The Grove is an excellent example of antebellum Greek Revival architecture. Among the distinguishing architectural features of the house is a full-height pedimented portico supported by four Tuscan columns, a prominent dentilated cornice extending around the building along the roofline, elaborate doors on both the first and second story, and a symmetrical, balanced interior floorplan, all of which are hallmarks of the Greek Revival style. The original main entrance of the house features double wooden doors flanked by unfinished paired fluted pilasters and columns, and elaborate sidelights. The original main entryway is also topped by an elaborate elliptical fanlight and a plain entablature similar in appearance to that extending near the portico roofline. The second story entryway has a similar appearance to the first story entry except the fanlight is plainer in design and a small balconet has been placed in front. This doorway was supposed to open up into a second story balcony but according to legend, the ship carrying the materials for the balcony was lost at sea and no attempt was made to finish the project.
