HLDC houses are built using traditional construction methods. The models are of reinforced concrete foundation and floors; the walls are of reinforced concrete blocks. All units are serviced with portable water and electricity, mainly 220v and septic tank for sewerage services. Roofing is of galvanize (heavy duty sheets) with 30 degree slope; wall finishes include masonry plastering and painting; floor finishes are ceramic tiles. Cabinets, cupboards and closets make up the furniture of the units. These houses are designed under the guidelines of the building codes. 

Since its inception in 2003, the HLDC / PIU has improved the living conditions of hundreds of Vincentian families. Over five hundred (500) new homes, which include low income homes, middle income homes, as well as no income homes and some relocations for the IADC, have been constructed. Also, many families have also benefited with material assistance in retrofitting their existing homes under the no income project.
