ExoSett Reconfigurability

The accommodation frame supports each pod independently, while the service frame provides the framework for access and utilities. In conventional stacked modular construction, modules commonly support those above them. ExoSett separates pods from that primary load path, allowing removal without disturbing the structural support of their neighbours.

The building must also provide for pod insertion and removal, handling equipment and accessible service connections. Reconfigurability is designed into the building from the outset.

The existing machine-readable XML building model records the building’s arrangement. The fuller building specification is intended to define or reference dimensions, connections, tolerances, service interfaces and verification requirements. This engineering specification remains under development; XML schema validation alone does not establish engineering conformity.

The building designer, frame designer, pod designer and services designer must coordinate these requirements, including service isolation and reconnection while neighbouring homes remain in use.

The specification should be version-controlled and maintained throughout the building’s life, so replacement components can be manufactured against the applicable requirements years or decades later.

A physical jig provides a reference for checking critical component dimensions, connections and clearances before installation. Each jig must first be measured against its specification and tolerances. Both accommodation frames and pods can then be checked against the specified interfaces.

Different manufacturers can use their own materials and manufacturing methods, provided their components meet the applicable requirements. Jig testing establishes conformity only for the requirements it covers; it complements structural, fire and other safety verification.

Pods can be replaced, refurbished, repurposed or relocated to buildings with compatible specifications as requirements change. This allows buildings to evolve without wholesale demolition or rebuilding.

Every change must preserve the applicable structural, safety and operational requirements, with the design record updated accordingly. The specification and conformity records provide evidence for assessing whether components remain suitable for use.

ExoSett aims to support a competitive manufacturing ecosystem in which independent suppliers can produce compatible components to common specifications. This would reduce building owners’ dependence on a single manufacturer’s continuing existence or product range.

Compatibility is determined by the applicable specification, not simply by the ExoSett name. The manufacturing interface standards, jig definitions and certification procedures needed to demonstrate interchangeability are still being developed. Interchangeability across independent manufacturers has not yet been demonstrated.
