Historic Ellicott City Inc. announced last week that the 28th annual Decorator Show House is the historic Mount Ida, the mansion formerly belonging to the Ellicott family.

Located at 3691 Sarahs Lane, the house will be open to the public from Sept. 28 through Oct. 27, 10 a.m. – 4 p.m. Tuesdays, Wednesdays, Fridays and Saturdays, 10 a.m. – 8 p.m. Thursdays and noon to 5 p.m. Sundays. Doors close one hour before closing.

The mansion has gone through three months of renovation at the hands of 12 designers under the direction of HEC Inc.’s design chair, Carroll Frey. Mount Ida was the Decorator Show House in 1995, and in 2011, HEC Inc. moved its headquarters to the building.

According to a release from HEC Inc., Mount Ida was built in 1828 by Charles Timanus for William Ellicott, grandson of one of Ellicott’s Mills’ founders. In the 1850s, the mansion became the home of Judge John Snowden Tyson, whose family lived in the house until the 1920s. The last Tyson to live in the house was Ida Tyson, for whom the mansion is now named.

The building is currently owned by the Miller Land Company.

Tickets for the house show are $15 in advance and $20 at the door, and are available for purchase at www.HECMD.org or by calling 410-461-6908. Tickets can also be purchased at several Howard County locations including the Antique Center in Historic Savage Mill, Clark’s Ace Hardware, Ellicott’s Country Store, the River Hill Garden Center, Shoemaker Country, the Pink Cabbage, Westwood Unique Furnishing & Antiques, and in Carroll County at Sidetracked in Westminster.

No infants or children under the age of 10 will be admitted, and HEC Inc. is requesting all visitors wear flat shoes only and turn off cell phones while in the house. No indoor photography is permitted. The house is not handicapped accessible.
