Chambers, Thomas Jefferson, House
Also known as: Chambers Octagon House
Why it's listed
Built between 1862 and 1865, this one-story wood frame house at 624 Milam Street in downtown Liberty, Texas, follows the octagon plan promoted in the mid-nineteenth century. Thomas Jefferson Chambers is believed to have built it. Five of its eight sides remain in their original form, with a kitchen wing extending from the east side that may date to about 1865. The house sits on brick piers and has a central brick chimney, clapboard siding, and groups of wood sash windows, many with old glass. Changes include a small bathroom addition in the early 1900s and a bedroom addition and interior remodeling in 1960. The house is considered locally significant for its architecture. Octagon houses were popular only briefly, and just fourteen octagon buildings have been identified in Texas. This is the only one known in Liberty County. It has remained in the Chambers family and is one of the oldest buildings standing in Liberty. It was designated a Recorded Texas Historic Landmark in 1978.
Significance in brief: The house is an excellent example of the mid-nineteenth century octagon mode and is the only known octagon building in Liberty County. Only fourteen octagon houses or other buildings have been identified in Texas. Most of its original structure survives, with limited additions in about 1900 and 1960.

What listing means for this property
National Register listing is honorary for a privately owned home: it does not by itself restrict what an owner may do with their own money, and it does not require public access. Restrictions come from local landmark or historic-district ordinances, which are separate (how they differ).
Owner-occupied houses are not eligible for the 20% federal rehabilitation tax credit, which applies to income-producing buildings, but many states offer credits for homeowners. Listing also opens the door to preservation easements and to buying a plaque. Start with what listing means for homeowners, renovating a listed house and selling one.
General information, not legal or tax advice. Rules change; confirm with your State Historic Preservation Office or a qualified adviser.
