Product Description

Lifeshelter LS4 is a temporary rehousing solution for emergency situations. This shelter provides an alternative to the use of tents and can be repurposed for permanent housing. The concept draws from housing construction methods that are an alternative to typical corrugated iron-sheeted roof structures, and the design allows for materials such as clay or limestone to be plastered for a solid structure.

Manufacturing/Building Method

This product is mass-produced and distributed through Lifeshelter ApS. This self-supporting building is assembled on-site and it is made of segments of panels following a catenary arch-form. Each arch is made of two curved panels supported by a steel component at the bottom and connected together at the top. The producer offer panels for houses 4 m wide. The space depth needed determines the number of segments of arches required.  The design allows the product to be disassembled, transported, and reused in a different location or as the primary part of the roof-structure in a future permanent house. The panels can also be dismantled and used as insulation material for walls or ceilings.

Design Specifications

The Lifeshelter LS4 can be assembled without complex tools. It is made from durable, low-weight components. It eliminates the need for external wood, steel, and screws, and the manufacturer claims it is stable during the course of an earthquake or storm. The Lifeshelter LS4 aims to be mobile and reusable for future dwellings. It features an arched structure that provides maximum space and strength to the shelter. Its modular design allows it to be adapted and configured for homes, schools, medical facilities, etc. The basic Lifeshelter LS4 eight arch-segments with 16 panels, has soft end walls, and has an area of 18 m². The weight and packed size of a complete packed shelter will consist of one package of 350 kg that can be broken down into smaller packages of weights suitable for transport by two people. The mass of each smaller package is no more than 50 kg. Package will contain: panels (11 kg each), PVC soft-end walls, metal frame, nylon straps, cover tarp, plastic connection tubes, and a tightening kit. The Lifeshlter LS4 is transported in shipping containers to the target context. For example, one shipping container of 40 ft takes 34 packed LS4's.

    I dunno, I feel like you’re kinda down on Corrugated Metal roofing. It is actually a very important product with both developed and developing country applications. It is cheap and provides for privacy in slum settings, and is typically the first building material people build with in informal settlements in urban areas (as opposed to earth & plants in rural settings). It may be better then to highlight best practices (roofing material with specific nail, requires: insulation, tiedown or toenailing, perimeter nailing) and challenges or concerns: prone to leaking if not properly installed, heat transfer without insulation or drop ceiling, minimal lateral strength as wall or roof diaphragm unless properly nailed, prone to uplift failure in wind or hurricane unless positively restrained.
