Site plans for the financier's secluded Caribbean island among the photographs.
Also contained in this new image drop seems to be a property layout for the Great St James island, found in the American territory.
Jeffrey Epstein bought a more modest island - Little St James - back in 1998, but acquired the larger adjacent island in 2016 for around $22.5 million.
This visual evidence suggest he had drawn up development schemes to build upon the sprawling island by building homes, an performance venue, an office beneath the waves and a pool.
Visible on the blueprint is Pillsbury Sound, a strait in the region, indicated on the lower right-hand corner.
The architectural drawing is covered in handwritten red notes and contains a notes section labelling different parts of the property.
Accompanying the main plan are what appear to be several other site drawings and engineering blueprints, featuring designs for boat shelters.
Further images disclosed as part of the current congressional release.
