243 Irving Avenue is a 2 1/2 story, 5 bay, rectangular plan, brick, Colonial Revival, residential building. The c. 1920, slate-clad, side gable-roofed house is articulated by a classicizing entrance surround composed of paired engaged piers supported an entablature and framing a segmentally-arched leaded fanlight with matching sidelights. Matching engaged piers frame the gabled pedimented dormers which are fenestrated with round arched multi-paned windows. The matching, set back, 2 story, 2 bay, side wing is fenestrated with round-arched windows on the first floor. The remaining windows are 6/6 double hung with cast stone lintels and sills. By 2005, significant alterations were made to the property changing the front entry, removal of original windows, the addition of replacement windows, the removal of the round-arched windows on the side wing, and the addition of an attached two-bay garage set at an angle to the house proper.
