in China, the project treats salt as an active non-human medium rather than an inert building material: it grows, collapses, repairs, and records environmental change. The design combines a cluster of dome frameworks translated from site parameters with layered salt-crystallisation fields that organically envelop along them, forming a hybrid system between ecological habitat, mineral scaffold, and limited human occupation. Salt-lake microbial communities participate in biomineralisation processes, helping to stabilise saline crusts and immobilise heavy-metal pollution within the structure. Rather than imposing a fixed architectural form, the project establishes environmental conditions for gradual growth, decay, and reinforcement over time. In this way, it rethinks human control in architecture and explores architecture as a continuously negotiated medium between machines, materials, organisms, and climate.

02 — Territory & Ecology

A lake under pressure.

Huama Lake within its territorial setting

Huama Lake within its territorial setting

01 / Territory

One lake within a larger salt landscape.

Huama Lake sits within the Dingbian lake group in China. Regional extraction, changing water levels and contamination frame the proposal: an intervention in an existing, inhabited ecology.

Lake sequence

02 / Change

The edge is not fixed.

The archived sequence records a changing lake boundary. This motivates a framework that can accommodate change rather than depend on one permanent shoreline.

Archived territorial sequence / dates remain in the original film.

03 / Living territory

The site is already a habitat.

Microbial communities and food webs occupy the same territory as environmental pressures. The proposal brings mineral accumulation and limited human occupation into this existing living system.

03 — Salt as Material Archive

Six forces. One changing lake.

These observations establish the context. Chapter 05 explains how selected fields guide design decisions.

01 / Heightfield

Where does water collect?

Terrain gives the other forces a spatial setting: high ground, depressions and the lake edge.

02 / Salinity

Where is salt available?

Salt availability is one condition for crystallisation. It is read alongside water and the other environmental fields.

03 / Heat

Where can evaporation be encouraged?

The heat study adds a thermal reading to the site. It informs the proposed relationship between exposure and evaporation.

04 / Wind

How does air move across the site?

The wind study introduces direction and exposure, later considered in the design of passages and openings.

05 / Algae

Where is biological activity present?

The algae layer makes microbial life visible within the environmental reading, alongside the mineral and climatic conditions.

06 / Heavy metal

Where is remediation relevant?

The metal study identifies a remediation concern. It motivates the proposal; it does not establish that a built structure would remove pollutants.

About the maps

Material observations at 2, 20 and 60 hours

01 / Material × time

Salt accumulates on a host.

Follow one gauze sample from its initial surface to 2, 20 and 60 hours in saturated salt solution. Deposits accumulate around the fibres: a support for growth, rather than a fixed finished skin.

Selected detail / The complete material matrix remains in Preview. These photographs record deposition, not material strength.

02 / Weaving

A network gives growth a pattern.

Over one week, deposits build along horizontal, vertical, cross-braced and random threads. The different openings remain legible, suggesting that the geometry of a host can guide the distribution of accumulation.

A separate one-week study, not an extension of the 60-hour experiment.

03 / Design interpretation

From a closed dome to an evolving host.

The dome is reinterpreted as a framework that supports a changing envelope. The material experiments inform this proposal; they do not demonstrate full-scale structural or ecological performance.

These photographs document salt deposition. Microbial stabilisation and pollutant immobilisation remain proposed mechanisms within the architectural system.

Choose where growth begins.

Metal, salinity and algae inform attraction. Food points define targets; emitters define starting locations. Terrain provides context, while wind and heat inform later exposure and opening studies.

02 / Network & selection

Connect, then compare.

Agent paths are reduced to network candidates. The eight SEED proposals are compared through six weighted criteria; Seed 03 scores 94/100 in this editorial assessment.

Comparison values are not measured remediation performance.

03 / Form & porosity

Give the field spatial form.

The archived study translates overlapping regions into connected volumes. The later opening studies explore passage through these forms.

The fitness field is translated into attraction points: locations that guide the simulated search.
EMITTER / Starting positions
Release points establish where agents begin exploring. They define the origin of the search, not its destination.

Starting positions and targets form the initial conditions. The paths between them emerge in the next stage.

06 — Host, Inhabitation & Time

A host for change.

Explore the original structural layers

01 / Structural host

Build the support first.

Arch ribs and knitted layers establish the initial framework. The assembly separates what is deliberately built from the mineral envelope proposed to accumulate around it.

Select Explode structure, then choose a layer to inspect.

02 / Envelope

The frame is only the beginning.

Mineral accumulation is proposed as an evolving layer around the support. Its thickness and openings become part of the enclosure, rather than a permanently sealed finish.

03 / Inhabitation

Shelter within a larger habitat.

Openings, routes and sheltered interiors suggest limited human occupation within the saline landscape. These are proposed spatial experiences, not recorded ecological outcomes.

04 / Time

Dissolution is part of the proposal.

Accumulation and dissolution are recurring states. The persistent framework is intended to support renewed growth as environmental conditions change.

07 — Architectural Views

Through the saline landscape.

From the wider lake to passages, thresholds and sheltered interiors — a visualisation of the proposed architecture.

01 / Landscape

A settlement within the lake.

Clusters of domes meet water and open ground. The proposal is read as a connected landscape, not a single enclosed object.

Domes approached across the shallow salt lake

02 / At the water’s edge

Approaching the domes.

Waterways, exposed ground and open thresholds offer different ways to approach the shelters.

Seen from above, the spaces between domes remain open to water, light and movement.

03 / Passage

Between mineral forms.

A human-scale route threads between the salt envelopes, connecting sheltered spaces to the surrounding lake.

Exposed fibres, filtered light and a small jetty bring the framework back into view. The enclosure remains connected to water and air.
