Following Hurricane Katrina, the State of Mississippi was awarded a grant from the FEMA-funded Alternative Housing Pilot Program (AHPP) to develop a prototype alternative disaster housing unit. In my role as a Housing Recovery Specialist for FEMA in Mississippi, I designed a number expansion options to those units to allow them to function as permanent housing and promote greater acceptance by the local community. Several of these expansion designs where successfully built by local Habitat for Humanity affiliates. For more information, go to

  • In order to make a duplex work, it needs a roof over the two joined modules. That would be simpler and more economical to accomplish if you start out with a flat roof and parapet.

  • MISSISSIPPI COTTAGE PROGRAMEXPANSION ALTERNATIVESProject Goals:•Enhance the long-term livability of the cottages•Enhance the curb appeal of the cottages in the context ofthe neighborhoods where they are located 3
  • MISSISSIPPI COTTAGE PROGRAMEXPANSION ALTERNATIVES •Single module: Expands the front living space and widens the façade of the cottages to be more compatible with surrounding homes. •Dual modules: One module expands the front living area and one adds an additional bedroom and bath.•Combinations: Two Park Models or twoMS Cottages combined to create bothsingle family and duplex dwellings 4

Asimilar single family version or a duplexcould be created by combining two MSCottages. 5

  • FEMA ALTERNATIVE HOUSINGRECOMMENDATIONSFrom the onset of a disaster: •Prepare engineered drawings for expansion options as part of the project budget •Seek public-private partnerships for initial placement of disaster units to facilitate their ultimate permanent placement upon the same property •Build models of expanded permanent cottages to garner community support for permanent placement•Incorporate pre-framed openings and mechanical stub-outs to simplify expansion•Maintain the same roof pitch across modules tofacilitate combining models.•Make Park Model HC adaptable even if not fully UFAScompliant to facilitate use as senior housing. 47
  • FEMA ALTERNATIVE HOUSINGFUTURE MODULE ALTERNATIVES•Consider an alternative Park Model that is less a scaleddown version of a single-wide mobile home and morelike a compact hotel studio suite that will accept fullsized bedroom furniture. This will facilitate utilizing it asan expansion module for a larger module•Consider constructing units with a flat roof and/orwithout a front porch in a manner that a pitched roof andporch could be added later. This would result is initialcost savings, greater flexibility for expansion and agreater variety of porch and roof styles once the unitsbecome permanent.•Consider constructing a portion of the modular unitswith mirror imaged floor plans to facilitate combiningmodules to create permanent duplexes 48
  • FEMA ALTERNATIVE HOUSINGFUTURE DESIGN OPTIONS2 BR 1 BA MODULESpecific recommendations:•Relocate washer/dryer to hall closetinstead of in the open hall•Reconfigure handicapped accessiblebath to allow access directly frommaster bedroom•Relocate rear door to allow potentialfuture use as a duplex (requires mirrorimaged floor plans for a portion of theunits) 49
