Louis P. Thursby House, Historical residence in Blue Spring State Park, Florida

The Louis P. Thursby House is a two-story white clapboard house with a low-pitched white metal roof and two brick chimneys, standing in Blue Spring State Park. A covered veranda runs the full width on both levels, carried on square white columns with vertical white balusters as railings. Dark green shutters flank the windows, and wooden steps with a white handrail lead to the lower porch at the left. It was built from three kinds of center-cut pine milled in Savannah, Georgia, and shipped to the site by boat.

The house was built in 1872 as a two-story structure and received an additional floor with a kitchen extension in 1900. This expansion reflects how homeowners adapted their residences to changing living conditions.

The house reflects early settlement patterns along the St. Johns River, where steamboat traffic shaped commerce and connections between communities. The structure shows how pioneers oriented their homes toward waterways to participate in regional trade networks.

The house stands inside Blue Spring State Park in Orange City, on the inlet to Blue Springs off the St. Johns River. A small sign on a post by the wooden steps to the lower porch reads "NO TRESPASSING" and "KEEP OUT", so the veranda and interior are not open to walk through. Visitors view the white clapboard exterior, green shutters and two brick chimneys from the park grounds.

The pine was milled in Savannah, Georgia, then shipped by boat to the St. Johns River site. A cypress water tank once stood near the northeast corner of the house; it has recently been taken off its supports.
