DiRRep - Design Considerations
"Avoiding turning today's desperate needs into tomorrow's on-going despair"
Designed to be built by 2 to 3 people in less than a day, and for use under any climatic conditions, the DiRReP (Disaster Relief Re-locatable or Permanent Building) can accommodate up to 6 adults in relative comfort.
Complete Village or Township
Variation in site layout arrangements and elevation treatments make these units ideal for the creation of complete villages and townships. Where this is the intention, full town planning design, implementation and infrastructure services are offered on a Rapid Response basis.
Needing a footprint of 7.2m x 13.2m (to allow for projections – less if eaves are removed for terracing) each unit has wide overhanging eaves all round to provide veranda like sunshade and to throw roof-water away from the walls.
Each unit provides a fitted kitchen, with mini-cooker, flow through water heater, and shower-room with shower tray, washbasin and WC.
A cold-water header tank is mounted inside the roof space, with a cold-water hookup
point to serve both hot and cold points to kitchen and shower-room.
Delivering almost 35 sq m of fully usable floor space, each unit provides a spacious living room with galley kitchen and storage cupboards, a fully equipped showerroom, and one large sleeping area that can be divided in to two bedrooms by the simple addition of a solid or fabric wall.
Doors and windows at the front and rear of each unit can be opened to create through draft cooling. Additionally,a proprietary designed roof ridge can be provided for ‘open’ or ‘closed’ natural wind assisted ventilation and cooling.
Water and Sanitation
The units are designed to receive water either from a piped (mains) supply, or from a water-bowser. In the absence of either, guttering and rainwater butt roof-water collection can be provided.
While a flushing WC is included, this can be replaced by a dry ‘drop-through’, or ‘Elsan’ style unit if required (see below). Wastes from kitchen sink, washbasin, shower and WC (if provided) are taken through the floor for hook-up to irrigation or sewage disposal (see options below)
Water heating is via either a bottle gas or electric ‘flow through’ unit mounted in the
bathroom. Pipe-work, electrical harnessing, including power & lighting points are pre-assembled for fitting to wall panels, ready for quick ‘push fit’ connections to link these up to water and electric services, or optionally for operating from bottle gas and pumped in water (hand pump option available).
10 double power points for fitting at 1m height in selected panels, as marked. This
includes use of one socket for mini cooker and refrigerator if this option chosen. Power sockets are UK 13 amp standard, unless ordered differently. Wall or Centre light fitting included for truss over living and kitchen areas and each bedroom area.
Generators can be provided for autonomous operation, if required.
Each DiRReP is designed to withstand all but the fiercest earthquake at its
Unless more than one adjacent foundation pad is removed the DiRReP will remain standing and level.
The mechanical fixings and connections for each DiRReP are designed to provide resistance to hurricane force winds of up to 130 mph (208 kph), subject to some design changes. If orientated and erected correctly, the integrity of assembled components within a unit should not be compromised by anything but a direct hit
from a heavy object, e.g. ‘flying’ trees, poles, cars, etc. However, under very severe conditions, it is possible that the building could be moved on, or even lifted off its pad foundations. Protection against this can be obtained by excavating (by spade or auger) and concreting in an extended version of the screw ring beam leveller (see below).
