Tiny Home Models Project

The Monroe County Board of County Commissioners approved in December 2018 the building of four “Tiny Homes” to serve as code-compliant models for residents who are rebuilding after losing their mobile homes during Hurricane Irma.

More than 4,000 homes throughout the Keys were destroyed or majorly damaged by Hurricane Irma. Many of these lost residences were mobile homes, which provided affordable/workforce housing. 

The County solicited vendor proposals to design and build four different resilient code compliant prototype Tiny homes on County-owned land. These replacement homes will be safer and better suited to survive future storms. 

After the model phase is over, these homes will become affordable County employee housing. 

Six vendors responded to the Request for Proposals (RFP) for construction of the tiny home models. These vendors submitted proposals for 26 combinations of tiny houses and land sites. There were fourteen different house types proposed. They ranged in size from 360 to 1,560 square feet and from an efficiency to a 3-bedroom, 2-bathroom home. 

The County selected four customized single-family home designs that will cost a total of $656,496 to construct. Here are the designs and locations: 

  • Ramrod Key: RAS Building Commissioning and Restoration will construct a metal box modular 2-bedroom, 1-bathroom home on a vacant lot located on West Indies Drive. It also is known as the “Stairway to heaven.” It will be 640 square feet, showing insulated walls and ceilings. Cost: $153,600. 
  • Cudjoe Key: Advanced Construction Technologies, LLC will build a “monolithic concrete structure” with proprietary material developed by “PermaHouse.” The 3-bedroom, 2-bath, 1,012-square-foot home will be on a vacant lot located on 1st Avenue West behind the Sheriff Office’s substation. It appears to be a panel made to the size of an expanded polystyrene foam core between welded metal meshes which are assembled on site and then overlaid with a 4,000-psi concrete mix much like that used to construct some in ground swimming pools.” Cost: $189,699. 
  • Big Coppitt Key: Cypress Community Development Corporation will build a factory constructed wood frame with insulated panels that are field assembled from kits. The 2-bedroom, 1-bath, 760-square-foot until will be built on a vacant lot at 28 Emerald Drive next to the fire station. Cost: $212,000. 
  • Key Largo: Cornerstone Design Build, Inc. will build a wood frame structure prebuilt in a factory. The 1-bedroom, 1-bathroom, 360-square-foot home will be built on a vacant lot at 39 Jenny Lane. The unit is fully assembled when site delivered. It is installed on the site foundation and connected to required utilities. The plans submitted say the siding is Florida approved Hardie board and the roof covering is asphaltic shingles. Cost: $101,197.
