Attic Bases for Classical Order Columns

 

 the Design of the Standard Attic Base

Attic Base Design

Attic Bases are used with the classical Orders of columns Doric, CorinthianIonic, Scamozzi, Composite, and Temple of the Winds (Tower of the Winds). Unlike the simpler Tuscan Bases, Attic Bases have two rounded profiles (Torus) that are separated by a hollow concave or recessed area (Scotia) that sits on a Square Plinth. The Torus and the Plinth in some cases can be made separately.

 Custom Attic Bases

 

Replace rotted Attic Bases with a traditional solid hardwood preferably White Oak made to any custom size. We welcome precise Historic Reproductions. Hardwood is load Bearing made up to 36" Diameter. Specify the Torus or Plinth separately if required

 

The GFRC-ZeamentTM is a Portland Cement with a very smooth finish. The Attic bases are hollow to wrap around a column shaft, and the Plinth, although hollow, is strong enough to be load bearing.

 

For those that require a decorative wrap select ArchPolymerTM  an artificial wood. All can be ordered split for post wraps. For larger decoratives specify Fiberglass

Sizing Your Replacement Bases

Measure the circumference of the bottom of the shaft before it engages the base. The best way to size the base is to tape a piece of string to one side of the shaft, go all around the circle and note the length. The length of the string is the circumference of the bottom of the shaft before the base.  The length times 3.14 will equal the diameter required for the hole in the base. You need wiggle room so add a 1/4".  Before considering custom sizes, select from the standard models below.

GFRC-ZeamentTM Attic Bases

 

To replace rotted or broken bases, GFRC-ZeamentTM is the perfect solution! It is a composite of Portland cement and polymers producing a smooth exterior finish. It is strong, heavy and load bearing. The Torus and Plinth are hollow, however the Plinth is wide enough to carry column loads. Custom sizes are available from 6" to 48" diameter. Large bases are made in 2 parts Torus and Plinth or split for reassembly around an existing column shaft.
