Under-truss screen enclosures (also referred to as lanai’s) are built underneath the ‘truss’ roof of a home using the structural supporting elements of the home, much the same as a front entryway enclosure.
Once screened-in the patio space serves as a transitions space that keeps bugs and pests out, can prevent pets from escaping, and provide an area for outdoor area.
Most developer or general contractor built homes in Florida unfortunately leave off these under-truss lanai’s… But we can certainly get them done.
