About this home

Constructed 1852 - 1870. Patrick O'Donnell House. The grandest example of the Italianate style in the city. This monumental Charleston Single features a main house, separate guest house, pool and 3 car climate controlled garage. Solid masonry construction on 4 levels with triple tiered piazzas facing south. No expense was spared during a recent foundation to roof renovation. Copper roofs on main and guest houses, all new systems, wiring, plumbing, HVAC (recently replaced). Every inch of decorative plaster and interior, exterior trim was restored or replaced. This was not a "surface" restoration - it was taken to the bone. Main level rooms soar with 15' plus ceilings, grand door ways, windows, French doors, double drawing rooms 23 x 25 and 24 x 20 and a dining room that seats 18 (25 x 18) offer unmatched scale over anything available in Charleston today. Recent paint and decorating updates in most of the rooms. The grand kitchen was also updated in the last two years as well as heated pool and terrace added by a well known Newport landscape architect. This mansion is perfect for entertaining, raising a family. Truly the finest example of the period. Square footage is approximate, buyer to verify.
