Sentinel+

Sentinel+

A modular hard-cover structure system for durable shelter and infrastructure in prolonged displacement and service delivery contexts.

Sentinel+ is designed for situations where lighter shelter solutions are no longer appropriate, and where greater durability, security, and environmental resilience are required.

Sentinel+ is intended for contexts where prefabricated or container-based shelter and infrastructure solutions are commonly used, but where long-term adaptability, repairability and cross-compatibility are required.

The system supports a wide range of uses across displacement, recovery, and operational settings — while retaining flexibility to adapt over time.

Intended use

Sentinel+ is commonly used for:

housing in prolonged or semi-stable displacement contexts
health facilities and clinics
WASH facilities, including toilets, showers, and hygiene blocks
communal kitchens and food preparation spaces
classrooms, training facilities, and learning hubs
operations, administration, and coordination centres
staff accommodation
shared and community facilities through the CommUnity Spaces approach

Configuration and layout

Sentinel+ is built around a shared structural system that allows units to be configured in multiple ways to suit site conditions and programme needs. Units can be deployed as:

standalone structures
linked rows for housing, kitchens, or administration
hub configurations for clinics, learning, or community services
corridor-connected layouts that protect movement and operations in all weather

Structures can be combined, extended, or reconfigured over time without demolition or material waste. Unlike fixed-layout units, Sentinel+ is designed around a shared structural and panel system, allowing components to be reused, reconfigured, and maintained across different functions over time.

Structural and climate performance

Sentinel+ uses a hard-panel wall and roof system designed for durability, security, and prolonged exposure. Key considerations include:

suitability for long-term outdoor use
options for on-ground or raised-floor installation, depending on flood risk, terrain, and site conditions
integrated anchoring and grounding systems to improve stability in high-wind, monsoonal, and severe-weather environments

These features support reliable use across a wide range of climates and contexts.

Localisation, logistics and waste reduction

Sentinel+ is designed to support responsible delivery and stewardship. Where feasible:

panels and components can be manufactured regionally to support local capacity
systems can be supplied as flat-packed kits to improve container efficiency
components are reusable, repairable, and replaceable rather than disposable

Deployment approaches from component kits to higher levels of pre-fabrication are selected in partnership with agencies and donors based on urgency, site conditions, and logistical constraints.

Services and power readiness

Sentinel+ structures are designed to integrate with essential services over time, including:

solar power and energy storage
lighting, ventilation, fans, and heating where appropriate
cooking, water, and sanitation systems

This supports coordinated site planning and reduces the need for multiple parallel infrastructure solutions.

Durability, stewardship and standards

Sentinel+ is intended for use beyond immediate emergency timelines. The system:

uses reusable, repairable and redeployable components
is designed to reduce lifecycle cost, waste, and repeated replacement
supports long-term stewardship of infrastructure assets
is designed to align with relevant UN SDGs and UNHCR shelter and infrastructure guidelines

Confidence for donors. Clarity for partners. Dignity for communities.
